In the ever-evolving landscape of energy storage technologies, the lithium–sulfur (Li–S) battery stands out for its promise to deliver unmatched energy density and reduced costs compared to traditional lithium-ion batteries. However, progress toward commercial viability has been hampered by complex electrochemical challenges, particularly those involving interfacial charge transfer dynamics. A new study, recently published in Nature, unveils groundbreaking insights into the intricate reaction pathways occurring at solid–liquid interfaces within Li–S batteries, illuminating mechanisms that govern lithium sulfide deposition under realistic, lean electrolyte conditions.
The difficulty in understanding and controlling the conversion of lithium polysulfides (LiPSs) during battery cycling stems largely from the dynamic and highly concentrated nature of reactant distributions at the electrode–electrolyte interface. In these environments, the balance between surface-bound and dissolved species dictates the overall electrochemical performance. The new research deploys advanced in situ liquid-cell electron microscopy techniques to directly visualize these sophisticated concentration gradients, a feat that has eluded scientists due to the liquid phase’s complexity and the scales involved.
What emerges from this study is a revelation of concentration-driven phase segregation phenomena right at the interfacial layers, termed high-concentration interfacial layers (HCILs). These HCILs form as LiPSs aggregate in the immediate vicinity of the electrode surface during cycling, dramatically altering the local reaction environment. This segregation is not merely a passive occurrence; it actively directs charge-transfer dynamics by establishing competitive conditions between surface-mediated and solution-based pathways. The delicate interplay in these zones influences where and how lithium sulfide (Li₂S) nucleates and grows, directly impacting the battery’s capacity retention and cycling stability.
Complementing the microscopy observations, computational explorations using density functional theory (DFT) provide a molecular-level understanding of how LiPS clusters modify their electronic structure upon aggregation. The study identifies that the molecular geometries and orbital hybridizations evolve as LiPSs coalesce, resulting in enhanced electronic interactions that facilitate charge transfer through the concentrated clusters. This phenomenon fundamentally challenges previously held models which treated LiPS species largely as isolated entities, offering a new paradigm that accounts for collective behavior in highly concentrated solutions.
The practical implications of these mechanistic insights are far-reaching. By comprehending how HCILs govern interfacial reaction pathways, the researchers have engineered electrodes that strategically balance surface and solution reactions amidst high LiPS concentrations. These meticulously optimized electrodes enable impressive fast-charging capabilities—reaching rates up to 4 C with current densities of 26.8 mA cm⁻²—without compromising energy density, which itself surges beyond 400 Wh kg⁻¹. Such milestones represent a substantial leap forward in the achievable performance metrics for Li–S battery technology.
This study’s significance extends beyond the immediate Li–S chemistry, addressing a broader challenge in electrochemical energy conversion: capturing and controlling complex interfacial phenomena under dynamically varying concentrations. The in situ liquid-cell electron microscopy method establishes a powerful approach for observing reactive species and phase evolution directly in their native electrochemical environment. As such, it holds promise to transform research across a host of energy storage and catalysis systems where interfacial reactions dictate overall function.
Notably, this work also clarifies why lean electrolyte conditions—essential for practical high-energy devices—have historically been so difficult to optimize. The rich detail uncovered concerning phase segregation and charge transfer competition suggests that managing HCIL formation and stability may be the key to unlocking robust Li₂S deposition and dissolution cycles. Hence, this strategy could mitigate common pitfalls like cathode passivation and capacity fading, which have limited long-term operational viability.
The fusion of experimental visualization with robust theoretical modeling provides a comprehensive framework that future researchers and engineers can exploit to rationally design electrode interfaces. Moving past empirical trial-and-error, the ability to predict and control molecular aggregation behavior and its effects on electronic properties opens new avenues for tuning battery chemistry on an atomic scale. Such sophistication could accelerate the sustainable deployment of lithium–sulfur batteries within electric vehicles, grid storage, and portable electronics.
Moreover, the study emphasizes the profound impact of molecular-level phenomena on macroscopic performance metrics such as charging speed and energy density. By showing that the electrochemical environment at the nanoscale directly modulates reaction kinetics and phase evolution, this research bridges a critical knowledge gap between fundamental science and technological application. It highlights the necessity for integrated approaches combining real-time imaging, theoretical insight, and materials engineering.
Looking ahead, the insights gained are poised to influence material selection, electrolyte formulation, and cell architecture design. Tailoring these elements to favor desirable HCIL characteristics could lead to batteries that not only charge rapidly and store vast amounts of energy but also maintain stability over many cycles. Furthermore, the foundational principles elucidated may inspire innovations beyond lithium–sulfur systems, potentially transforming a range of emerging battery chemistries where interface complexity rules.
In conclusion, this remarkable study marks a pivotal advance in understanding and harnessing the subtleties of interfacial charge transfer within lithium–sulfur batteries. By unraveling the competitive reactions shaped by concentration gradients and molecular aggregation, it charts a pathway toward high-performance batteries ready for real-world demands. As energy storage solutions continue to underpin the clean energy transition, such elegant fusion of fundamental science and engineering innovation will be indispensable for propelling next-generation technologies.

In recent years, forests have emerged as pivotal players in global climate mitigation efforts, representing one of the most promising nature-based climate solutions available today. These ecosystems sequester approximately 31% of anthropogenic carbon dioxide emissions annually, providing a critical buffer against the accelerating pace of climate change. However, the reliability of forest carbon credit systems—mechanisms designed to monetize and incentivize carbon sequestration efforts—has come under intense scrutiny. A groundbreaking study published in the journal Biological Diversity unveils deep-rooted methodological flaws that cast profound doubt on the environmental integrity of current carbon credit frameworks, signaling a crisis of confidence across global carbon markets.
The rigorous analysis, spearheaded by environmental scientists from Yangtze University and Beijing Normal University, meticulously dissects the complex architecture of forest carbon credit systems and identifies four principal structural weaknesses that collectively undermine their trustworthiness. Foremost among these is the use of subjective assessments of additionality, a core concept requiring that credited emissions reductions would not have occurred in the absence of the project. Present carbon credit models predominantly rely on static historical baselines to calculate additionality, yet only an alarming 6% of REDD+ credits—credits allocated under the United Nations’ Reducing Emissions from Deforestation and Forest Degradation program—provide robust empirical evidence to substantiate genuine additional carbon mitigation.
Beyond the critical challenge of additionality, the permanence of carbon sequestration—signifying the long-term retention of carbon stock in forest biomass—is grossly overestimated by current standards. This overestimation is particularly precarious in light of escalating ecological disturbances linked to climate change including wildfires, prolonged droughts, pestilence outbreaks, and inadvertent carbon leakage where forest degradation shifts to unmonitored regions. The failure to appropriately incorporate these growing risks into permanence calculations means that many credited projects likely exaggerate their true contribution to climate mitigation, presenting an illusory picture of impact.
The study further reveals that leakage accounting—the assessment and adjustment for project-driven emissions displacement—is critically underdeveloped. Prevailing methodologies apply a modest average leakage deduction of only 7%, a figure that starkly contrasts with empirical findings suggesting leakage rates ranging from 10% to a staggering 70%. Such systemic under-accounting inflates the perceived net climate benefits of these forest projects, enabling an artificially optimistic valuation of carbon credits within international markets and undermining carbon trading integrity.
Compounding these shortcomings are the conspicuous omissions of biophysical impacts such as albedo and evapotranspiration effects in carbon accounting. Forest ecosystems substantially influence Earth’s energy balance through their reflectance properties and water cycling functions. Neglecting these elements obscures the true net climate impact, as alterations in surface albedo can significantly offset the cooling benefits gained from carbon sequestration, thereby diluting the overall effectiveness of forest-based interventions in climate regulation.
The collective failure to address these intertwined issues has deep ramifications not only for the credibility of carbon markets but also for biodiversity conservation and community well-being, which are often marginalized in project implementation. Insufficient local community involvement and opaque benefit-sharing arrangements risk alienating indigenous stakeholders, raising social equity concerns, and jeopardizing the sustainability and durability of mitigation efforts.
In response to these multifaceted challenges, the research team advocates for a transformative overhaul of forest carbon credit systems through a data-driven, science-based, and integrative accounting framework. Central to this reform is the replacement of static baselines with dynamic monitoring systems that leverage high-frequency remote sensing technologies alongside advanced machine learning algorithms. This approach enables objective, continuous, and quantitative assessments of additionality, dramatically enhancing transparency and scientific rigor in credit issuance.
Addressing permanence requires the establishment of a comprehensive three-tier risk management architecture comprised of prevention, buffering, and insurance mechanisms. This tiered system proactively mitigates disturbances by integrating biodiversity conservation as a mandatory compliance criterion rather than considering it a supplemental benefit, thus embedding ecosystem resilience at the heart of carbon project governance.
Transparency and standardization are equally emphasized through the call for stringent Monitoring, Reporting, and Verification (MRV) protocols. The use of cutting-edge technologies such as Light Detection and Ranging (LiDAR) and environmental DNA (eDNA) is prescribed to ensure precise biomass and biodiversity assessments. Additionally, mandatory disclosure of datasets and verification methodologies aims to foster independent third-party audits, enhancing accountability and stakeholder confidence in carbon accounting practices.
Sociopolitical dimensions are also addressed, with the framework highlighting the critical necessity of formalized community governance structures and the institutionalization of Free, Prior, and Informed Consent (FPIC) procedures. These mandates ensure that forest-dependent communities retain decision-making power and equitable access to the socioeconomic benefits derived from carbon sequestration projects, thereby reinforcing local stewardship and long-term project viability.
While the introduction of these rigorous standards is expected to contract the overall volume of carbon credits issued—reflecting a more conservative and realistic accounting of mitigation gains—the resultant credits will embody higher integrity and trustworthiness. This qualitative transformation is paramount for forest carbon credits to evolve from contested commodities susceptible to skepticism into robust and reliable assets underpinning credible global climate governance.
The implications of this research are profound. By embedding scientific rigor and standardized risk management, forest carbon credits can realize their full potential as durable climate mitigation tools while simultaneously safeguarding biodiversity and respecting community rights. This paradigm shift promises to restore confidence among stakeholders, catalyze more effective climate finance mechanisms, and advance global efforts to stabilize the Earth’s climate system.
Ultimately, this work underscores a crucial message: nature-based climate solutions like forests must be governed by scientifically sound and socially just frameworks. Only through such commitment to transparency, accuracy, and inclusivity can these natural assets deliver genuine and lasting contributions to the fight against climate change.

In a groundbreaking advancement that bridges the gap between biological intelligence and artificial systems, researchers at Oregon State University have engineered a light-sensitive device that not only detects visual stimuli but also bio-mimics the brain’s ability to store and modulate memories dynamically. Drawing direct inspiration from the complex workings of human neural processes, this pioneering approach integrates sensing, memory, and signal processing into a single phototransistor, a feat poised to revolutionize the future of neuromorphic computing.
Traditional artificial intelligence hardware architectures typically bifurcate these essential functions—detection, memory retention, and processing—forcing data to shuttle between distinct components. This separation not only introduces latency but significantly amplifies energy consumption. The novel phototransistor developed by the OSU team disrupts this paradigm by embedding memory capabilities precisely where sensory inputs occur, vastly improving computational efficiency and speed.
Central to this device’s innovation is its ability to mimic the neurochemical processes governing memory strength and decay in the human brain. Rather than storing information with fixed permanence, the phototransistor utilizes trapped electrical charges generated by incident light to represent memories, which can then be pharmacologically tuned—via electrical gate voltages—to either reinforce or weaken these stored traces over time. This dynamic modulation reproduces the adaptive nature of biological synapses and opens unprecedented avenues for creating AI systems that can ‘forget’ as well as ‘remember,’ essential for real-time learning and adaptation.
Structurally, the device marries an oxide semiconductor acting as the electronic transistor channel with an organic photosensitive layer responsible for absorbing photons and generating charge carriers. The organic layer traps a subset of these carriers, creating a persistent local electric field even after illumination ceases. This trapped charge influences electron flow through the semiconductor channel, effectively encoding a memory of prior light exposure.
A key technical breakthrough lies in the device’s gate-tunable interface: by adjusting the voltage applied to the transistor’s gate terminal, researchers can manipulate the spatial positioning of trapped charges relative to the conduction channel at a nanoscopic level. This precise control modulates the strength of electrical interaction, allowing for programmable decay times of the optoelectronic memory—ranging from seconds to considerably longer durations. Such flexibility is vital for neuromorphic systems requiring adjustable time constants for processing temporal patterns.
The implications of this technology extend beyond simple visual sensing. By localizing both sensing and adaptive memory functions, the phototransistor can serve as a foundational building block for advanced vision systems capable of real-time data processing with exceptional energy efficiency. This novel hardware approach offers substantial improvements over conventional sensors, which often offload processing to centralized units, incurring latency and energy penalties.
Neuromorphic computing, a field striving to emulate the architecture and operational principles of the brain, stands to gain significantly from this development. The device’s capacity to embody synapse-like plasticity within a phototransistor embodies a leap toward systems that do not merely compute but adapt, learn, and optimize autonomously. Furthermore, the integration of these functionalities at the hardware level paves the way for compact, scalable AI platforms potentially transformative for robotics, autonomous vehicles, and sensory-rich IoT devices.
The research team acknowledges that the trapped charges’ mobility within the device’s photosensitive layer marks a fundamental departure from fixed-charge memory devices. By enabling charge repositioning in response to externally applied voltages, the phototransistor achieves an unprecedented degree of control over memory retention timescales—a property rarely realized in optoelectronic components designed for AI applications.
From an energy perspective, co-localizing sensing and computation reduces data transfer bottlenecks traditionally plaguing AI processors. This attribute directly addresses pressing challenges in AI hardware, where escalating computational demands often collide with limitations in battery life and thermal management. As a result, the novel phototransistor aligns with broader efforts to develop sustainable, high-performance AI technologies.
Conceived through a multidisciplinary collaboration spanning electrical engineering and physical sciences at Oregon State University, the device’s development also underscores the growing convergence of materials science with computational intelligence. By synergizing metal oxide semiconductors with organic tetracene compounds, the team harnessed complementary material properties—robust electron transport with efficient light absorption—to realize the device’s multifunctional capabilities.
The National Science Foundation’s support, alongside the efforts of researchers including Larry Cheng, Ahasan Ullah, Tasnim Sarker, Xueqiao Zhang, Andrew Ensinger, Lizhong Chen, Roshell Lamug, and Oksana Ostroverkhova, culminated in the publication of their findings in the esteemed journal Advanced Functional Materials. The study not only charts new territory in optoelectronics but also sets the stage for transformative innovation in neuromorphic computing hardware.
As artificial intelligence increasingly demands systems capable of real-world adaptability and resource efficiency, innovations like this gate-tunable neuro-phototransistor epitomize the direction forward. By drawing directly from the brain’s principles of memory modulation and energy-efficient computation, the OSU team’s technology heralds a new era where AI devices can perceive, process, and remember in ways that approximate human cognition more closely than ever before.

In a breakthrough that could reshape the future of sustainable materials and energy production, researchers at the University of Pittsburgh’s Swanson School of Engineering have unveiled a revolutionary method of producing high-quality graphite at significantly lower temperatures than those traditionally required. The pivotal discovery emerged unexpectedly in the laboratory of Professor Götz Veser, where ethane was pumped through molten metal heated to under 1,000 degrees Celsius. Contrary to expectations, the carbon byproduct that surfaced was not the usual mundane residue but a fluffy, high-grade graphite, a material that has become a cornerstone in advanced battery technologies.
Graphite, often hailed as “black gold,” particularly in contexts involving automotive and high-tech sectors, is indispensable for lithium-ion batteries that power electric vehicles and modern electronics. Currently, the industrial synthesis of such graphite is a notoriously energy-heavy process necessitating temperatures approaching 3,000 degrees Celsius. Moreover, the global supply chain is heavily dependent on China, which accounts for some 95 percent of battery-grade graphite production. This dependency presents significant challenges in energy efficiency, sustainability, and geopolitical autonomy.
The Pittsburgh team, led by Professor Veser and former PhD candidate Aime Laurent Twizerimana, along with Assistant Professor Mohammad Masnadi and PhD student Nader Sawtarie, recognized the urgent need for an energy-efficient and domestically viable alternative. Their research harnessed an underexplored catalytic method involving molten metals, a concept that traces its roots back nearly a century but remained largely unexploited in this context. Unlike conventional solid catalysts, molten metal catalysts offer a unique physical characteristic: their extreme density causes carbon to separate and float atop the molten medium, simplifying collection and preventing reactor clogging.
The process began as an effort to develop greener pathways for ethylene production by “cracking” ethane, a major component of natural gas abundant in Western Pennsylvania. Ethane cracking conventionally involves steam reforming, a technique plagued by continuous formation of carbon deposits that necessitate frequent shutdowns for maintenance. However, the molten metal catalysis technique demonstrated a cleaner and more efficient alternative, reducing energy input while producing valuable byproducts.
As Twizerimana delved deeper into his doctoral research, he noticed a curious variation in carbon morphology when different metals were employed. Some metals yielded a fluffy, distinct carbon arrangement rather than the dense deposits typically associated with ethane cracking. This observation spurred further analysis by Sawtarie, whose expertise in two-dimensional metals and graphene characterization was instrumental. Their collaboration revealed that this fluffy substance was, in fact, high-value graphite, matching or exceeding quality standards for battery applications.
This discovery not only offers a lower-temperature route for graphite synthesis but simultaneously generates hydrogen as a co-product. Hydrogen, widely recognized as a clean energy vector, complements the sustainability credentials of this novel process by providing an additional revenue stream and reducing reliance on fossil-fuel-based hydrogen production methods.
Revolutionizing a process that typically demands prolonged batch operations at scorching temperatures—often taking up to three weeks—this new method offers a continuous, scalable approach that could dramatically reduce carbon emissions and costs. While small-scale graphite production in the United States exists, it remains economically uncompetitive compared to Chinese imports. The Pittsburgh innovation aims to close this gap by delivering domestic, scalable, and cost-effective graphite synthesis.
Supported by the University of Pittsburgh’s Big Idea Center, which provides vital mentorship and resources for entrepreneurial ventures, the research team transitioned their laboratory success into a startup named Graphonos Materials. The startup’s disruptive technology captured the imagination of investors and judges alike, securing a $20,000 Aramco Innovator Prize at the prestigious Rice Business Plan Competition—an event often dubbed the “Super Bowl” of entrepreneurial pitch contests.
Beyond financial endorsements, these achievements underscore the market’s clear appetite for sustainable, low-cost graphite and the critical role such materials play in the clean energy transition. The team is currently advancing toward developing a fully integrated bench-scale system capable of producing kilograms of graphite per day. This milestone is a crucial stepping stone toward pilot-scale demonstrations and eventual commercialization, aligning with global efforts to localize critical materials supply chains and innovate energy-efficient manufacturing.
If realized at scale, the process promises dual environmental and economic benefits by transforming Western Pennsylvania’s ethane reserves into essential raw materials that undergird electric vehicles, renewable energy storage, and advanced electronics. It embodies a strategic pivot from traditional fossil fuel processing to value-added chemical production within a circular economy framework, contributing meaningfully to energy transition narratives.
As the demand for lithium-ion batteries accelerates worldwide, fueled by electrification policies and consumer preferences, the importance of sustainable graphite synthesis cannot be overstated. The Pittsburgh innovation leverages unique catalytic chemistry and materials science to disrupt entrenched production paradigms marked by extreme energy consumption and geopolitical bottlenecks.
Ultimately, this development is emblematic of how interdisciplinary research—melding chemical engineering, materials science, and entrepreneurship—can yield tangible solutions to pressing global challenges. By capturing the potential of molten metal catalysis, the Graphonos Materials team paves the way for greener, domestic production pathways that harmonize economic competitiveness with environmental stewardship.

The global shift toward net-zero emissions has thrust hydrogen into the spotlight as a promising energy vector capable of decarbonizing sectors traditionally reliant on fossil fuels. Yet, as hydrogen technologies surge from concept to commercial reality, a critical question has emerged: can the insurance industry keep pace with the novel risks intrinsic to these systems? A compelling new article published in Engineering unveils the stark challenge facing insurers and innovators alike. It argues that the nascent nature of hydrogen processes and infrastructures presents a complex risk landscape that current insurance frameworks are ill-equipped to navigate, potentially impeding large-scale deployment needed to meet climate goals.
Central to the discourse is the intricate, multifaceted nature of hydrogen technologies, encompassing production, storage, transport, and utilization systems. Unlike mature renewable technologies such as wind and solar, hydrogen operations are fraught with unique hazards—including extreme flammability, material embrittlement due to hydrogen exposure, and elusive leakage risks—that conventional insurance models have yet to thoroughly address. This gap in risk assessment and management means that financial security mechanisms crucial for investment confidence remain underdeveloped, posing a significant barrier to scalable hydrogen adoption.
The article elucidates that hydrogen’s promise as a clean energy carrier depends not only on decarbonized production but also on scaling the entire value chain rapidly and reliably. However, these pioneering engineering systems entail a gamut of evolving operational risks. These span from property damages and equipment failures to worker safety concerns heightened by hydrogen’s explosive potential. Cybersecurity risks also arise given the increasing digitalization of energy assets, while governance challenges manifest through liability exposures of company directors as projects push technical boundaries. Furthermore, these uncertainties extend into supply chain fragility and performance shortfalls during system ramp-up phases, compounding insurers’ difficulties in crafting comprehensive coverage.
Drawing a parallel to renewable energy insurance markets, the authors observe how wind and solar have benefited from years of data accumulation, modeling refinement, and standardization efforts that underpin sophisticated insurance offerings. This data-driven maturation enables parametric insurance and warranties that safeguard against specific performance metrics and supply chain disruptions. Yet, hydrogen insurance remains embryonic, characterized by cautious underwriting and limited products chiefly targeted at niche applications rather than broad industrial deployment. This immaturity translates to cost premiums and coverage limitations that stall financing and project momentum.
To transcend these hurdles, the article emphasizes the critical need for structured data collection and robust risk characterization specific to hydrogen processes. Without granular operational insights and validated risk models, insurers default to conservative stances that restrict underwriting appetite. The authors champion innovative insurance instruments, notably parametric policies calibrated to predefined risk triggers, and performance warranties that hedge against technology underperformance. These solutions can lower uncertainty for investors and catalyze capital flow, but their success hinges on collaborative data-sharing and transparent risk communication between all stakeholders.
Importantly, the narrative draws attention to a strategic opportunity for insurers. Engagement with hydrogen not only mitigates climate-related portfolio risks but also opens access to a burgeoning industrial market driven by global net-zero ambitions. Nonetheless, disconnects persist between technology developers’ needs and insurers’ capabilities, underscoring the urgency for proactive, multi-stakeholder dialogue. Fostering early-stage collaboration among engineers, academia, private sector, and insurance providers is pivotal to co-design risk assessment methodologies, standardize certification regimes, and ultimately align insurance solutions with engineering innovation trails.
Academia is positioned as a critical catalyst in this ecosystem. Researchers can bridge the gap by aggregating operational data, refining risk models via simulations and real-world studies, and facilitating standardization efforts that underpin insurer confidence. Such integrative efforts advance both scientific understanding and commercial viability. Aligning insurance mechanisms with engineering innovation timelines ensures risk management is embedded from technology readiness level milestones onward, thus streamlining the pathway from pilot projects to full-scale industrial rollouts.
The article also highlights the financial repercussions of currently inadequate insurance coverage. High premiums and coverage gaps retard investment flows and engender hesitancy among financiers wary of unquantified risks. As hydrogen projects are capital-intensive with long development horizons, risk mitigation via comprehensive insurance is non-negotiable for unlocking broader investor appetite. Hence, the advancement of hydrogen insurance products is not merely a financial instrument but a keystone for sustainable market adoption and technological acceleration.
Furthermore, the article delves into technical challenges such as hydrogen’s propensity to induce embrittlement in metals, which degrades structural integrity over time and raises maintenance costs. Insurance models must incorporate such materials science insights to accurately price and cover long-term durability risks. Leakage detection and mitigation technologies also play a vital role in controlling operational hazards, with insurance frameworks incentivizing advancements in sensor deployment and safety protocols. These technological synergies between engineering and insurance amplify resilience and facilitate risk reduction.
In conclusion, the article contends that unlocking hydrogen’s potential as a linchpin of a net-zero future demands a paradigm shift in insurance thinking coupled with systemic collaboration. By gathering rigorous data, designing bespoke risk instruments, and fostering cross-sector partnerships, the insurance market can evolve to support hydrogen innovation robustly. This evolution will serve as the linchpin of investor confidence, enabling swift scale-up while safeguarding public and environmental safety. Without such advancements, the hydrogen economy risks stalling, imperiling global decarbonization trajectories.
The implications extend beyond risk transfer to the very architecture of hydrogen energy systems. Insurance integration informs engineering decisions, safety standards, and policy frameworks, creating a virtuous cycle that harmonizes technical innovation with financial viability. The authors’ clarion call is clear: accelerating the hydrogen transition mandates bridging the gap between emergent technology risks and insurance market readiness. Achieving this nexus will be transformative—not only for hydrogen but for the broader energy transition imperative writ large.

The post Scientists turn ordinary water into a powerful energy storage material appeared first on Knowridge Science Report.
Thousands of electric vehicles in Waymo’s autonomous robotaxi fleet may eventually give up their used batteries for a very different purpose—contributing up to hundreds of megawatt-hours of stationary energy storage to local power grids.
That prospect comes from a “strategic supply agreement” announced by Waymo and B2U Storage Solutions on June 4. B2U has been repurposing thousands of used batteries from various electric vehicles by installing them in large stationary energy storage projects. Such energy storage facilities can capture excess renewable energy during low demand periods and release such energy when local power grids are experiencing peak demand periods.
“Our business is getting the full residual value out of electric vehicle batteries after they're no longer suitable for automotive use,” Freeman Hall, CEO of B2U Storage Solution, told Ars. “Waymo puts a lot of miles on EVs and their model is expanding rapidly, and so we're just very pleased and honored to be able to work with them.”
