Canadian-based critical minerals company E3 Lithium has commissioned Phase 2 of its Clearwater Project Demonstration Facility in Alberta and confirmed lithium concentrations of 75.8 milligrams per liter in brine produced during ongoing reservoir testing.

The company said the latest results support the consistency of lithium-bearing brine chemistry across the Clearwater Project and the broader Bashaw District, a key factor as it advances plans for commercial lithium production.

The demonstration facility is currently being used to test reservoir performance over an extended period. Brine is pumped from a production well and immediately reinjected into a separate injection well, allowing engineers to evaluate flow behavior and reservoir response under operating conditions.

According to the Alberta-based company, the facility achieved stable production and injection through the well pair. During early operations, an electrical submersible pump maintained the targeted flow rate of 1,400 cubic meters per day.

Brine tests confirm consistency

The company regularly collected brine samples during operations and sent them to an independent third-party laboratory for analysis. Results confirmed lithium concentrations of 75.8 mg/L, matching expectations for the resource.

E3 said the reservoir data generated through the testing campaign will be used to update its reservoir development plan and support a feasibility study for the Clearwater Project.

The next stage of operations will focus on analyzing the relationship between brine and natural gas within the reservoir. The information is expected to support the design of the front end of a future commercial processing plant.

The demonstration facility forms part of E3’s broader effort to reduce technical risks before moving toward large-scale lithium production.

“With Phase 2 operations underway, E3 has begun a series of project-scale de-risking activities for the Clearwater Project,” said Chris Doornbos, CEO and chair of E3 Lithium.

The company added that the current campaign has already processed more brine through the two new wells than all of its previous testing programs combined.

Scaling toward production

Lithium demand continues to grow as automakers and battery manufacturers seek additional supplies of the metal used in electric vehicle batteries and energy storage systems.

For E3, the demonstration facility serves as a bridge between laboratory-scale testing and commercial deployment. Data collected from reservoir operations, brine chemistry studies, and future process testing will be used to refine engineering designs and operating plans.

“We have already moved more brine through these two wells than E3 has handled through all its previous testing combined, and we expect to continue to operate the pump as needed over the coming 24 months,” Doornbos said.

He added that confirmation of reservoir performance and lithium grades at the new wells strengthens confidence in the predictability of the resource.

The company plans to continue operating the demonstration facility while advancing front-end engineering design work and completing a feasibility study for the project. The resulting data will help determine the design of a future commercial facility and support decisions related to full-scale development.

China has launched a new research laboratory dedicated to photonic computing, a technology that uses light instead of electricity to process information and could help address the growing power demands of artificial intelligence and advanced computing.

The Shanghai Key Laboratory of Integrated Photonic Computing Chips and Systems was officially launched this week in Shanghai. According to local reports, it is China’s first industry-academia platform focused specifically on photonic computing research and development.

The facility is based at Shanghai Jiao Tong University and will bring together researchers and industry partners to develop photonic chips, optical components, computing architectures, and software systems needed to support the technology.

The launch comes as countries and technology companies race to secure enough computing power to train and run increasingly sophisticated AI models. As data centers consume more electricity, researchers are looking beyond traditional semiconductor designs for alternatives that can deliver higher performance with lower energy use.

Light over electrons

Unlike conventional chips that move data using electrons through silicon circuits, photonic chips rely on photons, or particles of light, to transmit and process information.

Because photons travel faster than electrons and generate significantly less heat, photonic systems could potentially offer major gains in speed, bandwidth, and energy efficiency. Researchers believe such systems may help overcome some of the physical limitations facing traditional semiconductor technologies.

Zou Weiwen, director of the new laboratory and a professor at Shanghai Jiao Tong University, highlighted the technology’s potential, describing it as “an important pathway for achieving breakthroughs in computing power, offering advantages in bandwidth, latency, and energy efficiency.”

The new laboratory will focus on several areas, including photonic chip architectures, silicon-photonics integration, optical devices, supporting algorithms, and commercial applications.

China has increasingly identified photonic computing as a strategic technology as it seeks alternatives to advanced semiconductor technologies that remain difficult to access because of export restrictions and supply chain challenges.

Building local ecosystem

Shanghai authorities said they have supported research into photonic computing through multiple science and technology programs while also investing in innovation platforms and industrial development.

The push toward photonic computing comes as researchers worldwide explore alternatives to conventional chip designs that are approaching physical and thermal limits. Supporters of the technology argue that light-based processors could help reduce the massive energy consumption associated with AI data centers while enabling faster data movement across computing systems.

The laboratory is a joint initiative between Shanghai Jiao Tong University and Lightelligence, a Shanghai-based startup specializing in photonic computing technologies.

Lightelligence has previously claimed to be the first company to achieve large-scale deployment of hybrid optical-electronic computing systems. The company has emerged as one of China’s leading players in the photonic computing sector.

Despite growing interest in the technology, significant technical hurdles remain before photonic computing can be deployed at scale.

Zou noted that one major challenge is the lack of a mature software and algorithm ecosystem capable of fully utilizing photonic hardware. Researchers must also address fundamental scientific and engineering problems before the technology can achieve its theoretical performance advantages.

Still, the launch of the new laboratory signals China’s intention to accelerate research into light-based computing as demand for high-performance computing and AI infrastructure continues to grow worldwide.
