Claims by the Coalition and One Nation that abandoning a net zero climate target would bring down power prices are contradicted in a new CSIRO report on the costs of generating electricity.
Generation costs will probably rise after 2030 regardless of Australia’s policy on net zero, according to the CSIRO’s annual GenCost report, but prices should then stabilise at levels below recent price spikes.

The First Nuclear-Powered Satellite is Now in Orbit
Tuesday marked a new chapter in the quest for novel power systems for spacecraft, with the launch of the world’s first satellite equipped with a commercial betavoltaic nuclear power system.
The City Labs Betavoltaic Orbital High-Reliability (BOHR) satellite was carried to space on board a SpaceX Falcon 9 rocket, and in the coming weeks will begin tests to determine whether miniature nuclear batteries can reliably generate electricity in space.
Designed primarily as a proof of concept, the first BOHR satellite will rely on conventional solar panels for its primary power system. However, the first-of-its-kind spacecraft also carries the company’s proprietary “NanoTritium” betavoltaic power source, which, according to the company, uses beta particles emitted during the radioactive decay of tritium that are converted into electricity.
In a statement, Peter Cabauy, CEO of City Labs, called this week’s launch “a historic step for commercial nuclear power in space,” adding that the BOHER satellite “demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment.”
“This capability enables persistent, always-on payload operations that are not constrained by sunlight or battery life,” Cabauy added.
Harnessing the Power of Beta Radiation
The innovative satellite was carried to space earlier this week as part of the recent SpaceX Transporter-17 mission.
“On Tuesday, July 7 at 12:12 a.m. PT, Falcon 9 launched the Transporter-17 mission to low-Earth orbit from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California,” read an update that appeared at the SpaceX website announcing the successful launch that carried the City Labs BOHR satellite to space.
“Transporter-17 was a dedicated smallsat rideshare mission,” SpaceX’s update earlier this week added. “There were 81 payloads on this flight, including cubesats, microsats, hosted payloads, and orbital transfer vehicles carrying eight of those payloads to be deployed at a later time.”
Following the satellite’s successful delivery to orbit, its power systems will begin testing the feasibility of beta radiation as a primary driver to produce electricity. In the past, radioisotope thermoelectric generators have been used to propel landmark space missions, such as Voyager 1 and Voyager 2. By contrast, BOHR’s beta radiation system does not rely on heat generated by radioactive decay, which allows for a compact power source that, if all goes according to plan, could one day be deployed in future missions to support spacecraft operating in environments where sunlight is limited. Such applications include the permanently shadowed craters on the Moon and future missions into the outer solar system.
Primarily, City Labs says a tritium-based system is also more beneficial than traditional nuclear fuels like plutonium since it emits relatively low-energy radiation. This, the company says, makes it easier to shield and safer to handle during spacecraft assembly and launch.
Challenges Ahead
The technology does face significant hurdles, however. One involves the fact that tritium is presently still one of the world’s rarest—and most expensive—radioactive materials. Right now, with only around 20 kilograms produced annually throughout the world, the limited quantity and exorbitant costs (current prices reach tens of thousands of dollars per gram) make large-scale adoption anytime in the near term a significant challenge.
There are also regulatory considerations, as noted in a news article released this week by the American Nuclear Society (ANS) following the launch. “In 2019, National Security Presidential Memorandum – 20 (NSPM-20) laid out updates to the process for launching spacecraft containing nuclear systems,” the article states.
“Now the Department of Transportation, which includes the Federal Aviation Administration (FAA), directs the coordination of various agencies to review the safety analysis for missions with nuclear components,” the ANS news brief added, noting that the FAA updated its launch regulations in 2020.
Despite the existence of a few hurdles and other considerations, the mission nonetheless marks an important milestone in the development of next-generation spacecraft power systems. If successful, BOHR could demonstrate that compact betavoltaic power sources are a viable complement to solar energy, opening new possibilities for long-duration missions in some of the darkest and most remote regions of the solar system.
The proliferation of nuclear power in space got a little more real Tuesday with the launch of a small satellite developed by a Florida-based company specializing in nuclear micro-power technology.
The satellite from Miami-based City Labs is named BOHR, short for Betavoltaic Orbital High-Reliability, and it launched on a SpaceX rideshare mission Tuesday alongside 80 other payloads. SpaceX's Falcon 9 rocket released the BOHR satellite into an orbit between 350 and 400 miles (nearly 600 km) in altitude.

Last week, just before the US started its break for the July Fourth holiday, the Nuclear Regulatory Commission (NRC) proposed a new rule that would change how it regulated exposure to radiation. The Trump administration has been pushing to restart construction of nuclear power plants in the US, and many pro-nuclear advocates have been complaining about the US's existing regulations, portraying them as the main barrier to the flourishing of the industry. So, it had seemed likely that major revisions were coming.
Instead, the NRC's proposed new rules endorse the science behind its current rules and suggest that any problems are largely in the vagueness of the terminology that it has been using. So, instead, it's endorsing standards that are meant to accomplish the same thing, but avoid using some of the language it had relied on. Probably the clearest indication of the evolutionary change at play is that the NRC estimates the changing rules will save industry—not just power, but also medical and research applications—only about $9.5 million a year.
LNT and ALARA
There are two technical abbreviations at the center of US nuclear regulations. The first is LNT, which stands for "linear non-threshold." It's in reference to the issue of whether there's any level of radiation that is so low that it no longer produces harmful biological effects—the "threshold" in LNT. The "non-threshold" implies that it doesn't, and that's in keeping with biology, which has demonstrated that even single particles or photons of radiation can damage DNA and that the mechanisms cells have for repairing that damage are inherently error-prone. The "linear" in LNT simply describes how the impact of radiation scales directly with the dose.
Extension comes as government encourages first nuclear power projects in a generation to meet UK’s growing need for electricity
Britain’s most recently completed nuclear power plant will continue generating electricity until 2055 after the government granted the power plant a 20-year life extension.
Sizewell B in Suffolk was due to shut down within the next decade, but under a deal with the government its lifetime will be extended to 60 years to help meet the UK’s growing demand for low-carbon electricity.
The economic shock of the closure of the Strait of Hormuz has sparked calls to abandon fossil fuels faster. But that's the wrong lesson, says Richard Lyon – and Net Zero obsessed Britain will learn this the hard way.
Just over a year ago, the Trump Administration issued an executive order meant to accelerate the development of nuclear power in the US. While an entire startup ecosystem has developed around the use of different—and typically smaller—reactor designs, only one of them has been fully licensed so far, and there are no plans to actually build any instances of that design.
The executive order directed the Department of Energy to have three different reactor designs reach criticality in a bit over a year. On Thursday, a startup called Antares announced that a test reactor it had placed at the Idaho National Laboratory had reached criticality, making it the first new design to cross this threshold. Criticality means that the nuclear reactions inside the hardware had become self sustaining; it does not mean the reactor had started to generate power.
Antares is one of a number of companies that is basing its design on a new fuel system called TRISO that takes some of the complexity and safety out of the reactor design and places them in the fuel design. The fuel design is based on tiny pellets with a uranium oxide core. The pellets are surrounded by several layers of carbon that can moderate the energy of both the neutrons and lighter nuclei that are released by fission reactions. All of that is encased in a hard ceramic shell that's designed to withstand the highest temperatures that can be produced by the encased uranium.
Numerous UFO sightings, particularly near nuclear sites, raise questions about their purpose. Some suggest these crafts harvest energy from power stations, connecting spiritual dimensions with our physical realm. Historical data supports a correlation between UFOs and nuclear facilities, leading to speculation about their energy needs and where they come from.
