"In the startup’s carbon dioxide removal system, sunlight will activate the chemical, and the acidic protons will flow into a tank of seawater. That will cause carbon dioxide gas to bubble out of the water, something like it does in a highly carbonated soda. The system captures the carbon dioxide for disposal and transfers the protons back to the photoacid. The seawater is returned to the ocean."
"San Jose, California-based Anthro’s differentiator is that its electrolyte is a drop-in technology that wouldn’t require battery manufacturers to make any changes to their process, according to Mackanic. Despite these advantages, the startup’s current electrolyte production costs are about twice that of producing conventional liquid electrolytes, due in part to the cost of its materials. He expects to be able to get that down to a 10% to 20% premium at commercial scale."
"In December 2023, notably, the company secured a construction permit from the Nuclear Regulatory Commission (NRC) to build the non-power demonstration reactor in Tennessee. The approval marks the NRC’s first green light for the construction of a non-water-cooled reactor in more than 50 years. Kairos, however, must first secure a separate NRC operating license before it can begin operating the Hermes demonstration to comply with the regulatory body’s two-step, 10 CFR Part 50 licensing process."
LanzaJet will make 10 million gallons of sustainable jet fuel annually.
"As huge numbers of solar panels are deployed now, the future waste challenge also keeps growing. By the end of the decade, one estimate found that the number of solar panels due to be retired would cover 3,000 football fields. By 2050, the U.S. could produce two million metric tons of solar panel waste each year."
"Fusion energy is the process that powers the sun and other stars, and experts have been trying for decades to master it on Earth. It is achieved when two atoms that usually repel are forced to fuse together. It’s the opposite of nuclear fission — the type widely used today — which relies on splitting atoms."
"In the end, the better question to ask is not whether humanity should collect deep-sea metals, but rather how. Before claiming that the cost of collecting nodules from the ocean floor is too high, researchers, activists, regulators, and companies should explore the degree to which operators can reduce impacts and define what obligations to hold industry accountable to. As such, calling for immediate moratoriums on deep-sea mining is not only premature, but a circumvention of constructive dialogue and negotiation."
"Lilac says its technology is much faster, taking a matter of hours from the time of extraction, while preserving water levels. Its method deploys reusable ceramic 'beads' that attach to lithium atoms to separate them from the brine. Snydacker says the company has spent more than 500,000 hours testing the technology on more than 70 brine samples around the world."
"With the NRC’s approval of GNF’s fuel fabrication license amendment, the company’s manufacturing facility in Wilmington, N.C., becomes the first commercial facility in the United States to hold a license to fabricate fuel containing up to 8 percent U-235, according to GE Vernova. The NRC has issued a certificate of compliance allowing GNF to ship fuel bundles using the company’s RAJ-II shipping container. The agency has also approved licensing topical reports for advanced nuclear methods that will permit GNF to analyze fuel with enrichments above the 5 percent U-235 limit for conventional low-enriched uranium (LEU) fuel."
"For years, scientists have been developing small modular reactors (SMR), which are scaled-down power plants that can provide power in situ and thereby dramatically reduce companies' dependence on the grid."
