BY: ANCA GURZU To avoid the most catastrophic impacts of climate change—and achieve a net-zero world—we need to not only reduce our emissions, but also remove residual carbon dioxide (CO2) from the air. That part is…
Editor’s Note:In supporting “all of the above” clean energy sources, nuclear has a place. The Nuclear Action Team at CCL has some very impressive voices, and nuclear generation costs (including the costs of safety and…
There’s enough uranium dissolved in the oceans to power the world for 100,000 years and more. The good news is that there’s a known chemical reaction and method for capturing it, albeit at a cost ($200/kg) about twice that of getting U-238 from mining uranium ore on land. This post summarizes four recent announcements.
New fusion announcements and next-generation fission reactors appear to be viable sooner than expected. (1) See “Microsoft Bets That Fusion Power Is Closer Than Many Think” and (2) Andreesen-Horowitz leads Series B for Radiant Industries (air-cooled, 1-megawatt nuclear reactors, the size of a shipping container). See also Aalo. The promise: non-interruptible, clean power at 3 cents / kwh.
Note: We at CCL are working hard to speed the transition to clean energy. Getting to NET ZERO (and even to negative emissions to move back from the brink) requires removing CO2 from the air. Here are two projects to keep an eye on.
[Editor: When private companies bet on tech that not supposed to be ready until the 30’s (or 40’s), I pay attention!] Scientists have been dreaming about nuclear fusion for decades. Microsoft thinks the technology is…
Here is a DAC project under contruction with service date of 2025 and scaling to remove up to a million tons/year of CO2 and store it underground. Subsidies from the IRA help, and Occidental plans…
This is an excellent explanation of the technologies (capturing CO2 from flue gasses and “direct air capture”), the policy arguments and the incentives (with the IRA subsidies). Very clear, nicely summarized.

We’ve already done a fair amount of damage to our ecosystem. And even with new, clean sources of energy, we’ll need to clean up the mess we’ve already made. That’s where carbon removal comes into play. See these three 3-minute videos of startups tackling the issue.
Floating turbine swaps out the single large pole for four thinner ones angled in a pyramid shape. This distributes the weight of the turbine’s pieces, allowing the structure to be lighter. Constructed in a shipyard, its towed into place.
