Researching air-carbon capture for use post-2050 remains a very good means of establishing the intellectual capital and basic technologies for when it makes sense to use them. But attempts to commercialize them today are premature

If Carbon Engineering is making e-diesel, driving the same distance in a freight truck would cost at least 6.5 times as much and have 16 times the CO2 emissions as just using electricity in a Tesla Semi

Carbon Engineering will produce transportation fuels that cost 18-25 times more and have 22-35 the CO2e emissions as just using electricity in an

Carbon Engineering is planning to build high-cost and comparatively high-emission transportation fuels by combining their expensive CO2 with hydrogen which they will get via expensive electrolysis

Air carbon capture, especially as Carbon Engineering is doing it, is a fig leaf for the fossil fuel industry

Carbon Engineering's solution is only useful in tapped-out oil wells and as greenwashing for fossil fuel companies

Carbon Engineering's solution would require 2-kilometer long, 20 meter high walls of noisy fans to capture 4 orders of magnitude less carbon than would be useful.

Carbon Engineering's solution is a natural gas hog that produces a half ton of new CO2 for each ton captured from the air.

To scale to an inadequate million tons of CO2 a year, the company would need 2,000 two-meter fans blowing air into contactors in an array 20 meters high, 8 meters thick, and two kilometers long

Long-haul aviation is a hard global warming nut to crack, and assessing methanol as a potential nutcracker shows why

People like Bill Gates throw away their money on the wrong investments: small nuclear, air carbon capture, and solar geoengineering. Gates and others should listen to Mark Z. Jacobson more, and Vaclav Smil less

Carbon sequestration does not have to cost any more than nations have already spend on fighting the coronavirus. New polls show climate change is high on the list of concerns for voters. So why is the US not taking a leading role? George Carlin has the answer.

This section is meant as a primer to the world of climate change and renewable energy. CleanTechnica has posted over 40,000 articles since its inception in 2008, however, reading all of them would take months, so the following is a distillation of the key pieces of the puzzle

The first article covered the first two points, showing that tying this to, for example, a single reasonably sized cement plant would require roughly 4,000 times the space, and that decoupling energy creation from demand would provide substantially more flexibility and higher value. Now we'll step through the remaining three problems

Bill Gates seems to love to invest in things that aren’t going to make much of a difference to climate change but that are good for the fossil fuel industry. The latest is Heliogen, a company which uses machine learning to make solar ovens hotter and more reliable
