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

As predicted, Carbon Engineering's air-carbon capture solution to be used by oil majors such as Occidental for enhanced oil recovery to no climate benefit

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

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

This article will look at some of the suggested solutions, and look at a few billionaires and how they are actually spending their money, and make some judgments about the experts and their opinions

Pete Buttigieg's climate action plan is not nearly as strong as Warren's, and the lack of funding puts it close to the level of Biden's at the bottom of the heap. The major saving grace is the price on carbon

The most popular CleanTechnica stories of October were led by Polestar and Mazda. Seriously. No offense to Polestar or Mazda (okay, some offense to Polestar and Mazda), but I wouldn't have seen that coming a mile away. Does this show a great thirst for more EV news beyond Tesla and more serious EV entries? Possibly. Or it was just some lucky timing and catchy headlines. Or all of the above. In any case, that's where things landed in October. Tesla still dominated the top 20, with 15 out of 20 stories, but it was an interesting phenomenon to see the company almost pushed out of the top

Carbon capture has a powerful allure. The Earth is overheating because there is too much carbon dioxide in the atmosphere. So why not suck out the excess, then store it in holes deep underground -- there are thousands upon thousands of old oil and gas wells just waiting for some useful purpose to come along -- or use it to make biofuel, fertilizer, medicine, and biodegradable plastics? It sounds like the ideal solution to a problem that affects us all

The following are the climate change solutions or approaches that I see from my investigations and discussions as gaining consensus and consilience on their viabiilty. It's not the how, but the what

We have to do better. And we can't let the fossil fuel industry continue to get in the way of progress, as they clearly did on Friday at the Vancouver, BC climate solutions conference

Biden's climate plan is good on transportation and foreign policy, land use is adequate, but won't get out the Democratic base or draw many Independents. It's a plan to not lose votes, not a plan to get votes, and it's not a sufficient plan for climate action

Yang’s single largest dollar expenditure, 62% of his US$4.9 trillion budget, would only impact 2% to 5% of US energy consumption. And his investments on geoengineering, fusion, and thorium nuclear generation are purely wasted expenditures
