For the same energy inputs you could travel 3 times as far for a 5th the CO2 emissions and well under half the cost in an electric truck.

ChatGPT & DALL-E generated panoramic image contrasting a highly wasteful process with a very efficient process is ready. It visually splits the scene to show the stark differences in environmental and resource management

We arrived at two summary tables which highlighted the comparisons. This first was the energy, CO2, and cost workup for creation of methanol. That assessment, which was incredibly generous to Carbon Engineering’s process and ungenerous to electric vehicles, found at best its fuel would be 25x the cost and 35x the CO2 emissions of just using an electric vehicle with the same energy.

How much diesel would be created by this process? Once again, that’s easy. The 272 kg of carbon will combine with roughly 46 kg of hydrogen to create 318 kg of diesel. Hmmm, that’s a lot less than the 730 kg of methanol that would be created. Cost and CO2 comparisons of powering semi trucks by Michael Barnard, Chief Strategist, TFIE Strategy Inc

Two fewer hydrogen in the ratio means less electricity to produce the hydrogen. Let’s assume yet again that generously a variant of the Greyrock process uses the same energy to make kerosene. But what about CO2? After all, this is supposed to be carbon emissions reduction technology. So far, it’s not working, but maybe in alternative jet fuels it actually has a value proposition?
