That's really the problem in broad strokes. Getting consumers off gas is all well and good, but even in the worst cases for some of the longest commutes I know of and people who love long road trips, that's probably at most 90 minutes of daily engine usage that's eliminated. That's just... fucking nothing compared to stuff like construction equipment and LTL trucks, that are both far larger in sheer engine size and carbon emissions, and run upwards from 12 hours a day. Bigger more consistently operating vehicles are better targets to actually get carbon emissions down, and they're far harder to electrify, as we're seeing.
Nobody wants to talk about the fact that just shipping less unnecessary shit would do tremendously more for the environment than the greenest tech available, in the same way it initially made such big waves during the early days of the pandemic. Like, imagine how much CO2 would be saved if we just shut down essential oils tomorrow. The whole thing, the entire industry, because it's flagrantly bullshit. I'm not even saying it's an industry that produces a ton of CO2, I'm just saying it's an industry that produces CO2 while accomplishing nothing useful.
- thijson 3y agoThere's work being done on alternative fuels: https://www.bbc.com/news/business-54511743 https://www.bbc.com/news/business-54511743 Ammonia has no carbon atoms in it, just hydrogen and nitrogen which are abundant. It can be synthesized using the Haber process, and electrolysis, all energy inputs can be green. On the con side, its energy density isn't as good as fuel oil (half as energy dense). It needs to be compressed to stay liquid (like LNG). Also it's a poisonous gas. Could be corrosive to certain metals too. Maybe those issues can be worked around though.
