If you want to be as green as possible with today's technology the holy grail is probably LPG derived from nuclear reactor powered atmospheric carbon capture. Existing fueling infrastructure is used, low vehicle emissions since it's not a liquid when injected, retrofit is possible for every vehicle on the road today with existing and proven technology, compact fuel storage, familiarity in much of the world, the works. It's great.
- Retric 4y agoElectrified highways (over head or in road) is vastly more efficient and covers the vast majority of truck pollution. Ex: https://www.volkswagenag.com/en/news/stories/2019/07/electrified-highway.html https://www.volkswagenag.com/en/news/stories/2019/07/electri... or https://www.greencarreports.com/news/1127520_world-first-in-road-charging-test-for-trucks-successful-highway-speeds-next https://www.greencarreports.com/news/1127520_world-first-in-... After that using bio or synthetic fuels, batteries, hydrogen etc are more reasonable because they need to supply vastly less energy per trip.
- abakker 4y agoI don't think this is true if you factor in the Total carbon from the process of actually electrifying the roads. Its a ton of cabling made out of a ton of metal that needs to be mined.
- Retric 4y agoIn comparison to building 5 or more times as many nuclear reactors, vastly more of whatever fuel creating facility you want etc it’s a clear win.
- orangepurple 4y agoI don't think it's a clear win. Because the scale of either initiative seems to be massive it warrants further study. Regardless, electrified freeways are a very interesting concept and I have never seen them anywhere yet.
