  • I’m not so concerned about the carbon footprint of battery manufacturing as I am with the broader externalities associated with the battery lifecycle. This article is a few years old, but it provides a relevant, sobering assessment of the problem. Hydrogen powered vehicles make sense now because they avoid that problem. They’re also a better choice for anyone whose driving needs would outpace overnight charging of a BEV at home (or anyone with a living situation that precludes it). The current policy of exclusively transitioning the fleet to BEVs is at best a kludge for bad energy policy.



  • You’re not really describing a problem with hydrogen powered vehicles. You’re describing the problem with the way we’ve been trying to generate power free of greenhouse gas emissions. As long as the policy makers keep myopically insisting that we only do it with certain renewables, it doesn’t matter if battery electric vehicles are actually more efficient or not. So, on balance, the relative inefficiency of a hydrogen powered fleet is more than made up for by avoiding a massive stream of battery waste that everyone seems to be ignoring.








  • It seems like there is a problem with whatever Lemmy UI you’re using. The post is formatted fine in the default Lemmy UI with the hashtags showing as normal hyperlinks: image

    I’m aware that hashtags don’t have a function in Lemmy, but the post is originally from Mastodon. Furthermore, in spoken English sometimes people will add “hashtag” as a prefix to words and phrases for emphasis. That said, @dessalines@lemmy.ml et al should definitely add hashtag functionality to Lemmy. It could be useful for post flair, for example, besides compatibility with the rest of the fediverse.

    Sorry if you don’t like cross posting. I think it’s a nice feature that helps more people see posts and find communities. It also helps me interact with commenters when I make a post originally to Pixelfed or Mastodon.
