I haven't heard about this. Can you elaborate on what happened?
Kari Byron, formerly of MythBusters fame, recently put out an ad for Shell. I believe she's also committed to a 3 year "docuseries" for them. See here for a thread on Lemmy.world with a link to the video
I can't find the specific video but here is the first video in her series: https://piped.video/watch?v=hghIckc7nrY
She says that the hydrogen is sourced using water and renewables but it's highly sus that Shell (or BP; I can't remember) was sponsoring the series.
Shell does that all the time. Among the oil companies, they seem to be the biggest advocates for hydrogen.
They 100% know that electrolysis methods won't be economically viable. The path through hydrogen goes through traditional hydrocarbon sources.
One maybe possibly exception is the recent finds of underground hydrogen sources. Still unclear if that's going to be economically viable. But even if it is, we would just add it to the list of decarbonized energy sources. We're not short of solutions; we're short of political capital to implement them.
I would argue against that any day. Electrolysers are viable, they are just not the current state of the industry because dirt cheap solar and wind weren't around in previous decades.
It's the storage that might not be viable in most countries (because only some have geology that allows for underground gas storage). Producing hydrogen from water at 95% efficiency is doable with today's tools, if you have somewhere to put it.
Electrolysis is a great idea for local generation using excess domestic solar capacity. They are shit as a centralized fuel generation mechanism.
The biggest issue is that batteries are just better than hydrogen electrolysis for local domestic storage.
We don't have a lack of other possibilities for using excess solar/wind. Heating up rocks can work.
Fucking. Mood. People need to stop relying on fucking governments; I can think if like five that aren't hardcore invested in the end of the world (the largest of those being, like, Cuba, which still uses oil for everything because its all they can get-the others are even more marginal). We need more guerilla infrastructure or syndicalist infrastructure. Especially energy.
Well, if you make a single hydrogen atom from renewable and add that into a huge tank of dirty hydrogen...Technically you could claim that the hydrogen is sourced from renewables.
