Solarpunk@slrpnk.net•What's geologic hydrogen? What to know about the clean energy source buried under Michigan.English
2·3 days agoIt is almost certainly greener than using more fossil fuel. This is an idea that should be explored.

Hydrogen@piefed.social•Hydrogen Powerpaste: 10x Higher Energy Density & Safe?English
1·5 days agoThis idea allows for relatively easy extraction of hydrogen. Extraction of hydrogen from water is extremely endothermic and would not constitute a real way of storing hydrogen.

33·9 days agoThey are failing at basic editorial controls. This is not a “pretty good fucking job.” It is a sign of real decline.

213·10 days agoIt’s one of the stages of enshittification. Unless we see hard changes to avoid further decay, Ars will inevitably get worse and and worse until it does become an “internet rot site.”
Which is why Discord should die. It made the Internet much less accessible.

PieFed help@piefed.social•Is sort by "Active" using the wrong methodology?English
5·23 days agoOk, in that case, we should call it “new comments.”

Hydrogen@piefed.social•South Korea Is Reinventing the Tank—and Betting Big on Hydrogen FuelEnglish
2·1 month agoHydrogen is lighter than air, which means that any fire would be much more brief and hard to sustain.

Green Energy@slrpnk.net•Electricity Should Be Free at Noon | And two other ideas for lowering electricity costsEnglish
2·3 months agoThose are outright lies. For one thing, you can use fuel cells instead of gas turbines, getting rid of NOx emissions entirely (not to mention you can filter out NOx even with gas turbines).
Sorry, but this conversation cannot continue if you proceed with dishonest arguments.

Green Energy@slrpnk.net•Electricity Should Be Free at Noon | And two other ideas for lowering electricity costsEnglish
21·3 months agoIf you adopt hydrogen for energy storage, you no longer have to worry about “where.” You have a solution that is nearly geographically independent.

Green Energy@slrpnk.net•Electricity Should Be Free at Noon | And two other ideas for lowering electricity costsEnglish
2·3 months agoThe more renewable energy you have, the more you need long-duration energy storage. You cannot reach 100% renewable energy without huge amounts of it.

Green Energy@slrpnk.net•Electricity Should Be Free at Noon | And two other ideas for lowering electricity costsEnglish
2·3 months agoFor a few hours, yes, but that will make up a small percentage of total energy stored. To really solve the intermittency problem, you will need large scale energy storage.

41·3 months agojust use excess electricity to make hydrogen. This actually solves the intermittency problem, among many other things that will require hydrogen in order to reach zero emissions.



















It is happening to me too.
