Citizen pay for big industry. There have to be built and are already under construction new pipelines. It seems that here the citizens have to pay for it, but the green hydrogen is mainly used by large scale industry. So the “clever” large-scale industry probably passes the costs on to the citizens. https://www.vzbv.de/publikationen/faktenblatt-zu-gruenem-wasserstoff
Uncontrollable hydrogen (blue or grey) or other gas can be delivered in pipelines. Liquid gas from other energy sources as nuclear power might be delivered in the big pipelines TV, ARD, 1. Deutsches Fernsehen, Broadcast Monitor 4/29/21 | 07:46 min. Summary: Politics and the gas industry are selling green hydrogen as a central building block for the energy transition. But critics are skeptical: green hydrogen will be scarce and expensive. The gas industry is only using it as an excuse to secure its fossil gas business for decades. In the interview, the German politician Report the politician Altmaier can be seen versus various German professors.
Too much water consumption. A lot of drinking water is probably needed for the production, but drinking water is precious and scarce on the planet. https://oilprice.com/Energy/Energy-General/The-Green-Hydrogen-Problem-That-No-One-Is-Talking-About.html. It seems that a lot of drinking water is consumed by the process and this drinking water becomes contaminated - but afterwards this water has to be cleaned again.
Poor efficiency. We have to build up far too many green energy sources to get relatively little green hydrogen. The technology results in a lot of losses. Here I present the German Wikipedia translated into English: German Wikipedia, Green Hydrogen, criticism: “A study by Greenpeace Energy came to the conclusion at the end of 2020 that the use of green hydrogen would only serve to protect the climate if there was an abundance of green electricity due to its comparatively poor efficiency.[8][9] The German Nature Conservation Union (NABU) demands, among other things, a complete life cycle assessment of green hydrogen.[10]”
