Hydrogen as such can't replace fossil fuels as it needs to be produced first using energy.
It is only a vector. So many people make the confusion thinking that hydrogen is the solution.
- epistasis 4y agoThe article goes into deep discussion about this, and is actually fairly reasonable, and the plan looks fairly realistic (except perhaps fuel).
- Ma8ee 4y agoI don't think ever had been suggested as a source of energy, only as a form of storage.
- kumarvvr 4y agoThe idea is that energy from renewables can be converted to Hydrogen, which acts as a store of energy. It is a better store of energy than batteries, as scaling up batteries to grid scale is next to impossible. Hydrogen, however, can take advantage of existing gas and oil infrastructure. And once a critical mass is reached, along with electrification of transportation, we can drastically reduce oil usage.
- ncmncm 4y agoScaling up batteries to grid scale is very far from "impossible". You just need a hell of a lot of batteries, so it is expensive. Other, cheaper systems will be favored. Systems and procedures for LNG can probably be adapted for LH2 with not too much difficulty, but ammonia will be the more practical choice, most places.
- kumarvvr 4y agoBatteries alao have the additional burden of recycling and pollution issues of their own. Not to mention replacement every 10 to 15 years. When it comes to Hydrogen, its basically industrial compressors, tanks, piping, etc.
- ncmncm 4y agoNot all batteries are exactly like the ones in cars.
