Why does every article about hydrogen keep saying this? Running electricity through fresh water generates hydrogen and oxygen. The electricity can come from the nuclear power plant, a solar array, etc...
What am I missing since I first saw hydrogen and oxygen created in high school chemistry?
- sp332 5y agoThere was a recent study about generating hydrogen using power from natural gas and capturing the carbon dioxide from it. It found that methane leaks almost certainly made it too dirty to consider as a green energy source. https://arstechnica.com/science/2021/08/blue-hydrogen-pushed-by-gas-companies-harms-climate-more-than-coal-study-says/ https://arstechnica.com/science/2021/08/blue-hydrogen-pushed... I agree the article left out this important context.
- freemint 5y agoThat's just an attempt to make fossil fuels produce green hydrogen. A thing often attempted by the fossil fuel industry to stay relevant. There are other ways to make hydrogen from water.
- ufo 5y agoThe problem is that it is cheaper to produce hydrogen using fossil fuels, instead of using clean energy + eletrolysis. https://en.wikipedia.org/wiki/Hydrogen_production https://en.wikipedia.org/wiki/Hydrogen_production > As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification.
