This is still important, even if right now the hydrogen comes from natural gas. Otherwise, it's a chicken and egg problem: if there's no demand for hydrogen, people won't build plants to make green hydrogen, and if green hydrogen is not available, people won't build the trains and other vehicles to use that.
- a3_nm 4y agoThere is in fact already significant industrial use of hydrogen https://en.wikipedia.org/wiki/Hydrogen_production#Use_of_hydrogen https://en.wikipedia.org/wiki/Hydrogen_production#Use_of_hyd... -- independently from the use case of replacing fossil fuels. So there is already significant demand for hydrogen that could be green, but the vast majority of hydrogen produced today is from fossil fuels.
- credit_guy 4y agoThat is true. But the vast majority of the hydrogen produced today is used for things hydrogen was used for decades (fertilizers and oil refining). As such it already has its infrastructure in place, so it's quite a change to migrate to a new way of producing this hydrogen. New uses can demand green hydrogen however. Germany in particular has a number of green hydrogen producing projects. [1] is a very good source. [1] https://www.iea.org/reports/hydrogen https://www.iea.org/reports/hydrogen
