Reply to comment by drsnafu in Egypt inked deals on renewable energy, green hydrogen worth $119 bln by Wagamaga

Hydrogen is not a source of energy. Is an energy carrier. The main sources of energy are nuclear and solar. All others derive from these two. Exceptions may be tidal and geothermal but they constitute a very small fraction. Green hydrogen could be useful for industry but I have yet to see a big scale plan for it.

Right now a huge chunk of it comes from natural gas

Indeed. But natural gas is just another carrier, the source of it is solar anyway. That’s why usually we speak about sources of electricity, types of electricity production or electricity mix.

Most SMR plants I have seen burned fossil fuels do you have any source that says otherwise

I haven’t said otherwise. I just said that fossil fuels are not a source of energy, just a carrier, it embodies solar energy captured millions of years ago.

Solar comes from nuclear fusion so there is only type of energy if you want to use that logic, but calling fossil fuels solar energy is deliberately misleading
