Viable for what?
Currently most fertilizer is made with hydrogen that's separated from methane and the CO2 vented.
It's about 2% of global emissions.
Ammonia and Methanol and other efuels for shipping and flight generally require hydrogen as a building block.
The Hydrogen Ladder diagram lays out the areas where Hydrogen is necessary and where better current alternative tech exists. It gets updated every so often as tech progresses but generally shouldn't see any major changes.

- ZeroGravitas 3y agoWell, long duration grid balancing gets a B on the ladder. Short duration grid balancing gets an E as renewables/batteries compete. And power generation with no storage component gets a G, the lowest score possible.
- sofixa 3y agoI mean, many many many people and companies are trying to get hydrogen to work. From airplanes to cars to long term energy storage. From random startups to Airbus and Toyota going through universities. There are good reasons for that, or there wouldn't be that many reputable organisations spending that much money on trying to make it work.
