The vision of the European Union is that the future is renewables + hydrogen. Initially I was skeptical, but recently I realized that it does make a lot of sense. You can start by first converting coal power plants to natural gas. That will cut the emissions by at least a factor of 2. Then, when the hydrogen infrastructure is built up, you replace the natural gas with hydrogen. Initially it can be "brown" hydrogen, but then you can transition to "blue" hydrogen, and finally with green hydrogen [1].
