Hydrogen comes to recue of electricity production?
https://www.telegraph.co.uk/business/2021/03/11/hydrogen-revolution-real-will-change-world/"This is what is happening today. If you want a futuristic leap, try the new hydrogen paste unveiled by Germany’s Fraunhofer Institute. They have found a way to make the gas safe, portable, and energy-dense. “It stores hydrogen in a chemical form at room temperature and atmospheric pressure,” said project leader Marcus Vogt.
You insert a cartridge of paste into your car. A plunger squirts out a dose and that mixes with water to produce hydrogen for the fuel cell, and runs the vehicle. A single fill potentially has longer mileage than a full tank of petrol."
"“The way we see the future, in 20 to 40 years from now, all the energy that mankind uses will come from wind, solar, and hydro. Forty per cent of this will be used directly to power electric vehicles, heating, light, air conditioning, and cooking. The rest will be used to break down water and produce hydrogen. That will be the source of energy to drive trucks, ships, trains, and industries like steel,” he said.
That sums it up in a nutshell. You move through the gears, first displacing natural gas as a dispatchable back-up for renewables, then reaching cement, fertilizers, chemicals, or heating for buildings. The scissor-action of falling hydrogen prices and rising carbon prices brings one sector after another into range."
