We do not yet have green hydrogen in abundance, but with the emergence of large wind farms at sea, the need for green hydrogen and therefore its production will increase incrementally in the coming years. We are going to see a revolution similar to the invention of the steam engine or the introduction of the internal combustion engine. As an example how fast things can change: around the year 1900 the largest problem on public roads in New York City were horse droppings. You did not hear anyone talking about it just a few years later.
We wrote this article in response to the article as mentioned above.
Am I saying that battery cars have no future? In the contrary. Battery cars and hydrogen cars will soon be driving around next to each other on the road. A lot of rides can be driven without hydrogen, which mainly offers a larger range and can be refueled quickly. That will offer a solution for taxis, police and heavier transport as well as ships and aircraft.
Another aspect that is often forgotten is that hydrogen can really help us make the zero emission energy transition AND make it affordable. I started with that in the first paragraph. We will need to store energy in large quantities (for the winter, export, use elsewhere). Batteries, and in particular our electricity network, are not or only to a very limited extent suitable for storage of energy, certainly if large distances and or longer periods of time need to be bridged.
