Reply to comment by Timbershoe in Hyperion plans to kickstart a H2 fuel network with mobile stations by redingerforcongress

You could have said the same about petrol in 1899 when electric was so clearly dominant. Even then steam took another 50 years or so to completely die out for road transport. Don't write it off so soon.

This isn’t 1899.

It’s not Carl Benz knocking together 10 horseless carriages a year from a shed, trying to work out if his electric engine or petrol engine was better.

Trillions of dollars have already gone into electric vehicles, development, infrastructure, technology, manufacturing plants. There has to be a fucking serious reason to write off that investment in favour of hydrogen vehicles.

And what is that seriously compelling reason? Hydrogen vehicles are both more expensive and less efficient, so there is literally no reason to switch.

It’s a simple choice, and the choice was made 20 years ago.

Maybe in 30/40 years when electric vehicles run out of key metals for battery production. But not today, hydrogen is a solution to a problem that doesn’t exist.

The key reasons I say it's not dead are twofold

  1. Major companies are still investing in hydrogen as a fuel for other uses. Rolls Royce in jet engines for example.

  2. Japan generates a lot of hydrogen as a byproduct of other industries, so there are situations in which it becomes cheaper and the Japanese manufacturers have always kept it in the system as a concept for this reason.

Now I'm no great hydrogen evangelist, I know it has some fundamental flaws, but it's not yet dead. If there is a solid reason to build large scale hydrogen infrastructure it may yet come back for cars, or possibly commercial vehicles. However the next 20 years will certainly be the age of battery EVs for personal transport.

Oil companies. Most commercial hydrogen is made from natural gas. The fossil giants have the most to gain by miles.
