Marc Tarpenning, co-founder of Tesla, believes hydrogen fuel cells are a “scam”. Tarpenning, who is not with Tesla anymore appeared on Internet History Podcast last week to outline a number of issues with hydrogen fuel cells. He said (via Electrek blog): If your goal is to reduce energy consumption, petrol or whatever resource, you want to use it as efficiently as possible. You don’t want to pick something that consumes a lot for whatever reason, and hydrogen is uniquely bad. There’s a saying in the auto industry that hydrogen is the future of transportation and always will be. It’s a scam as far as I can tell because the energy equation is terrible. People will say that hydrogen is the most abundant element in the universe, but it’s abundant out there in the universe not here. We live on a planet where hydrogen is super reactive — it’s bound up into everything. It’s bound up into water, wood and everything else. They only way that you get hydrogen requires you to pour energy into it to break it from the chemical bonds. Electrolysis is the most common method. You put electricity in water and it separates it, but you are pouring energy in order to make hydrogen, and then you have to compress it and that takes energy, and then you have to transport it to wherever you actually need it, which is really difficult because hydrogen is much harder to work with than gasoline or even natural gas — and natural gas is not that easy. And then you ultimately have to place it into a car where you’ll have a very high-pressure vessel which offers its own safety issues — and that’s only to convert it back again to electricity to make the car go because hydrogen fuel cell cars are really electric cars. They just have an extraordinary bad battery.Here’s the podcast.
