this kind of headline is bad for our collective souls; I know raging against the clickbait is old hat but seriously, this is ridiculous. Materials science is surely interesting enough to a reader of science direct without being SHOCKED and APPALLED all the time
You just know that engineers and management in Toyota's delusional hydrogen division are salivating.
Nope. Splitting water into free hydrogen and oxygen is important because it is an essential step for using electrical energy in the chemical and metallurgic industries. For long term energy storage, free hydrogen is not a good solution, but it can be used to synthesize hydrocarbons, which are suitable for long term energy storage or for aerospace transportation. Even with abundant and cheap dihydrogen, using it for e…

With CO2 emitting option is priced out or banned, direct hydrogen production using high temperature sulfur–iodine cycle without H2 electrolysers could be economic option. The heat could be supplied from high temperature nuclear reactor.
How to make hydrogen production cheaper and easier: include an atomic reactor component. Huh? I’d be interested in hearing about some scenario where this actually costs less, given the cost of building anything nuclear in 2026.

Japanese car manufacturers were late to EVs, and in order to prevent a gap in the market where EV-first competitors can steal market share from them, they lobby the government to subsidize and create a new market segment in the form of hydrogen cars. There they have a head start via some latent research and more reuse of ICE car platforms. I'm sure the hydrogen division is well aware that they are doing research on a dead-end technology (at least for the automotive sector).
The exact same thing happened in Germany. In 2020 there was a huge push from politicians to push more hydrogen technology to distract from the fact that German car manufacturers were lagging behind, as well as general missed initiatives for renewable energy. Now, 6 years later those initatives are deader than ever.

How does this refute the comment you replied to? That comment was implying that Toyota Mirai et al are ill-advised, so seems like your "nope" should be a "yep."
It's important to always appear to be argumentative, even when in agreement.

I agree, the experience building nuclear reactors is mixed bag. Some builds failed, like Flamanville 3, Hinkley Point C, Vogtle 3. Some builds succeeded: Barakah nuclear power plant, Fuqing 5,6. It really depends on maturity of supply line and political support.

> unless government policies mandate it or restrict batteries or blue hydrogen Yes, but I think this the most likely outcome. Natural gas is only cheap in certain areas, and the past few years have made everyone very, very aware of the geopolitics involved in getting hold of it. While global warming is not going away, and I question the extent to which CCS actually happens with blue hydrogen. Batteries are capital eq…
