The Hydrogen Stream: H2Mare project links electrolyzers to wind turbine (www.pv-magazine.com)

The German government says that the H2Mare OffgridWind project in Denmark has connected two electrolyzers to a wind turbine for hydrogen production, while Ontras Gastransport and H2 Energy Europe have agreed to define the technical and commercial framework for hydrogen transportation in its Green Octopus Mitteldeutschland pipeline project.

GreenGo Energy will also collaborate with Lodestone, a local iron mining company, to integrate green hydrogen into steel production, aiming to set new standards for sustainable manufacturing.

Especially in Europe there is a big question of winter energy demand not meeting supply from solar. That causes issues that wind doesn't fully solve.

So I get that hydrogen could be an option to balance the grid over yearly time periods. Although I think batteries still look better.

But so much of hydrogen just seems like a scam

It added that all necessary equipment could soon be housed on a platform directly on an offshore wind turbine

Like why would you even do that? I don't get it. It must go from kinetic energy to electrical then to the hydrogen plant surely. Why wouldn't you send that electricity back to shore?

From the article, it looks like the focus is on the more relevant parts for hydrogen, the chemical and steel industries.
Those and long haul vehicles (planes and ships) seem like the places where hydrogen is more relevant / the only realistic option at the moment.

They can make steel with just electricity and I don't see why if you are making a fuel for planes why you wouldn't make straight kerosene.

I can see how you could mass produce hydrogen for industry then use it in winter. But I can also see all high energy industries going to places with good solar.

The future is going to be weird that's for sure.

~~No~~. Here's why.

Edit: ok, guess it is possible.

Here's a company doing it. https://www.canarymedia.com/articles/clean-industry/green-steel-without-green-hydrogen-can-it-work

We need hydrogen production because we need emissions free steel, fertilizer, and vehicle fuel. It's also a good way to soak up excess electricity production. Sure, batteries can store energy arguably more efficiently, but they offer no practical benefits beyond that.
