The idea of using excess wind energy to make hydrogen has sparked great interest, not least because governments are looking to move towards greener energy systems within the next 30 years, under the terms of the Paris climate agreement.

Hydrogen is predicted to be an important component in these systems and may be used in vehicles or in power plants. But for that to happen, production of the gas, which produces zero greenhouse gas emissions when burned, will need to dramatically increase in the coming decades.
Mr Matthews says his firm's project is just getting going, with a prototype system using a floating wind turbine of roughly 10 megawatt capacity planned, but not yet built....


This looks promising.

Sounds good, , , , ,!

I've been reading that there are those that are saying that the whole "EV" thing is not what it is cracked-up-to-be.

Some used to think that hydrogen could make more sense as a vehicle fuel than batteries.
I don't think so much anymore. The density advantage doesn't outweigh the cost so much now that batteries are so much better and cheaper.
Maybe for some transportation uses. (long haul trucks, aircraft?)
Maybe just the cheapest way to store and move energy from such a distant point of production.

That stuff causes cancer, you know. But, as long as it's off shore, it's OK, right?

Hydrogen is a pretty cool fuel but still a puzzle. You can burn in an ICE, remember the BMW Hydrogen 7?, but ICE efficiency is too low to make good use of it. To solve the energy density problem, you need to run s fuel cell instead. Since hydrogen has about a third the volumetric fuel density of gas, and fuel cells can be up to 3x more efficient than ICE, it evens out. As long as the hydrogen comes from wind/solar electrolysis, not methane reformation, it's green.

Well said, Tom. What's your take on this?
Using anhydrous ammonia as jet fuel

First I'd heard of it but here are my two immediate thoughts. First, most ammonia comes from the Haber-Bosch process. Who was Haber you ask? Ya, you don't hear much about him, he's kinda know as the father of chemical warfare so no Nobel prize or anything. I digress. Anyway, that process uses hydrogen and nitrogen to make ammonia and the same thing applies as above. Hydrogen from wind/solar hydrolysis good, hydrogen from methane, not so good, heck just burn the methane and be done with it,haha. Or alternately, if you got green hydrogen, why not use that as a fuel. Rockets love hydrogen because the gravimetric (not volumetric) energy density is awesome. Think Shuttle main engines. Why not planes? Anyway the second thought is that oxidizing a nitrogen bearing compound like ammonia has got to result in tons of nitrogen oxides, that brown air smog stuff that VW got in such trouble for. I dunno if airline engineers are as good as VW engineers about programming those emission chips.

Likewise Tom, thanks. I'm shocked I overlooked the NOx aspect, especially after owning one of those ill-fated VW TDIs. Shiny distractions. All that glitters is not gold!

This old technology is new again and the hydrogen byproduct is the goal.

>> And while hydrogen is the direct product of the battolyser, other useful substances can be generated from it too, such as ammonia or methanol, which are typically easier to store and transport. "Having a battolyser in place, [an] ammonia plant would run more constantly and [would] need less manpower, reducing operating costs and maintenance costs, thus producing ammonia the cheapest way in a sustainable, green manner," says Hans Vrijenhoef, chief executive of Proton Ventures, who has invested in Mulder's battolyser.<<
