Reply to comment by vVWARLOCKVv in Dutch pilot project for hydrogen heated homes allowed to begin by alex20_202020

Excess wind/solar can be stored as hydrogen, at much lower cost compared to batteries (although in a much larger volume if we're talking about low pressure safe storage). It can then be fed into the local heating grid. Unsure about long distance supply since Hydrogen makes steel pipes brittle.

I don't remember where in UK/Ireland/Scotland but there was this infrastructure moves a while ago to change pipes from steel to plastic based which support hydrogen transport from what I remember. The results where good but the investment is massive iirc.

Yeah, but it's a terribly inefficient storage medium when compared to batteries. Works fine, i guess, but you're losing a lot of power and it'd be best to use short term while mass battery manufacturing gets into place and can be leveraged.

Even then, the sunk cost in the infrastructure for hydrogen might not be worth it over more expensive batteries, because then you need far more power generators to make up the power difference alone. This doesn't include retrofitting homes for hydrogen usage over electricity, the infrastructure for which is already in place.

Family are in this industry.
There is definitely a market for production of hydrogen in cheap areas and transport via tanker to other countries as a method for moving green energy around.

Must be some expensive equipment to either contain the pressure or maintain the liquid state. The same with in-home equipment. Honest question: do you know how much investment was made in just the hydrogen portion of the transport? Not the regular truck parts, but the cost of just the hydrogen containment.

Another commenter was talking about retrofitting the gas lines, which would also be a pain.

It can't. Storing hydrogen is complicated and expensive.

I think you are being a little too obvious here in your trolling. Was not sure if you were being sarcastic.

The energy used to electrolyze has to come from somewhere. Likely requiring more methane produced energy on the grid.

I don’t get why when they say “hydrogen produced with renewables” you think that involves methane. It’s electrolysis of water.

Because that’s not how the grid works. Are they adding new capacity to electrolyze with? No they aren’t, they are drawing from a grid that is not 100% renewable currently.

The overwhelming majority of H2 production uses either methane or coal, less than 2% is green hydrogen. You have to ask yourself who benefits here?

here’s another article about it They are using green hydrogen. If you know anything about the Dutch you would know they are not going to forget about using renewable energy to power electrolysis.

The marketing is working on you. Are you also a fan of “self charging” hybrid cars?

I get that you are cynical but did you read the linked article? This is a pilot project to see if “green hydrogen” could be a viable option in Europe. Maybe if you followed the news you would realize there is a big push to wean themselves off Russian gas/methane. They are going to try to use water as a hydrogen source and renewable energy because that is a native source of energy.

Maybe realize your cynicism comes from a different kind of marketing. Who benefits when people discount the possibility for change? Oil companies love people like you.
