Hydrogen electrolyser plant. This sounds like a load of greenwash to me?

I tried googling “lysers” but didn’t find anything, can you expand @Post and beam?

Hi @joe90   My guess is electrolysers

Turbines in areas of directional current. 

 

 

Wave power from 'nodding duck' and similar seems to hsve never quite worked. Maybe it was my fault, overflowing the flume down onto his desk.

Electrolysers dude.

Ah, to produce oxygen

And drinking water as it happens. Dumped the Hydrogen to sea

500 amps, 500 degrees F and cannot remember the pressures. Went to see with only one of the two functional once. The second one fell over with two weeks of the Patrol left. That was fun.

They use them offshore in two variation, but most are use for making hypochlorite (strong bleach) - hydrogen is vented as a waste by product.

 

Never very reliable. Simple process but the controllers are almost an after thought and generally rubbish.

Wasn't there a tidal generator operating in Strangford Lough for around ten years. Don't think it's there any longer, don't know why.

But the final thought, would it not just be simpler for the distilleries just to use electricity for their production?

 

They probably only want it for their own delivery trucks.

That is tidal, not wave, generation.  A totally different beast.

 

To give you an idea of how much power is in a wave, this is Penzance on a quiet day.

 

 

A 1 metre swell and for every meter of wave front, 2.5 kW is produced.

That is a lot of wallop.

It does not seem to be best use of hydrogen in a fixed location such as a distillery. Electrification would in my mind be a better solution, and not reliant on a single source of supply of hydrogen.

 

In my day job I have come across a few recent examples of cascaded ASHP and WSHP in order to achieve suitable grade heat for hospitals including for their DHWS which is required at least at 60 C for protection against legionella in areas for vulnerable patients. This must be somewhere near the grade of heat required for distillation.

I think the distilleries agree, and most use entirely electric energy. 

Mme Pernod owns lots of them and says how proud she is etc. Heat recovery saves half the power apparently. 

So I'm guessing hydrogen powered tankers will be the thing.
