Joint Venture With Linde AG And £38M Strategic Investment

The title of this post, is the same as that as this Press Release from ITM Power.

This is the first paragraph.

ITM Power plc  is pleased to announce its intention to raise at least £52.0 million (before expenses) through (i) a strategic investment of £38.0 million at 40 pence per share by Linde UK Holdings No. 2 Limited, a member of the Linde AG group (Linde) (the Share Subscription); and (ii) a conditional placing of £14.0 million at 40 pence per share (the Firm Placed Shares) with certain existing and new institutional investors (the Firm Placing).   The Group has also entered into a 50/50 joint venture with Linde (the Joint Venture) which will focus on delivering green hydrogen to large scale industrial projects, principally those with an installed electrolyser capacity of 10 Megawatts (“MW”) and above.

There is all the usual financial stuff and these sentences.

The net proceeds of the fundraising will be used principally to enhance the manufacturing capabilities of the Group, particularly for the development and production of large scale 5MW electrolysers, to facilitate product standardisation and manufacturing cost reduction.

The Joint Venture will focus on delivering green hydrogen to large scale industrial projects (generally being opportunities with installed electrolyser capacities of 10 Megawatts and above)

As ITM Power are constructing the largest electrolyser factory in the world, at Bessemer park in Sheffield, it appears to me that ITM Power are going for the larger scale hydrogen market.

Recently, I wrote these three posts.

News stories generated about the company or the production of hydrogen seem to require large electrolysers in excess of 5 MW.

It looks like ITM Power are setting themselves up to tap this market substantially.

How Much Hydrogen Would A 5 MW Electrolyser Create In A Day?

I found the key to the answer to this question on this page of the Clean Energy Partnership web site.

To produce hydrogen by electrolysis directly at the filling station, the CEP currently requires about 55 kWh/kg H2 of electricity at an assumed rate of efficiency of > 60 percent.

To produce 1 kg of hydrogen, nine times the amount of water is necessary, i.e. nine litres.

I will use that figure in the calculation.

  • A 5MW electrolyser will consume 120 MWh in twenty-four hours.
  • This amount of electricity will produce 2,182 Kg or 2.182 tonnes of hydrogen.
  • It will also consume 19.64 tonnes of water.

In Surplus Electricity From Wind Farms To Make Hydrogen For Cars And Buses, I described how Jo Bamford and his company; Ryse Hydrogen, have applied for planning permission to build the UK’s largest electrolyser at Herne Bay in Kent.

  • It will produce ten tonnes of hydrogen a day.
  • The hydrogen will be sent by road to London to power buses.

So could the electrolyser be a 25 MW unit built of five 5 MW modular electrolysers?

Linde and their UK subsidiary; BOC, must have a lot of knowledge in transporting tonnes of hydrogen by road. I can remember seeing BOC’s trucks behind ICI’s Castner-Kellner works in the 1970s, where they collected hydrogen to see to other companies.

Big London Hospital Was Close To Running Out Of Oxygen

The title of this post is the same as this article on  The Times.

With COVID-19 and all those ventilators and CPAP devices, this sounds like a tragedy about to unfold.

I also remembered a story told to me by a friend, who used to be the Chief Pharmacist at a London hospital.

Oxygen was one of their problems, as the tanks were in a small yard with gates opening on to a busy street, about two hundred metres, away from the hospital.

The problem was that illegal parkers would block the gates, so that delivery couldn’t be made.

Knowing my physics and the reliability of deliveries in parts of London, I thought on-site electrolysis might be a better idea. So I consulted my bible.

There on page 760, it is all described how water can be split into two molecules of hydrogen and one of oxygen by electrolysis.

ITM Power are the experts on electrolysis, so I sent them an e-mail and asked if they could make an electrolyser, that produced oxygen instead of hydrogen.

The reply came swiftly and confirmed, that they could make an electrolyser that supplied oxygen. They also said, that the oxygen was of a high purity.

Just Connect Electricity And Tap Water

All these electrolysers would need is supplies of electricity and tap water to create hydrogen and/or oxygen.

No trucks would be needed to deliver tonnes of liquid gases, which can be rather dangerous to move around city streets.

ITM Power’s hydrogen electrolysers are starting to appear in filling stations, so they can refuel hydrogen-powered vehicles.

One could be installed in a hospital to provide a continuous stream of pure oxygen, which could be piped into the current oxygen delivery system.

What To Do With The Hydrogen

The hydrogen electrolysers produce oxygen as a by-product, which I suspect is just vented to the atmosphere!

But you can’t vent large amounts of hydrogen to the atmosphere, as it is an inflammable gas!

However, you could do either of the following options.

  1. Connect it to a hydrogen fuel pump to refuel hydrogen vehicles.
  2. Inject the hydrogen into the gas main, as is regularly done with hydrogen produced by surplus renewable electricity.

I prefer the first option, as it could mean that health-care could start to use hydrogen-powered ambulances, that are zero carbon and pollution-free.

Perhaps not an appropriate saying for the industry, but it would genuinely kill two birds with one stone.
