Plug Power Lands 1 GW Electrolyser Order

[source]

Electrolyser maker Plug Power has landed an order to deliver a 1GW unit — the world’s biggest to date — to hydrogen company H2 Energy Europe as part of an offshore wind-powered project in Denmark that is foreseen generating enough green fuel to run some 15,000 heavy duty vehicles.

North Sea to Become World’s Largest Green Power Plant

Signing ceremony in Esbjerg today

Germany, the Netherlands, Denmark and Belgium signed several agreements today in Esbjerg, Denmark, related to a newly decided massive expansion of wind energy plans. This is about 150 GW wind capacity in the North Sea until 2050, subsea interconnectors, energy islands to collect and distribute electricity to the EU and the production of hydrogen.

Nothing is being decided that hadn’t already been identified as potential. It is just that events in Ukraine has hardened the resolve to realize that potential, no ifs or buts. From now on, it’s all systems go. It’s unclear, however, how this joint 150 GW is going to be distributed over the 4 cooperating countries.

Additionally, the ambition is to phase out Russian fossil fuel completely by 2027 from the EU.

Industrial Wood Pellet Sector

The global trade in wood pellets is growing. Importers are mainly the forest-poor (prosperous) countries. With 177 kg/inhabitant, NL was the second largest importer in 2021. The leading importer of wood pellets is DK, where they are used as feedstock for heat networks.

Green Hydrogen Systems Electrolyser Tour

Your questions on green hydrogen and electrolysers answered!

I visited Green Hydrogen Systems in Kolding, Denmark to ask an expert all about electrolysis and electrolysers.

01:11 How does an electrolyser work? (tabletop electrolysis demonstration)
01:49 What are the components in an electrolyser?
02:30 What consumables does the process use?
03:17 How can we make electrolysis more efficient?
04:25 What are the advantages of alkaline water electrolysis compared to PEM (polymer electrolyte membrane) or SOEC (solid oxide electrolyser cell)?
05:09 How much does an electrolyser cost? (levelized cost of hydrogen, capex, efficiency)
06:07 What do you do with the oxygen after you split water?
06:39 Electrolyser tour: an up-close look at a real electrolyser
08:06 Do you have to use pure water for electrolysis, or can polluted or salt water be used?
08:46 How much hydrogen can a shipping container sized electrolyser produce?
09:02 Applications for hydrogen: will we use hydrogen to store and generate electricity?
09:46 What about the low efficiency of using electricity to make hydrogen instead of just using electricity directly?
11:01 How do you calculate the efficiency of an electrolyser? (electrolysis thermoneutral voltage)
12:06 How much more efficient can electrolysis get?
12:26 What kinds of improvements are needed to improve efficiency?
12:59 How long will it take to develop a more efficient electrolyser?
13:16 Is it realistic that the price of hydrogen can come down as quickly as it is predicted to?

“There’s a natural hierarchy somehow, you should use electricity as electricity for all the cases you can. Of course, that’s obvious. But when you cannot use electricity, you need to convert it to something else. And then hydrogen is a very good candidate.”

This was the answer from Kasper Therkildsen, Head of Technology at Green Hydrogen Systems, during our recent tour/ interview when I questioned the low efficiency of using electricity to make hydrogen relative to just using electricity directly.

We discussed likely applications for hydrogen (Kasper anticipates transportation, industrial purposes and in some cases process heating), and we ran through as many as time allowed of the fifty viewer questions you all suggested ahead of the tour.

There’s a benchtop demonstration of alkaline water electrolysis, we talk electrolyser technology development, how much more efficient it can get (and how, and how quickly).

But is it realistic that the price of hydrogen can come down as fast as it is predicted to? According to Kasper:
“10 years back nobody believed that the price of electricity would be where it is now from renewable sources. And we’ll see the same with hydrogen. You know, once things get rolling, it’s gonna be tremendous.”

Thanks to Kasper Therkildsen and the rest of the team at Green Hydrogen Systems for spending an afternoon with me and patiently answering all of my questions!

Ørsted Eyes 27MW Offshore Wind Turbines

[source] In 2020, Danish wind developer Ørsted installed offshore wind turbine #1500, with a size of 8 MW. The company is just getting started.

Ørsted is involved in preparing the installation of the 1.5GW Skåne Havsvindpark and has announced it is investigating the realization of 27 MW turbines, with a 320m rotor diameter and rotor tip heights of 385m. This would be double the size of state-of-the-art turbines today. Estimated operational date: 2029.

The Baltic Sea region has the potential for more than 90 GW of offshore wind power, with Sweden accounting for 20 GW of that, Ørsted said.

Green Hydrogen of €2.87/kg Coming up in Portugal

A group including some of Europe’s biggest energy players aims to demonstrate highly efficient and flexible green hydrogen production on an “unprecedented scale” with the deployment of a 100MW electrolyser in Portugal.

Led by local renewables champion EDPR, the GreenH2Atlantic project in Sines also includes Vestas, Engie and Martifer, as well as Portuguese oil & gas group Galp in an effort to hit a levelised cost of hydrogen of €2.87/kg ($3.24/kg) – a level that would make green H2 significantly more competitive in the market than previously… The partners said they hope to start construction in 2023, with operations beginning in 2025 subject to permitting.
