Hydrogen Fuel Cell Trucks And H2 Infrastructure Could Benefit From New Legislation

The title of this post, is the same as that of this article on Hydrogen Fuel News.

Politicians from both main parties in the United States are promoting a Hydrogen for Trucks Act, to support the conversion of domestic trucking from diesel to hydrogen.

These are the three main parts of the Act

  • Provide incentives for adopting hydrogen fuel cell trucks by covering the difference in cost between them and conventional diesel-powered vehicles.
  • Encourage tandem fueling station and vehicle deployment, to ensure that one doesn’t need to exist before the other is in place, solidifying the overall fueling infrastructure.
  • Collect data and establish benchmarks for various forms of fleet operation, helping to accelerate deployment by incentivizing private investment.

We could do with an Act like this in the UK.

But whereas the United States would start with hydrogen for trucks, we would probably start with hydrogen for buses.

World’s Largest Floating Offshore Wind Farm Fully Operational

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the first paragraph.

Located 15 kilometres off the coast of Aberdeenshire, Scotland, in water depths ranging from 60 metres to 80 metres, Kincardine is the largest operating floating wind farm.

Note.

  1. Wikipedia has a comprehensive section on floating wind turbines.
  2. Kincardine Wind Farm has a capacity of 50 MW.
  3. Its turbines are mounted on WindFloats, which were designed by Principle Power, who have this page on their web site, which describes advantages of the technology.
  4. The Kincardine wind farm appears to have been developed by Spanish company; Cobra and there are pictures on this page on their web site.

The WindFloats are triangular floating structures, which are based on semi-submersible offshore platform technology, that has been used in the offshore oil and gas industry since the early 1960s.

Semi-submersibles have good ship stability and seakeeping, so they would seem to be an ideal way to create a fixed structure in deep water on which to mount a wind turbine.

  • The hull structure can be well below the surface of the sea, so they are not affected by waves.
  • If they have a problem, it is handling changes of load on the platform. But this is an advantage with with wind turbines, as the load will be constant.
  • Standard wind turbines can be used.
  • All platform construction can be onshore rather than in the middle of a ferocious ocean.
  • The platforms can be towed into position and moved into sheltered waters for servicing.

In Are Floating Wind Farms The Future?, which I wrote in 2020, I laid out my experience and views about floating wind farms.

I came to this conclusion.

It is my view, that floating wind farms are the future.

But then I’ve done the mathematics of these structures!

Did Boris’s advisors, as I doubt he knows the mathematics of oblique cylinders and how to solve simultaneous differential equations, do the mathematics or just read the brochures?

I will predict, that today’s structures will look primitive to some of those developed before 2030.

WindFloats seem to have fulfilled my predication and it’s only 2022.

How Big Can Floating Wind Turbines Get?

Platforms like WindFloat would appear to create a stable island that is as secure a mounting, as say a solid hill.

So I suspect that platforms can be created for the world’s largest wind turbines.

This article on offshoreWIND.biz is entitled World’s Largest, Most Powerful Wind Turbine Stands Complete.

This is the first paragraph.

With the final blade in place, the SG 14-222 DD prototype has become the world’s largest and most powerful turbine to be installed, taking the mantle from GE Haliade-X 14 MW prototype operating in the Port of Rotterdam, the Netherlands.

Note.

  1. This is a 14 MW turbine, that can be boosted to 15 MW.
  2. Kincardine Wind Farm has 5 x 9.5 MW and 1 x 2 MW turbines.
  3. Northern Horizons is talking about a 10 GW floating wind farm to the North-East of the Shetlands, that will use 20 MW turbines. The turbine visualisation on their web site, looks like it could be a WindFloat or similar technology.

How many 20 MW turbines does it need to carpet the seas around the UK?

Conclusion

Kincardine Wind Farm may be the world’s largest floating wind farm, but this won’t hold true for long.

  • I can see various designs of semi-submersible platforms being developed, that will be able to support the world’s largest wind turbines.
  • They will also be able to operate in the world’s deepest waters far out to sea.
  • Northern Horizons talk of 20 MW turbines may sound ambitious, but I suspect that turbine engineers are already thinking bigger.

Offshore wind and its turbines will both have a huge future.
