Crown Estate’s Auction Of Seabed For Wind Farms Attracts Sky-High Bids

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

This is the opening paragraph.

An auction of seabed rights to build offshore wind farms around England and Wales has attracted frenzied bidding that could be worth hundreds of millions of pounds a year to the Treasury and the Queen.

I don’t find this surprising.

Bigger Seems Better Offshore

Wind turbine technology is getting better and much larger. It also seems that the new larger floating turbines are much more efficient and generate power for a greater proportion of the day.

My project management software helped to harvest North Sea Oil and I have been told by many in the industry, that North Sea Oil really took off when platforms and the equipment like cranes used to build them got truly enormous.

I feel, we could be seeing the same size effect happening as we harvest the wind!

Hydrogen And Wind Power

The latest development is not to generate electricity, but to use it in the turbine to generate hydrogen, which is then piped to the shore.

  • The UK Government is funding this technology in part with a grant to ITM Power.
  • I wrote about the technology in ITM Power and Ørsted: Wind Turbine Electrolyser Integration.
  • Existing gas networks can be reconfigured to bring the hydrogen to the shore.
  • Piping hydrogen costs less than cabling electricity.
  • Hydrogen networks are being built at several places in the UK, to fuel homes, power stations and industry like steel-making and petrochemicals.

Could all this explain Big Oil’s involvement?

Do they want to exchange fossil fuels for green hydrogen?

They certainly know how to distribute it.

Energy Storage

For my own investments, I’m looking at energy storage, where the UK has at least three promising new ideas, all of whom have had Government grants.

  • Gravitricity
  • Highview Power
  • ReEnergise

The Government has also indirectly-backed Cornish Lithium

  1. Very interesting for wealth funds, but, when do we get the free electricity and heating we were once promised from these “free” sources of power? At the moment energy costs are at least four times the cost of Coal produced energy. I remember when five shillings in the meter kept you going all day!

  2. Meanwhile, on the other side of the North Sea, Denmark has a plan:

    “Denmark approved a plan on Thursday to build the world’s first energy island in the North Sea that will produce and store enough green energy to cover the electricity needs of 3 million European households. The artificial island, which in its initial phase will be the size of 18 football fields, will be linked to hundreds of offshore wind turbines and will supply both power to households and green hydrogen for use in shipping, aviation, industry and heavy transport.” (Reuters, via gCaptain)

    • Thanks!

      It certainly seems to fit the bigger is better theory!

  3. Not looked into detail of Hywind but very interesting concept and i like the way they prebuild the whole turbine just offshore and tow it out to the wind site for connection to the ground anchors. I guess its still more expensive then conventional monopile turbines is what there are no more being built in UK but given the higher capacity factor it seems a no brainer to me we should be investing more in this technology. I do see Norway has committed to an 11 site array to power rigs on one of there oil fields using 8MW turbines.

  4. […] It seems to follow the bigger-is-better offshore principle, I talked about in Crown Estate’s Auction Of Seabed For Wind Farms Attracts Sky-High Bids. […]
