First Power At Scotland’s Largest Offshore Wind Farm

The title of this post, is the same as that of this press release from Seagreen wind farm.

These two paragraphs summarize the project and its start-up.

TotalEnergies and its partner SSE Renewables, has announced first power generation from the Seagreen offshore wind farm, 27km off the coast of Angus in Scotland.

The first turbine of a total of 114, was commissioned in the early hours of Monday morning. The aim is for the 1075 MW farm to be fully operational in the first half of 2023. The £3bn Seagreen project will be Scotland’s largest offshore wind farm and the world’s deepest fixed bottom wind farm as it is being developed in up to water depths of 59 meters.

It looks like 1075 MW cost £3billion, so I suspect it’s reasonable to say that offshore fixed-foundation wind farms cost about £2.79billion per GW.

The press release also says this about yearly output.

When fully operational, the site will produce around 5 terawatt hours (TWh) of renewable electricity per year, enough to power the equivalent of 1.6 million households.

That looks like an expected capacity factor of 53.1 %.

The Third Route To Zero-Carbon Transport

The two most common routes to zero-carbon transport are.

  • Battery-electric vehicles
  • Hydrogen fuel-cell vehicles

Note that most hydrogen-fuel cell vehicles also have a battery.

But I believe there’s a third route and that is the use of hydrogen in an internal combustion engine.

Earlier today, I wrote Rolls-Royce And AVK Provide Over 3.5 Gigawatts Of Emergency Power Capacity In The UK, which is based on a Rolls-Royce press release, with the same title.

This is an extract.

And this is said about the use of hydrogen.

Rolls-Royce is also currently developing its mtu gas engine portfolio for power generation so that the engines can run on hydrogen fuel in future, enabling a Net Zero energy supply. The company is also launching complete mtu hydrogen fuel cell solutions, that emit nothing but water vapor from 2025. This will enable CO2-free generation of emergency power for data centers and many other critical applications.

I certainly think, that they are going in the right direction.

Rolls-Royce mtu have a lot to lose, if their diesel engines that power trains, heavy equipment, ships and emergency power generators are replaced by other companies zero-carbon solutions.

  • Large investments will need to be made in hydrogen electrolyser and fuel cell production.
  • Some traditional factories making diesel engines will be closed and could this mean redundancies?
  • A lot of retraining of staff at both manufacturer and customer will need to be made.

But a traditional internal combustion engine, that runs on hydrogen or even both hydrogen and diesel makes the transition to hydrogen a lot less painful.

Other companies going this route include Cummins, Deutz and JCB.

Conversion Of Existing Diesel Engines To Hydrogen

Surely, if an equivalence hydrogen engine exists for all of their diesel engines, a company like Cummins or Rolls-Royce mtu can produce a sound engineering route to decarbonise some of their existing applications.

A classic application would be converting London’s Routemaster buses to hydrogen, which I wrote about in Could London’s New Routemaster Buses Be Converted To Hydrogen Power?

This was my conclusion in that post.

I believe from my knowledge of Cummins and the way they work, that they will come up with a hydrogen-based solution, that will replace the Cummins diesel in these buses with a zero-carbon engine.

If Cummins don’t then someone else will.

Whoever solves the problem of converting London’s new Routemasters to hydrogen will have one of the best adverts for their product, there has ever been.

After converting London’s thousand Routemasters, the engineers could move on to anything powered by a Cummins engine.

As this is a world-wide problem, I believe that the manufacturers of cars, buses, trucks and many other vehicles will offer zero-carbon solutions for their products, as it will be necessary for survival.

If you have just bought a new diesel BMW and your government says that in two years time, diesel will no longer be available, you’re up the creek without a paddle. But if BMW can convert it to hydrogen for a small fraction of the cost of a new electric equivalent, you have a more available way out.

Rolls-Royce And AVK Provide Over 3.5 Gigawatts Of Emergency Power Capacity In The UK

The title of this post, is the same as that of this press release from Rolls-Royce.

The press release starts with these two bullet points.

  • UK’s largest technology companies rely on emergency power solutions from AVK and Rolls-Royce
  • Focus on Net Zero solutions with sustainable fuels and fuel cells

And then this summary of the business in the UK.

Rolls-Royce has delivered 200 mtu emergency generators to AVK, UK’s leading provider of critical power solutions, in just three years. AVK has already installed and commissioned the majority across Europe, and in total has already provided more than 3.5 gigawatts of power to data centers, the financial, telecommunications and healthcare industries in the UK and Ireland.

AVK is now the largest supplier of emergency power solutions to data centers and the financial sector in the UK, and since signing the exclusive agreement with the Rolls-Royce business unit Power Systems, has been using only mtu brand emergency gensets.

The next two paragraphs describe the business in more detail.

These are some points from these paragraphs.

  • Data is now the ‘fourth utility’ required by all.
  • The European colocation data center market is expected to grow at a compound annual growth rate of 13.1 percent from 2021 to 2028.
  • The most important European markets for data centers are Frankfurt, London, Amsterdam, and Paris, where demand is highest.
  • AVK provides, installs and maintains systems over their entire service life.
  • Emergency power systems based on  mtu diesel systems ranging from 825 to 4,000 KVA are tailored to customer needs.
  • AVK has been using mtu engines for emergency power systems for over 20 years.

Rolls-Royce And AVK seem to have developed a nice little earner.

Net Zero Emergency Power Solutions

The last section talks about net-zero solutions for generators and emergency power.

This is set about sustainable fuels.

Sustainability already plays a major role for data center operators. As a result, interest in alternative fuels has grown and AVK is increasingly providing support and guidance on switching from using diesel to HVO (Hydrotreated Vegetable Oil). mtu Powergen engines from Rolls-Royce can be used unchanged for sustainable EN15940 fuels, such as HVO; no engine hardware or software modifications are required with the same performance. Using HVO can significantly reduce CO2, nitrogen oxide and particulate emissions.

And this is said about the use of hydrogen.

Rolls-Royce is also currently developing its mtu gas engine portfolio for power generation so that the engines can run on hydrogen fuel in future, enabling a Net Zero energy supply. The company is also launching complete mtu hydrogen fuel cell solutions, that emit nothing but water vapor from 2025. This will enable CO2-free generation of emergency power for data centers and many other critical applications.

I certainly think, that they are going in the right direction.

  • Data center operators are said to want sustainability.
  • Other users of emergency power will probably want the same.
  • A full range of solutions is offered.

Hopefully, it will bring more sales, as the market size increases.

First Ever Gravity Green Energy Storage System Set For North Yorkshire Town

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

These paragraphs give an outline of the project.

Plans to create the UK’s first below ground gravity energy storage system have been unveiled in North Yorkshire.

Scottish energy storage firm Gravitricity is to apply to Ryedale District Council with its plan for a facility at East Knapton in Ryedale on the site of the former Knapton gas generator.

If completed, it could store up to four megawatt hours (4MWhs) of electricity – sufficient to power more than 9,000 homes for an hour.

It looks like the system will have an output of 4 MW.

This Google Map shows the two villages of West and East Knapton.

Note.

  1. The A64 road between Malton and Scarborough going across the map.
  2. Scarborough and the coast is about fifteen miles to the East.
  3. The Third Energy site in the North-East corner of the map.

This second Google Map shows the Third Energy site in more detail.

Note.

  1. The substation and a power line in the North-East corner of the map.
  2. The 42 MW Knapton Generating Station used to be on this site and it was powered by local gas wells.

Third Energy have now called the site Knapton Energy Park and it now has a web page, which has this mission statement.

Third Energy is developing the former Knapton Generating Station into the Knapton Energy Park. The energy park will house multiple sources of power generation and energy storage. The aim of the project is to pay a part in the development and generation of renewable energy systems in North Yorkshire, and contribute to making the UK Net Zero by 2050.

This paragraph talks about weights.

One of our technology partners has also received government funding to conduct feasibility studies for a pilot project at Knapton which would utilise suspended weights to store energy as an alternative to the traditional battery storage technologies. This project will be developed through 2022 onwards.

It looks like Gravitricity has planted an acorn in Yorkshire.

The Third Energy web site is worth an explore. This is the mission statement on the home page.

At Third Energy our aim is to be at the forefront of North Yorkshire’s transition from fossil fuels to sustainable energy. Our team are proactively playing a part in innovative energy solutions and energy development; transforming our facilities into a multi-purpose energy park and research centre.

I particularly like this page, which is entitled Plug & Abandon.

This is the outline of their P % A philosophy on the page.

As wells near the end of their life cycle they must be decommissioned and the land returned to its original state. Unfortunately, the current P&A practices of the oil and gas industry are cost prohibitive, resulting in delays to abandonment (as companies attempt to avoid the high cost), and poor abandonment practices that may be harmful to the environment.

Fortunately, there are solutions to this problem. Our ambition is to use new and innovative technologies to P&A the wells in a more effective and sustainable manner, and first to extend the period our wells may service the community by re-purposing them for geothermal energy.

Can they really convert abandoned gas wells into geothermal energy sources?
