New Baltic Sea Interconnector On Horizon As Lithuania, Latvia, and Germany Plan Cross-Border Link
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Lithuania, Latvia, and Germany are planning a joint offshore interconnector that would enable electricity trading between the Baltic countries and Germany and allow for the integration of up to 2 GW of offshore wind capacity in Lithuania and Latvia
These first two paragraphs add more detail to the article.
The energy ministers of the three countries signed a joint declaration of intent on 18 February, paving the way for the development of the Baltic-German PowerLink interconnector, which would, in addition to electricity trading and offshore wind capacity integration, also enable the expansion of onshore renewable energy capacity.
The Lithuanian, Latvian, and German transmission system operators (TSOs) – Litgrid, Augstsprieguma tīkls and 50Hertz – agreed to assess the feasibility of the hybrid electricity interconnection.
As Germany, has the following connections under development in the West.
- AquaVentus to Aberdeen, Humberside, Denmark, Norway and The Netherlands.
- NeuConnect to the Isle of Grain In England.
- GriffinLink, which is an offshore link to England.
The Germans seem to be putting themselves at the centre of an energy distribution system, that has the capability to stabilise European and UK electricity for thousands of years. Especially, if the network grows to include more countries.
This paragraph says this about the Baltic-German PowerLink project.
The Baltic-German PowerLink project concept developed by Litgrid, Augstsprieguma tīkls, and 50Hertz includes a 2 GW, approximately 600 kilometres long hybrid offshore connection, with the connection point in the Baltic States planned to be on the border between Lithuania and Latvia. The exact location is to be determined after technical studies.
Note.
- The interconnectors may be long, but they are not longer than anything built successfully before in European waters.
- The UK and the Island of Ireland are well-linked.
- There would appear to be no need for challenging projects like the Morocco-UK Power Project
I suspect that Germany will get the energy it needs and the British Isles will get a nice little earner.
If Europe is generating large amounts of wind and solar energy with its variable output it will need lots of energy storage.
What Countries Have The Terrain For Pumped Storage Hydro In Europe?
I asked Google AI and received this answer.
Key countries with ideal, high-elevation terrain and significant existing or planned capacity include:
Alpine Region (The Heart of European Pumped Storage):
Switzerland: Extremely high capacity due to steep, mountainous landscapes and significant water sources, hosting the world’s oldest working pumped storage plant.
Austria: Heavily mountainous, it is a major player in PSH expansion and modernization.
France: Home to one of Europe’s largest, the Grand Maison hydroelectric power station.
Italy: Holds high capacity with numerous planned projects.
Germany: Strong existing infrastructure.
Southern Europe:
Spain: Features some of Europe’s largest plants (e.g., La Muela/Cortes-La Muela).
Portugal: Significant recent investment in large-scale projects like the Tâmega complex.
Other Potential Areas:
Norway: High potential due to its mountainous, water-rich terrain.
United Kingdom: High project volume currently under construction.
Balkans & Central Europe:
Countries like Bulgaria, Romania, and the Czech Republic have suitable terrain for further development.
These countries benefit from significant hydraulic head (steep drop) and natural or artificial reservoir potential, making them ideal for storing energy for peak consumption hours.
Note.
- As expected, the Alpine region is Top of the League.
- The UK is holding its own despite its small mountains.
- There is a lot of potential to be developed.
But then Electric Mountain in Snowdonia is certainly at the top table of pumped storage systems despite being built in the 1980s.
What Countries Have The Terrain For Hydrogen Storage In Europe?
I asked Google AI and received this answer.
Key European countries with suitable geological terrain—specifically salt caverns and depleted gas fields—for large-scale, underground hydrogen storage include Germany, the Netherlands, Denmark, the United Kingdom, and France. Other significant regions for storage potential include Spain, Hungary, and Austria, which are developing porous storage facilities.
Key Regions & Terrain Types:
Salt Caverns (North-Western Europe): Germany, the Netherlands, Denmark, France, and the UK have substantial salt deposits suitable for creating caverns, identified as cost-efficient for large-scale storage.
Depleted Gas Fields (Porous Rock): The Netherlands, Germany, and parts of Central/Southern Europe (Spain, Hungary) have significant capacity in existing porous storage, particularly in the North Sea region.
Specific Projects: Germany (Uniper’s Krummhörn project), Netherlands (HyStock), and France (HYPSTER at Etrez) are active, with Spain and Denmark emerging as major hydrogen hubs.
Capacity Potential: The Netherlands, for instance, holds massive potential (35-60 TWh) due to its offshore and onshore depleted fields.
Salt cavern projects, which offer high-deliverability storage, are heavily concentrated in the North-Western European industrial corridor.
I was lucky enough have a tour of ICI’s salt mine in Cheshire, when I worked there in the 1960s and I remember these facts from those days.
- There was enough salt in the ground under Cheshire to last several thousand years.
- Most salt was extracted from boreholes, for making chlorine using electrolysis and the Castner-Kellner process.
- Hydrogen was a by-product and much of it was mixed with coal gas to raise steam for the works.
The same technique used to make boreholes to extract the salt, is used to hollow caverns in the salt to store gases like hydrogen.
Once, when they were digging salt out of the salt mine at Winsford, a worker broke into an unmarked borehole and ICI nearly lost the mine because of the water rushing in.
Two stories stand out from the rescue of the mine.
- There was a need for dry clothes for all the workers, so ICI took a truck to Marks & Spencer in Northwich and emptied it of anything they might need. I was told the story enriched with plagues of locusts.
- A Ford Transit was found to have travelled a few thousand miles underground in axle deep salt slurry. Rather, than scrap it and buy another, it was offered back to Ford, who were delighted to swap it for a new one. I heard that Ford said, that the accelerated corrosion research would have taken many years, if done on the roads.
Always think out of the box.

There will only be one winner in this new round of the ongoing spat between Trump and the wind industry, that he hates so much – the 1.3 million active lawyers in the United States,which is a figure from according to Google AI.
Rolls-Royce Supplies mtu On-Board Power Generators For Baleària’s Electric Ferries On The Route Between Europe And Africa
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the three bullet points.
- Eight mtu emergency power generators ensure power supply on two fully electric, emission-free fast ferries operated by the shipping company Baleària
- Over 11,000 kW total output as backup for electric operation
- To be used on the route between Tarifa (Spain) and Tangier (Morocco) starting in 2027
These are the first two paragraphs.
Rolls-Royce’s Power Systems division is supplying a total of eight mtu emergency power generators for two fully electric fast ferries belonging to the Spanish shipping company Baleària. From 2027, the ships will cover the 18 nautical miles between Tarifa in Spain and Tangier in Morocco using electric power, thereby opening up the first “green corridor” between Europe and Africa.
The project is considered a milestone for CO2-neutral mobility at sea and is supported by an international network of partners consisting of shipping companies, shipyards, port authorities, energy suppliers, and other companies.
Note.
- The route is only 18 nautical miles.
- Each ferry can accommodate 804 passengers and 225 cars.
- The ferries have a cruise of 26 knots.
- The project is considered a milestone for CO2-neutral mobility at sea.
- Each ship will have an installed power of 11,000 kW on both electric and diesel.
- They should go into service in 2027.
I know little about ships, but these look to be the business and I can see them sneaking silently into ports everywhere.
But AI might, so I’ll ask a few questions.
How Will Baleraia’s New Fast Ferries Handle Rough Weather?
This was replied.
Baleària’s new fast ferries, such as the Eleanor Roosevelt and Margarita Salas, incorporate advanced stabilization and hull systems designed to improve comfort and reliability in adverse sea conditions. However, as with all maritime transport, sailings can still be cancelled or delayed due to severe weather for safety. reasons.
It certainly looks like the Spaniards are going for it.
Japanese Company Takes Part In Spain’s Floating Wind Demonstration Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Japan’s Electric Power Development, also known as J-Power, has joined the WHEEL floating offshore wind demonstration project in Spain.
These three paragraphs add more details.
The WHEEL demonstration project is led by the Madrid-headquartered company Esteyco. WHEEL will feature one turbine installed three kilometres off the eastern coast of Gran Canaria, Spain.
Through this project, J-Power aims to acquire knowledge in the manufacturing, assembly, installation, and operation of floating offshore wind power, contributing to the development of floating offshore wind projects in Japan and abroad, the company said.
A floating offshore wind turbine, with a capacity of 6.17 MW, will be constructed and tested using WHEEL, which combines the advantages of barge-type foundations and spar-type foundations.
There is a visualisation of the WHEEL project in the linked article.
Conclusion
I like the concept of WHEEL.
In Norwegians Developing Monopile Foundation For 100-Metre Depths, I write about my involvement with a company called Balaena Structures in the 1970s, who were trying to develop a reusable oil and gas platform. I have a feeling, that WHEEL and the Balaena have dynamic and floating properties in common.
DOE Announces 7 Awards To Cut Heliostat Costs
The title of this post, is the same as that of this article on Solar Paces.
I haven’t talked about heliostats much before and can only find these two posts; one about Australia and one about Spainspain
- ‘Unique’ Solar-Storage Solution Providers Plot 300MW / 3.6GWh Australia Project
- Spanish Govt Approves Energy Storage Strategy, Sees 20 GW In 2030
I feel it is good that the Americans are backing this technology.
These are a summary of the projects.
- SunRing: Advanced Manufacturing and Field Deployment: This project by Solar Dynamics LLC and partners will develop processes to maximize cost-competitiveness, performance, and reliability of Solar Dynamics’ existing SunRing heliostat design.
- HELIOCOMM: A Resilient Wireless Heliostats Communication System: This components-and-controls project by the University of New Mexico will model a resilient wireless communication system based on the principles of integrated access and backhaul (IAB) technology, entropy-based routing, dynamic spectrum management, and interference mitigation.
- An Educational Program on Concentrating Solar Power and Heliostats for Power Generation and Industrial Process: This project by Northeastern University will develop an educational program focused on concentrating solar power (CSP) and heliostats for power generation and industrial processes.
- Demonstration of a Heliostat Solar Field Wireless Control System: Solar Dynamics LLC, with partners Remcom and Vanteon Corporation, will carry out a project aimed at demonstrating the reliable operation of a wireless heliostat solar field control system using commercially available products and developing analytical tools to de-risk the large-scale deployment of the wireless technology to solar fields with tens of thousands of heliostats.
- Twisting Heliostats With Closed-Loop Tracking: This project will design, manufacture, and test a new type of heliostat and study its application for high-concentration CSP.
- Digital Twin and Industry 4.0 in Support of Heliostat Technology Advancement: The Tietronix project aims to leverage technologies from the Fourth Industrial Revolution (Industry 4.0) to enhance the CSP industry and achieve the cost reduction experienced by other industries that have already adopted such advancements.
- Robotic-Assisted Facet Installation (RA-FI): Sarcos Technology and Robotics Corp., in collaboration with Heliogen, will investigate the feasibility of a novel mobile robotic system capable of supporting the installation of mirror facets onto a heliostat.
Governments and institutions and individuals with money should support this sort of research and development.
Spain Launches App To Show If Men Shirk Housework
The title of this post is the same as that of this article in The Times.
This is the first paragraph.
Spain has announced plans to introduce an app that promises to address the gender imbalance of housework by getting users to log the hours they spend on chores.
At least it’s a free app!
IberBlue Plans To Install 18 MW Floating Wind Turbines On Spanish-Portuguese Atlantic Ocean Border
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
IberBlue Wind has announced plans to build two floating wind farms on the North Atlantic border between Spain and Portugal. The projects, planned to be installed off the coasts of Baixo Miño in Pontevedra and Viana do Castelo, would have a total of 109 turbines of 18 MW and a combined capacity of up to 1.96 GW.
These two later paragraphs also describe two other offshore wind farms being developed by IberBlue in Spain and Portugal.
Since then, IberBlue has already announced two floating offshore wind projects of 990 MW capacity each, one in Spain and one in Portugal.
In Spain, the joint venture is developing the Nao Victoria floating wind farm, planned to be built off the coasts of Cadiz and Malaga, in the Alboran Sea, the westernmost part of the Mediterranean Sea. The wind farm is planned to comprise 55 floating wind turbines, also with a nominal output of 18 MW per turbine.
It does look as if IberBlue have defined that for the seas around the Iberian peninsular, 18 MW floating wind turbines will be their standard.
As these giants could have a 20 % increase in capacity compared to 15 MW turbines for the same number of turbines, I think that developers will seriously look at the costs and performance pf the larger turbines and could install them more widely.
BP Launches Plans For Low-Carbon Green Hydrogen Cluster In Spain’s Valencia Region
The title of this post is the same as that of this press release from BP.
These are the four bullet points.
- Aims to make Valencia region a leader in green hydrogen production
- Cluster to include world-scale green hydrogen production at bp’s Castellón refinery of up to 2GW of electrolysis capacity by 2030
- Supports transformation and decarbonization of the refinery, together with tripling biofuel production
- Transformation of Castellón could see bp invest up to €2 billion
This is the first paragraph.
bp today launched the green hydrogen cluster of the Valencia region (HyVal) at its Castellón refinery. Led by bp, this public-private collaborative initiative is intended to be based around the phased development of up to 2GW of electrolysis capacity by 2030 for producing green hydrogen at bp’s refinery.
It certainly is a big hydrogen-friendly project and is a roadmap of how to decarbonise an oil refinery.
This massive commitment to hydrogen makes me more certain, that bp’s offshore 50 MW wind farm twenty miles from Aberdeen, is designed to produce hydrogen for the granite city.
Are bp putting together a strategy to bring hydrogen to the world?
After all hydrogen is the only zero-carbon fuel, that can directly replace fuels like natural gas, diesel and many hydrocarbon fuels in a large number of applications.
X1 Wind’s Floating Prototype Delivers First Power Offshore Canary Islands
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
X1 Wind has announced that its floating offshore wind turbine prototype delivered first power to PLOCAN’s smart grid in the Canary Islands, Spain.
The article is based on this news item from X1 Wind, which is entitled X1 Wind’s X30 Floating Wind Prototype Delivers First kWh, which starts with these two paragraphs.
X1 Wind has announced today (MARCH 07) that its X30 floating wind prototype, installed in the Canary Islands, successfully produced its first kWh.
The milestone marks the world’s only floating wind platform currently installed with a TLP mooring system, which dramatically reduces the environmental footprint and improves compatibility with other sea uses. It further heralds Spain’s first floating wind prototype to export electricity via a subsea cable.
Note.
- TLP is short for tension leg platform, which is described in this Wikipedia entry.
- The TLP Wikipedia entry contains a section, which describes their use with wind turbines.
- TLPs have been in use for over forty years, with the first use in the Hutton field in the North Sea.
- TLPs work well for water depths of between 300 and 1,500 metres.
I also suspect there’s a lot of experience from the oil and gas industry around the world about how to deploy TLPs.
The X1 Wind news item also has this paragraph.
The novel X30 platform is equipped with a specially adapted V29 Vestas turbine and ABB power converter. Another key design feature, developed through the EU-backed PivotBuoy Project, combines advantages of SPM and TLP mooring systems. The proprietary SPM design enables the floater to ‘weathervane’ passively and maximise energy yields, with an electrical swivel ensuring electricity transfer without cable twisting. The TLP mooring system also dramatically reduces the seabed footprint, compared to traditional designs proposing catenary mooring lines, minimizing environmental impact while maximizing compatibility with other sea uses, in addition to its suitability to move into deeper waters.
SPM is short for single point mooring, which is described in this Wikipedia entry, where this is the first sentence.
A Single buoy mooring (SrM) (also known as single-point mooring or SPM) is a loading buoy anchored offshore, that serves as a mooring point and interconnect for tankers loading or offloading gas or liquid products. SPMs are the link between geostatic subsea manifold connections and weathervaning tankers. They are capable of handling any tonnage ship, even very large crude carriers (VLCC) where no alternative facility is available.
Note.
- The use of the weathervane in both paragraphs.
- If an SPM can handle a VLCC, it surely can handle a well-designed floating structure with a wind turbine mounted on top.
- I suspect that an SPM used for a wind turbine will be much simpler than one used to load or unload a gas or oil tanker.
As with TLPs, I also suspect there’s a lot of experience from the oil and gas industry, from around the world about how to deploy SPMs.
It looks to me, that X1 Wind have used the proven attributes of SPMs and TLPs to create a simple mooring for a wind turbine, that is designed to align itself with the wind.
X1 Wind Are Open With Their Technology
Today’s news item from X1 Wind also links to two other useful documents.
- X1 Wind Adaptation Of A Vestas V29 Turbine To Downwind Configuration
- X1 Wind Successfully Installs Floating Wind Platform In Spain
They are certainly open with their information.
The news item, also includes this video.
Thoughts
These are some thoughts.
Capacity Factor
The capacity factor of this wind turbine could be an interesting figure.
As the turbine constantly will turn to be downwind, this should maximise the amount of electricity produced over a period of time.
Tetrahedrons
The design is effectively a tetrahedron.
Alexander Graham Bell knew a lot about the properties of tetrahedrons and invented the tetrahedral kite.
This document details Bell’s involvement with tetrahedrons and says this.
Bell found the tetrahedron to have a very good strength to weight ratio.
Put more simply this means that an object is structurally very strong but at the same time very lightweight.
So X1 Wind’s design is probably extremely strong for its weight.
Large Turbines
X1 Wind’s prototype uses a wind turbine of only 225 KW.
Manufacturers are building 15 or 16 MW turbines now and talking of 20 MW in the next few years.
Given the strength of the tetrahedron, I wonder, if it will be possible to build a PivotBuoy, that is capable of hosting a 20 MW wind turbine?
Conclusion
Although it appears radical, it uses proven technology to generate power in an innovative way.
In some ways the thinking behind the design of this floating technology, is a bit like that of Issigonis in his design for the first Mini, where he took proven technology and arranged it differently to perform better.
Gondan Shipyard Launches Another Hydrogen-Ready CSOV
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Gondan Shipyard has launched another commissioning service operation vessel (CSOV) it is building for the Norwegian shipowner Edda Wind at its yard in Figueras, Spain.
Increasingly smaller ships are being built hydrogen-ready, so they can be converted to zero-carbon, when the technology is developed.
Over the last couple of years companies like Cummins, JCB and Rolls-Royce mtu have developed diesel engines that can be converted to hydrogen engines.
Cummins talk of agnostic engines, which are identical from the cylinder head gasket down and what is above it, can make the engine, diesel, hydrogen on natural gas powered.
