Scotland's New Sustainability Hub Makes the Switch to Wind

Plans are under way to transform 350 acres of the former coal-fired power plant at Hunterston in Scotland into a cutting-edge renewable energy hub. 

This ambitious redevelopment project is set to support the UK’s renewable energy infrastructure and accelerate the transition to sustainable energy sources.

The site will feature advanced technologies like Liquid Air Energy Storage (LAES) to efficiently store and release excess energy, a solution deemed superior to traditional battery systems. 

Highview Power (HVP), the company leading the project, has announced its vision to establish the world’s largest LAES facility at Hunterston — a significant milestone in renewable energy innovation.  

Hunterston’s sustainable future  

Hunterston is on track to become the heart of the UK’s renewable energy sector. 

The LAES facility alone is expected to generate enough energy to power 650,000 homes for nearly 13 hours — a reliable backup for renewable energy sources like wind and solar. 

The construction phase will create 1,000 jobs, providing a much-needed economic boost to the local community. 

Hunterston is predicted to draw £3.5bn (US$4.4bn) in investments, creating more than 5,000 jobs in the renewable energy sector in the long term. 

XLCC plans to manufacture high voltage direct current (HVDC) cables in Hunterston, a technology that enables efficient electricity transmission over long distances — playing a vital role in connecting power grids globally.  

The facility includes an undersea energy cable factory, which has already received £9m (US $11.4m) in funding from Scottish Enterprise to continue its £1.4bn (US$1.8bn) development. 

XLCC’s undersea energy cable factory is 90% already under option — a term meaning to give a buyer the exclusive right to purchase a property within a set time frame with no obligation to purchase — connecting the nation with solar farms in north Africa.

This development highlights Hunterston’s critical role in enhancing the UK’s energy security through international renewable energy collaborations.  

Peel Ports promise

Peel Ports operates several terminals in the region, including one at Hunterston, and is also investing in the site’s transformation. 

The company has committed up to £150m (US$190m) to establish Hunterston as a premier renewable energy hub, with a particular focus on offshore wind energy.  

James McSporran, Port Director of Peel Ports Clydeport, says: “The idea that the UK lacks the necessary infrastructure for a just transition is simply a myth. 

“Scotland particularly already has the reputation, infrastructure and talent to support renewables projects, meet national environmental aspirations, create long-term green jobs and unlock local and national economic growth opportunities.”  

James emphasises that achieving this vision requires businesses to invest heavily while policymakers must create favourable conditions. 

He adds: “We currently estimate the consenting process for the Hunterston redevelopment will be complete by early 2025, followed by two years of construction.”  

Hunterston’s redevelopment aligns with Scotland’s net zero goals, positioning it as a key player in supporting the UK’s clean energy future — only if policymakers establish the right investment conditions.

Highview Power’s LAES

Highview Power’s LAES technology underpins this transformation, offering a scalable and clean energy storage solution.

Unlike traditional batteries, LAES relies on liquefied air to store surplus energy, providing storage from six hours to several weeks — ensuring a more resilient energy grid and reducing reliance on fossil fuels.  

The company’s strategy focuses on four main objectives:  

• Flexible demand: When the supply of renewable energy outstrips demand excess output is captured, relieving pressure on the grid, cutting wastage and reducing the need for costly and inefficient curtailment programmes
• Long duration storage (LDS): The storage solution uses the power of air to stockpile and reserve renewable energy until it’s needed
• Responsive generation: When demand exceeds supply, 100% clean energy is re-generated, solidifying the shift from fossil fuels to wind and solar
• Strengthened stability: Demand for stability services is set to grow significantly because of the retirement of gas generation, the company provides cost-effective grid stabilisation, reduced reliance on fossil fuels, energy security and cheaper and more stable energy costs.

The Hunterston project represents a significant step towards a sustainable energy future, demonstrating Scotland’s potential as a leader in renewable innovation.
