Carlton Power agrees partnership with Scotland’s Superglass to develop green hydrogen project in Stirling

UK manufacturer of glass mineral wool insulation Superglass has entered into a strategic partnership with Carlton Power to supply it with green hydrogen for its manufacturing facility at Stirling, Scotland.

The partnership agreement will support the development of Carlton Power’s proposed Stirling Green Hydrogen scheme and reduce Superglass’ reliance on natural gas.

The Stirling Green Hydrogen scheme is Carlton Power’s first scheme in Scotland.  Subject to planning and final designs, it will be similar to Carlton’s three other hydrogen projects that were shortlisted by the UK Government (March 30th) to receive financial support through the government’s Hydrogen Business Model/Net Zero Hydrogen Fund.  The UK Government is using these multi-million-pound programmes to encourage the growth of the hydrogen economy in Scotland and across the UK.

Carlton Power is an established independent energy infrastructure development company with offices in Edinburgh and Stokesley in north Yorkshire. Its Stirling Green Hydrogen scheme will provide Superglass and potentially other energy-intensive users in the area (for example, those with transport fleets) with hydrogen to fuel their operations.

Secured demand for hydrogen at Stirling will underpin the initial development of a 10 MW (megawatt) electrolyser, expected to produce approximately 1000 tonnes of green hydrogen every year - reducing 7000 tonnes of greenhouse gas emissions which is equivalent to taking around 160 trucks off Scotland’s roads every year.  Carlton Power anticipates hydrogen demand in the area to increase significantly in the near term and will develop the project in such a way that additional capacity can be added.  The hydrogen will be produced by an electrolyser using electricity that is generated from sources of renewable energy, primarily wind and solar power. 

The scheme is to be located at Polmaise, close to Superglass’ manufacturing plant on the Thistle Industrial Estate in Stirling.  The Superglass plant, which completed a £37 million upgrade in 2019, produces around 60,000 tonnes of glass wool insulation annually and employs 200 people.

The scheme, subject to planning and financing, will see sustainable hydrogen fuel being produced at scale, creating opportunities for businesses in Stirling and the surrounding area to make Net Zero plans with hydrogen in mind.  The hydrogen hub facility will support the growth of renewable electricity generation by utilising it to produce and store hydrogen at times when renewable output is high, but demand is low. 

“We’re delighted to be working with Superglass to bring forward our Stirling Green Hydrogen hub; it will help Superglass achieve its sustainability goals and support Scotland’s decarbonisation strategy” said Eric Adams, Hydrogen Projects Director at Carlton Power.  “It is critical that projects such as this are brought forward to support investment by local companies in their operations that can reduce their carbon emissions.”

Stirling is part of a portfolio of green hydrogen schemes being developed by Carlton Power and, subject to planning consent and a final investment decision within the next 12-18 months, it would be owned by the Green Hydrogen Energy Company (GHECO), Carlton’s new joint venture company with Schroders Greencoat (announced on May 23rd).

“Carlton Power’s experience in hydrogen and wider energy project development in the UK is first-class, and so we are very pleased to be working with them to develop the Stirling scheme” added Theresa McLean, Chief Executive of Superglass. “Superglass’s operations are already very energy efficient – our glass wool insulation is made from up to 84 percent recycled glass and is estimated to save around 300 times the amount of energy used to manufacture it – but we know that we must do more. We need to make the transition from fossil-based fuels to hydrogen in order to cut our carbon emissions.  The Stirling Green Hydrogen scheme will be an important step forward for not only our company, but the community in which we operate.”

Within GHECO, Carlton Power is managing the development, construction and operation of current and future green hydrogen projects, with Schroders Greencoat leading the financing of the projects and leveraging its UK renewable energy expertise.  Schroders Greencoat is a specialist investment manager dedicated to the renewable energy infrastructure sector in the UK and Europe.

Carlton Power, Superglass and GHECO would like to see the green hydrogen hub in operation in 2026 but its construction is contingent on securing local planning and financial support from the UK Government.

Over the next 12-18 months, Superglass and Carlton Power will work together on the various economic, technical, and engineering aspects of the scheme, as well as consultations with local and national stakeholders, including the Scottish Government.  They will also work together to obtain grant funding and operational financial support from the UK Department of Energy Supply and Net Zero (DESNZ).  A submission to DESNZ will be made into the next Hydrogen Allocation Round (HAR2), scheduled to be launched in the final quarter of this year.
