Ballymena could host UK’s first grid-scale hydrogen-to-power system

Ballymena could become the site of Northern Ireland’s first grid-scale hydrogen-to-power (H2P) system, as BS Holdings Ltd confirms plans to partner with POWERHOUSE ENERGY GROUP PLC in a zero-emission energy project aimed at supporting the National Grid.

The proposed development, which is dependent on support from the Department for Energy Security and Net Zero, would combine renewable electricity with hydrogen production to provide back-up power when wind generation drops and battery storage is depleted.

Developers say the initiative represents a significant step in advancing zero-emission hydrogen-to-power technology in Northern Ireland this decade.

Hydrogen-to-power system to support grid stability

Under the plans, BS Holdings Ltd will combine its efforts with POWERHOUSE ENERGY GROUP PLC to produce both fuel and electricity. Working alongside an electrolyser manufacturer, the project aims to track renewable power output as it fluctuates while continuing to generate hydrogen.

The two energy sources would be combined to power what is described as the first hydrogen-to-power plant at scale in Northern Ireland.

In modelling, the test bed is expected to deliver almost 2MWs of grid power — enough to supply approximately 350 properties continuously.

The system is designed to provide electricity in the critical period between wind generation falling and conventional gas or coal-fired steam turbines coming online. Developers say it would take over supplying the National Grid when battery reserves are depleted.

The project also incorporates what is described as a “Penta” output system, producing five streams: high-grade heat, low-grade heat, water, electricity and cooling. If all energy outputs are utilised, overall efficiency could approach 90%, according to modelling.

A UK-built system with export ambitions

Project leaders state that the Ballymena development would be the first UK-built hydrogen-to-power grid-scale system, assembled entirely using UK manufacturers and based in Northern Ireland.

They describe the initiative as part of a wider effort to strengthen domestic energy security at a time when governments face competing offers from major international firms in the hydrogen and renewable energy sectors.

If successful, the system could position Northern Ireland as a centre for hydrogen-to-power innovation, with export potential.

Ballymena’s strategic role in hydrogen infrastructure

The proposed location in Ballymena places the town at the forefront of emerging hydrogen infrastructure in Northern Ireland.

A second phase, subject to successful demonstration of the initial technology, could see the creation of Northern Ireland’s first public-facing renewables-only filling station. This facility would supply both hydrogen fuel cell electric vehicles (FCEVs) and battery electric vehicles (EVs) using renewable energy-generated electricity or hydrogen.

Developers envisage the site allowing manufacturers such as BMW and Toyota to display hydrogen and electric vehicle fleets. It could also provide refuelling capability for Translink and Wrightbus fleets, alongside serving heavy goods vehicle operators across the Ballymena area.

Skills, training and employment opportunities

Beyond energy generation, the project could have implications for local employment and skills development.

Plans include the creation of highly skilled roles in hydrogen, electrical, electronic and mechanical engineering, with collaboration anticipated with Northern Regional College to support new training programmes tailored to the hydrogen sector.

For Ballymena, the development would not only represent a technological milestone but could also reinforce the town’s established engineering and manufacturing base while contributing to Northern Ireland’s zero-emission energy ambitions.
