Belfast biohydrogen reactor to open in 2025

A new type of biohydrogen reactor fuelled by sustainable biomass and waste is set to come online in Belfast Harbour after receiving £4.9m in government funding.

Developed by Belfast-based CATAGEN, the ClimaHtech BIOHGEN Biohydrogen Reactor is claimed to deliver hydrogen at scale, using less energy than electrolysis. According to CATAGEN, it produces hydrogen from a feedstock of waste biomass which is readily available both in the UK and Ireland and does not displace the growing of crops for food. The process also produces CO2 as a byproduct, which the company claims can be used to displace the fossil CO2 that many industries rely on today.

The technology has already been demonstrated at prototype scale in Northen Ireland, providing low carbon hydrogen to the Mannok Cement Plant in Ballyconnell. This new tranche of funding from the UK Department for Energy Security and Net Zero (DESNZ) will enable the company to build a full-scale demonstrator in Belfast’s famous harbourside Titanic Quarter.

“This funding award allows us to move into our next phase of development for the ClimaHtech BIOHGEN system, recruiting more engineers as we accelerate our journey to clean and decarbonise the air,” said Dr Andrew Woods, CEO and co-founder of CATAGEN.
