Hydrogen Produced at Scale Using Biological Process Combining Carbon Capture

In a significant development for the renewable energy sector, the Biorenewables Development Centre (BDC) at the University of York has broken new ground by successfully producing hydrogen at scale through a biological process. This pioneering project has also managed to capture carbon dioxide emissions, a crucial step towards reducing atmospheric pollution.

Hydrogen has long been heralded as a cleaner alternative to fossil fuels like oil and gas, particularly for heating and certain modes of transport. However, traditional methods of hydrogen production can still release carbon dioxide, undermining its environmental benefits. The new technological advancements led by the BDC offer a solution to this challenge.

Dubbed the H2Boost project, the initiative is in collaboration with the University of Leeds and is backed by the UK government’s £1bn Net Zero Innovation Portfolio (NZIP).

The project employs a method known as dark fermentation, which involves converting everyday organic waste into biohydrogen. This innovative approach not only creates hydrogen but also captures by-products to generate additional energy, effectively ensuring minimal waste.

Anaerobic digestion, complemented by the use of cultivated algae and bacteria, plays a significant role in capturing emissions, further enhancing the environmental credentials of this process. Officials and industry insiders believe the technology could significantly advance the UK’s net-zero objectives, especially in the decarbonisation of the transport sector. Projections suggest that low-carbon hydrogen technologies could satisfy up to 35% of the UK’s energy needs by 2050.

The H2Boost project is supported by a consortium of organizations, including Aardvark EM, AB Agri, CM90, Cyanocapture, MyGroup, NNFCC, Qube Renewables, and Ramboll, in a collective effort to create a commercially viable and sustainable process for hydrogen production from organic waste.

The initiative forms part of the Department for Energy Security and Net Zero’s aspirations to develop leading green industries, ensuring energy security, efficient markets, and greater energy efficiency.

BDC programme operations manager Penny Cunningham said: “Successfully demonstrating integrated hydrogen production with carbon capture represents a significant technical breakthrough for the H2Boost project.”

“Our novel approach to producing clean hydrogen from waste while removing CO2 is not only technically feasible but also holds significant promise for large-scale sustainable energy solutions in the future.”
