Chemical engineers lead efforts to unblock UK hydrogen use

Project comes as UK sets out legislation to boost energy security with hydrogen, CCS and fresh oil

CHEMICAL engineers are investigating how the UK could increase its use of hydrogen and alternative liquid fuels as part of the nation’s commitment to net zero by 2050.

Tim Mays from the University of Bath will lead a research consortium that aims to map and solve the research challenges blocking wider uptake of low carbon fuels in the UK. Mays is a Professor of Chemical Engineering and Director of the Institute for Sustainable Energy and the Environment at Bath. He said: “A thriving, low carbon hydrogen sector is essential for the Government’s plans to build back better, with a cleaner, greener energy system. Large amounts of low carbon hydrogen and alternative liquid fuels such as ammonia will be needed, which must be stored and transported to points of use. Much research is required, and we will work collaboratively across multiple disciplines to help meet these challenges.”

The team will focus on the potential of fuels to decarbonise transport; electricity generation; domestic and industrial heating; and high CO2-emitting industries such as cement, fertilisers, glass, and steel. According to the University of Sheffield, a consortium partner, these areas account for up to 90% of UK greenhouse gas emissions, demonstrating the project’s “enormous” potential impact.

Using the theory of change

Mays’ team will engage stakeholders and use a theory-of-change process to map the greatest research challenges and potential solutions. Theory of change is a rigorous, participatory process in which groups and stakeholders identify the conditions they believe have to unfold to allow long-term goals to be met.

The consortium said that there is strong engagement from industry stakeholders and high-profile project partners including ITM Power, the Health and Safety Executive, Siemens Energy, and Scottish Hydrogen and Fuel Cell Association.

Co-investigators include Rachael Rothman, Professor of Sustainable Chemical Engineering at the University of Sheffield, and Shanwen Tao, Professor of Chemical Engineering & Sustainable Processes at University of Warwick.

Sara Walker, Professor of Energy at Newcastle University, is leading a second project focusing on the role of these fuels in the net zero transition, in providing connectivity and flexibility across the energy system. Walker’s work will analyse the landscape, challenges, and demand for low-carbon fuels to identify viable investment priorities. It is expected to deliver a fundamental shift in critical analysis of hydrogen’s role in the energy landscape.

Walker’s team will work with stakeholders to gain new perspectives on future hydrogen pathways.

Over six months, the research coordinators are expected to build high-impact, multidisciplinary, multi-site teams, with the aim of developing longer-term research alliances, as well as two parallel national centres of excellence at Bath and Sheffield. One centre will be focused on research challenges, and the other on systems integration.

The Engineering and Physical Science Research Council (EPSRC) is providing the hydrogen projects with a total of £615,000 (US$769,800) over the six-month research period, which began on 1 April.

Kedar Pandya, Director for Cross-Council Programmes at EPSRC said: “Over the next six months, the hydrogen research coordinators will work across the UK to build an understanding, and galvanise expertise, in research and systems integration.

“The focused, multi-stakeholder plan they create will support the consideration of hydrogen as a key component of the UK’s energy mix and inform EPSRC’s future plans for an integrated, ambitious research and innovation programme working across the hydrogen value chain and its major use
