The Mineral Products Association (MPA) has won £6m of government money to demonstrate the use of hydrogen and plasma technology to help reduce carbon emissions in cement and lime production.
The demonstration projects follow a government-funded feasibility study in 2019 which found that a combination of 70% biomass, 20% hydrogen and 10% plasma energy could be used to eliminate fossil fuel CO₂ emissions from cement manufacturing. The aim now is to test that theory.
The cement trials will take place at sites operated by Tarmac and Hanson Cement. The cement production trial comprises two demonstrations, one of electrical plasma energy and biomass fuel and the other of hydrogen and biomass energy, as alternatives to fossil fuels.
The UK lime production trials will take place at a site operated by Tarmac – demonstrating the applicability of hydrogen as an alternative to natural gas for lime manufacturing.
Both projects will share their results shared to their wider industries and supply chains, with the hope of maximising the environmental benefit of the technology. The MPA projects are forecast to be completed by the end of March 2021.
Minster for business, energy and clean growth, Kwasi Kwarteng, said: “Reducing emissions from homes and industry is a key part of our work to eliminate our contribution to climate change by 2050.
“This innovative project by MPA and its members is an exciting development and could make a significant impact on our net zero ambitions.”
Nigel Jackson, MPA chief executive, said: “This important award demonstrates MPA members’ commitment to collaborative research and innovation to meet the industry’s climate change objectives. We are proud to be able to facilitate this collaboration between our members and Government and it’s the latest example of our ongoing efforts to deliver our contribution to tackling climate change.”
Mike Eberlin, managing director of Tarmac’s Cement & Lime business said: “Securing this funding is an extremely positive step for our industry as we support the UK’s ambition of achieving net-zero carbon emissions by 2050. Collaborative working and embracing innovative technologies are key in our collective efforts to create a lower carbon, resilient built environment and we’re proud to be involved in such an important project which will help inform industry and government strategic plans on decarbonisation.”
Hanson UK CEO Simon Willis added: “Cutting carbon emissions is a key priority for us at Hanson and our parent company Heidelberg Cement Group is the first in the industry to commit to producing carbon-neutral concrete by 2050 at the latest.
“These BEIS-funded research projects could represent a significant step change in supporting the UK government’s sustainable development goals as it responds to climate change.”
