Greenhouse gas removal programme wins £30million government funding
25 May 2021
Researchers across UK will investigate large scale removal of CO2 from atmosphere
Research teams across the UK will investigate the viability of five innovative methods of large scale Greenhouse Gas Removal (GGR) from the atmosphere, to help the UK reach its legislated Net Zero climate target by 2050.
The five different methods all have potential to remove greenhouse gases from the atmosphere but need to be better understood and proven at scale.
The project has funding for five years from UK Research and Innovation (UKRI) and is the UK Government’s largest-ever research programme to date. As well as the Greenhouse Gas Removal Demonstrators Programme, there will be a central Directorate Hub led by the University of Oxford.
The Oxford-led consortium, named CO2RE, has been chosen as the Directorate Hub to coordinate the national programme with a strong research function and the ability to liaise with the demonstrators, business, policymakers and public to evaluate a variety of approaches to removal. The Hub includes the Univeristy of Oxford, University of Edinburgh, University of Bristol, University College London, Imperial College London, University of Leeds and University of Manchester. The five demonstrators are led by Aberystwyth University, University of Exeter, University of Nottingham, University of Sheffield and the UK Centre for Ecology and Hydrology.
Unlike techniques to reduce emissions at source, GGR aims to capture and remove CO2 and other greenhouse gases already in the air. Achieving net zero requires dramatic reductions in emissions, but it also requires GGR. As the UK Government has set the goal of net zero emissions by 2050, and the COP26 climate negotiations take place in Glasgow in November this year, the CO2RE Hub will play a critical role in bringing together leading UK academics and provide flexible funding to help participants in the Greenhouse Gas Removal programme bridge gaps in research and engagement activities.
Professor Cameron Hepburn, from the University of Oxford, and the overall lead of the Directorate Hub said:
“Greenhouse gas removal is essential to achieve net zero carbon emissions and stabilise the climate. Alongside the need for much faster emissions reductions now, we also need to start pulling CO2 out of the atmosphere.”
The five Greenhouse Gas Removal Demonstrator projects will investigate:
- Management of peatlands to maximise their greenhouse gas removal potential in farmland near Doncaster, and at upland sites in the South Pennines and in Pwllpeiran, West Wales.
- Enhanced rock weathering - crushing silicate rocks and spreading the particles at field trial sites on farmland in mid-Wales, Devon and Hertfordshire.
- Use of biochar, a charcoal-like substance, as a viable method of carbon sequestration. Testing will take place at arable and grassland sites in the Midlands and Wales, a sewage disposal site in Nottinghamshire, former mine sites and railway embankments.
- Large-scale tree planting, or afforestation, to assess the most effective species and locations for carbon sequestration at sites across the UK, including land owned by the Ministry of Defence, the National Trust and Network Rail.
- Rapid scale-up of perennial bioenergy crops such as grasses (Miscanthus) and short rotation coppice willow at locations in Lincolnshire and Lancashire.
Dr. Isabela Butnar, Academic Lead and Senior Researcher in Bioenergy Systems
explains the role of the Institute for Sustainable Resources at UCL:
Practically all pathways to net zero by 2050 and a maximum 1.5oC global warming by 2100 require extensive use of technologies that remove greenhouse gases from the atmosphere. UCL is pleased to be a core consortium partner in CO2RE, the UK Research Councils’ Hub for greenhouse gas removal (GGR) research. One of UCL’s roles will be to coordinate the development of a robust evaluation framework for GGR technologies, which will be absolutely necessary if these technologies are to be trusted permanently to remove carbon dioxide from the atmosphere.”
