Surrey University secures biofuel development funding

A new University of Surrey project is attempting to "revolutionise" the bioenergy market with the development of fast growing, soil-less, farming techniques.

In recent years the viability of soil, long term, has been called into question. The UN, this month, intensified their campaign warning of the soil fertility crisis and the ramifications on food security and development of bio-energy.

The soilless cultivation technology has been awarded £4m from the Department for Business, Energy and Industrial Strategy (BEIS).

Surrey’s project will develop an aeroponics system. It involves the cultivation of plants with no soil. This approach will use only water and nutrients to grow bioenergy trees, known as short rotation coppice willow for energy generation.

Dr Zoe M Harris, project lead from the University of Surrey, said: “If we are serious about meeting our climate targets, the UK will need to plant vast amounts of bioenergy sources and do so quickly. Having enough stock to ramp up planting to 720,000 hectares by 2050 represents a significant and undervalued bottleneck in the supply chain. Our innovation allows us to grow willow faster, with a higher yield on a smaller land footprint than traditional fields.

Along with optimising the technology, this project will see the research team investigate whether their soilless technology can be used for other crops such as hazel, forestry and the popular energy grass, Miscanthus. These advances will be important for other bioenergy crops and to assist the government’s tree planting targets to support reafforestation and rewilding.

Professor Bob Nichol, University of Surrey’s Executive Lead on sustainability and Pro-Vice-Chancellor and Executive Dean of the Faculty of Engineering and Physical Sciences, said: “Everyone here at the University of Surrey is deeply passionate about ensuring we set the world on a better trajectory when it comes to sustainability – that’s why we have just launched a university-wide Institute of Sustainability. Such an innovative solution to real-world problems is something we want to cultivate and encourage through the new institute. We also need to be sustainable as a University, and I’m impressed at how our research and innovation can help our campus achieve that goal.” 

The University of Surrey is working with both academic and industrial partners including: Rothamsted Research, UK Urban AgriTech, LettUs Grow, Aberystwyth University, Forest Research, National Institute of Agricultural Botany (NIAB), NMC2, Glideology and CapitalAgri.

Energy Minister, Greg Hands, added: “Accelerating home-grown renewables like biomass is a key part of ending our dependency on expensive and volatile fossil fuels. This £37 million of government investment will support innovation across the UK, boosting jobs whilst ensuring greater energy security for years."
