Biorenewables Development Centre awarded additional £5m for biohydrogen project
This is funded by the Net Zero Innovation Portfolio (NZIP) that has been awarded by the UK government's Department for Energy Security and Net Zero.
H2Boost aims to produce biohydrogen for the UK transport sector by integrating an advanced oxidation and enzymatic pre-treatment technology of bio-based feedstocks, conversion to bio-hydrogen by dark fermentation (DF) and down-stream processing of by-products via anaerobic digestion, microbial CO2 capture and storage.
Building on the work of phase 1, under-utilised, low-value feedstocks will be subjected to different pre-treatment conditions to improve biohydrogen yields and reduce the residency time of nutrient-rich streams in DF.
The fermentation by-products, namely anaerobic digestion digestate, will be used as substrates for algal propagation and anaerobic digestion to achieve a closed-loop system for enhanced biomethane yield and carbon capture and storage (CCS).
This multi-step process aims to create a technology that is financially viable and environmentally sustainable.
Input from the supply chain, market engagement, techno-economic and life cycle analysis will demonstrate process environmental and commercial sustainability.
The work undertaken by the consortium will contribute to the decarbonisation of the passenger and long-haulage transport sector which contributed to 16% of 2019 domestic GHG emissions. The growing demand for hydrogen to meet the UK net-zero ambitions will rely on processes such as those deployed by the H2Boost consortium.
The project combines expertise from academia and industry with support from a panel of external advisors on feedstock pre-treatment, fermentation, microbial analysis, and downstream processing. The integrated process developed by H2Boost partners is intended to offer a novel reliable source of UK-produced low-carbon biohydrogen and high-value products with market applications such as biofertiliser and biofuels to help to address the use of high volume waste streams in generating biohydrogen.
"We are delighted to be awarded phase 2 funding to further develop biohydrogen for the UK transport sector, commented Deborah Rathbone, bioscience innovation team manager at Biorenewables Development Centre.
"Working with our ten partners, the University of Leeds, Greenthread Solutions, Qube Renewables, Aardvark EM, WSP, Cyanocapture Ltd, The Maltings Organic Treatment Ltd, AB Agri, NNFCC and CM90 Ltd, we have a real opportunity here to make a difference as the H2Boost objectives align with the UK ambition of reaching net-zero by 2050 with low carbon hydrogen-based technologies providing up to 35% of energy requirements."
