In this report the potential use of CO2 in biorefineries to produce e-fuels, biochemicals or animal feed was investigated. In addition, the potential for enhancing plant growth in a vertical farming set-up was explored. Key findings were that there was considerable potential for a biorefinery based approach to CO2 utilisation and this was economically viable when co-located and combined with related activities. Vertical farming was a potential route to sequestering significant amounts of emitted CO2 and again was economically viable and could displace significant amounts of imported food. Both the biorefinery and vertical farm approaches were most financially viable as an integrated system such as with an AD plant and/or hydrogen production.
