Macquarie Capital Principal Finance (Macquarie) has completed the acquisition of BioCow, a leading producer and innovator in the UK biogas industry.

BioCow uses anaerobic digestion to create energy from agricultural waste, by producing biomethane which can be used to heat homes and businesses and as a green transport fuel.

BioCow will use the investment from Macquarie to expand its existing operations in Cambridgeshire, as well as to support the completion of the UK's first biomethane injection point into the national transmission grid. This gas connection is a part of a pilot project with National Grid that aims to develop innovative solutions to reduce the time and cost of connecting to the high-pressure national transmission grid.

Macquarie's investment comes amid growing demand for green gas, providing institutional capital to a sector known for its operational and supply chain complexity. Biogas will play an important role in the UK's future energy mix, helping to lower the carbon impact of domestic heating and agricultural processes, as well as to improve the UK's energy security. Macquarie will use its renewable energy and infrastructure expertise to help BioCow seize this opportunity and provide capital as a catalyst to the growth of the business.
