Macquarie Capital, advisory, capital markets and principal investment arm of Macquarie Group, completed the acquisition of a majority stake in BioCow, a producer and innovator in the UK biogas industry. Financial terms were not disclosed. 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. “We have followed the development of anaerobic digestion in Europe for several years, looking for the right operating partner to scale this carbon neutral energy technology. We are excited to work with BioCow to develop its platform and contribute to the UK’s energy transition,” Patrick Ottersbach, Macquarie Capital Managing Director.
