“Biomethane is one of the most attractive segments of the energy transition for investors,” was the message sent to the market by Goldman Sachs just a few days ago. The firm has launched its newly formed Verdalia Bioenergy in Spain as part of its commitment to biomethane.

Biomethane (also known as “renewable natural gas") is a biogas from which the carbon dioxide and other contaminants have been removed. As a result of that purification process, the biomethane has the same characteristics as natural gas and can be injected into the grid. Biomethane production thus helps increase the proportion of green gases in our gas consumption, with benefits for the energy transition and the reduction of greenhouse gas emissions.
