European biomethane project investments

In mid‑July 2026, the MBG Mittelständische Beteiligungsgesellschaft Baden‑Württemberg committed €1 million to a biomethane processing plant in Ravensburg, Germany. The project integrates biogas upgrading, agri‑photovoltaic installations and battery storage to create a regional value chain that supplies high‑purity methane to a local pharmaceutical company and recycles carbon dioxide for nearby greenhouse production.

Two weeks later, Bankinter Investment and Plenium Partners acquired Italy’s BG Holding, which operates two biogas plants slated for conversion to biomethane. The transaction received regulatory clearance in Portugal and is expected to bring renewable gas to roughly 6,000 households while cutting annual CO₂ emissions by 18,000 tonnes. Together, these developments illustrate a broader European push to expand biomethane production through private investment, cross‑border acquisitions, and integrated renewable‑energy infrastructure.
