  • Upgrade for Biogas

    Biogas facilities are important drivers for the energy transition, yet, for many operators, they are no longer profitable. Conversion to biomethane can make such facilities more flexible and energy efficient ─ as well as opening up new business segments to the operators. Researchers at the Landshut University of Applied Sciences and the Weihenstephan-Triesdorf University of Applied Sciences have developed just such a process. Germany is scheduled to be generating 55 to 60 per cent of its electrical power from renewable energy sources by 2025 – currently it is around a third. However, photovoltaic systems only achieve their full capacity during the day in summer, and wind energy plants are usually only viable in exposed areas. The power demand during the dark winter months outstrips the production capacity of renewable sources. To some extent, biogas plants can compensate for these fluctuations and help to secure power continuity.
