Eine Studie des EWI zeigt, dass neue Gasheizungen kurzfristig wirtschaftlicher sein können als Wärmepumpen, aber langfristig Gaspreis-Unsicherheiten bestehen. In Mehrfamilienhäusern sind Wärmepumpen bereits jetzt kostengünstiger. Das Angebot an Biogas ist entscheidend für die zukünftige Preisentwicklung.
India’s military is exploring alternative energy sources amid surging oil and gas prices caused by supply disruption from the Iran war, a trend that analysts say is set to accelerate among other Asian countries heavily dependent on energy imports. According to local media reports, the Indian army plans to get biogas stoves to replace natural gas-fired appliances for cooking. It is also exploring the use of green fuels for army vehicles and administrative work, as well as solar and wind power for...
Across much of India, an energy crunch caused by the Iran war has prompted long queues for cooking gas cylinders. That is not a problem for Gauri Devi. On a stove with blue flames, she flips a chapatti flatbread, burning biogas produced from cow dung – an alternative fuel helping ease pressure on supplies. “It cooks everything,” the 25-year-old said in her courtyard kitchen in Nekpur, a village in Uttar Pradesh, about 90km (55 miles) from New Delhi. “If the pressure goes down, we let it rest for...

Families in Maharashtra's Kolhapur district are using biogas units to convert organic waste into cooking fuel. This initiative provides a stable alternative to LPG, though the program faces challenges due to funding delays and subsidy issues.
Das bayerische Start-up Reverion stattet Biogasanlagen mit Hochtemperatur-Brennstoffzellen aus, die einen Wirkungsgrad von 74,2 Prozent erreichen - zehn Prozentpunkte besser als konventionelle Kraftwerke. Die reversiblen Festoxid-Brennstoffzellen können überschüssigen Strom aus erneuerbaren Quellen in Wasserstoff oder Methan umwandeln und speichern. Trotz des Potenzials, bis zu 200 Terawattstunden erneuerbares Methan ins Gasnetz einzuspeisen, sind erst vier Anlagen in Betrieb. Hauptprobleme sind fehlende Netzanbindungen und die Unsicherheit durch das Auslaufen der EEG-Förderung.
