The aim of the present study is to assess the techno-economic viability of integrating
biomethanation into power to gas systems in a real waste water treatment plant (WWTP) …

Biogas, which typically consists of about 50–70% of methane gas, is produced by anaerobic
digestion of organic waste and wastewater. Biogas is considered an important energy …

Liquid fossil fuels (1) enable transportation and (2) provide energy for mobile work platforms
and (3) supply dispatchable energy to highly variable demand (seasonal heating and peak …

Biogas produced from anaerobic digestion processes has been considered as an important
alternative to natural gas and plays a key role in the emerging market for renewable energy …

Storage options for increasing amounts of volatile energy supplied by renewable sources
are of growing interest. One promising concept is power-to-gas, where electrical energy is …
