Power-to-gas technology aims to cost-effectively and efficiently store renewable energy in the gas grid
for a longer period of time, while transitioning to a climate-neutral gas grid. Methane with its high
calorific value (36 MJ m-3), serves as a promising candidate for this process, doubling as a fundamental
chemical for industrial applications. Catalytic methanation stands as a well-established method for this
conversion; however, its reliance on high reaction temperatures (200 to 400°C) and expensive metal
catalysts render it energy-intensive and economically burdensome. An emerging alternative is biological
methanation utilizing archaea, enabling operation at lower temperatures (50 to 60°C). Additionally, the
adoption of bubble columns over continuous stirred tank reactors presents another energy-saving
improvement.
