Renewable Gas

Renewable gas is produced through the anaerobic transformation of organic raw materials, which includes waste from green sources, households, agriculture, agri-food industries, and landfill waste. It therefore provides a highly competitive, low-cost transport fuel alternative. Renewable gas is an easily storable fuel that can be used in the same way as natural gas, allowing you to maintain your current business processes wherever natural gas is utilized.

Through methane capture and purification, biogas upgraded into renewable gas can be utilized in applications such as heating, generating electricity and as a transport fuel (Liquified or compressed Biomethane), further reducing our dependence on natural gas and other fossil fuels.

With existing gas infrastructure networks in place, biomethane will be of vital importance during the transition of our energy system to renewable sources. The future of biomethane looks bright.

At STX we help supply meet demand by trading renewable gas, offtaking feedstocks, and by developing new renewable gas projects.
