3.1.3 Increasing interest in biomethane as a feedstock and energy carrier across industry sectors

Biomethane is gaining interest as an alternative to natural gas for medium and high temperature heat generation and as a feedstock and energy carrier in multiple industry sectors, either through using natural gas injected with biomethane, through integration of biomethane production in industry processes, or as a feedstock to produce high value chemicals.

Biomethane is gaining interest as a way to decarbonise the industry and power thermal generation sectors, either as an energy carrier when biomethane is injected in the natural gas grid, through integration of biomethane production in industry processes, or as a feedstock to produce high value chemicals.

  • Biomethane can be used as a substitute for natural gas in industrial applications and processes to produce high value chemicals (e.g. methanol production). This concept is gaining interest with early commercial applications.120
  • The food and feed producing industry that uses biomethane can integrate food and feed production with biogas and biomethane production onsite from food and feed waste and residues, through co-investment in biomethane production. This integrated process provides an organic waste management service and benefits from the availability of zero-cost feedstocks. This integration also increases the efficiency of processes by supplying onsite energy needs and reducing the CO2 footprint of industry. This application is in early commercial development—for example by Tesco Ireland.112
  • Biogas can be generated from waste sludge in the pulp and paper industry and can be used for low- to medium- grade heating within the process.122 This application is in a pre-commercial stage—e.g. the Effisludge project in Norway.123
  • Biogas and biomethane can be produced from wastewater sludge in municipal installations as indicated in section 2.1 with the sewage treatment plant in Amsterdam.
