What is biomethane, and how is it different from biogas?
Biogas is the raw gas that comes off anaerobic digestion of organic material: sewage sludge at a wastewater treatment plant, food and process waste, animal waste, or the decomposing waste in a landfill. It is typically 50% to 65% methane, with the rest mostly carbon dioxide plus moisture and trace contaminants such as hydrogen sulphide and siloxanes.
Biomethane is biogas that has been upgraded: the carbon dioxide, water and contaminants are removed until the gas is 95% to 99% methane. At that purity it behaves like natural gas, so it can be injected into the gas network, compressed as vehicle fuel, or stored and used on site. A biomethane plant is the equipment that does that upgrading.
Use the gas on site, or inject it into the network?
A site that produces biogas has two main ways to turn it into value, and Evo Energy Technologies supplies both:
- Generate electricity and heat on site with a biogas cogeneration plant. The raw biogas is treated and burned in a 2G engine, and the site uses the power and heat itself. This suits sites with a steady demand for both, such as wastewater plants, meat processors and piggeries.
- Upgrade the biogas to biomethane with an ETW biomethane plant and inject it into the gas network, or use it as renewable gas for processes that need gas rather than electricity. This suits sites that produce more gas than they can use, or that are close to a gas main and can earn more from renewable gas than from electricity.
The two are not exclusive. A plant can run a cogeneration engine on part of its gas to cover its own power and digester heating and upgrade the rest, and Evo's engineers model both options from the site's gas production data before recommending a path.
What the ETW biomethane plant delivers
- Purification capacity from 200 to 10,000 Nm3/h of raw biogas
- Methane concentration in the product gas adjustable from 95% to 99%
- Energy consumption as low as 0.14 kWh per Nm3, including pre-conditioning
- Plant availability above 99%
- Automatic adaptation to changing gas volumes and compositions, so the product gas stays within the purity and heating value the network requires
- Engineered in Germany and refined over more than a decade of operation
Frequently asked questions
Which sites can produce biomethane?
Any site with a reliable biogas supply: wastewater treatment plants with sludge digesters, landfills with gas capture, food and beverage manufacturers with organic waste digesters, and agricultural operations such as piggeries, dairies and feedlots.
Can biomethane be injected into the Australian gas network?
Yes, where the network operator accepts it and the gas meets its specification for methane content, heating value and contaminants. The ETW plant is designed to hold the product gas within those specifications automatically. Network connection and gas quality approval are handled with the local network operator as part of the project.
Is biomethane renewable?
Yes. It is made from biogas, which comes from organic material that would otherwise decompose and release methane to the atmosphere. Capturing and upgrading it displaces fossil natural gas.
Can a biomethane plant be added to an existing biogas site?
Yes. Biomethane upgrading is often added to a site that already captures biogas and either flares it or runs a cogeneration engine on it, to make use of gas that is currently surplus.
