What is green gas?

Green gas, also known as renewable natural gas or biomethane, is a sustainable and renewable form of natural gas that is produced from organic materials such as food and agricultural waste, wastewater, and landfill gas.

Green gas production involves capturing and processing biogas, which is a methane-rich gas produced through the decomposition of organic matter in anaerobic conditions. The biogas is then purified to remove impurities such as carbon dioxide and water vapor, resulting in a high-purity methane gas that is chemically identical to natural gas.

Green gas can be used in the same way as fossil natural gas to generate electricity, heat buildings, and power vehicles, but with significantly lower greenhouse gas emissions. In fact, green gas production and use can help in reducing carbon emissions, improving air quality, and promoting circular economy practices by utilizing organic waste that would otherwise be sent to landfill.

Some countries have already established incentives and policies to support the production and use of green gas, such as feed-in tariffs, tax credits, and renewable energy certificates, to help transition towards more sustainable and eco-friendly energy sources.
