Green gas (biomethane) is produced from “fresh” organic matter taken from landfills or biogas plants through a process called anaerobic digestion. This process cleans, dries, and compresses biogas biomethane into a higher calorific value “green” product permitting it to be added into the existing natural gas network.

Biomethane is a naturally occurring gas and is chemically identical to natural gas (methane), however what makes it renewable is it’s origin from fresh organic matter and because it can be readily produced worldwide. Unlike the fossil fuel ‘methane’ which is 20 times more potent than carbon dioxide and is produced over millions of years, buried deep underground in certain geographical locations.

Organic matter from which biomethane is produced would release methane into the atmosphere if left to decompose naturally, the decomposition process also creates other harmful greenhouse gases such as nitrous dioxide.

Biomethane production eliminates the release of these harmful gases into the atmosphere by preventing exposure of the decomposing organic matter to the air. Burning natural gas (methane) for power generation or heat, creates carbon dioxide and other greenhouse gases, so by reducing our dependency on fossil fuels,  green gas reduces the emissions of these greenhouse gases.

Biomethane production utilises waste matter such as sewage, food , organic material from brewing industries and agricultural waste which also improves hygienic conditions and quality of life in rural areas, and reduces the risk of water pollution.

By converting the carbon dioxide and carbon monoxide fraction of green gas to methane during the production process, the renewable gas potential of raw biogas is roughly doubled.

The increase in our demand for green gas and decreasing our demand for firewood will help preserve forests which in turn helps lower concentration of carbon dioxide in the atmosphere as the trees absorb carbon dioxide while releasing pure oxygen.

Time is running out, the planet’s carbon budget is finite and everyone needs to pull together. By utilising green gas for electricity generation, space heating, process heating and in transportation we can all help make the massive, unprecedented and sustained shift away from fossil fuels and become greening organisations for a positive change for the climate.

Every kWh of green gas is tagged and tracked to certify its source, supply and consumption. Renewable green gas contracts are available as 100% green gas, or blended with natural gas in 50% or 25% mixes to suit all requirements.
