Biomethane, a sustainable and carbon neutral renewable gasContact us
What is renewable gas (biomethane)?
Biomethane is a carbon-neutral renewable gas made from farm and food waste through a process known as anaerobic digestion.
Biogas is initially produced through the breakdown of organic material (feedstock) by micro-organisms in large oxygen-free tanks (anaerobic digesters) into biogas and digestate. This process also occurs naturally in nature as organic wastes and residues decompose releasing methane into the atmosphere. To be injected into the gas network, this biogas must then be upgraded to biomethane and meet the quality standards as required by Gas Networks Ireland.
Biomethane, began flowing into the gas network in 2019 and is the first step to a cleaner energy future. It can reduce emissions across key sectors of the economy including heating, industry, transport and power generation, while also supporting the decarbonisation of the agri-food sector.
This renewable energy is structurally identical to natural gas and can be used in exactly the same way through the existing infrastructure, boilers and appliances, meaning homeowners and businesses will be able to transition to this sustainable energy source and play their part in progressing Ireland towards a cleaner energy future, without changing a thing.
Connecting biomethane producers
Gas Networks Ireland has a pivotal role to play in supporting Ireland’s transition to a net zero energy system. One of our key roles is to provide connections onto the network for biomethane producers. We facilitate the injection of the renewable gas biomethane into the gas network via two methods. A direct connection where a pipeline extension will be constructed to connect a biomethane plant to the network. Where a pipeline is not viable, the second option is to transport the biomethane by truck to a central grid injection facility, where it will then be injected into the gas network.
Please download our biomethane connections guide to learn more about the steps producers must take to connect and inject biomethane into the gas network.Learn more
Biomethane producers handbook
This biomethane producers handbook is a comprehensive technical guide that provides detailed instructions and information on the production of biomethane. It includes detailed explanations on the different types of biomethane production processes, the various components and technologies that are used, and the safety and regulatory considerations for biomethane production. This handbook is an invaluable resource for those interested in understanding and producing biomethane.Read more
Renewable gas in Ireland today
By gradually replacing natural gas with renewable gases, such as biomethane and hydrogen, Gas Networks Ireland aims to deliver a net-zero carbon gas network by 2050. Learn more about some of the key developments in the industry to date that will support reduce emissions across a number of key sectors, including those that are traditionally difficult to decarbonise, including heating, agriculture, industry, transport and power generation.
