There are a number of green gases that will be key to the energy transition of the islands we serve. We will publish our Green Gas plan in 2023 which will outline how we will phase these into our supplies on our journey to Net Zero. This is an area of great pace of innovation and change, so our plans will reflect that.
BioGas and BioLPG are a naturally occurring and renewable source of energy, resulting from the breakdown of organic matter, often food-waste. These gases can be added and mixed into our existing gas supplies and utilised by existing appliances without any modifications. The greater the levels of BioGas in our supply, the lower the carbon intensity. We are working on a plan to source or generate them and distribute to our customers by 2024 (or before if realistic) and build up the proportion over time.
Green Hydrogen is generated from renewable energy and water to produce a gas that produces almost zero greenhouse gas emissions when combusted. To introduce hydrogen, a number of challenges need to be solved: we need hydrogen-ready boilers, hydrogen-ready networks, regulation changes and a steady surplus of renewable energy to make the gas.
We will work with partners in the UK and Europe to tap into developments in these areas, but it looks likely that our first hydrogen supply will not be until after 2025. Due to several factors, the Isle of Man is likely to be the first island to receive hydrogen supply.
Gas as the fuel of transition
Gas is not like other hydrocarbons. The EU and the UK see fossil gas as a strategic and key transition energy source. There is agreement that gas will play a pivotal role throughout the transition due to its versatility, its wide range of applications, and low local environmental impact and carbon intensity.
Fossil gas is unique in that:
1It is significantly cleaner and more efficient than oil and coal
2It has the lowest carbon impact in its transportation
3It can be mixed with other low-carbon gases (or green gases) to further decrease carbon emissions
