H100 Fife

H100 Fife is our pioneering plan for a world-first green hydrogen heating network.

Central heating is responsible for up to a third of the UK’s greenhouse gas output: a challenge that must be solved if we are to meet the legally-binding net zero targets set by the UK Government and Scottish Government. Switching carbon-emitting natural gas for hydrogen, which doesn't produce carbon when it burns, is one of the ways that we can keep homes and businesses warm and safe while making ground in the fight against the climate emergency. 

The project

On the east coast of Scotland, our H100 Fife project aims to lay the foundations for this change while giving residents in the local area the opportunity to be at the leading edge of the low-carbon economy.

If our proposals are approved by Ofgem, we’ll build a world-first hydrogen network in Levenmouth. In the project’s first phase, the network will heat around 300 local homes using clean gas produced by an electrolysis plant, powered by the Offshore Renewable Energy Catapult’s nearby offshore wind turbine.  

The project would be the first of its kind to employ a direct supply of clean power to produce hydrogen for domestic heating – putting Levenmouth at the forefront of the clean energy revolution.

The system will be designed and built to ensure the same high safety and reliability standards expected from the current gas system. An on-site storage unit will hold enough hydrogen to ensure supply won’t be disrupted during even the coldest weather conditions.  

Clean energy combination

The emergence of offshore wind power as a large-scale source of clean energy is a key part of the hydrogen growth puzzle. It provides the scale necessary to generate large amounts of clean power needed for electrolysis – the process that creates hydrogen.

When powered by renewable energy, the generation and burning of hydrogen produces no carbon, making it the most effective, scalable way of providing heating while fighting climate change. It’s a clean energy combination that could put Scotland and the UK on track to hit net zero by 2045 and 2050 – and it all starts here, in Levenmouth.

Information for residents

H100 Fife will also play an important insight-gathering role into customer appetite and interest toward hydrogen and low-carbon heating solutions. 

The project will give people in Levenmouth the opportunity to be at the forefront of research into hydrogen heating systems. Eligible households can participate on an opt-in basis, meaning they will have the choice to switch to hydrogen, or remain with their existing natural gas supply. A proposed demonstration facility will allow customers to see and experience hydrogen appliances in a home-like setting prior to opting in. 


If our funding bid is successful, we'll be ready for construction to begin in 2020/2021. We’ll keep the local community in Levenmouth informed throughout development, and if the project comes to fruition, we’ll invite customers to get involved later in 2021. A five-year fully operational phase is planned from 2022/2023 ahead of heat policy decisions expected in 2023/2024. 

Gas Goes Green

H100 Fife is part of Gas Goes Green, the industry blueprint for cutting out carbon emissions. We’re working in partnership with the Energy Networks Association (ENA), National Grid, Cadent, Northern Gas Networks and Wales & West Utilities on a number of groundbreaking innovation projects aiming to develop a safe, smart gas system that delivers clean heating to homes and businesses.
