Nel Hydrogen Electrolyser AS has received a purchase order for a 5 MW alkaline water electrolyzer from SGN for the world's first 100% hydrogen-to-homes heating network on the east coast of Scotland.

The 5MW alkaline electrolyzer is a fully redundant system and the contract includes installation and commissioning, as well as a service and maintenance contract. The electrolyzer will deliver up to 2,093 kg/day of green hydrogen at 30 barg to SGN's H100 Fife project in Levenmouth, Scotland.

The project is the first ever 100% hydrogen network of scale supplying green hydrogen from electrolysis to end users for the purposes of heating and cooking. The system will be powered by a nearby offshore wind turbine and grid electricity. The newly built hydrogen gas distribution network will supply up to 300 households initially with zero carbon heat, however both the electrolyzer and network have been sized to have the capacity to supply up to 900 homes as part of the planned future expansion of the H100 Fife project. 

The H100 Fife project is a groundbreaking demonstration in evidencing the role that hydrogen can play in decarbonizing heat as alternative to natural gas. SGN is one of the UK's largest gas distribution network companies, operating across Scotland, southern England and in Northern Ireland and is supplying gas to 5.9 MM homes and business.
