Using green hydrogen to supply island energy needs is the theme of several projects which Irish offshore communities and universities are involved in.
A consortium of Irish islands led by Kerry’s Valentia Island Co-op and Rathlin, Co Antrim is examining the feasibility of combining offshore wind with electrolyser technology to convert water to hydrogen.
The Aran islands are involved in this and several parallel projects, including work at NUI Galway (NUIG).
Researchers at the NUIG Ryan Institute Energy Research Institute are collaborating in a five-year project that will generate, distribute and use at least 300 tonnes of hydrogen per year produced from solar energy on the Balearic island of Mallorca.
The NUIG team involving Dr Pau Farràs Costa, Dr Rory Monaghan and Dr Thomas van Rensburg say it will reduce CO2 emissions by 20,000 tonnes per year.
The project will embed green hydrogen in the island’s whole energy system, from solar power generators which will produce the hydrogen, to gas grid operators which will distribute it and to bus operators, vehicle rental firms, homes, businesses and hotels using it for power, heat and mobility, they state.
The NUIG team will assess the economic impacts of the green hydrogen on Mallorca, as well as on other island communities involved in the project, including the Aran Islands.
“Green Hysland will be the first opportunity to demonstrate how green hydrogen holds the key to island decarbonisation and energy independence,” Dr Farràs Costa, of NUIG’s School of Chemistry, said.
Green Hysland - Deployment of a hydrogen ecosystem on the island of Mallorca is being supported with €10 million of European Commission funding, along with investments by partners of up to €50 million.
