Scottish Western Isles Ferry Transport using Hydrogen (SWIFTH2)

As part of the Scottish Government’s carbon emission reduction target, transport emissions will need to be decarbonised by 37% by 2032. A big part of decarbonising transport will be identifying solutions that reduce emissions from marine transport.

Wood is involved in one such project. The Scottish Western Isles Ferry Transport using Hydrogen (SWIFTH2) project aims to explore the viability of producing hydrogen through electrolysis powered by onshore wind on the Western Isles and to power two ferry routes. The constrained grid connection on these islands limits the deployment of renewable energy sources despite the excellent resources. Hydrogen production could act to balance the renewable energy generation on the islands, thus enabling further expansion and produce green fuel for the ferry transport that these communities are reliant on.

Among other services, the work carried out by Wood as part of the project includes:

  • Model the existing ferries energy demand profile.
  • High-level assessment of land-side hydrogen and grid infrastructure.
  • Assessment of renewable energy yield.
  • Financial modelling.

The results suggest that if the Stornoway to Ullapool is converted to hydrogen, it could result in emission reduction of 21,815 tonnes of CO2 equivalent annually. Additionally, it would improve the air quality, enable growth of local renewable energy projects and have a positive impact on the local economy.
