In 2014, the transport sector was responsible for 23% of total greenhouse gas emissions in the European Union (EU). During the same year, 13% of that sector's emissions came from the maritime segment, a number that is expected to rise during the coming years. The transport sector's share of renewable energy in 2014 was just 5.9%, mostly comprising biodiesel and bioethanol fuel. When we compare this to electricity generated in the EU from renewable sources, at 25.4%, it is clear that electricity generation is leading by a significant margin. Electrification is a solution that will help reduce the transport sector's reliance on hydrocarbonbased fuels. New energy infrastructures such as hydrogen refueling stations are needed to decarbonize the transport sector. This article describes the Island Hydrogen project, which introduced and tested new solutions to produce and use hydrogen as a fuel for vehicles and vessels.
