Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment she has made of the potential impact of the current level of port and bunkering infrastructure on the uptake of e-fuels by UK-operating vessels; what steps the Government is taking to help increase the domestic (a) production and (b) supply of e-fuels for maritime transport; and what steps her Department has taken to help increase investment in port and bunkering infrastructure.

The Government provides the port sector with the right regulatory environment it needs to support investment, providing targeted support where there are clear public benefits, such as decarbonisation. In September 2025 the Government announced a further £448 million to the UK SHORE research programme, the biggest ever Government investment in commercial maritime across the UK. In addition, the Government is working with the National Wealth Fund, which has committed at least £5.8 billion of its capital to five sectors, including ports.

The Government has not conducted an assessment of the impact of an uptake in e-fuels on the current level of port and bunkering infrastructure in the UK, however we are taking action through policies set out in the Maritime Decarbonisation Strategy.

This Strategy includes a range of fuel scenarios, underpinned by a maritime emissions model, illustrating the varying ways in which the UK domestic maritime sector could transition from traditional fuels, such as heavy fuel oil, to zero and near-zero GHG emission fuels. Additionally, we intend to publish a consultation on a domestic maritime fuel regulation later this year which will help set the direction of UK maritime fuels policy and reduce uncertainty for the sector.
