In September 2025, the UK government announced a significant plan: to invest over £1.1 billion (approximately $1.49 billion) in collaboration with the industry to drive the green upgrade of the maritime sector and create new growth opportunities, aiming to solidify its position as a "global maritime hub".

As early as March this year, the UK Maritime Department released the "Maritime Decarbonisation Strategy," which sets clear decarbonization targets of 30% reduction by 2030, 80% reduction by 2040, and achieving zero emissions by 2050. It also envisions the UK becoming a green energy superpower. This injection of funds is one of the key implementation measures of the UK government's "Maritime Decarbonisation Strategy," with the funding divided into two parts: £700 million from private investments, primarily for major ports and industrial sectors in the UK, and £448 million from public funds focusing on decarbonization measures in the shipping industry.

The UK's Maritime Decarbonisation Office (UK SHORE) is a core supporting body for decarbonization technologies, playing a crucial role in projects such as zero-emission shore power systems at facilities like Cammell Laird shipyard, Aqua Superpower's charging network project, and Smart Green Shipping's FastRig wing sail project. It has already provided funding support totaling £240 million for over 200 projects, with the additional funding focusing on research and development projects for clean technologies such as electric propulsion, hydrogen, ammonia, and methanol.

In terms of major ports and industries in the UK, Peel Ports Group plans to invest £3 billion in its Liverpool, Hunterston, and Great Yarmouth ports, with an additional £10 billion reinvestment over the next five years. The group has advanced multiple projects, including the construction of port-related warehouses, steel and metal processing facilities, and significant upgrades to key ports. NatPower Marine intends to collaborate with Peel Ports Group to establish a green maritime corridor connecting Ireland and the UK, investing £25 billion in the construction of shore power systems.

From advancing clean technologies to upgrading port infrastructure and fostering cross-industry collaboration, the UK is striving to lead the decarbonization process in the global maritime sector through substantial investments. This initiative not only helps the UK gain an advantage in the global competition for green shipping but also provides core competitiveness to solidify its position as a "global maritime hub" and build itself into a green maritime energy superpower.
