Portsmouth delivers Sea Change and sustainability

After signing the Portsmouth Green Partnership Charter in November 2022, delivering the Sea Change project reaffirms the port’s commitment to play its part in a sustainable future for the city and to reduce its impact on the local community.
This project will design, build and operate a shore power system across the three busiest berths at Portsmouth International Port. “Sea Change has the potential to revolutionise the UK’s maritime sector, and further establish Portsmouth International Port’s [PIP]reputation as a living laboratory of green technology with industry-leading sustainability credentials,” explains Andrew Williamson, head of cruise & ferry, PIP.
Brittany Ferries is already running two new LNG-electric hybrid ships, shore power-ready ships to and from the port. With shore power available at the port, they will be able to charge their batteries and run on battery power when manoeuvring through Portsmouth harbour, improving air quality and supporting the industry-wide shift to zero-emission shipping.
Providing shore power will reduce harmful emissions and improve air quality around the port. PIP estimates that the system will avoid up to 20,000 tonnes of CO2e per annum from 2027, the equivalent to the annual carbon footprint of around 2,500 UK households or making 11,111 round trips by plane from London to New York.
When it comes to cruiseships, onshore power supply will be available at berth 2, with a mobile cable management system enabling connections for all shapes and sizes.
A consortium of academics, marine specialists and some of the UK’s most exciting technology SMEs have been brought together alongside Portsmouth International Port and Brittany Ferries to deliver the project. Sea Change has great potential, and project partners plan to share learnings and collaborate with ferry ports across the UK to encourage further emissions reduction. This will help the industry reach net-zero greenhouse gas emissions by or around 2050, a target declared by the International Maritime Organisation.
Alongside this, the project will help develop the necessary skills for green shipping and infrastructure, design, manufacturing and maintenance capability. Working alongside the Solent’s industry clusters, it will support education initiatives and help grow skills across the Solent, safeguard existing jobs through upskilling and create new high-skill opportunities, driving growth and investment across the region.
Sea Change is part of the Zero Emissions Vessels and Infrastructure competition (ZEVI), which was announced in February 2023, funded by UK Government and delivered in partnership with Innovate UK.
This year marks 50 years since Portsmouth City Council created the international port in 1976. Celebrations will begin with a launch event in Westminster presenting the latest economic impact report. On Saturday 13 June the port will host an open day so residents can see behind the scenes and find more out about all the activities at their port.
Councillor Steve Pitt, leader of Portsmouth City Council, said: “The port is widely regarded as the UK’s most successful local authority owned port, the anniversary offers the opportunity to celebrate the progress and the important role it plays as a city-owned port on a local, national and international level.
“The 50th anniversary year is a chance to put the spotlight and showcase roles at the port, highlighting the range of varied and interesting positions in the maritime industry as a future career for young people. Increasing local knowledge of what happens at the port, and an understanding of how it contributes to the city, is extremely valuable to the port to maintain our licence to operate from our most important stakeholders, our community.”
2026 also marks Portsmouth’s centenary, with many events and celebratory moments taking place to mark 100 years of city status. The port will be featuring in the city’s Wild Art Trail, which involves specially-commissioned sculptured lions positioned across the city, one of which is in the terminal building.
