Liverpool planning major tidal power project for River Mersey

Authorities in Liverpool are planning a major construction project on the River Mersey to harness tidal power which is hoped will power as many as 1 million homes.

If built, the facility would have a capacity of at least 1 gigawatt and make use of the Mersey’s significant tidal range.

Over the last two years, the mayoral authority has undertaken early technical work to develop the potential scope of the scheme it hopes will be up and running within a decade. 

The scheme aims to play a huge role in the region’s ambitions of net zero carbon by 2040.

In December, Liverpool City Region Mayor Steve Rotheram signed an agreement with South Korea’s state water company.

Korea Water Resources Corporation, known as K-water, vice president Jeong kyeongyun signed an historic Memorandum of Agreement with Mayor Rotheram. 

K-water owns and operates the world’s largest tidal barrage in the Gyeonggi Province.

The agreement paves the way for close co-operation between the two tidal power projects through reciprocal visits, co-operation and information sharing.

The agreement with K-water is part of a wider strengthening of links between the Liverpool City Region and South Korea.

As part of the UK-Republic of Korea Innovation Twins Programme, the city region is developing links with Busan, South Korea’s second largest city.  The programme is aimed at developing long-term research and innovation links, creating a pipeline of opportunities for bilateral trade and foreign direct investment.

The move is the latest stage of engagement between the Liverpool City Region Combined Authority and K-water which began with meetings at Glasgow’s COP26.

K-water built and operate the Sihwa Lake tidal range power plant. It has been operational since 2011 and generates 552GWh of green energy every year, replacing the equivalent of 862,000 barrels of oil a year.
