Japan is stepping up its role in global offshore wind, committing billions to projects abroad even as its domestic sector struggles to keep pace.
In mid-June, the U.K.-Japan Offshore Wind Industrial Compact was announced during Prime Minister Sanae Takaichi’s visit to the United Kingdom. The deal facilitates up to £9 billion ($11.4 billion) of investment from Japanese companies into the U.K.’s offshore wind energy sector and enables projects that will generate 5.9 gigawatts of power.
In everyday terms, if everything goes to plan, Japan-supported projects will generate enough energy to power 8 million U.K. homes. That is not an insubstantial contribution to a country that already has one of the highest fuel poverty rates in northern Europe and is facing further energy price increases as a result of conflict in the Middle East.
