One of the largest companies in the world has announced a £100 million investment in a green energy centre for the UK.
Mitsubishi is establishing an engineering centre in Scotland for research and development of offshore wind technology.
The firm expects to create up to 200 jobs at its Centre for Advanced Technology in Edinburgh. Mitsubishi is also acquiring an Edinburgh University spin-off, Artemis Power, safeguarding 25 jobs.
The move was welcomed by Scotland's First Minister, Alex Salmond, who said: "Scotland is a leader in the development of clean green energy and boasts a world-class research and development base that is pioneering technologies that will have a global impact on combating climate change."
The deal was made by Mitsubishi Heavy Industries (MHI) through its subsidiary, Mitsubishi Power Systems Europe (MPSE), and announced at a press conference in the Scottish capital.
The firm said the development builds on an agreement with the UK Government earlier this year to provide £30 million to support the overall investment.
The company aims to deliver the hydraulic technology in a large offshore wind turbine, which it expects will be a "game changer" in offshore power.
MPSE chief executive Akio Fukui said the selection of Scotland is a "significant milestone" and builds on Japanese links with the country.
He said: "The successful development of this technology will make Scotland a key player in the offshore wind supply chain, potentially leading to the development of manufacturing capacity delivering to the Scottish, UK and European markets.
"This exciting project squares the circle of the Scottish-Japanese industrial history dating back to when Thomas Glover assisted in the creation of MHI in the 1800s.
"The first Japanese naval vessel was built in Scotland in the late 19th century, and now the first game-changing wind turbine will be built here too."
