A global alliance focused on ocean energy was announced Monday, with members saying they want to promote the “sustainable implementation of ocean-based renewable energy” and, respectively, reduce the effects of climate change.
The members of the Ocean Renewable Energy Action Coalition, led by Denmark’s Orsted and Norway’s Equinor, also include organizations such as Shell, MHI Vestas, and Siemens Gamesa.
The coalition is set to focus heavily on the offshore wind but will also look at technologies such as wave power and tidal power
Many big and groundbreaking offshore wind energy projects have been growing in the last few years. These include 659 megawatt Walney Extension plant, which was officially launched in 2018, in the Irish Sea.
The size of this project is considerable: it can power over 590,000 homes, it has 87 turbines and it covers an area of about 20,000 soccer pitches. Orsted controls 50 percent of the initiative, with PFA and PKA holding 25 percent of Danish pension funds each.
For its part, Equinor says it has power over one million European homes that use offshore wind from UK projects.
While the coalition clearly focuses on renewable energy technologies like offshore wind, it should also be noted that members like Shell and Equinor are major producers of oil and gas. Equinor describes itself as “a leading explorer of new oil and gas fields” while in 2018, Shell says it produced 3.7 million barrels of oil equivalent per day.
In the field of ocean energy, a number of projects are taking place. A Scottish tidal energy company with a license to build a project at the Bay of Fundy, Nova Scotia, was released at the end of last year.
Nova Innovation said it would install a total of 15 tidal stream turbines by the year 2023. The project would generate enough electricity to power 600 homes as per the company.
Another company, Orbital Marine Power, is designing what it identifies as “the most efficient tidal turbine in the world.” The company says the turbine will have a sweeping area of over 600 square meters and will also be able to generate “more than 2 MW of tidal stream energy.”
It will use a “floating superstructure” of 72 meters to support two 1 MW turbines and is expected to be functional this year. It will be able to produce more than 1700 U.K. electricity. Homes, by company, by industry.
