World’s First Wave Energy Array Goes Online

Business

Australia’s Carnegie Wave Energy has officially switched on a new onshore power station of its wave energy project—the world’s first commercial-scale, grid-connected wave energy array.

It is also represents the first time that wave-generated energy has been fed into the grid in Australia.

The Garden Island station uses the ocean’s waves to drive tethered underwater seabed pumps that feed high pressure water onshore to a hydroelectric power station.

The pumps are underwater to protect them from storms and corrosion.

In addition to driving the high-pressure water to the hydroelectric power station, the water also goes to a desalination plant, supplying both renewable energy and fresh water.

The power generated from the facility will be sold to the Australian Department of Defense, supplying Australia’s largest naval base, HMAS Stirling, with energy. The fresh water from the desalination plant will also be sold to the base.

The plant is the product of nearly 10 years of work and extensive testing from Carnegie Wave’s Perth Wave Energy Project and was switched on at a ceremony involving Australian Industry Minister Ian Macfarlance.

The Australian Renewable Energy Association (ARENA) is providing $13 million in funding support towards the $32 million project.

Ivor Frischknecht, CEO of ARENA, said:

This progress is a clear example that given time, and with the right government support, emerging renewable energy technologies can progress along the innovation chain towards commercialization.

Carnegie Wave is already taking the next steps to move its technology towards competitiveness with other power generation sources with the planning and design of Carnegie’s next generation CETO 6 technology.

Scotland produced enough power from wind turbines in the first half of 2019, that it could power Scotland twice over. Put another way, it's enough energy to power all of Scotland and most of Northern England, according to the BBC — an impressive step for the United Kingdom, which pledged to be carbon neutral in 30 years.

It's been a particularly terrible summer for bees. Recently, the U.S. Environmental Protection Agency (EPA) announced it is allowing the bee-killing pesticide sulfoxaflor back on the market. And just a few weeks prior, the USDA announced it is suspending data collection for its annual honeybee survey, which tracks honeybee populations across the U.S., providing critical information to farmers and scientists.
