Wave energy devices deployed

OE Staff Wednesday, 17 January 2018 09:57

Swedish wave energy developer CorPower Ocean has installed a C3 Wave Energy Converter (WEC) at Scotland's European Marine Energy Centre (EMEC). 

The half-scale C3 point absorber device was installed at EMEC’s Scapa Flow scale test site, offshore Orkney, in collaboration with local marine contractor Green Marine. The device was towed to site and the surface operated install sequence was successfully performed from the Green Isle multicat vessel. The C3 WEC was connected to a floating Microgrid unit provided by EMEC.  

The microgrid has been designed to allow the C3 device to behave as if it were grid connected by providing a stable voltage and frequency reference, simulating the impedance of a typical grid connection, absorbing power from the device under test and providing power to auxiliary systems. 

The offshore test follows dry testing in Stockholm, Sweden. The offshore deployment is looking to prove off-grid operations in an environment addressing market segments such as islands, offshore installations or remote coastal locations around the world.    


Meanwhile, Finnish wave energy developer Wello has now received its’ first order for a commercial wave energy park. 

Gapura Energi Utama (GEU), an Indonesian infrastructure construction company, has ordered a 10MW Wello Penguin wave energy park. The park will be next to Nusa Penida Island in Bali and it will be the largest wave energy park globally. The delivery will take place after a permitting process is finalized, expected by the end of 2018.

The Wello Penguin wave energy converter has been developed and tested for almost 10 years. The device has experienced the harshest ocean conditions and waves raising up to 18m, also at EMEC.

The Wello Penguin floats on water and captures kinetic energy from the waves, which is then turned into electrical power. The device does not have any moving parts in contact with sea water and the service needs are minimal. Remote connection allows for continuous monitoring and adjustment of the solution.

“The cost of energy generated with Wello Penguin is already very competitive compared to offshore wind energy, and in serial production we aim for a further 50% cost reduction,” says Heikki Paakkinen, the CEO and founder of Wello.

Wello says the potential market for the Wello Penguin in Indonesia is worth over a billion Euros. 

Komang Agus Pribadiana, President Manager, GEU comments: “Indonesia’s ocean wave energy potential is more than 17 GW, but not yet explored at all. Teaming up with Wello is truly a brilliant idea and a strategic maneuver to capture the huge ocean waves utility market. This alliance could ignite the fabrication of a 100% local content hull and other supporting equipment could be produced locally as well.”
