WORLD UNIQUE WAVE POWER BREAKTHROUGH
June 2nd, 2017, was a milestone for fossil free energy in general and for Waves4Power in particular
The Waves4Power wave energy system was connected to shore and started to deliver electricity to the Norwegian power grid. This took place at Runde on the Norwegian west coast; an optimal place for wave power with its abundance of strong waves.
The Waves4Power wave energy system consists of the WaveEL buoy, a connection hub and custom designed proprietary marine cables from the buoy to the hub and from the hub to shore. The cable from the hub to shore is 3km long. The complete system is the result of years of development work, prototypes and testing. This is

a full-scale demonstration installation and the first step towards commercial serial production. The serial production site will be at Fiskåholmen shipyard in Vanylven municipality. Stryvo Group AS, Stryn is responsible for the production.
IF WE CAN MAKE IT HERE WE’LL MAKE IT ANYWHERE The WaveEL buoy was deployed at Runde in February 2016. A week after deployment, the system was challenged with 14m high waves at the launch site. This is what we call a real live test of system survival even though the mooring system’s design parameters are for substantially larger waves than this. In April and May of 2017 the complete system was finally installed on site and connected to the land-based power grid. Runde Environment Centre and Tussa
Energy, the local power company, have played important roles in making this possible. The marine operations have been planned, supervised, and performed by BlueOrbis AB and Olympic Shipping AS.
IMPORTANT SUCCESS FACTORS Waves4Power has built a unique network of industrial partner companies. Each partner company is an industry leader in their respective field of business and they take full responsibility for their solutions in the complete wave energy system. This collaborative approach to the work adds immeasurable credibility to Waves4Power and speeds up the development process.
CAPTURING THE MOTION OF
NEAR-SHORE WAVES While the conversion of waves into energy has been the focus of hundreds of companies, engineers and scientists globally, significant barriers still exist in harnessing wave energy on a commercial scale
Most of the existing wave power technologies operate in the offshore - several miles into the ocean, where waves theoretically can generate large amounts of energy. The conditions in these locations, however, are often extreme, unpredictable and multi- directional, presenting a high risk to the equipment’s survivability during stormy conditions. These factors make offshore systems both unreliable and uninsurable.
HIGH COSTS Aside from being unreliable and uninsurable in these environments, the costs of these power stations are quite high, as construction and maintenance require sea-specialised workers, boats, divers and special and expensive equipment. Such prices are even more elevated when taking into account the need to transmit the energy back to shore. Obtaining necessary environmental approvals is also a difficulty, since offshore projects usually connect to the sea floor and create new presence in the marine environment, which is highly objected to by environmentalists.

SOPHISTICATED TECHNOLOGY Overcoming these barriers, Eco Wave Power (EWP) developed simple, but
sophisticated and robust technology. Floaters, attached to existing ocean structures such as breakwaters, piers, jetties, seawalls and more, rise and fall with the up and down motion of water and the incident flux of waves producing hydraulic pressure. The produced hydraulic pressure is then converted into electricity through land located smart conversion units. EWP’s near-shore wave energy generation system was recognised as a “Pioneering Technology” by the Chief Scientist at the Israeli Department of Energy and Infrastructure and came to light as a breakthrough technological solution which overcame the barriers halting the wave power industry.
SUCCESSFUL TESTING PHASE Testing their system in the wave pool of the Hydro Mechanic Institute in Kiev, EWP proved that large amounts of energy could be generated through near-shore technology. After completing a successful testing phase, EWP created a trial station on the Crimean Peninsula to confirm the system’s ability to withstand real maritime conditions. This system was later transferred to Jaffa Port in Tel-Aviv, Israel, where, for the past three years, it has been operating continuously as an R&D station. In its
Israel R&D station, the automation, storm-protection mechanisms and unique floater shapes were developed, while additional optimisation testing continues to this day.
Following the development of its R&D station, EWP signed a 5 MW PPA with the government of Gibraltar. The initial wave power station of the project was completed in May 2016 and was the first commercial-grid connected wave energy station in Europe. The power station is insured by a reputable UK insurance company and the day-to-day production of energy imposes zero impact on the harboring environment. The system is operated by land-based technicians and the transmission of electricity to the grid is cost-efficient and highly competitive, after over a year of operation, the Gibraltar plant has proven itself to be both economical and reliable.
