Ocean Harvesting Technologies AB (OHT) was founded in 2007 to develop a patented mechanical power take-off (PTO) for wave energy conversion comprising a planetary gearbox connected to a gravity accumulator. The technology efficiently converts the highly fluctuating power captured from ocean waves into a smooth speed and torque suitable to a conventional generator. The technology offers increased power output, compliance with grid quality requirements and reduces the need to oversize components.
OHT is a customer driven service and technology provider to wave power device developers, OEMs and other companies in the marine renewables industry. Product development is implemented in an open innovation strategy in co-operation with carefully selected technology suppliers and development partners, research institutes and strategic customers.
