of renewable electricity from the ocean every year, which explains why researchers are still trying to design energy conversion devices even after the field suffered a major disappointment in the early 2000s. Now all that hard work is beginning to pay off, and wave energy is poised for its breakthrough moment.If you’re guessing that a gigantic €9 million wave energy project under the wing of the firm Pelamis was the major disappointment, it sure was.
Beyond simply surviving at sea, wave energy converters also need to operate efficiently under a range of conditions defined as “normal” for the ocean. Converters need to be sturdy enough to handle storms, and they should also be able to operate efficiently even during periods of calm, when wave activity is minimal.
That’s just one example in a rapidly expanding field. An entirely different approach is illustrated by the Israeli startupInstead of floating its conversion devices out to sea, Eco Wave Power has come up with a port-side installation system that eliminates the cost of offshore anchoring systems and sub-sea electricity cables.off-grid at Joffa Port in Israel since 2014. Plans are in the works to expand that facility and connect it to the grid.
