Mobile Wave Energy Harvesting System is developed by Researchers from Fraunhofer Center for Manufacturing Innovation. By turning ships into mobile wave energy harvesters, you can cheaply and efficiently go out to the ocean and haul a big fat load of electricity back to your hungry customers. It’s like fishing, but it is for power. Mobile Wave Energy Harvesting System can be used with all small- and medium-sized boats used for fishing.

Mobile Wave Energy Harvesting System for Electric Power Generation on Sea Fishing BoatsThis idea of mobile wave energy harvesting is a simple one: you put wave energy harvesters on boats, send those boats out to sea, they sit out there for about a day riding the swell and charging their batteries, and then they come back in to shore and offload their electrical cargo. There’s no complex and expensive undersea construction, no need for cables to run back to shore (at $1 million per mile), you can move the generators around easily, and best of all, we can retrofit ships to do this relatively cheaply.

Each 150 foot ship (like the concept pictured above) would be able to harvest about one megawatt of energy per hour, which is enough to power about a thousand homes. It would store up 20 megawatts in giant batteries over 20 hours at sea under average conditions, and then head back to port and pump all of that power into the grid. Once the transfer is complete, the generator can go back out again and fish up another load. Get enough ships together, and you can harvest as much power as you need, since it’s not like you’re going to use up all the waves or anything.

Features of Portable Wave Energy Harvesting System

  • Harvests wave energy with daily trips to offshore locations and returns back to port for delivery to the grid
  • Energy is stored locally on the vessel during harvesting phase
  • Energy is placed on the grid during periods of high demand (normally mid-day)
  • Eliminates expensive undersea power cables needed for other wave energy technologies
  • Can be moved safely to port during severe storms
  • Overcomes regulatory hurdles by not being a permanent structure
