For decades, engineers have been trying to find the very best way to capture the power potentialof the ocean. But, conditions ar sea are hash and developing technology to withstand waves is no simple task. But, like any important journey, success is increasingly likely with knowledge, time and persistence.
The WaveSub is immensely efficient in power generation, construction and installation – creating the potential for a substantially lower energy cost than has been achieved by other wave-based renewable energy technologies.
The WaveSub directly addresses the fundamental challenges facing devices generating energy at sea.
LOW COST OF ENERGY
Over the last nine years MPS has been focused on building a wave energy generation device that can address the four main challenges of energy generation at sea. With extensive sea trials and tank testing behind us and testing scheduled for the quarter scale prototype in Autumn 2017, we believe the WaveSub has potential to move forward the burgeoning marine energy industry by generating reliable, affordable wave power.
Once we have completed the build of our quarter scale WaveSub we will open a new round of fundraising to develop a full-scale multi-megawatt device required for the deployment of wave farms from 2020.
The WaveSub: addressing the challenges of energy generation at sea
The marine environment is extremely harsh, forces on any device must be limited
WaveSub alters its depth to optimise power and ducks under powerful storms
Subsurface orbital energy flow is powerful but often very difficult to harness
WaveSub operates under the surface of the sea, moving in orbital motion with the wave
Devices need to be cheap to build in relation to the power they produce
WaveSub doesn’t rely on complicated bespoke components and is optimised for commercially available manufacturing
Devices need to be quick and simple to deploy, recover and service
WaveSub floats to its install site and is designed to be easily moved and maintained
The WaveSub captures wave energy mid to far offshore by utilising the continual orbital motion of waves to drive a sophisticated PTO system. It’s ability to ‘hide’ from storms minimises stress put on the device.
Over 100 metres long and rated at 5MW in capacity, each WaveSub device can power approximately 5,000 homes. This is a similar power output to a large offshore wind turbine.
The WaveSub devices are cost effective to build, using pre-designed equipment with minimal bespoke engineering required. This means parts are simple to find and replace in the long term.
Deployed and maintained through the use of a simple tug, installation and service costs are kept low. The cost of WaveSub electricity is predicted to be competitive with off-shore wind.
