The Future of Energy
WAVE + POWER
Marine Power Systems Ltd (MPS) is a wave power technology development company. Based in Swansea, South Wales, it was founded in 2008 to develop and bring to market the WaveSub wave energy converter. MPS has dedicated the past nine years to making wave power work, to bring the most affordable, reliable and scalable wave technology to the world.
The WaveSub has the potential to substantially reduce the costs of energy generation from waves and favourably compete with the levelised cost of energy for offshore wind. Funded by a mix of public and private sector investment, MPS has completed two phases of the development of the technology and is currently undertaking Phase three: the design, build and testing of a quarter scale prototype. This will take place at the FaBTest site in Cornwall, UK in autumn 2017.

Why Wave Power?
Offering levels of consistency and density superior to that of wind and solar energy, the global wave energy resource can only be described as ‘vast’, with the potential, even if only partially exploited, to significantly reduce dependency on fossil fuels and carbon emissions.
WIND + SEA
When winds interact with the sea surface, friction between the air and the water first causes ripples, then chop, then waves.
The size of the waves depend on how strong the wind is, how long it has been blowing, and over what distance it has been blowing (the fetch).
Waves, unlike wind, do not disappear when the wind stops blowing. Instead, waves travel outwards from their source until they reach land where they become breaking waves.
The passage of swells through the open ocean is an incredibly efficient process – waves can travel hundreds, even thousands of miles with little loss of energy.
Global Energy Resource
The global wave energy resource can only be described as ‘vast’ with the potential, even if only partially exploited, to significantly reduce dependency on fossil fuels and carbon emissions.
Of particular interest, a practical resource of 50 tWh is available within the surrounding oceans of the UK. This is a significant proportion of the practical wave energy available globally and provides the United Kingdom with a unique opportunity to become a global leader in the development of wave energy technology.
The WaveSub has the potential to substantially reduce the costs associated with energy generation from waves. MPS has completed two Phases of the development of the technology and is currently undertaking Phase 3: Design, Build and Testing of a ¼ scale prototype.
1. Phase One
Phase 1 delivered a proof of principle prototype device that has undergone successful sea trials and energy generation tests at the world renowned National Renewable Energy Centre (NaREC) in Newcastle. The operating principles and ability to generate energy were proven by this prototype.
2. Phase Two
Phase 2 was a detailed desk engineering project to evaluate the cost of energy that the WaveSub is likely to deliver. This project comprised: an energy generation simulation exercise, design feasibility and costings of all parts of the WaveSub structure, installation and systems; and the costing of a maintenance plan for the WaveSub.
3. Phase Three
Phase 3 will see Marine Power Systems design, build and test a ¼ scale prototype at sea. This phase is underway, with the detailed design currently taking place. MPS have selected a number of industry expert project partners and subcontractors who are integral to delivering this phase.
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 renewable energy technologies.
The WaveSub directly addresses the fundamental challenges facing devices that try to exploit wave energy.
With a subsurface orbiting energy capture system, the WaveSub harnesses the entire energy cycle of the wave.
To combat the harsh environment, the WaveSub is depth adjustable allowing it to descend beneath storms when necessary.
TRANSPORTATION, OPERATION & MAINTENANCE
The floating surface configuration of the WaveSub makes it exceptionally easy to transport, install and maintain.
The WaveSub is cheap to manufacture due to its small size (for power produced), simple shape, and low structural loads.
The WaveSub has the potential to substantially reduce the costs associated with energy generation from waves. MPS has completed two Phases of the development of the technology and are currently carrying out Phase 3. Follow our latest updates for progress.

28 June 17 – PRESS RELEASE: New renewable energy report calls for global ambition of 10% wave energy by 2050
Making Wave Power Work provides an analysis of the economic and environmental potential that wave power offers both the UK and the rest of the world. It calls on industry and trade bodies to join up their communications around the 10% target and businesses and government to ramp up steady financial support and policy stability.
