Richard Yemm is the British inventor of the Pelamis Wave Energy Converter and was director of the former Pelamis Wave Power, a company he founded in Edinburgh in 1998. [1] [2] In 2014 he co-founded a new company, Quoceant, who are engineering consultants specializing in marine energy and technology innovation.
Yemm studied mechanical engineering at the University of Edinburgh from 1985 to 1989, graduating with a first class honours degree. [3] As an undergraduate, he was also awarded a Half Blue for sailing in 1986–87 by the Edinburgh University Sports Union, denoting performance to a high standard. [4] He completed his PhD in 1994 [3] under Professor Stephen Salter, former Saltire Prize medallist [1] and inventor of the Edinburgh duck wave energy device.
He went on to pursue a career as a self-employed design and development engineer on renewable energy projects, [5] gaining experience in the wind energy industry. [6] He invented the Pelamis Wave Energy Converter for generating electricity from marine waves, and established Ocean Power Delivery Ltd in 1998 to develop the product. [5] The company is now called Pelamis Wave Power Ltd. Yemm was CEO until August 2007, raising substantial investment and gaining commercial orders from 2005 onwards. [6] He then became CTO of the company.
Yemm was Chairman of the Board of Scottish Renewables trade association for over five years, [6] and is active in promoting renewable and wave energy.
In March 2012 Yemm was presented with the Saltire Prize medal by Scottish First Minister Alex Salmond. The chief executive of Scottish Renewables, Niall Stuart, said, "Richard Yemm will undoubtedly be looked upon as one of the most influential people to the development of Scotland's marine industry; from the drawing board to grid connected devices and making important steps to commercial scale projects."

Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC).
The Pelamis Wave Energy Converter was a technology that used the motion of ocean surface waves to create electricity. The machine was made up of connected sections which flex and bend as waves pass; it is this motion which is used to generate electricity.
Wavebob was a wave energy converter which was in development between 1999 and 2013 when the company was closed owing to funding difficulties.
The Wave Hub is a floating offshore wind and wave power research project. The project is developed approximately 10 miles (16 km) off Hayle, on the north coast of Cornwall, United Kingdom. The hub was installed on the seabed in September 2010, and is a 'socket' sitting on the seabed for wave energy converters to be plugged into. It will have connections to it from arrays of up to four kinds of wave energy converter. A cable from the hub to main land will take electrical power from the devices to the electric grid. The total capacity of the hub will be 20 MWe. The estimated cost of the project is £28 million.
The Aguçadoura Wave Farm was a wave farm located 5 km (3 mi) offshore near Póvoa de Varzim north of Porto in Portugal. The farm was designed to use three Pelamis Wave Energy Converters to convert the motion of the ocean surface waves into electricity, totalling to 2.25 MW in total installed capacity. The farm was officially opened on 23 September 2008, by the Portuguese Minister of Economy. The wave farm was shut down two months after the official opening in November 2008.
The European Marine Energy Centre (EMEC) Ltd is a UKAS accredited test and research center focusing on wave and tidal power development based in the Orkney Islands, UK. The centre provides developers with the opportunity to test full-scale grid-connected prototype devices in unrivalled wave and tidal conditions.
Pelamis Wave Power designed and manufactured the Pelamis Wave Energy Converter – a technology that uses the motion of ocean surface waves to create electricity. The company was established in 1998 and had offices and fabrication facilities in Leith Docks, Edinburgh, Scotland. It went into administration in November 2014.
Stephen Hugh Salter, is Emeritus Professor of Engineering Design at the University of Edinburgh and inventor of the eponymous Salter duck wave energy device. Salter is also a proponent of geoengineering and is responsible for creating the concept of the mechanical enhancement of clouds to achieve cloud reflectivity enhancement.
Ocean Power Technologies (OPT) is a U.S. publicly owned renewable energy company, providing electric power and communications solutions, services and related for remote offshore applications. The company's PowerBuoy wave energy conversion technology is theoretically scalable to hundreds of megawatts and the generated energy from wave power can be supplied to the grid via submarine cables. Several projects were undertaken around the world, but the economic viability of the theoretical concept has been problematic.
The Oyster is a hydro-electric wave energy device that uses the motion of ocean waves to generate electricity. It is made up of a Power Connector Frame (PCF), which is bolted to the seabed, and a Power Capture Unit (PCU). The PCU is a hinged buoyant flap that moves back and forth with movement of the waves. The movement of the flap drives two hydraulic pistons that feed high-pressured water to an onshore hydro-electric turbine, which drives a generator to make electricity. Oyster was stationed at the European Marine Energy Centre (EMEC) at its Billia Croo site in Orkney, Scotland until the company ceased trading in 2015.
Marine energy or marine power refers to the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world's oceans creates a vast store of kinetic energy, or energy in motion. Some of this energy can be harnessed to generate electricity to power homes, transport and industries.
Aquamarine Power was a wave energy company, founded in 2005 to commercialise the Oyster wave energy converter, a device to capture energy from near-shore waves. The company's head offices were in Edinburgh, Scotland. The company ceased to trade on 20 November 2015.
The Aegir wave farm was a planned wave farm off the south west of Shetland. The project was developed by Aegir Wave Power, a 2009 formed joint venture of Vattenfall and the wave power technology developer Pelamis Wave Power. The wave farm would have had capacity from 10 MW potentially up to 100 MW. Following the collapse of Pelamis in November 2014, the project was cancelled by Vattenfall in February 2015.
The Saltire Prize, named after the flag of Scotland, was the national award for advances in the commercial development of marine energy.
Yemm is an English surname derived from an old word for uncle in its dialectal form from the Forest of Dean.
Peter Fraenkel, MBE, is a marine engineer, visiting professor at the University of Edinburgh School of Engineering and a fellow of the Institution of Mechanical Engineers and of the Energy Institute. He is the inventor of the tidal power plant SeaGen.
Wave Energy Scotland (WES) is a technology development body set up by the Scottish Government to facilitate the development of wave energy in Scotland. It was set up in 2015 and is a subsidiary of Highlands and Islands Enterprise (HIE) based in Inverness. WES manages several projects resulting from its pre-commercial procurement funding calls.
The Ocean Grazer is a conceptual energy collection platform, projected to house several renewable energy generation modules, including wave energy, solar energy and wind energy. The development of the Ocean Grazer platform has been carried out by the University of Groningen in the Netherlands.
