The University of Edinburgh’s FloWave Ocean Energy Research Facility houses a 25m diameter circular pool containing more than 2 million litres of water and is designed specifically for testing marine renewable energy technologies.
The first of its kind in the world, this unique facility is able to accurately replicate real-sea conditions of waves and currents at scale for normal, challenging and extreme events for any offshore location. Enabling industry and academia to refine concepts, improve performance, and de-risk designs in a fully controllable and safe way at relatively low cost, FloWave will be a vital tool to help engineers harness the power of the sea.
FloWave can provide:
• 25m circular test tank of 2m useable water depth, with a raisable floor for easy access
• 360° monochromatic, multi-directional, multi-modal sea-states of up to 700m wave height
• 360° controllable current flows of up to 1.6 m/s, with ‘less than ocean’ levels of turbulence
• Simultaneous wave and current operation, for accurate ‘real-sea’ force combinations
• A test area >220m2 for array project testing and numerical model validation
• Unrivalled control and repeatability for ‘go away and come back’ evolutionary design
• Scale capabilities between 1/40th and 1/10th, optimised for 1/20th to meet sector needs
• Full instrumentation suite, including above and below water 3D motion capture
• Five tonne crane for model lifts, workshop facilities and client hot-desk space
• Technical engineering support from FloWave staff before, during, between and after testing
• Optional access to additional technical and academic expertise from the University’s School of Engineering and the Institute for Energy Systems
A complementary wave-only test tank on campus at King’s Buildings (the ‘Curved Tank’) is in the process of being upgraded to a parallel standard and means the possibilities for companies to test their products at the University are multiplied. When reinforced by a team of academics at the forefront of ocean energy research, companies can be sure that they have access to a unique proposition, a wealth of knowledge and the latest cutting-edge facilities.

ORQA is the very latest remote technology data monitoring platform designed specifically to capture a full meteorological, environmental, wave, tidal and foundation picture of offshore conditions and inform design, planning and environmental consenting phases for the offshore wind industry.
This innovative platform allows 24/7 offshore multi-data monitoring for the very first time. The ability to accurately measure offshore conditions offers real value to developers of offshore wind farm sites, significantly de-risking the project in the process thus allowing maximum return on investment made by offshore wind developers.
Using the ORQA platform, the following parameters will be measured:
– Wind speed and direction
– Barometric pressure, temperature and humidity
– Precipitation and visibility
– Water depth
– Wave height and direction
– Bird movements
– Presence of sea mammals
– Water temperature and salinity
– Inclination and deflection
– Internal strains Scour
The construction of offshore wind farms introduces significant risks to offshore wind farm developers, particularly for UK Round 3 sites further from the coastline. Costs will be greater for installations in greater water depths but could escalate if conservative parameters are adopted in design. It has been recognised that real data must be captured by deploying offshore monitoring devices thus ensuring that risks are properly quantified and analysed for all stages of the project life cycle through planning, design, construction and operation.
To aid the move towards capture of real data for offshore developments, Wood Group’s ORQA utilises the very latest in lidar technology, Galion, with its unique steerable beam, to capture critical wind speed and direction data over an extended range of 2km in any direction. Galion is not constrained to measuring directly above the device in the way other lidar devices are. Additional instrumentation monitors waves, currents and weather to verify existing metocean data while the monitoring of bird movements and sea mammals using radar and acoustic devices will inform the environmental assessment. The platform also contains provision to measure scour and to assess the real response of the foundation providing valuable feedback to the design.
The ORQA platform is a versatile solution which provides developers with a single turn-key option for advanced offshore wind data collection and consequently risk quantification for offshore development. Clients benefit from the fully customisable nature of ORQA allowing them to choose from the various advanced data capture options including meteorological, hydrological, environmental and foundation conditions to inform offshore developments with a greater degree of accuracy than ever seen before – benefiting the offshore wind industry by quantifying and mitigating the risks pertaining to individual sites.

Thin film solar cells are an emerging technology that can enable low-cost and highly efficient solar cells. However, thin film solar cells require light trapping to compensate for the otherwise poor absorption in the active thin film. Our supercell design concept for light trapping can provide optimized performance that is compatible with low-cost and mass production techniques.
Light absorption in thin films can be strongly enhanced when guided modes supported by the thin film are excited. This occurs when the diffraction angle of the light coupled by the grating matches the characteristic angle of the guided modes. Our invention – a novel design concept for diffraction gratings – explores large period gratings because these can excite more modes than typical light-wavelength scale gratings. To benefit from the larger period, we employ a supercell, i.e., a unit-cell consisting of fine features used to control the diffraction efficiency of the grating. The supercell is designed to shift the energy from the low diffraction orders, which cannot excite guided modes, to the higher diffraction orders, which are capable of exciting these modes.
Simple design concept that can be implemented in any kind of solar cell
Compatible with low-cost mass production technologies such as nano-imprint lithography
Light trapping is substantially improved at no additional fabrication cost
Absorption enhancement is stable against variation of light’s angle of incidence
Concept can be implemented in all types of gratings and combined with techniques such as randomized structures
Renewable electricity from sources such as wind, tide or solar are intermittent and cannot be controlled to times of peak energy use. The most convenient method of small-scale storage is the transformation of electricity into hydrogen for later transformation back into electricity by a fuel cell.
However existing electrolysers are inefficient resulting in a significant energy loss in the conversion and storage process adding to overall costs. The new technology surmounts these problems as the hydrogen production proces is substantially simplified and uses apparatus of relatively economic construction. New materials and designs have been developed to electrolyse steam at 500-600 degrees Celsius. The elevated temperature makes the conversion process more efficient by simplifying the production need, reducing the complexity of the balance of the plant and lowering the cost of the produced hydrogen. The new designs are based on protonic conducting membranes which should produce pure ready to use H2.
High temperature electrolysis is more efficient than at low temperature
Proton conducting membranes produce pure, dry hydrogen ready for use
Gives more effective generation when coupled with intermittent renewable energy generation
This new electrolyser could be used anywhere clean, dry hydrogen needs to be produced either at the site of generation or at distributed sites near the end users.There is an anticipated growing market of $20 billion/year in the US alone for hydrogen generation for fuel cell technology.
