Wave Energy


We believe the time to act on wave energy is now

Wave Energy Business Model

Our goal is to develop wave energy projects that will make a valuable contribution to global electricity demand.  Wave energy:

While wave energy is not yet as mature as wind energy, it is quickly gaining ground and the cost of wave energy is lower than the historical cost of wind energy at comparable levels of maturity. Levelised Costs of Energy (LCoE) for wave energy in 2030 is estimated to be between EUR 113-226/MWh if deployment levels of more than 2 gigawatt (GW) are achieved (IRENA, 2014).

Our Projects

Simply Blue has been interested in wave energy since its establishment in 2011. We completed a comprehensive, global, sector-wide Commercial Horizon Scan in 2016 which was updated again recently and we continue to monitor technology developments.

Simply Blue Energy’s first wave energy project, Saoirse, announced in 2020 will harness the tremendous wave potential of the Atlantic to help create a clean, sustainable future for everyone. Situated off the west coast of Clare, Saoirse will consist of a wave energy conversion array, approximately 4km from the coast.

The Project will utilise cutting-edge technologies to deliver a wave energy conversion array to produce zero-carbon electricity. The development will be a 5MW demonstration scale project with a future potential expansion up to 30MW which will consist of an interconnected array of devices, each generating energy with the rise and fall of the surface of the sea and feeding it back to land via an export cable.

This first-of-a-kind project aims to help Ireland progress towards a green energy future with domestically sources sustainable electricity delivering both environmental and economic benefits to the entire country and potentially beyond.

Wave Energy Potential

Global wave energy generation capacity is potentially as large as presently installed hydro power and likely larger than presently installed nuclear power.

Ireland and the UK (Cornwall & Scotland) have some of the highest generation capacity of wave resources in the world. Wave energy is measured in average power per unit crest length, e.g. kW/m or kW/km and annual averages are as high as 80kW/m in some locations. Ireland has an estimated 850km long 50kW/m wave power contour (Irish Wave Energy Atlas, ESBI & SEAI).

That is an installed power capacity input average of 42.5GW and an installed energy capacity input of 372.5TWh per annum.

The technically achievable electricity production from wave energy in Ireland is approximately equal to present consumption which stands at around 26TWh per annum.

It is estimated that the wave energy resource around the coast of the United Kingdom could meet 15% to 25% of current UK electricity demand. Related energy sales would be circa £2.5bn p.a. (excluding subsidies) and related technology and engineering sales would be circa £20-£30bn.

Since 2010, 11.3 MW of wave energy has already been installed in Europe, driven by testing opportunities and RD&I funding (Ocean Energy Europe, 2018).
