Wavepiston has started a collaboration with Ørsted to investigate the potential for co-location of offshore wind and wave energy in Denmark. The collaboration will analyse the benefits of combining offshore wind and wave energy and show the potential of optimising the energy yield from the natural resources available in Danish waters.
A co-location of offshore wind and wave energy presents a multitude of benefits, including:
- Increased energy production: Utilising both wind and wave resources can lead to higher overall energy output from the same area.
- Enhanced grid stability: The combination of wind and wave energy can provide a more stable and reliable supply of electricity, reducing intermittency issues.
- Cost efficiency: Sharing infrastructure such as transmission lines, offshore operations, and surveillance can significantly reduce operational costs.
- Environmental benefits: Co-locating renewable energy technologies can minimise the environmental footprint compared to separate installations.
Emiel Schut, Wavepiston CCO, says: ‘We are excited about the opportunities this collaboration presents and the positive impact it can have on the environment and energy market of the future.’

Wavepiston technology
Multiple energy collectors are coupled on a string with each string corresponding to a wave energy converter. Each energy collector has a sail, which is moved back and forth by the passing waves. This movement drives hydraulic pumps generating pressurised seawater, which is piped to the conversion station (onshore or offshore) where the pressurised seawater is used to generate electricity via a standard hydropower turbine and/or desalinated water through a standard reverse osmosis system.
A wave energy farm will consist of multiple strings all pumping pressurised seawater to the common conversion station, scalable both to wave resources and to energy and/or water demands at the given location.
