LYNGBY, Denmark  Resen Waves is working with the Project Greensand carbon capture and storage consortium to assess use of small-scale wave energy buoys, with the power used to monitor offshore activities.

The consortium of 23 companies and organizations that collaborate plan to store captured CO2 in a Danish North Sea reservoir.

Last December, the EUDP awarded Project Greensand a DKK197-million grant toward developing and demonstrating CO2 storage in the North Sea. The project is currently in Phase 2, developing, testing and demonstrating the process.

Resen Waves is developing buoys that, through wave power, would generate electricity for monitoring the CO2 storage and detecting any leaks. The buoys would also serve as a Wi-Fi center, several hundred kilometers offshore.

Traditionally, crewed vessels monitor offshore operations. According to Resen Waves, the buoys’ data communications capability would remove the need for ships and crews.

Their duties would be to:

  • Ensure renewable energy is used for monitoring of the CO2 storage by harnessing wave power; and
  • Use their network function to ensure the compiled data can be sent directly to shore for examination.

The buoys are autonomous and would reduce the risks and workload of monitoring.

They should be ready for the final tests in spring 2023.
