The Danish company Resen Waves is currently developing a revolutionary green technology. In collaboration with Project Greensand, the company is developing buoys that can generate electricity through wave power to monitor Project Greensand's CO2 storage.
In addition to power production, the buoys can function as a wifi hotspot several hundred kilometers out in the North Sea. When the buoys are fully developed, they will be the first of their kind worldwide, Resen Waves said in a press release.
- It gives us a huge boost to be part of Project Greensand. We are one of the smallest companies in the consortium, but are considered equal. It just confirms the visionary ambitions of Project Greensand that we have also been invited. Capture and storage of CO2 is on the way all over the world. It gives us a huge springboard to be able to help demonstrate these new monitoring techniques, says Per Resen, CEO and founder of Resen Waves.
New way to monitor offshore
The buoys from Resen Waves will be of crucial importance to Project Greensand and will do away with the previous way of conducting offshore monitoring.
Traditionally, monitoring of offshore operations typically involves a manned ship sailing far out to sea to conduct its surveys. This is costly in terms of CO2 emissions, is a slow process and can, in the worst case, be a risk of occupational injuries. However, the buoy's network function eliminates the need for both the ship and crew to go to sea to collect monitoring data. This triggers a wide range of benefits.
First of all, the buoys ensure that green electricity is generated for the monitoring of the CO2 storage through wave power at sea. Secondly, the buoys' network function ensures that the collected monitoring data from the North Sea can be sent directly to land, where the data can then be examined immediately after collection. In addition, the buoys are automatic, which significantly reduces the risk of occupational injuries in connection with the monitoring.
- Project Greensand Phase 2 is about much more than just carrying out a pilot test of liquid CO2 into the Nini West Reservoir. We will develop the entire part of the CCS value chain that deals with the transport, storage of CO2 and monitoring of the CO2 in the reservoirs. Here, the buoys from Resen Waves are a brilliant example of how, with high ambitions, you can rethink the way the offshore industry traditionally operates," says Søren Reinhold Poulsen, Project Director at Project Greensand.
The buoys from Resen Waves are expected to be ready for final testing in the spring of 2023.
