The vision of this project is to develop and demonstrate a viable energy storage method for offshore purposes by means of the flywheel technology. It will lower the energy consumption of the drilling vessels by 20% at a substantially lower price compared to other energy storage solutions, thus developing a new Danish industry in energy storage.
A flywheel is an energy storage system where a specific mass (the flywheel) is rotated in a vacuum, which allows energy to be stored by acceleration and discharged by deceleration. Most significant advantage of Flywheel Energy Storage System (FESS) compared to other energy storage devices is the ability of fast power charge and discharge that makes this technology superior and the most suitable for offshore applications aboard a drilling vessel. Currently batteries have been deployed in a few maritime settings, but batteries are not the right solution for demanding maritime use for energy storage due to low lifetime with a discharging capacity of 2,000 times compared to FESS that can be charged 25K- 50K times.
For this project, the FESS will be developed and demonstrated to meet the specific requirements for drilling vessels and vessels. The project will integrate FESS technology into the power distribution systems of drilling vessels and vessels to increase their efficiency. By using FESS the vessels can use smaller engines and increasing operational load point leading them to operate with improved fuel efficiency, where the FESS will kick in when additional power is needed. Vessels are having fluctuating power demand during their operations meaning that their engines are chosen according to the maximum load needed.
