The assessment of the Levelised Cost of Energy (LCOE) for ocean energy devices represents a critical element of understanding in the development of ocean energy array projects. While the cost of existing prototype devices is high, there is scope for significant reductions of the cost of energy.
The offshore environment can be used for unobtrusive, safe, and economical utility-scale energy storage by taking advantage of the hydrostatic pressure at ocean depths to store energy by pumping water out of concrete spheres and later allowing it to flow back in through a turbine to generate electricity.
The paper shows that deep ocean gravitational energy storage technologies are particularly interesting for storing energy for offshore wind power, on coasts and islands without mountains, and as an effective approach for compressing hydrogen.
Technology development and deployments are the main drivers for bringing the cost of energy of ocean energy technologies down; however external factors such as cost reduction of other RES technologies (e.g wind) provide further stimulus for ocean energy costs to be reduced quickly. Phase II:
While the cost of existing prototype devices is high, there is scope for significant reductions of the cost of energy. In order to unlock some of these cost savings, the deployment levels of ocean energy converters will need to ramp up and projects must progress into the construction and operation phases.
The study showed that whilst progress has been made, the rate at which cost-reduction and technology deployment have taken place have been below par with expectations in the sector. Further progress is needed in order to build confidence in the ocean energy sector, and in each specific technology market.
