Mechanical energy storage methods are defined as those systems whose primary form of stored energy is kinetic or potential energy. Per Table 1, mechanical energy storage systems currently account for about 70% of all stored energy power capacity in the United States, with most coming from PHS.
Despite the growth of battery energy storage systems, mechanical energy storage systems remain a key component of energy storage for integrating renewables into energy production and providing most long-term storage options. Table 1. Share of US energy storage by type (EIA, 2023)
Large scale energy storage systems require significant investment and promise of return. With a TRL of 4, per Table 3, the next stage in the development of BEST is prototype testing on a larger scale in a relevant offshore location. Further development in BEST systems is necessary to achieve widespread use in offshore locations.
These systems include mainly pumped hydro storage (PHS), underground pumped hydropower, compressed air energy storage (CAES), and flywheel energy storage. These systems are used differently in a complete energy system based on their scalability and duration of storage.
Of the novel mechanical energy storage methods covered in this thesis, LAES and GES show potential in adding storage capacity to the energy grids. TRL, cost of stored energy, and term of storage indicate these two methods can penetrate the market and be competitive with or complementary to predominant storage solutions in the near future.
