Which utility-scale energy storage options are available in Oman?

Reviewing the status of three utility-scale energy storage options: pumped hydroelectric energy storage (PHES), compressed air energy storage, and hydrogen storage. Conducting a techno-economic case study on utilising PHES facilities to supply peak demand in Oman.

Can PHES facilities supply peak demand in Oman?

Conducting a techno-economic case study on utilising PHES facilities to supply peak demand in Oman. This manuscript proceeds by reviewing the status of utility-scale energy storage options in Section 2. Section 3 presents the status and main challenges of Oman’s MIS.

How can energy storage improve the penetration of intermittent resources?

Energy storage can increase the penetration of intermittent resources by improving power system flexibility, reducing energy curtailment and minimising system costs. By the end of 2018 the global capacity for pump hydropower storage reached 160 GW whereas the global capacity for battery storage totalled around 3 GW (REN21 2019 ).

Which country has the largest pumped hydroelectric storage capacity?

The world’s largest installed capacity is in Japan, with a total capacity of 25 GW. The second largest installed pumped hydroelectric storage capacity is in China, followed by the USA (Energy Storage Association 2018 ). There are 40 PHES systems in the United States, with a total storage capacity exceeding 22GW (Ceci et al. 2018 ).

How do energy storage systems work?

Energy storage systems currently in use around the world save energy in a variety of forms – chemical, kinetic, thermal and so on – and convert them back to electricity or other useful forms. In Pumped Hydroelectric Storage, for example, the system consists of two reservoirs maintained at different heights.

What is energy storage?

Energy storage encompasses the ability to capture energy at a time of, say, surplus availability, for use later at a time when access to an energy source is either unavailable, limited in supply or intermittent.
