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 ).

How does a compressed air energy storage plant work?

A Compressed Air Energy Storage (CAES) plant works by pumping and storing air in an underground cavity or a container when excess or low-cost electricity is available. The stored energy is recovered by mixing the compressed air with natural gas. This compressed mixture is burned and expanded in a modified thermal turbine.
