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.

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 ).

Why should I use PHES facilities in Oman?

Since PHES facilities have been used in several countries around the world and the technology is relatively mature, and also because the load centre in Oman is in the Muscat governorate, which forms an excellent location considering geological factors, this technology is recommended. There are two options for PHES facilities in MIS.

What are the different types of energy storage systems?

Mainly, they can be divided into two groups: electrical and thermal energy storage systems. Electrical energy storage systems are also classified into electrochemical, chemical, mechanical, and electromagnetic. Examples of electrochemical storage systems are fuel-cells and batteries.

What is a battery energy storage system (BESS)?

Of late, however, the use of Battery Energy Storage Systems (BESS), based on lithium-ion or other technologies, is becoming increasingly efficient and popular, particularly in conjunction with solar, wind and other such resources.

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.
