Oman Energy Storage Container Size Design

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.

Electricity market structure in Oman Unlike the electrical energy sources used in traditional power plants, renewable energy sources are not dispatchable and will vary over time; as a result, the energy feed in the network will be intermittent.

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.

In 2015, Oman committed to an unconditional 2% emissions cut by 2030 at the United Nations Climate Change Conference. This target is to be achieved through reduction in gas flaring and increase in the utilisation of renewable energy (Carbon Brief 2016 ). The third challenge of the power sector in Oman is supply mix.

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 ).

Recently, the government in Oman introduced new policy that encourages the residential sector to instal photovoltaic (PV) cells on their rooftops. This is expected to have more energy produced from PV in the future, which will be fed back to the grid.
