Energy storage, which helps to balance out the imbalances between energy production and demand, is the process of storing energy produced at one moment for consumption at a later period.
Generally speaking, a battery or accumulator is a device that stores energy. In addition to radiation and chemical energy, there are also kinetic energy, latent heat, gravitational potential energy, and potential for electricity and electricity at high temperatures. Converting energy from forms that are challenging to store to forms that are easier or more practical to store is referred to as energy storage.
Short-term energy storage is offered by some technologies, whilst long-term energy storage is offered by others. Hydroelectric dams—both traditional and pumped storage—constitute the majority of energy storage today. An assortment of techniques is employed in grid energy storage to store energy on a wide scale within an electrical power system.
The rechargeable battery, which stores chemical energy easily converted to electricity to power a mobile phone, the hydroelectric dam, which stores energy in a reservoir as gravitational potential energy, and ice storage tanks, which store ice is frozen by less expensive energy at night to meet peak demand for cooling during the daytime, are common examples of energy storage.
Coal and gasoline are examples of fossil fuels. These fuels were once living organisms that harvested energy from sunlight before dying, becoming buried, and eventually becoming these fuels. Food is a chemically stored kind of energy that is produced using the same mechanism as fossil fuels.
The South Africa Energy Storage Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The first energy storage plant under Eskom’s flagship Battery Energy Storage System (BESS) project has begun construction. At the Elandskop BESS site in KwaZulu-Msunduzi Natal and Impendle Local Municipalities, a sod-turning ceremony was performed. Eskom and Hyosung Heavy Industries, one of the BESS project’s chosen service suppliers, are working on the project.
The facility’s 8MW capacity, or 32MWh of distributed electricity, will be sufficient to power a community like Howick for four hours. According to the utility, one of the BESS’s significant advantages is that it will strengthen the network during peak hours, lessening the stress on the network at certain times.
South Africa’s state-owned power utility, Eskom, has partnered with Tesla, a global leader in electric vehicle and energy storage technology. The partnership focuses on deploying large-scale energy storage systems that can store excess energy during times of low demand and release it during peak periods.
By harnessing Tesla’s expertise in battery technology, Eskom aims to enhance grid stability, reduce the need for load shedding, and integrate renewable energy sources more effectively. This partnership underscores the potential for collaboration between established utilities and innovative tech companies to modernize energy infrastructure.
SANEDI, the national agency responsible for driving energy innovation and sustainability, has joined forces with Fluence, a leading energy storage solutions provider, to accelerate the adoption of energy storage in South Africa.
The partnership aims to develop and implement advanced energy storage projects that can facilitate the integration of renewable energy sources, enhance grid resilience, and support rural electrification efforts. Through joint research and project deployment, SANEDI and Fluence are contributing to the diversification of South Africa’s energy mix and the reduction of carbon emissions.
The Redstone Solar Thermal Power Project, located in the Northern Cape province, has partnered with ACWA Power, an international developer of power and water projects. This innovative project combines concentrated solar power (CSP) technology with thermal energy storage to provide a stable and dispatchable source of renewable energy.
The partnership with ACWA Power brings expertise in project development and financing, enabling the Redstone project to provide reliable energy to the grid, even after sunset. This collaboration exemplifies how energy storage can complement renewable energy generation to ensure a consistent power supply.
SARETEC, a leading training and research institution for renewable energy technologies, has partnered with Doosan, a global infrastructure solutions provider. This partnership aims to advance the field of energy storage through research, development, and education.
By combining SARETEC’s expertise in renewable energy training with Doosan’s engineering capabilities, the collaboration seeks to develop skilled professionals capable of designing, installing, and maintaining energy storage systems. This partnership not only supports the growth of the energy storage industry but also addresses the need for specialized training in this evolving sector.
