Petroleum industry in Guyana is rapidly evolving. Guyana has emerged as one of the newest producing regions in the world, achieving its first commercial grade crude oil draw in December 2019. Crude oil is sent abroad for refining. Since the onset of production, Guyana has experienced a rapid increase in oil output, with production levels reaching approximately 660,000 barrels per day by 2024 . With plans to furthe. [pdf]

The CEOG hydrogen-based energy storage projectis being developed near Saint-Laurent-du-Maroni in north-western French Guiana. French Guiana is situated in northern South America, close to the equator. It, therefore, boasts 12 hours of daylight throughout the year, which will allow the CEOG solar-cum. . The CEOG power project is backed by a 25-year power purchase agreement (PPA) signed with the French utility EDF It will be connected to French Guiana’s electricity grid through EDF’s substation in Saint-Laurent-du-Maroni. The. . The CEOG power project will combine a 55MW PV solar farm and a 16MW high-pressure alkaline electrolyser to break water into hydrogen and oxygen using photovoltaic electricity. The facility will house a hydrogen storage. . The CEOG power project is being financed through long-term senior debt, equity bridge loan, tax credit bridge loan, and debt service credit. . The CEOG project is based on the Renewstable®power plant technology designed and developed by HDF to provide continuous or on-demand clean electricity from intermittent renewable energy sources. HDF is. [pdf]

Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of used by for . A PSH system stores energy in the form of of water, pumped from a lower elevation to a higher elevation. Low-cost surplus off-peak electric power is typically used t. Open-loop pumped storage hydropower systems connect a reservoir to a naturally flowing water feature via a tunnel, using a turbine/pump and generator/motor to move water and create electricity. [pdf]
Releasing water from the upper reservoir through turbines generates power. This process is crucial during peak electricity demand periods. Design Efficiency: The design of dams in pumped storage systems is tailored to maximise energy storage and generation efficiency. This involves considerations of dam height, water flow, and storage capacity.
The operations management of pumped storage power stations mainly includes power station operation, multi-energy complementarity, digital management system, profitability, and electricity consumption adjustment.
Reducing Operational Costs: By providing energy during peak demand, pumped storage can reduce the need for more expensive and less efficient peaking power plants, leading to cost savings in electricity generation.
CONCLUSION As the energy storage technology with the largest installed capacity and the most stable operation, pumped energy storage has effectively improved the stability of the power system. Three PSH technologies are mentioned in this paper. Among them, AS-PSH is more flexible and efficient than C-PSH in operation.
High Efficiency: The technology in pumped storage, including advanced turbines and generators, is designed for high efficiency. A large portion of the potential energy from stored water is effectively converted into usable electricity. Longevity and Cost-Effectiveness: These systems are efficient and durable.
Pumped storage is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.
