French Guiana underground energy storage

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 equat. . 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. . 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 elect. . 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. . The CEOG power project is being financed through long-term senior debt, equity bridge loan, tax credit bridge loan, and debt service credit facility from a group of development ban.

FAQS

How will a hydrogen power plant work in French Guiana?

This hydrogen will then be recombined with oxygen from the air in fuel cells to produce 24/7 non-polluting electricity and secure the supply of a competitively priced electricity, compared to the territory’s thermal power plants of the territory, to 10,000 households in French Guiana.

What is HDF Energy's $200 million Centrale Electrique de l'Ouest Guyanais?

HDF Energy’s $200 million Centrale Electrique de l’Ouest Guyanais (CEOG) project is based on its proprietary power-to-power Renewstable power plant. The plant will comprise a solar PV park, a 16-MW electrolysis platform, a long-term hydrogen storage unit, two 1.5-MW fuel cell systems, as well as a short-term lithium-ion battery storage unit.

How does ceog fit with French Guiana's energy strategy?

The population of French Guiana is very quickly increasing. Guiana has to face a considerable energy deficit, especially in the west where the demographic growth is booming. By providing several MW of reliable and clean energy, CEOG fits with French Guiana’s energy strategy.

How much daylight does French Guiana have?

FAQS

What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

Where is compressed air stored?

Compressed air is stored in underground caverns or up ground vessels , . The CAES technology has existed for more than four decades. However, only Germany (Huntorf CAES plant) and the United States (McIntosh CAES plant) operate full-scale CAES systems, which are conventional CAES systems that use fuel in operation , .

When did compressed air storage start?

The concept of large-scale compressed air storage was developed in the middle of the last century. The first patent for compressed air storage in artificially constructed cavities deep underground, as a means of storing electrical energy, was issued in the United States in 1948.

How does compressed air work?

Compressed air technology pressurises atmospheric air, converting it into stored potential energy (like compressing a spring). When electricity is needed, the compressed air is released to flow through an expander (turbine-generator) to produce energy.

Can compressed air energy storage improve the profitability of existing power plants?

Linden Svd, Patel M. New compressed air energy storage concept improves the profitability of existing simple cycle, combined cycle, wind energy, and landfill gas power plants. In: Proceedings of ASME Turbo Expo 2004: Power for Land, Sea, and Air; 2004 Jun 14–17; Vienna, Austria. ASME; 2004. p. 103–10. F. He, Y. Xu, X. Zhang, C. Liu, H. Chen

How does a geological storage facility use electrical energy?

This process uses electrical energy to compress air and store it under high pressure in underground geological storage facilities. This compressed air can be released on demand to produce electrical energy via a turbine and generator.

Underground cold energy storage technology

Underground thermal energy storage (UTES) is a form of energy storage that provides large-scale seasonal storage of cold and heat in natural underground sites. [3-6] There exist thermal energy supplying systems that use geothermal energy for cooling and heating, such as the deep lake water cooling (DLWC) systems which extract naturally cooled water under deep lakes as a source of cooling energy.

FAQS

What is underground thermal energy storage?

Underground Thermal Energy Storage (UTES) A thermal energy storage is a system that can store thermal energy by cooling, heating, melting, solidifying or vaporizing a material , such as hot-water, molten-salt or a phase-change material. Sensible heat storage (SHS) relies on the temperature variation of a solid or liquid (e.g. water).

Why is the underground a good place to store thermal energy?

The underground is suitable for thermal energy storage because it has high thermal inertia, i.e. if undisturbed below 10-15 m depth, the ground temperature is weakly affected by local above ground climate variations and maintains a stable temperature [76, 77, 78].

What is Utes (underground thermal energy storage)?

There are also combinations in which the storage is used for both short-term and seasonal storage. There are a number of such technologies summarized by the acronym UTES (Underground Thermal Energy Storage). 30 years within the framework of IEA (International Energy Agency).

What are the different types of underground energy storage technologies?

For these different types of underground energy storage technologies there are several suitable geological reservoirs, namely: depleted hydrocarbon reservoirs, porous aquifers, salt formations, engineered rock caverns in host rocks and abandoned mines.

Are solar energy storage systems underground?

The experience of USTES applications worldwide in recent years shows that most of the solar energy seasonal storage projects have significant economic, social and environmental benefits. However, the key part of solar energy storage system is underground.

Do Underground Technologies still have room for future improvements?

The described underground technologies still have plenty of room for future improvements, especially in what relates to efficiency and new developments of technologies, their costs and economics aspects. Criteria for selecting underground reservoirs are very important for the success of an energy storage facility.
