[PDF Version]Among the three main types of hydropower schemes (run-of-river, storage, and pumped storage), the first two are common in Afghanistan. Access to and proper use of water resources are fundamental factors in the socio-economic development of a nation.
Numerous electricity-generating facilities were built and utilized throughout the country. The largest share of this capacity depends on water resources . The Naghlu hydroelectric power plant is one of the largest hydroelectric dams in Afghanistan. Construction of this dam began in January 1960, and was completed in 1968.
Furthermore, ensuring efficiency is the most important point for hydroelectric power plants in Afghanistan, which are running at efficiencies several times lower than their installed capacity.
Of these types, run-of-river type and storage type hydropower dams are used in Afghanistan, although the latter is rare. Reports indicate that more than 160 micro-hydropower plants are installed in Afghanistan, with a total usable capacity of 75.14 MW, . Among these micro-hydropower plants, 30–40% are not operational .
Afghanistan has about 123 years of experience in hydropower generation with enough potential to generate tremendous electricity from hydropower projects, not only for self-sufficiency but also to export electricity to Pakistan and India as well.
The availability of water resources in Afghanistan makes feasibility studies of hydropower dams essential; therefore, these resources have received region-wide attention. In 2015, Chinese experts surveyed the Kunar River and reported an estimated installed capacity of 1500 MW, .
Herein, the technological development status and economy of the whole industrial chain for green hydrogen energy “production-storage-transportation-use” are discussed and reviewed.
The environmental benefits of hydrogen storage technologies heavily depend on the method of hydrogen production. Green hydrogen, produced using renewable energy sources like wind or solar power through electrolysis, is considered environmentally friendly as it avoids carbon emissions associated with traditional production methods.
Some of the common challenges to opportunities of hydrogen storage are highlighted below. 1. Low Energy Density by Volume: Hydrogen has a low energy density per unit volume, leading to the need for efficient storage technologies to store an economically viable amount of energy.
Opportunities Hydrogen storage offers several opportunities that make it an attractive option for energy storage and distribution. Some of the opportunities for hydrogen storage are. 1. Decarbonization: Hydrogen storage can improve energy security by enabling the storage and distribution of energy from diverse sources.
The findings demonstrate that incorporating an energy storage system (ESS) can cut operational costs by 18 %. However, the utilization of a hydrogen storage system can further slash costs, achieving reductions of up to 26 % for energy suppliers and up to 40 % for both energy and reserve suppliers.
Conducting a comprehensive life cycle analysis of hydrogen storage technologies is crucial to assess their environmental impact from production to end-of-life. This includes evaluating resource use, emissions, and energy consumption at every stage. Assessing the sustainability of materials used in hydrogen storage technologies is important.
Finally, in terms of hydrogen energy applications, with the gradual upgrading and progress of top-level design and technology, hydrogen energy applications based on transportation, industrial engineering, energy storage, electricity to gas and microgrids will show a diversified development trend. 5.2.

Hydrogen offers a potential energy storage medium because of its versatility. The gas can be produced by electrolysis of water, making it easy to integrate with electricity generation. Once made, the hydrogen can be burned in thermal power plants to generate electricity again or it can be used as the energy source for fuel cells.
Compare hydrogen and competing technologies for utility- scale energy storage systems. Hydrogen is competitive with batteries and could be competitive with CAES and pumped hydro in locations that are not favorable for these technologies.
The hydrogen energy storage system is divided into four parts, namely, the power supply module, the electrolytic cell, the compression part, and the high-pressure gas storage, as shown in Fig. 10. From Fig. 5, it can be seen that the power supply module includes a DC/DC buck converter, LC inductor, and capacitor element.
The electrolytic cell is the core of the hydrogen storage system, in which electrical energy is converted into heat and chemical water to obtain O 2 and hydrogen. The compressor is used to compress H 2 and store it in the high-pressure gas storage tank [18,19,29]. Fig. 10. Hydrogen storage system.
Solar and wind power intermittency and demand non-coincidence require storage. Hydrogen energy storage is one of the only options with sufficient storage capacity. Hydrogen can provide seasonal storage, zero emissions fuel and chemical feedstock. Gas grid can evolve, store and distribute increasing hydrogen amounts at low cost.
The primary limitations of hydrogen energy storage systems are the durability of the system components, high investment costs, and possible geographic requirements related to the hydrogen storage vessel [28,30].

The Chinese-built 344-MW Kokhav Hayarden pumped storage hydropower plant is expected to be operational in early 2023, which will help reinforce the grid stability in Israel.
China Media Group The China-built 344-MW Kokhav Hayarden pumped storage hydropower plant, located near the city of Beit She'an and some 120 kilometers away from Tel Aviv, is expected to be the largest pumped storage power plant in Israel when it becomes operational in early 2023.
In Israel, many coal and gas power stations operate alongside plants that use renewable energy from natural sources. A large amount of electricity is not used, and in fact is discarded, due to a lack of effective storage options. Pumped storage uses this surplus electricity to raise water from the lower reservoir to the upper reservoir.
The Manara Pump Storage Project will have an installed capacity of 156 MW (single 156 MW unit). The design of the system is compliant with a daily cycle (generation and pumping). The project includes one pump-turbine unit that is able to convert the hydraulic energy into electric energy and vice-versa.
The Gilboa power station serves as an important tool for managing and controlling the electrical grid, when needed. The foremost advantage of a pumped storage power plant is its response time. Within just 90 seconds, 300 MW can be added to the electrical grid, thus overcoming peak demand.
The Gilboa pumped storage project was established by a special partnership between Electra Construction, Electra Energy (formerly Elco), and Solel Boneh, and will be operated by Alstom Ltd. The project is being built within approximately 5 years, at a cost of some NIS 2 billion.
The Kokhav Hayarden pumped storage plant is equipped with two General Electric (GE) 172MW Francis turbines and pump units in an underground powerhouse cavern.

[PDF Version]One of the most promising types of such systems is the solar hydrogen energy system (SoHyS) where essentially the electricity produced by the PVs is stored in the form of hydrogen by using a variety of storage methods and means. The hydrogen can be then reconverted to electricity on demand by using a fuel cell.
This problem can be overcome by storing energy in the form of hydrogen either for long or short term. One of the most promising types of such systems is the solar hydrogen energy system (SoHyS) where essentially the electricity produced by the PVs is stored in the form of hydrogen by using a variety of storage methods and means.
The positioning of hydrogen energy storage in the power system is different from electrochemical energy storage, mainly in the role of long-cycle, cross-seasonal, large-scale, in the power system “source-grid-load” has a rich application scenario, as shown in Fig. 11. Fig. 11. Hydrogen energy in renewable energy systems. 4.1.
Application of hydrogen energy on the load side It can be used as a power source for the transport industry, as a fuel for combined heat and power systems or as an industrial raw material for the production of industrial products. Fig. 13 shows the application of hydrogen energy on the load side.
To actively develop clean hydrogen production methods in the power system, reduce the use of “grey hydrogen” and “blue hydrogen,” and increase the use and development of “green hydrogen”, which is made from renewable energy.
Unlike other forms of energy storage, hydrogen can be transported and used at a different location. There are a few advantages of the hydrogen energy storage in solar plants: Hydrogen generation by electrolysis is a well-established technology. Hydrogen is used in multiple branches of industry, so the procedures for its handling are well developed.
