Yemen has recently experienced a severe power shortage, unable to meet the power needs of its population and infrastructure. In 2009, the installed power capacity was about 1.6 GW, while, in fact, the power supply gap was about 0.25 GW. The power development plan (PDP) forecasts and estimates the capacity demand. . As mentioned earlier, according to the International Energy Agency, in 2000, oil made up 98.4% of the total primary energy supply in Yemen, while in 2017, oil made up about 76% of the total primary energy supply, and natural gas. . Yemen had a strategy to develop and improve its electrical potential before the events of 2011. The Public Electricity Corporation is responsible for developing this strategy, which is overseen by a group of power engineers. It. . According to the latest report of the World Energy Statistics Review 2020, 84% of the world’s energy is still supplied by fossil fuels, while renewable energy accounts for only 11% of global primary energy consumption.

However, Yemen’s current energy mix is dominated by fossil fuels (about 99.91%), with renewable energy accounting for only about 0.009%. The national renewable energy and energy efficiency strategy, on the other hand, sets goals, including a 15% increase in renewable energy contribution to the power sector by 2025 (Fig. 11).

Yemen is dealing with the dilemma of energy networks that are unstable and indefensible. Due to the fighting, certain energy systems have been completely damaged, while others have been partially devastated, resulting in a drop in generation capacity and even fuel delivery challenges from power generation plants.
Yemen has one of the highest levels of solar radiation in the world, increased solar irradiation availability throughout the year. Yemen has a long coastline and high altitudes of 3677 m above sea level, making it an ideal location for wind energy generation, with an estimated 4.1 h of full-load wind per day.
This study reviews Yemen’s electricity and energy sector before and after the onset of the conflict that began in 2015 and presents the current state of power generation, transmission, and distribution systems in the country by assessing the negative impact in the electricity sector caused by the ongoing conflict. 2.
According to the International Energy Agency, in 2000, oil made up 98.4% of the total primary energy supply in Yemen with the remainder comprising biofuels and waste (International Energy Agency). Natural gas and coal were introduced into the energy mix around 2008, and wind and solar energies were added around 2015.

Historically, Bulgaria has also been a major producer and exporter of electricity for the surrounding region with a total of 10 inte connectors spread across Romania, Serbia, North Macedonia, Greece, and Turkey.

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible. . Goals that aim for zero emissions are more complex and expensive than NetZero goals that use negative emissions technologies to achieve a. . The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply,. . The intermittency of wind and solar generation and the goal of decarbonizing other sectors through electrification increase the benefit of adopting pricing and load management. . Lithium-ion batteries are being widely deployed in vehicles, consumer electronics, and more recently, in electricity storage. [pdf]
Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.
166MIT Study on the Future of Energy Storage integration, by contrast, are expected to account for only a very small share (approximately 0.5%) of hydrogen demand. Increased demand for “green” hydrogen will drive down the cost of green hydrogen production technologies, eventually making power generation via hydrogen more cost competitive.
Together, the model enhancements opened the door to exploring many new research questions about energy storage on the future grid. Across all modeled scenarios, NREL found diurnal storage deployment could range from 130 gigawatts to 680 gigawatts in 2050, which is enough to support renewable generation of 80% or higher.
The model results presented in this chapter focus on the value of energy storage enabled by its arbitrage function in future electricity systems. Energy storage makes it possible to defer investments in generation and transmission, reduce VRE curtailment, reduce thermal generator startups, and reduce transmission losses.
The latter enables time-shifting of energy supply and is function- ally central to the other grid applications provided by energy storage. The model results presented in this chapter focus on the value of energy storage enabled by its arbitrage function in future electricity systems.
"We found energy storage is extremely competitive on an economic basis, and there are rapidly expanding opportunities for diurnal storage in the power sector," said Will Frazier, lead author of Storage Futures Study: Economic Potential of Diurnal Storage in the U.S. Power Sector.
