“…Modern PHS plants have a cycle efficiency of about 80% [54,55], and allow the utilization of excess electricity from base-load power sources (such as coal or nuclear) or fluctuating RES to be saved for use during periods of higher demand. Reservoirs used in these systems are generally smaller compared to conventional hydroelectric dams of similar power capacity and their generating periods are often less than half a day.…”

“…Chile has vast amounts of solar and wind resources which are increasingly being harnessed to replace fossil fuel generation. The impact of large scale integration of these variable RES for grid-level electricity storage was evaluated by [55]. In this study, a cost-based linear optimization of the Chilean electricity system was developed to analyse and optimize various RES generation, transmission and energy storage scenarios until 2050.…”

“…Results of this study showed that for the base scenario of decommissioning of aging coal plants and no new coal and large hydro generation, the generation gap can be filled by PV, concentrated solar power and flexible gas generation resulting in a drop of 78% in carbon dioxide emissions. Integration of PV for on-grid storage increases the solar PV fraction which consequently leads to a 6% reduction in operation and investment costs by 2050 [55].…”

Currently, Kenya depends mainly on oil, geothermal energy and hydro resources for electricity production, however all three have associated issues. Oil-based electricity generation is environmentally harmful, expensive and a burden to the national trade balance. The rivers for hydropower and their tributaries are found in arid and semi-arid areas with erratic rainfall leading to problems of supply security, and geothermal exploitation has cost and risk issues amongst others. Given these problems and the fact that Kenya has a significant yet underexploited potential for photo voltaic (PV)-based power generation, the limited—although growing—exploitation of solar PV in Kenya is explored in this paper as a means of diversifying and stabilising electricity supply. The potential for integration of PV into the Kenyan electricity generation mix is analysed together with the sociotechnical, economic, political, and institutional and policy barriers, which limit PV integration. We argue that these barriers can be overcome with improved and more robust policy regulations, additional investments in research and development, and improved coordination of the use of different renewable energy sources. Most noticeably, storage solutions and other elements of flexibility need to be incorporated to balance the intermittent character of electricity generation based on solar PV.

“…There are several possibilities to realizing such an objective. For example, some argue for more rigorous and extensive implementation of energy efficiency, a broader mix of energy options and the development of carbon capture and storage (Maximov et al 2019). Nevertheless, the scale of the challenge is such that it cannot address one sector of society alone (Atilgan and Azapagic 2016).…”

Clean energy denotes the array of fuel options obtained from mostly renewable, low emissions sources such as bioenergy, direct solar energy, geothermal energy, hydropower, ocean energy, and wind energy with minimal impact on the environment or environmentally friendly (IPCC 2011).There are several ways to defining energy efficiency. There is the ecosystem-related approach whereby energy efficiency refers to the capacity to safeguard the integrity of the ecosystem while providing optimum energy services (Omar 2008). Other explanations denote energy efficiency, as the use of minimum energy to supply the same level of energy. It is hence one approach to limit human greenhouse gas (GHG) emissions. Furthermore, energy efficiency quantifies the conversion of energy from one form to another, with no regard for impacts outside the process.

“…All the electric system's levels should be equipped with distributed storage systems: pumped hydro stations, compressed air energy storage (CAES) systems, power-to gas and power-to-heat technologies [2], together with batteries, flywheels, supercapacitors, superconducting magnetic energy storage (SMES), pumped thermal energy storage (PTES) [8][9][10]; while some storage technologies are more suitable for large size installations (e.g., pumped hydro and CAES) [11], batteries have a wide-ranging use and can be installed both in medium and high voltage networks and at building level. As highlighted by Günther et al [12], in some applications it is profitable to combine different storage technologies, some power intensive and others energy intensive, in order to improve the range of possible services provided by the whole storage system.…”

The exploitation of distributed renewable energy sources leads to a low-carbon energy transition, mainly based on the optimal integration of hydro, PV and wind power plants with the remaining high-performance fossil-fuel power stations. In the last twenty years, European Union (EU) countries have shown a significant increase of the power installed in new PV and wind power plants, together with the refurbishment of small and medium size hydro stations. In particular, in Italy, PV and wind energy production has strongly increased and nowadays there are regions characterized by a very green energy mix. In this new scenario, energy storage becomes a viable solution to mitigate the variability of renewable energy sources thus optimizing the network operation. The present paper is focused on the Liguria region, in the North of Italy and in particular on the Bormida Valley where nowadays more than the half of the annual electricity consumption is covered by the renewable energy local production. The paper describes the current energy situation and proposes an optimization tool to investigate the possibility of installing new PV and wind power plants, as well as energy intensive storage units based on sodium-sulphur batteries; moreover, different scenarios are analyzed through the definition of economic and environmental key performance indicators.
