“…In fact, according to the European energy strategy, in 2019, the Italian government approved the Energy and Climate Plan [6] in which three main targets were defined: (i) a reduction of the primary energy consumption, i.e., -43% compared to the European reference scenario [7], (ii) an increase in renewable production up to 30% of the gross final energy consumption and (iii) a reduction of 40% of greenhouse gas emission. Almost 55.4% of the estimated electricity consumption in 2030, i.e., 16.1 Mtoe, is planned to be covered by renewable sources, in particular, 6.3 Mtoe (39.9%) and 3.4 Mtoe (21.5%) should be produced, respectively, by photovoltaics and wind turbines.…”

New technological solutions are required to control the impact of the increasing presence of renewable energy sources connected to the electric grid that are characterized by unpredictable production (i.e., wind and solar energy). Energy storage is becoming essential to stabilize the grid when a mismatch between production and demand occurs. Among the available solutions, Power to Hydrogen (P2H) is one of the most attractive options. However, despite the potential, many barriers currently hinder P2H market development. The literature reports general barriers and strategies to overcome them, but a specific analysis is fundamental to identifying how these barriers concretely arise in national and regional frameworks, since tailored solutions are needed to foster the development of P2H local market. The paper aims to identify and to analyze the existing barriers for P2H market uptake in Italy. The paper shows how several technical, regulatory and economic issues are still unsolved, resulting in a source of uncertainty for P2H investment. The paper also suggests possible approaches and solutions to address the Italian barriers and to support politics and decision-makers in the definition and implementation of the national hydrogen strategy.

Global warming plays an increasing role in our world, as the share of renewable energy sources in the overall production of electricity has witnessed exponential growth over the past years. Consumer demands are required to be met at any moment at a feasible price. However, storing energy in hot and arid climate regions is a sensitive matter as it is critical to consider appropriate technologies to implement for avoiding unnecessary causalities caused by extreme temperatures. This study compares 13 different energy storage methods, namely; pumped hydro, compressed air, flywheels, hot water storage, molten salt, hydrogen, ammonia, lithium-ion battery, Zn-air battery, redox flow battery, fuel cells, supercapacitors, and superconducting magnetic storage to be implemented in hot arid regions in terms of water usage, energy density, location dependency, and temperature degradation. A survey was conducted based on prior criteria to compare all 13 energy storage methods. The study concluded that the highest rankings for energy storage techniques are obtained for; Zn-air battery, superconductors, and flywheels with overall rankings of 7.18, 6.73, and 6.61, respectively. In contrast, some of the rankings are very close to each other implying the potential application of several methods in hot climates.

The Electrification ratio in Indonesia is 89.10%, which means there are 7, 245,728 of 66, 489,400 households don't have access to Electrical Energy Sources (EES). Kupang Regency is one of the Regency in Indonesia which has a low electrification ratio. 29,542 of 78,109 households haven't access to EES spread over 29 villages (electrification ratio of 62%). Solar Photovoltaic in Kupang Regency 5 MWp capacity has been operating but directly connected (On-Grid) to the State Electricity Company (PLN), it is not able to help rural communities that are difficulties to reach due to its geographical conditions. The aim of this research was design the electrification ratio optimization model with the consideration of CO2 emission reduction using Solar Photovoltaic. The method of research using dynamic modeling approach. The result of the research shows that electrification ratio can be achieved optimum estimated in 2020-2021 if the addition of capable power each year 4,000 kW. The addition of capable power 2,000 kW/year, can reach the optimum electrification ratio in 2023-2024 and if the addition of capable power is only 1,000 kW/year, the optimum electrification ratio can be achieved in 2030-2031. Diversification of DPG into Solar PV can reduce CO2 emissions by 98.8%.
