Procedure for optimal design of hydrogen production plants with reserve storage and a stand-alone photovoltaic power system

Exploring Green Hydrogen Applications and Optimization Methods in the Power Sector: A Comprehensive Review

“…Although battery energy storage systems offer a potential remedy, the considerable costs associated with such systems remain a formidable barrier [11]. A promising solution involves green hydrogen production, where hydrogen serves as an energy storage system [12,13,14,15,16,17]. This approach holds the potential to address these challenges and facilitate the increased integration of RESs.…”

Hazards assessment and technical actions due to the production of pressured hydrogen within a pilot photovoltaic-electrolyser-fuel cell power system for agricultural equipment

“…Produced hydrogen acts as an energy vector that can accumulate the photovoltaic energy exceeding the current demand, and it can be used to generate power later by means of fuel cell. Hydrogen production systems powered by stand-alone photovoltaic generators can contribute to improve living standards in rural areas not yet supplied with electric grid, avoiding expensive investments for a single electric grid implementation (Valdés et al, 2012). These plants can operate reliably under dynamic solar irradiance and dynamic loads, even though the global efficiency of such systems is very low (less than 5%) mainly owing to the operating performance of the photovoltaic panels (Maclay et al, 2011).…”

“…Presently worldwide hydrogen production is set up on fossil sources using natural gas reforming process or coal gasification (Mueller-Langer et al, 2007) but hydrogen can be also manufactured by biomass thermal processing or by biological methods (Redwood et al, 2009). Water electrolysis is the only one without carbon dioxide emissions in atmosphere and it produces zero emissions if linked to electricity obtained by renewable sources (Chai et al, 2012;Valdés et al, 2012). Hydrogen produced with this process is stored in pressurized gas cylinders and can be used to supply electricity for various farming applications.…”

Sizing of stand-alone photovoltaic/wind/diesel system with battery and fuel cell storage devices by harmony search algorithm

“…In recent years, investigation of stand-alone hybrid systems based on renewable sources and hydrogen power has attracted significant attention [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. In the literature, Belfkira et al [3] have proposed a method for size optimization of a WG/PV/diesel system.…”
