One of the main technical challenges of wind-to-hydrogen production plants is to couple intermittent and variable renewable power sources, such as wind turbines, with an electrolyser. Most hydrogen production concepts rely on electrical storage to smoothen the power input to the electrolyser. In this study, the use of a hydro-pneumatic energy storage system is proposed as an interface between the green, fluctuating electricity supply and the electrolyser. The performance of the proposed solution is analysed and compared to that of a conventional offshore wind-to-hydrogen production plant in order to identify potential advantages and drawbacks. The results of the simulations show that the FLASC energy storage system provides a stabilized, yet green power supply. Short-term fluctuations of the power input to the electrolyser can be avoided. A 70% reduction of the On/Off cycles can be obtained. Moreover, if compared to an offshore wind-to-hydrogen production plant with no storage there is no substantial difference in terms of hydrogen production observed over the analysed period of one year in spite of a 70% round-trip efficiency of the energy storage device.

“…The utilization of renewable energy sources is finding more and more acceptance in society and plays a crucial role in the political and economic situation [4]. In the last 20 years, much effort has been put into developing systems to integrate renewable sources into the current energy system [5]. Gielena et al [6] reported on the acceleration of the energy transition, which would enable two-thirds of the world's energy demand to be supplied by renewable energy sources by 2050.…”

“…The use of renewable energy sources, especially energy storage, has become the focus of intensive research since energy production is strongly influenced by environmental factors (e.g., weather) [5]. Hydrogen, which can be produced from a variety of renewable energy sources, offers an efficient and clean alternative to fossil fuels.…”

“…The use of hydrogen technology in the industry 2 of 22 and the energy sector offers several opportunities and presents a significant challenge. Some works [5,7,8] present complete overviews about the implemented hydrogen-based energy systems for mobile and stationary applications. As reported, there are several challenges to hydrogen as an energy carrier, with cost, efficiency, and durability emerging as the most critical.…”

“…MH-systems are characterized mainly by high operational reliability and high volumetric storage density [9,10]. An important field of application intended for MH-systems are stationary power-to-gas (PtoG) and gas-to-power (GtoP) systems [5]. These integrated systems offer the advantage of producing green hydrogen through electrolysis from renewable electricity and re-converting stored hydrogen into electric power in a fuel cell when needed.…”

A Novel Emergency Gas-to-Power System Based on an Efficient and Long-Lasting Solid-State Hydride Storage System: Modeling and Experimental Validation

In this paper, a gas-to-power (GtoP) system for power outages is digitally modeled and experimentally developed. The design includes a solid-state hydrogen storage system composed of TiFeMn as a hydride forming alloy (6.7 kg of alloy in five tanks) and an air-cooled fuel cell (maximum power: 1.6 kW). The hydrogen storage system is charged under room temperature and 40 bar of hydrogen pressure, reaching about 110 g of hydrogen capacity. In an emergency use case of the system, hydrogen is supplied to the fuel cell, and the waste heat coming from the exhaust air of the fuel cell is used for the endothermic dehydrogenation reaction of the metal hydride. This GtoP system demonstrates fast, stable, and reliable responses, providing from 149 W to 596 W under different constant as well as dynamic conditions. A comprehensive and novel simulation approach based on a network model is also applied. The developed model is validated under static and dynamic power load scenarios, demonstrating excellent agreement with the experimental results.
