“…The total surplus of wind energy includes the energy effectively fed into the electrolyser and the two fractions that cannot be used for hydrogen production: the power exceeding the electrolyserrated power and the power lower than the electrolyser idling power (assumed equal to 20% of the stack-rated power) [19,20].…”

Abstract. The potential to produce hydrogen from renewable resources is of considerable interest due to fears over man-made climate change and resource depletion. Hydrogen produced from renewable resources can be used to generate electricity through a fuel cell, or for other uses in a hydrogen economy. There are a number of potential system configurations for hydrogen production from electrolysis including grid connected and standalone. In remote locations, stand-alone configurations are of interest, and may prove more economically viable than grid connected systems. In this paper a standalone wind -hydrogen generation system is designed and proposed to take advantage of an electrolyser capable of operating at very low power levels. A dynamic model of the system is presented, along with a maximum power point (MPPT) control algorithm of the system. The potential yield of such a wind-hydrogen stand-alone system located at the University of Glamorgan's Hydrogen Centre is investigated using wind speed data collected at the site and the performance of the system under variable wind conditions determined.

“…The full benefits of hydrogen will be obtained when is produced from renewable energy sources. Different renewable energy sources have already been studied for electrolyzation, such as wind [2,3] and solar energy [4,5]; the feasibility of these sources to produce hydrogen has been demonstrated, with the main drawback the variability of these sources (see, for example [5], for a detailed feasibility and economical study), and the significant cost of solar hydrogen [6].…”

ElectrolyzersOff-grid systems a b s t r a c tThe aim of this paper is to present and evaluate a proposal for designing an off-grid offshore electrolysis plant powered by wave energy. This plant includes PEM electrolyzers, a Reverse Osmosis system to produce water with adequate conductivity, a compression unit to store the hydrogen for transport, and batteries for temporary storage of electricity for short-time balances. First, the systems that compose the proposed plant are justified and described. Then a proposal for sizing these subsystems is given, based on using buoy-measured data at the expected location and simple mathematical models of the different sections of the plant. Finally the performance of the plant in a specific location is tested in detailed by using measured data, studying the influence of sizing on the expected performance.Copyright ª 2013, Hydrogen Energy Publications, LLC.

It is well known that hydrogen is a clean energy carrier independent of energy sources [1]. The full benefits of hydrogen will be obtained when is produced from renewable energy sources. Different renewable energy sources have already been studied for electrolyzation, such as wind [2,3] and solar energy [4,5]; the feasibility of these sources to produce hydrogen has been demonstrated, with the main drawback the variability of these sources (see, for example [5], for a detailed feasibility and economical study), and the significant cost of solar hydrogen [6]. There are some published works on using reverse osmosis to obtain hydrogen from seawater, involving wave energy for generating the energy for the process [7,8]. There are even patents available that take into account this idea [9,10]. This paper concentrates on offshore systems: the source considered in this work is wave energy as wave converters provide lower variability in the energy production in comparison with other sources [11]. Offshore power links are known to be significantly expensive [12], so the system is here assumed to be fully isolated from the grid: it is parallel to the grid independent wind-hydrogen generation presented in [6]. Thus, power consumption adapts to power production by connecting or disconnecting sections of the electrolyzation plant (following a Smart Grid approach for the microgrid in the plant), and using a temporary storage of electricity for shorttime balances and increase of autonomy (that is a relevant issue in offshore installations). Automatic cleanings and maintenance operations are scheduled in the sections that are temporarily disconnected, to improve overall efficiency. Compared with previous proposals [8e10], this paper concentrates on using commercially available components that are already tested in the marine environment. Special * Corresponding author.
