“…How to design and use CAES for load levelling in the electricity supply has been analysed and discussed for several decades in academic literature [1][2][3][4]. In recent years, CAES has primarily been seen as a means of improving the integration of fluctuating wind power into the electricity supply [5][6][7][8][9] or it has been compared to other electricity storage options [10,11]. However, so far the optimisation of CAES operation on electricity spot markets has not been dealt with.…”

“…Fuel cells are seen as the key technology to a future hydrogen economy [20]. Storage of all types (pumped hydro, molten salts and rocks, electric vehicle fleets), and combined heat and power are essential components improving the integration and capacity credits of variable renewable energy resources at high renewable penetration rates, in that they enable the temporal and spatial relocation of excess power [21][22][23][24][25]. However, marine renewable devices are behind their terrestrial counterparts in terms of maturity [26], and the commercialisation of nuclear fusion appears to be at least four decades away [27].…”

Electricity is perhaps the most versatile energy carrier in modern economies, and it is therefore fundamentally linked to human and economic development. Electricity growth has outpaced that of any other fuel, leading to ever-increasing shares in the overall mix. This trend is expected to continue throughout the following decades, as largeespecially rural-segments of the world population in developing countries start to climb the "energy ladder" and become connected to power grids. Electricity therefore deserves particular attention with regard to its contribution to global greenhouse gas emissions, which is reflected in the ongoing development of low-carbon technologies for power generation. The focus of this updated review of electricity-generating technologies is twofold: (a) to provide more technical information than is usually found in global assessments on critical technical aspects, such as variability of wind power, and (b) to capture the most recent findings from the international literature. This report covers eight technologies. Seven of these are generating technologies: hydro-, nuclear, wind, photovoltaic, concentrating solar, geothermal and biomass power. The remaining technology is carbon capture and storage. This selection is fairly representative for technologies that are important in terms of their potential capacity to contribute to a lowcarbon world economy.

Ireland with its resource of wind has the potential to use this natural resource and sustain the country's power needs for the future. However, one of the biggest drawbacks to renewable energy generation, particularly wind generated electricity is that it is an intermittent and a variable source of power. Even at the "best" sites wind varies dramatically from hour to hour and minute to minute. This leads to two main problems: 1) When the wind drops below a lower limit or goes above a higher limit the turbine can shut down and electricity is not produced. 2)Energy is not stored when there is an excess of electricity generated on site. Because of these problems wind power has a very low capacity credit and backup power is needed to handle the large fluctuation of production.This paper introduces the energy system of Ireland and the targets that Irish operators are to achieve in the next decade. A review of energy storage options for Ireland is outlined including the use of hydrogen and fuel cell technology. It is concluded that a project similar to the Norwegian Utsira wind / hydrogen project could be piloted in Ireland and a site similar to Dundalk Institute of Technology could be used to demonstrate and test the system. Going forward to achieve high levels of renewable energy generation, similar distributed wind / hydrogen hybrid systems could reduce the need for curtailment of wind farms, save wasted energy, reduce backup power, reduce transmission losses, generate large revenue by selling power at peak times, ensure security of supply and reduce the need for costly interconnects to Europe.
