“…A high-density and low-cost energy storage technology would provide a key solution for further promoting the utilization of renewable energy around the world. In recent years, the author and their collaborators, as along with some other pioneer researchers, have proposed an energy storage/release concept using H 2 , a renewable energy carrier, based on Mg materials for hydrogen storage, coupled with a solid oxide fuel cell (SOFC) [1][2][3][4][5][6]. This is based on the great advantages of Mg for energy storage application in terms of its very high energy density and the quite low cost of Mg as a raw material.…”

Mg-based materials have been investigated as hydrogen storage materials, especially for possible onboard storage in fuel cell vehicles for decades. Recently, with the development of large-scale fuel cell technologies, the development of Mg-based materials as stationary storage to supply hydrogen to fuel-cell components and provide electricity and heat is becoming increasingly promising. In this work, numerical analysis of heat balance management for stationary solid oxide fuel cell (SOFC) systems combined with MgH 2 materials based on a carbon-neutral design concept was performed. Waste heat from the SOFC is supplied to hydrogen desorption as endothermic heat for the MgH 2 materials. The net efficiency of this model achieves 82% lower heating value (LHV), and the efficiency of electrical power output becomes 68.6% in minimizing heat output per total energy output when all available heat of waste gas and system is supplied to warm up the storage. For the development of Mg-based hydrogen storage materials, various nano-processing techniques have been widely applied to synthesize Mg-based materials with small particle and crystallite sizes, resulting in good hydrogen storage kinetics, but poor thermal conductivity. Here, three kinds of Mg-based materials were investigated and compared: 325 mesh Mg powers, 300 nm Mg nanoparticles synthesized by hydrogen plasma metal reaction, and Mg 50 Co 50 metastable alloy with body-centered cubic structure. Based on the overall performances of hydrogen capacity, absorption kinetics and thermal conductivity of the materials, the Mg nanoparticle sample by plasma synthesis is the most promising material for this potential application. The findings in this paper may shed light on a new energy conversion and utilization technology on MgH 2-SOFC combined concept.

“…

From the standpoints of crucial climate change arising from greenhouse-gas (GHG) emissions, unavoidable depletion of fossil fuels and upcoming stricter environmental regulations on pollutants emissions, seeking other means of power production based on more efficient and environment-friendly operation has become more and more globally important [1,2]. Fuel cell based micro combined heat and power (micro-CHP) is a viable technology to efficiently cater electricity and heat need of residential dwellings [3,4]. This technology can mitigate the greenhouse gas emissions by utilizing the generated heat during the electricity production to address the thermal need of the residential sector.
