Production of hydrogen from magnesium hydrides hydrolysis

Kinetically Controllable Hydrogen Generation at Low Temperatures by the Alcoholysis of CaMg2‐Based Materials in Tailored Solutions

“…Recently, various effective methods such as ball‐milling, alloying, changing the aqueous solution composition, and catalyst doping have been adopted to improve the hydrolysis properties of Mg‐based materials. The tailoring of the components of solutions, such as the introduction of organic acids, inorganic acids, or saline solutions, has been efficient to accelerate the hydrolysis kinetics of Mg/MgH 2 , whereas the addition of salt or acid may be harmful to the environment and corrode equipment. Moreover, a temperature range above 0 °C for hydrogen generation from chemical hydrides using water as a solvent is a serious hurdle for outdoor applications.…”

Electrical power generation with PEM FC using hydrogen supply through Mg-Ni reaction with water

“…Because of its promising utilization for environmentally friendly energy generation without CO 2 emissions, the development of an appropriate carrier where hydrogen would be safely stored is essential [2][3][4]. Hydrogen can be stored either in pressurized, cryogenic tanks or solids capable to ensure reversible absorption/desorption reaction of hydrogen with low energy exchange [1,5,6]. However, storage in high pressure or cryogenic tanks is not suitable for many hand-held applications as it requires massive equipment with additional safety fittings [6].…”

“…On the contrary, gas storage can be excluded if direct hydrogen production is achieved on-site during the reaction between metals, metal alloys, hydrides and water [3,4,[6][7][8][9]. For example, aluminum, magnesium, lithium, zink, boron, beryllium or silicon are successfully applied for in-situ hydrogen generation using the previously mentioned water oxidation of light metals [4,8].…”

“…Particular attention is paid to magnesium (Mg) due to its low density, high capacity, reactivity and abundance in the earth [10,11]. Magnesium hydride (MgH 2 ) offers a great potential for widespread use as its weight yield of hydrogen reaches 6.4% and it can be increased up to 15.2% if water produced in a fuel cell (FC) is used in the reaction again [6]. Therefore, Mg and MgH 2 are used for hydrogen production by the following reactions:…”
