Description
The technology for the generation and usage of hydrogen as a fuel is established however as present the best
way to store the hydrogen is to pressurise the gas to 350 bar and above. That is 350 times atmospheric
pressure. This has cost and safety considerations. Handling high pressure hydrogen requires thick and heavy
metal cylinders or bulky composite cylinders. Electrolysers driven by electricity from renewables or from the
national grid can readily generate hydrogen but this is at low pressures. Thus mechanical gas compressors are
needed to compress the gas to above 350 bar. Such mechanical compressors are expensive and require
constant maintenance and storing large quantities of hydrogen at high pressure requires blast zones. Being
able to store the majority of gas at low pressure utilising metal hydride (MH) solid state stores not only is safer
but it requires much less volume of space. Also fuel cells (which convert hydrogen and oxygen to water and
electricity) operate at these low pressures too. So for certain stationary applications storing hydrogen utilisng a
low pressure MH store makes sense and this project will build a prototype and explore this market.
