Spain’s Ecowill Engineering has joined forces with French company McPhy to develop a hydrogen production and storage plant near Bogotá, Colombia, powered purely by renewable energy, reports Fuel Cell Today. Water hydrolysis yields hydrogen from electricity produced by wind or solar power.
The gas can then be used immediately, or, if power supply outstrips demand, be stored in solid form as magnesium hydride in containers using McPhy’s technology. The process allows large amounts of hydrogen to be kept at low pressure (around 10 bar), making it relatively easy to transport.
The stored hydrogen can be used to produce electricity through a combustion engine, a fuel cell or a gas turbine, as required. There will be six containers on the Colombian site, which together will store the equivalent of nearly 23MW of energy, according to a McPhy company representative.
