Hydrogen as a fuel of the future is the talk of the town in energy markets. Pros and cons of green versus blue hydrogen, capacity building plans, new production technologies, you name it, researchers are working on it. Hydrogen can be used as a fuel in fuel cell vehicles—still very expensive—and for heating—blended with natural gas. One other thing it can be used for is renewable energy storage. Earlier this week, the Sydney Morning Herald reported on a company, LAVO, that had developed what is essentially a hydrogen battery that can take in electricity produced by solar panels and store it in the form of hydrogen, to be released on demand. The battery, the size of a fridge, contains an electrolyzer that breaks water down into hydrogen and oxygen. The hydrogen is then stored in a set of canisters full of hydride—a fibrous metal alloy. The battery can be […]
