Hydrogen battery, a greener solution to store solar energy

Anicet MBIDAC is a new ecological solution to store energy: the Australian startup Lavo offers the first individual hydrogen battery for domestic use.Less bulky, with fewer toxic components than the current lithium-ion batteries, this recharge remains twice as expensive.

Housing independent of the electrical network without pollution?This could be possible in the future, thanks to the first individual battery which stores electricity in the form of hydrogen.Currently, when a home has solar panels and its occupants want to disconnect from the classic electrical network, you must be able to store electricity generated on sunny days to be able to use the rest of the time.A storage possible only so far using lithium-ion batteries, bulky and full of toxic elements.

A storage capacity three times higher than its size

This new type of battery, more compact and more ecological, will make its hydrogen itself.Just plug it into one side to solar panels and on the other to a water supply.The battery will use the too much electricity to make electrolysis: decompose water with hydrogen and oxygen.This hydrogen will then be stored in the battery.And on bad weather days, it will be used to generate electricity.

Lavo, an Australian startup, is the first to offer this type of battery.Advantage on lithium-ion: it offers a capacity three times greater than equivalent size.A small wardrobe one meter by one meter sixty, for example, corresponds to the equivalent of two days of electricity consumption of a home.

A high price

This innovation, sometimes some drawbacks.The price first of all: 20.000 €, twice as much as lithium-ion.And then there remains the problem of the inflammability of hydrogen.Even if the case is well protected, there is always risks of explosion in the event of a fire.
