It is a new ecological solution for storing energy: the Australian startup Lavo offers the first individual hydrogen battery for domestic use.

Less bulky, with fewer toxic components than current lithium-ion batteries, this recharge is however twice as expensive.  

Housing independent of the electricity network without pollution?

This could be possible in the future, thanks to the first individual battery that stores electricity in the form of hydrogen.

Currently, when a home is equipped with solar panels and its occupants want to disconnect from the conventional electricity grid, it is necessary to be able to store the electricity generated on sunny days in order to be able to use it the rest of the time.

Storage so far only possible using lithium-ion batteries, bulky and packed with toxic elements.

Storage capacity three times its size

This new type of battery, more compact and more ecological, will manufacture its own hydrogen.

Just connect it on one side to the solar panels and on the other to a water supply.

The battery will use the overflow of electricity for electrolysis: breaking down the water into hydrogen and oxygen.

This hydrogen will then be stored in the battery.

And on bad weather days, it will be used to generate electricity.

Michelin, Renault, Faurecia… Why are the French betting on hydrogen?

Lavo, an Australian startup, is the first to offer this type of battery.

Advantage over lithium-ion: it offers three times the capacity of equivalent size.

A small cabinet of one meter by six feet, for example, corresponds to the equivalent of two days of electricity consumption of a household.

A high price

However, this innovation has some drawbacks.

The price first of all: € 20,000, which is twice as expensive as lithium-ion.

And then there is the problem of the flammability of hydrogen.

Even if the case is well protected, there is always a risk of explosion in the event of a fire.
