The World's First Home Hydrogen Battery

By: April Carson

The battery may store three times as much energy as Tesla's Powerwall 2.

Tesla's Powerwall has a long way to go before it can compete with the newest home battery storage system from Australian energy firm Lavo, which does not rely on standard batteries. Instead of using hydrogen as fuel, New Atlas claims, the device uses hydrogen to charge and discharge an electrolyte, similar to how a metal-air battery works.

The objective of both systems is to capture any extra energy generated by solar or wind power installations, as well as provide an emergency supply of power if the grid goes down.

The company has not released many details about the product, but New Atlas says that it will be able to store three times as much energy as Tesla's Powerwall 2. The device is also said to be cheaper to produce than lithium-ion batteries, and will have a lifespan of 10,000 cycles – or about 30 years.

Lavo's enormous battery, which it calls the Green Energy Storage System, is a technically an electrolysis device that can extract hydrogen from water, store it, and then convert it into electricity using a fuel cell similar to a hydrogen car.

The 90 kWh battery has a capacity of 13.5 kWh, which is nearly three times the energy storage of Tesla's current-generation Powerwall 2. That's huge competition in the space, and it shows that Lavo's battery can store enough power for an average family to run its house for two days straight.

Lavo's battery is not only huge, but it's also very intelligent. The company has developed an artificial intelligence-based software platform that manages the battery and its charging/discharging cycles. This ensures that the battery is always operating at peak efficiency and that its lifespan is maximized.

According to Lavo, its system will outlast lithium battery systems because it makes use of hydrogen gas rather than the chemicals in a regular battery. It's also more ecologically beneficial since it uses less rare earth metals.

However, there's also the risk of fire or — in the absolute worst-case scenario — a Hindenburg-style explosion. Lavo claims that any leaks will dissipate quickly, making it "inherently no more dangerous than other traditional fuels such as gasoline or natural gas," according to the company's FAQ.

On the other hand, storing hydrogen gas and then converting it to electricity has some drawbacks. Lavo claims that its "round-trip efficiency is above 50 percent," which is far less than the average lithium ion battery system's.

The device, unsurprisingly, is rather pricey. According to New Atlas, the Energy Storage System costs more than $26,900 and more than three Tesla Powerwall 2s in Australia.

Despite the high upfront cost, Lavo believes that its product is "the most cost-effective solution in the long term." The company cites a variety of reasons for this, including the lack of need for regular maintenance and replacement, as well as the fact that hydrogen is a renewable resource.
