05 Apr Down to Earth: start-up backed by Hong Kong tycoon Peter Lee aims to commercialise battery technology used in space
The start-up’s product can be charged and discharged 30,000 times without rest for 30 years, Chan said. It is fireproof, operable between minus 40 and 50 degrees Celsius and is 90 per cent recyclable.
Global energy storage investment was estimated to have surpassed US$35 billion last year, up from US$20 billion in 2022 and mostly deployed in power grids, according to the International Energy Agency.
The two main applications for high-capacity energy storage today are electric vehicles batteries and utility-scale systems. The latter – which is where EnerVenue is focused – are used in power grids to manage intermittent renewable electricity production, and act as backup power for industrial, commercial and residential buildings.
The nickel-hydrogen system being developed by EnerVenue competes with other grid storage technologies, such as lithium-ion, sodium sulphur, flow batteries and hydro pump, which stores energy by pumping water from a reservoir to another one at a higher elevation.
A year ago, EnerVenue announced that it will build its first 1 GWh factory in the US, on a 73-acre site – the size of 55 football fields – in the state of Kentucky, which will house design, manufacturing and testing facilities.
Subsequent phases of expansion, supported by generous local government tax incentives, could see the company increase its output capacity to over 20 GWh per year, at a total investment cost of over US$1 billion. EnerVenue had over 7GWh of customer commitments, it said at the time.
In late 2021, EnerVenue, co-founded by Stanford University materials science and engineering professor Cui Yi and Lee’s Full Vision, completed US$125 million of series A financing.
The round of fundraising was led by Texan oilfield services firm Schlumberger and drew investment from oil behemoth Saudi Aramco, Beijing-based investment firm IDG Capital, and Full Vision, to fund battery research, marketing and production scale-up in China and in the US.
“Back in 2018, we sat down with professor Cui in Stanford University to talk about the next generation of batteries,” Chan said. “He told us there is a solution, and then he and my team wrote on a piece of paper the intellectual properties involved, how the company will work and we formed EnerVenue with just five people.”
