The landslide of lithium-ion batteries making it to market signifies that fires brought on by them are set to surge, says the chief industrial and product officer of Power Vault, who warns that solely suppliers who put security first will “survive”.
“The quantity of lithium-ion that has been deployed and will probably be deployed is gigantic,” Marco Terruzzin, a mechanical engineer who joined Swiss- and US-based Power Vault in 2019 and beforehand labored for RWE amongst others, tells Recharge. “The variety of fires will go up exponentially.”
“If there’s a hearth in an remoted substation that’s one factor,” he mentioned. “However in case you have a hearth in a dense, closely populated space that may turn out to be rather more problematic.”
Power Vault is maybe finest identified for its gravity power storage system, which makes use of cranes to haul big bricks into the air to retailer power after which launch them for discharge – much like the method of large-scale pumped-hydro storage.
However for short-term power storage wants the corporate additionally makes use of lithium-ion batteries, which dominate the sector. A current evaluation from consultancy McKinsey discovered that demand for them may develop 30% yearly up till 2030, when the provision chain would attain $400bn in worth with a market dimension of 4.7TWh.
Their market dominance displays the very fact they pack the most important punch on the lowest weight of any comparable know-how that has reached scale at market. However for all their success they’re tormented by an inclination to overheat and catch hearth – and even explode.

This runs all the way in which up from cell phones, that are barred from the maintain of planes for that very purpose, by e-motorbikes and e-scooters – “you discover what number of… catch hearth in residences,” mentioned Terruzzin – to large-scale power storage services.
There’s a “tendency within the trade” in line with Terruzzin to solely think about worth.
In terms of power storage services, he mentioned that solely corporations that may “continuously” monitor their batteries with the correct working and upkeep techniques will have the ability to keep away from fires.
The prevalence of fires with such batteries signifies that he thinks solely corporations which can be “adapting one of the best practices to handle thermal runaway will survive and succeed on this market.”
That’s the reason Terruzzin mentioned his firm has dozens of individuals engaged on its proprietary software program monitoring and diagnostics instruments to stop fires from breaking out within the first place.
The security points round lithium-ion batteries are why Terruzzin says that main utilities are taking a look at power storage techniques like gravity storage that may function for many years with out operating the danger of a “hazardous occasion.”
He confused that Power Vault, which can also be eying inexperienced hydrogen, has a “sensible” and “pragmatic” method, fairly than attempting to market one particular answer.
For instance, Power Vault additionally sees inexperienced hydrogen as an answer for extra-long length power storage. Nevertheless, Terruzzin mentioned they “combine and match” this with batteries – similar to in a single take care of Pacific Gasoline and Electrical within the US – as a result of if the grid goes down resulting from a blackout you want an power supply to “kick in rapidly”.
He warned that Europe is clearly “over-relying” on the Chinese language provide chain in the case of the batteries, one thing that can trigger it hassle “in the long run”.
Power Vault has tried to “keep away from that subject” by investing within the manufacturing of batteries within the US, which he added now has a “clear set of incentives” to develop a home marketplace for them by its landmark Inflation Discount Act handed final 12 months.
Broadly talking he believes lithium-ion is right here to remain. At present, he mentioned it has the “finest match, least price” for storing power between two and 4 hours – “that could be a matter of truth.”
“It is going to keep dominant as a result of it’s a very versatile answer.”
