One of many buzziest startups trying to disrupt the clear power storage sector has an modern new technique: promoting common outdated batteries similar to all people else.
Over the previous few years, Power Vault raised lots of of hundreds of thousands of {dollars} from traders on the premise that it might do one thing that extensively out there lithium-ion batteries couldn’t: retailer clear electrical energy, cheaply, for a lot of hours at a time. Cracking the code on “long-duration power storage” would flip variable wind and solar energy into reliable, round the clock assets. The Division of Power considers this significant to cleansing up the electrical energy sector and simply opened up $350 million to check out rising long-duration applied sciences.
Power Vault shortly established itself as one of many best-funded contenders on this rising area, and it rode that momentum to a public itemizing on the New York Inventory Alternate in February.

However on a quarterly earnings name earlier this week, Power Vault’s iconoclastic gravity storage idea — elevating and reducing multi-ton monoliths to retailer and launch power — didn’t take heart stage. The corporate continues to be vying to disrupt the battery-dominated grid storage market, as promised. However within the meantime, it’s additionally promoting a lot of standard battery storage. And a few inexperienced hydrogen served alongside standard battery storage. However largely simply battery storage.
Traders who handed over lots of of hundreds of thousands of {dollars} to create a groundbreaking new expertise could be shocked by the corporate’s swing again to a broadly accepted and extensively out there different. Moderately than calling this a pivot to batteries, CEO Robert Piconi framed it as “expertise diversification throughout power storage mediums.”
“There is no such thing as a silver bullet in power storage — most prospects will likely be deploying a number of types of short- and long-duration storage supporting completely different functions,” he stated on the decision with traders. “No power storage firm is offering prospects this kind of flexibility right this moment, besides Power Vault.”
That final level is plain.
The grid storage market is awash in opponents shopping for batteries and inverters and turning them into energy vegetation to satisfy hovering demand for clear power storage. Lots of them have carried out it for years, racking up observe information within the area and buyer testimonials to bolster their gross sales pitch. However remarkably, all these worthy opponents have uncared for to enrich their battery choices with precommercial metal edifices to boost and decrease purpose-built monoliths.
If any market exists on the intersection of those two wildly completely different merchandise, Power Vault can personal it by default, since nobody else is attempting.
Lengthy-duration storage breakthrough nonetheless forthcoming
When Power Vault unveiled itself in 2018, Piconi promised to “speed up the tempo” of the clear power revolution by utilizing gravity to retailer renewable electrical energy for longer durations than is feasible with the lithium-ion batteries in the marketplace right this moment.
The plan was easy: erect AI-guided six-armed cranes to stack 35-ton blocks many tales excessive, then quickly decrease the monoliths to the bottom to launch saved power. On the time, Power Vault stated it could set up its first business venture for Tata Energy Firm in 2019.
Power Vault produced artists’ renderings the likes of which storage wonks had by no means earlier than seen, though conceptually, this method resembles pumped hydro storage, the old-school however extremely efficient method for storing giant quantities of electrical energy by pumping water to an elevated reservoir. Inside a 12 months, Power Vault raised a $110 million funding from SoftBank’s Imaginative and prescient Fund, the biggest fairness funding in a grid storage {hardware} firm on the time (a report presently held by the latest $450 million elevate for Kind Power, which stays centered on commercializing its long-duration storage expertise).
Quick-forward to right this moment: Power Vault is publicly listed on the New York Inventory Alternate, holds $275 million within the financial institution and calls itself the “preeminent power storage firm.” It simply hasn’t constructed that first commercial-scale block-stacking super-crane but, and by no means will.
Earlier this 12 months, Power Vault ditched the cranes in favor of extremely engineered metal honeycombs many tales tall, which purportedly will use AI to flow into multi-ton blocks internally at excessive velocity whereas staying upright and never falling down. This huge development is dubbed “EVx,” quick for Power Vault, to not be confused with the ever present abbreviation for electrical automobiles.
The corporate does have a couple of those new-and-improved EVx techniques kicking round. It broke floor on a Texas set up with main world developer Enel Inexperienced Energy, Piconi stated. When full, this method will ship 18 megawatts/36 megawatt-hours of storage capability.
