CROSTORION headquarters
Our own EMS and trading system: the same battery earns more, because what decides when it charges is ours.
Hover any point
Utility-scale storage
A dependable turnkey package for stand-alone BESS projects — containers, conversion, controls and the market side under one contract.
Wind
Storage sized to the farm, on a PCS built for the way wind ramps, with an EMS that trades what it firms.
Solar farm
Storage sized to the array, and an EMS that trades: the plant stops being a price-taker at midday and sells into the evening.
Storage at the resort
Bought outright or taken as Storage as a Service — the same cabinets either way, with the commercial model chosen to suit the hotel.
Shopping centre and offices
Retail floors and offices on one connection: bought outright or taken as Storage as a Service, with the cabinets sized on the building’s own peak — which is where the demand charge is won.
Mobile storage
Storage and charging for fleets, delivered under a PPA: cars, buses and heavy electric trucks powered where they work, with the supply guaranteed.
Wellsite power
An integrated supply for sites the grid does not reach: storage, conversion and control as one package, sized on what the wellsite actually draws.
Quarry, mine and building site
The same integrated supply wherever the connection is weak or absent — mining and construction plant carried by storage instead of by diesel alone.
Data centre
Storage sized for a load that never drops — and, where you want the whole supply, a fixed PPA price that stands up against anything else on the table.
Battery recycling
Every pack we supply has a documented end: what still holds capacity goes back out in second-life cabinets, the rest is processed under licence — and the Battery Regulation paperwork and chain of custody stay with us.
Off-grid energy solution
No cable to the mainland: generation, storage and control sized as one system, so the island runs on its own all year.
Grid connection
Frequency regulation: the fleet answers the system operator, and the site is paid for holding the network steady.
Storage at the factory
Bought outright or taken as Storage as a Service — the same cabinets either way, with the commercial model chosen to suit the plant.
Home storage
5 to 30 kWh on the wall, with an EMS the household watches and runs from a phone.
Charging station
Storage and charging built as one system — and the same PPA-backed supply for fleets: cars, buses and heavy electric trucks.
Marine charging system
Shore-side charging and storage for vessels, available under a PPA.
Electric vessels
Semi-solid-state battery systems for ships: the safest cells we can put to sea, packaged and serviced for marine duty.

The difference
Hardware is the easy part
A battery manufacturer sells hardware. We take responsibility for the whole system — the device, the savings on your bill, and the value the market pays for capacity that stands ready.
We shape the solution with you, sized to your load profile — and if you already know the battery you want, you can ask for it directly.
One contract
Local service
Daily load profile · the battery covers the peaks
Facility consumption
Peak covered by the battery
Grid connection limit
Your daily consumption, and the peak the battery covers before it reaches the grid connection limit.
What it does for you
One battery, four outcomes
A smaller bill
It charges when electricity is cheap — from the grid or your roof — and covers you through the expensive hours.
HowA capped peak
The handful of hours that set your grid charges get flattened automatically — the billed peak stops climbing.
For businessPower through outages
When the grid drops, the battery takes over automatically — production keeps running, the lights stay on.
HowIncome while it waits
Under our own electricity-trading licence the battery works for the market when you don't need it — value on top of the saving on your own bill.
The market side
ESaaS — Storage as a Service
You don't have to buy a battery
We finance, install, own and operate the system on your site. No upfront investment — what the battery saves and earns is measured against your own meter, and shared.
One contract covers the hardware, the software, the service and the market access. And because we earn when your battery earns, our interests are yours.
What we do
From battery to market — one partner
From a single cabinet to a licensed market participant — four ways in, one team behind all of them.
Energy storage
Five classes, from 5 kWh stackable batteries to 2.75 MWh+ utility containers. LiFePO₄, liquid-cooled, IP65.

Made in Europe
European hardware. Our own engineering. Data in the EU.
Hardware assembled in Europe, engineering in-house, and all operational data hosted on servers in the EU — GDPR-compliant by design. For an industrial or public buyer, that is a stronger position than a lower-cost import.
- Assembled in the EU — own assembly in its final commissioning phase.
- Engineered in the EU — our own EMS and optimiser code.
- Data resident in the EU — operational data never leaves the EU.
The platform
See your savings as they happen
The client portal shows real savings in real time — and trading activity as a coloured bar inside your own consumption graph.
You see exactly when your battery worked for the market, with nothing to decode. Three layers sit behind it: device, site and market.
