A drive-over steel basin - in standby the module stands about 20 mm high.

Contain the battery.
Protect the vessel.
PyroPool is a containment concept built into the vessel's car deck, designed to rise around a battery-electric or plug-in hybrid vehicle (BEV/PHEV), cool the battery from below and keep contaminated suppression water under control.
Concept-stage system for technical evaluation and vessel-specific engineering.

01 / The risk
The problem has changed
EV fires no longer follow the old playbook.
When an EV battery pack ignites, the fire burns extremely hot, releases hazardous gases and carries a high risk of re-ignition. On a densely loaded vehicle deck, both time and distance are in short supply.
PyroPool forms a fixed basin around the vehicle and confines the fire risk.
02 / The system
Pressure becomes structure
A pool that is almost invisible - until it matters.
Actuate
Trained crew in the required PPE/SCBA open the secured water supply from a safe distance, following the vessel's procedures. Note: the charging cable must always be disconnected from the vehicle before PyroPool is activated.
Contain + cool
Pressurised water expands 3 - 6 stainless-steel layers (configuration adaptable) into a rigid basin around the vehicle.
Manage aftermath
The vehicle and its battery stay in the basin, keeping the fire contained and under control until the vessel reaches port. Only there are the vehicle and the contaminated suppression water moved to HAZMAT handling.

Simple at the point of use
Deep engineering.
Clear operating logic.
The current concept is fully mechanical and does not depend on electrical actuation in an emergency. A sensor-based, electrically actuated system is also in design. The architecture is built for redundancy, marine corrosion resistance and vessel-specific integration.

Engineering status: PyroPool is a concept / prototype-stage system. Full-scale fire testing, classification review, flag acceptance and project-specific stability and safety assessment remain part of the approval path. No MED, SOLAS, CE or class type-approval claim is made.
Patent status: The core invention is protected by granted European patent EP4403234. Patent applications are also pending in Norway, the United Kingdom, the United States and Australia.
Trademark: PYRO POOL is a registered European Union trade mark of HypInno Oy (EUTM No 018855863).
04 / Ship operators
Practical implementation on board
Designed for everyday life on the car deck.
PyroPool is designed around existing marine operations: drive-over traffic, ship fire mains, safe-distance actuation, contaminated-water management and written ISM procedures.
Discuss your needsSimple installation
Fixed to the deck with a vessel-specific piping and fastening design - dry-docking is not necessarily required.
Integrated into the ship's fire main
Mechanical actuation from an existing or equivalent water source.
Controlled containment of fire and water
The basin limits the free spread of both the fire and the suppression water.
Structured approval pathway
Structured path for shipyard, class, flag and fire-safety engineering review.
05 / Investors
An answer to managing EV fire risk
Electrification is scaling.
Fire risk has to scale with it.
PyroPool turns a growing global safety problem into an engineered hardware platform - starting with vehicle decks and expanding to environments where dense EV parking drives up the fire risk.
Request investor briefingRegulatory pull
Operators, insurers and authorities need credible answers for new-energy vehicle risk.
Unique, durable hardware
Materials, forming, weld quality, redundancy and vessel integration create a real engineering moat.
Scalable hardware
A vessel can carry as many basins as it needs - one per vehicle. One vessel holds many parking positions and one operator runs many vessels; the opportunity is not limited to a single ship, operator or country.
A clear path to commercial potential
Unique hardware, full-scale testing, a pilot installation and approval milestones together open the way to realising that potential.
