One outage, four systems at risk

High-rise buildings depend on continuous power to keep occupants safe and moving. A single grid outage puts four things at risk at once:

Elevators stop

When grid power drops, elevators can strand occupants between floors and cut off egress for upper-level residents and tenants.

Life safety offline

Fire pumps, smoke control, and stairwell pressurization depend on continuous power to protect occupants and meet code.

Water stops flowing

Domestic water booster pumps lose pressure to upper floors, while sump pumps stop — risking flooding in mechanical spaces.

Access & comfort lost

Security systems, access control, lighting, and HVAC go down, disrupting tenants and building operations.

Automated systems need power too

Modern high-rises run on automated systems that all depend on continuous power — not just the systems above, but the layer of building automation and security that operators rely on every day:

Physical security

Cameras, access control readers, and intrusion detection all need continuous power to keep watching and controlling every entry point.

Access control & entry

Electronic locks and card readers fail-safe or fail-secure when power drops — risking locked-out residents or unsecured doors.

Building automation

Centralized HVAC, lighting and elevator control systems stop responding without continuous power to the building management system.

Communications & alarms

Intercoms, fire alarm monitoring and emergency communication systems depend on the same continuous power.

The Flux Home solution

Flux Home is a solid oxide fuel cell that runs continuously on natural gas to generate primary electricity, paired with battery storage for instantaneous, seamless power — independent of the electrical grid. The process is straightforward: natural gas feeds an electrochemical conversion in the fuel cell stack, battery storage buffers the output for an instant response with no gap, and the building gets continuous uptime for elevators, life safety and water systems alike.

Beyond standby power

Diesel generators and battery-only UPS systems wait for the grid to fail before they respond. Flux Home is already running as the building's primary source, with battery backup for instant continuity:

Sized for high-rise critical loads

Flux Home and Flux Ember are right-sized for the building — from a single riser to whole-building critical load.

Flux Home — single riser or small building critical loads

3 kWContinuous output
<45 dBAAt 10 ft
2'×2'×5'Footprint (W×D×H)
~600 lbsWeight

Ideal for elevator machine rooms, single-riser life-safety loads, or a dedicated mechanical closet.

Flux Ember — whole-building or multi-tower critical load

27 kVAPeak output
288 kWhEnergy available/day
12.6 kW-thUseful heat recovered
29.2 daysRuntime, 1,000 gal tank

Packages generation, battery storage, and thermal recovery in one transportable unit for rooftop or grade-level mechanical yards.

Built for the building site

Compact and quiet enough for a mechanical room, rooftop, or loading dock:

<45dBA at 10 ft
~1Day installation
2'×2'×5'Footprint (W×D×H)
~0.35m³/hr fuel use

120 VAC nominal voltage, up to 40 A current, ~600 lbs, indoor/outdoor rated. Deployed in a mechanical room, rooftop mechanical yard, or loading dock — no new gas service required where natural gas is already on site. Output and fuel consumption vary with site conditions, gas quality and system configuration.

Reliable, visible, in control

Flux Home is a dispatchable, standards-compliant asset built for critical building infrastructure:

Certifications & compliance: UL 1741 (inverter safety for grid support), UL 9540B (battery safety compliance), and EN 50465 (electrical compatibility standard).

Where it fits

Multifamily high-rises

Protect elevators, life-safety systems and water pressure for residents on every floor.

Commercial office towers

Keep tenants working and building systems running through grid disruptions.

Mixed-use developments

Serve retail, residential and office loads from a single dispatchable power platform.

Healthcare & senior living

Meet life-safety power needs where uninterrupted power is most critical.

Never lose power to the building that never stops.
