Green Technology GlobalGTG's large-scale infrastructure work is built around utility-constrained data centers, industrial sites and agricultural operations. FLUX takes the same off-grid thinking and scales it down — to homes, remote properties, and the mobile power that emergency responders need on short notice. Both products are built on the same core technology: a solid oxide fuel cell (SOFC) that converts natural gas directly into electricity and useful heat, quietly and continuously, without combustion noise or a generator's duty cycle.
FLUX Home: primary power, not backup
FLUX Home is a compact solid oxide fuel cell that runs continuously on the natural gas already piped to a property, generating a subscriber's primary electricity supply on site — independent of the electric grid. The grid stays connected as a backstop; it's no longer the primary source. That's a different design goal than a standby generator, which sits idle until the grid fails. FLUX Home is meant to be the day-to-day power source, dispatched and monitored by the utility.
- Noise: under 45 dBA at 10 feet — quiet enough to site close to a home without becoming a nuisance.
- Footprint: 2′ × 2′ × 5′, roughly 600 lbs, indoor or outdoor rated.
- Installation: about a day, tying into the existing gas service line at the meter — no new distribution pipe.
- Fuel use: roughly 0.35 m³/hr of natural gas, delivering up to 40 A at 120 VAC.
- Certifications: UL 1741 (inverter safety for grid support), UL 9540B (battery safety) and EN 50465 (electrical compatibility), with remote Wi-Fi telemetry for utility monitoring and control.
The unit stays a utility-controlled, dispatchable asset — offered to the homeowner as a rate-based or subscription appliance rather than a customer-owned generator.
FLUX Ember: containerized power that moves with the mission
FLUX Ember packages generation, battery storage, controls and thermal-energy recovery into a single transportable 20-foot container, designed to establish resilient on-site power at temporary or infrastructure-constrained locations — disaster response, recovery operations, temporary medical facilities and mission command posts among them.
- Output: 15 kVA continuous, 27 kVA peak, with up to 288 kWh of energy available per day and 12.6 kW-th of useful heat recovered for space heating or hot water.
- Noise: under 50 dBA at 3 feet — a meaningful difference from a diesel genset running next to a hospital tent or temporary housing.
- Fuel flexibility: runs on natural gas, CNG, PNG, bio-CNG or methane, with fuel tank options from 120 to 1,000 gallons.
- Runtime: scales directly with tank size — about 4.5 days on a 120-gallon tank up to roughly 29 days on a 1,000-gallon tank, all without a grid tie or a fuel truck inside the deployment window.
Because generation, storage and thermal recovery all ship in one container, FLUX Ember sites and connects at the point of need, runs continuously, and relocates as the mission moves — rather than requiring separate equipment trailers to be assembled on site.
How this connects to GTG's larger infrastructure work
FLUX isn't a separate company bolted onto GTG's data center and water business — it's the same distributed-power philosophy applied at a different scale. The core argument for a data center operating its own micro-grid is the same argument for a homeowner or emergency response team running FLUX: dependence on a single, centralized source of power is a risk, and there's real value in owning generation that doesn't go down when the grid does.
Who FLUX is for
- Homeowners, gas utilities and builders looking to deliver resilient, on-site primary power without new distribution infrastructure.
- Remote-site operators who need continuous primary power without running a transmission line.
- Emergency management and recovery teams who need power — and useful heat — that can be staged and deployed quickly after grid loss.
If your situation touches any of the above, the fastest path forward is the same one GTG uses for larger projects: describe the site, the load, and the timeline, and let the engineering team map it to the right configuration.
