Power that shows up before the grid does.
Metryon's platform converts fuels you can already buy — propane, natural gas, diesel — into clean electricity through a hydrogen fuel cell, and pairs it with battery storage to meet large-scale peak demand. No combustion. No waiting years for an interconnection upgrade. Deployed and supported in the U.S. by ULXI.
Performance figures are engineering design targets for the current platform generation, pending independent field validation. We'll show you the data behind every number.
The problem we solve
Electrification is adding load faster than the grid can absorb it. Fleet depots need megawatts for overnight charging; feeders and transformers are maxed; interconnection and upgrade queues run years, and peak-demand charges punish every kilowatt drawn at the wrong hour. Diesel generators can fill the gap — at the cost of noise, soot, NOx, and permits nobody wants to fight for.
Metryon's answer: generate on-site at high efficiency from fuels with existing supply chains, buffer with DC-coupled storage, and dispatch exactly when demand peaks — behind the meter, off-grid, or alongside the grid as relief capacity.
How it works
Fuel → hydrogen → fuel cell → 800 V DC, with battery storage handling the surges. The architecture, step by step.
Grid balancing & peak demand
Peak shaving, interconnection bridging, and dispatchable distributed capacity — why generation-plus-storage beats either one alone.
Applications
Fleet & EV charging depots, utilities, commercial facilities and data centers, off-grid sites, and defense & tactical vehicle power.
Technology & environment
What "clean" means here — precisely. Emissions profile, efficiency, noise, and the solid-carbon roadmap.
We're selecting a limited number of U.S. sites for validation deployments with independent measurement. Early sites shape the spec.
Hydrogen on demand.
Electricity without combustion.
Hydrogen is the cleanest fuel a fuel cell can eat — but shipping and storing it is expensive and the fueling network barely exists. Metryon sidesteps that: the platform makes its own hydrogen, on site, from ordinary fuels, the moment it's needed.
Generation + storage: two jobs, one system
Peak demand is really two problems wearing one name. A site needs energy (kilowatt-hours over the whole peak window) and power (instantaneous kilowatts when a dozen vehicles plug in at once). Neither generation nor batteries alone solves both economically — together, each does what it's best at:
SOFCs run happiest at steady output, at high efficiency, for as long as there's fuel — hours or days, no duty-cycle penalty, no oversizing for the worst minute of the day.
DC-coupled storage on the same 800 V bus absorbs step changes instantly — vehicles plugging in, motors starting, cloud-edge swings — then recharges from the fuel cell between peaks.
Fast chargers and battery packs are native DC. Generating directly at 800 V DC skips conversion stages a genset-plus-rectifier setup needs — fewer losses, fewer parts, cleaner power.
Predictive control shapes when the system generates, stores, and serves — following your tariff, your duty cycle, or your utility's dispatch signal. Remote monitoring and service contracts keep uptime accountable.
Compared to what you'd otherwise deploy
| Option | Strengths | Where it falls short for peak duty |
|---|---|---|
| Diesel genset | Low capex, familiar | ~30–40% efficient; soot, NOx, noise; permit friction; heavy service burden |
| NG/LPG genset | Cheaper fuel than diesel | Still combustion — noise, emissions, service-heavy |
| Battery-only | Quiet, instant response | Expensive and bulky for long-duration peaks; still needs grid energy to refill |
| Grid upgrade | Permanent capacity | Years of interconnection queue and construction; high, sunk cost |
| Metryon + storage | 50–60% efficiency target; quiet, no combustion; fuel-flexible; deploys in months; redeployable | Earlier-stage platform; higher capex than a genset — pilot data will make the TCO case site by site |
Deployment
- Containerized and modular — from a single 50 kW charging unit to 20+ chargers per site; add capacity as demand grows.
- Fuel your way — pipeline natural gas where it exists; delivered LPG/CNG tanks where it doesn't. Existing fuel logistics, no new infrastructure.
- Relocatable — bridge one site's gap, then redeploy the asset when its permanent grid connection lands.
- Heat recovery option — capture usable heat (CHP) for buildings, wash bays, or process loads to raise total fuel utilization well beyond electrical-only efficiency.
Flatten the peak. Skip the queue.
Every large electric load has the same shape problem: a few hours a day define the whole bill — and the whole interconnection request. Serve those hours from on-site generation and storage, and the grid sees a smaller, calmer customer.
Five ways sites use it
1 · Peak shaving, behind the meter
Dispatch during your utility's peak window to cut demand charges and time-of-use exposure. The battery catches the spikes; the fuel cell carries the plateau.
2 · Interconnection bridging
Your load is ready years before your grid upgrade. Deploy now, operate independent of the feeder, and hand load back to the grid when the wires arrive — then redeploy the asset.
3 · Non-wires alternative
For utilities: place dispatchable capacity at a constrained substation or feeder instead of (or ahead of) reconductoring — relocatable as constraints move.
4 · Dispatchable distributed capacity
Enroll in demand response and capacity programs: a fleet of fuel-fed, fast-responding sites the operator can call on, independent of weather.
5 · Microgrid anchor & resilience
Grid-optional by design: the same system that shaves your peak carries the site through an outage — quietly, and without a diesel plume.
Why this pairing balances the grid
- Firm, fuel-fed energy. Unlike solar-plus-storage, output doesn't depend on weather or season — the peak is served every day it occurs, from fuel with a mature supply chain.
- Long-duration by nature. Batteries alone get expensive past 2–4 hours. A fuel cell runs as long as there's fuel — so multi-hour evening peaks and multi-day events cost fuel, not battery capex.
- Right-sized, not worst-cased. Generation is sized for the energy plateau, storage for the surges — instead of oversizing either one for the single worst minute of the year.
- Grid-friendly profile. Capped, predictable draw makes the site easy to interconnect and easy to plan around — smaller service, calmer feeder, happier utility.
We'll model the peak-shave, size generation vs. storage, and show the demand-charge math for your tariff — before any commitment.
Where it earns its keep
Same platform, five jobs. Modules are sized and fueled per site — a single 50 kW charger to multi-megawatt clusters.
Charge the fleet the grid can't feed yet flagship use case
Electrifying a bus or truck depot can multiply its power demand overnight — literally: the whole fleet charges in the same window. Utilities routinely quote multi-year timelines for upgrades that size. Metryon puts an 800 V DC charging plant on the depot pad, fed by LPG/CNG tanks or pipeline gas, with storage smoothing the plug-in surges.
- School bus fleets: quiet, no diesel soot or fumes where children board — plus predictable fuel logistics districts already understand.
- Transit & municipal fleets: bridge depots waiting on permanent power lines (a ten-bus off-grid charging deployment of exactly this kind is in advanced discussion with major transit operators in Israel today); scale chargers with the electrification schedule.
- Logistics & last-mile: add charging at leased facilities where landlord-side upgrades aren't an option.
Capacity you can place, dispatch, and move
Peak load growth is arriving faster than distribution capex can. Containerized generation-plus-storage gives planners a deployable asset: relieve a constrained feeder this summer, support a substation through its rebuild, firm a fast-charging corridor — then relocate it when the constraint moves. A proof-of-concept program with a national electric utility is in advanced negotiation to validate exactly this stationary application.
- Non-wires alternative with months-not-years deployment.
- Dispatchable and weather-independent — fueled capacity, not forecast capacity.
- 800 V DC native — pairs directly with utility-scale EV charging programs.
Tame the demand charge, keep the racks on
For large C&I loads, a handful of peak hours set the monthly bill — and for data centers, the grid connection itself is now the scarcest resource in the industry. Behind-the-meter generation with storage caps billed demand, adds firm capacity the feeder doesn't have to supply, and doubles as resilient power that doesn't need a diesel permit or a smoke plume. Optional heat recovery serves buildings and process loads, pushing total fuel utilization well past electrical-only efficiency.
Grid-quality power where there is no grid
Telecom towers, rail signals and crossings, construction and roadworks — lighting towers, temporary traffic signals, surveillance — mining, events, and emergency charging for stranded EVs. Anywhere the alternative is a diesel genset droning through the night, a quiet, low-maintenance, fuel-flexible unit with storage does the same job with no soot, near-zero NOx, and remote monitoring instead of site visits.
Quiet power on logistics fuels development track
Military vehicles carry the same peak problem in a harder wrapper: sensors, comms, and mission systems that need hours of power — where an idling engine or a droning genset gives the position away and burns fuel doing almost nothing. An electrochemical power unit changes the signature equation.
- Silent watch & on-board auxiliary power: run mission loads with the engine off — low acoustic and thermal signature, no exhaust plume, no idle hours on the powertrain.
- Runs on the fuels the logistics chain already moves: diesel-fueled operation is in the platform's core fuel set, and the SOFC family has demonstrated operation on heavy logistics fuels — aligned with single-fuel-forward doctrine rather than fighting it.
- Expeditionary & base power: containerized generation + storage for forward positions, command posts, and charging electrified tactical and support vehicles — the same peak-shaving architecture, deployed where there is no grid at all.
- Honest status: this is a development track, not a shipping product line. Defense integrations are scoped case-by-case with the U.S. program; validation and ruggedization requirements are defined with the customer.
Clean, said precisely.
"Zero emissions" gets thrown around loosely in this industry. We'd rather tell you exactly what changes when you replace combustion with electrochemistry — and show the data as validation progresses.
What no-combustion actually buys you
Air quality
No soot or particulates. Near-zero NOx and CO. The pollutants that trigger health concerns and permit fights come from flames — there is no flame here. Fuel is converted electrochemically in the cell.
Carbon
Meaningfully lower CO₂ than engine generators — higher conversion efficiency means less fuel burned per kWh. Today the process still emits CO₂; we won't tell you otherwise. The roadmap below is how that changes.
Noise & siting
Low noise and vibration — no reciprocating engine. That means friendlier neighbors, simpler permitting paths, and viability in places a genset can't go: schoolyards, hospitals, urban depots, nighttime work zones.
Metryon's next platform stage processes fuel by pyrolysis so its carbon exits not as CO₂ gas, but as solid carbon — a stable, storable, potentially saleable material (the same principle behind methane-pyrolysis "turquoise hydrogen"). When validated, it converts the platform's remaining emissions story into a by-product revenue line. We flag it clearly as roadmap: pilot customers will see the lab evidence under NDA and the validation plan.
Efficiency, with the system boundary stated
| Metric | Figure | Boundary / status |
|---|---|---|
| Electrical efficiency | >50–60% | Fuel-to-electricity, design target for the stationary platform; independent validation is part of every U.S. pilot |
| Total fuel utilization (CHP) | Substantially higher | Electrical output plus recovered usable heat, where a site can use it — boundary and load point quoted per project |
| Reference points | ~30–40% · ~35–45% | Typical diesel and NG/LPG genset electrical efficiency, for comparison |
We quote efficiency with its boundary (electrical vs. combined heat and power), fuel, and load point — and we put third-party measurement in the pilot scope. If a number ever arrives without its boundary attached, ask us for it.
Under the hood
- Solid-oxide fuel cell (SOFC) — the fuel-cell family suited to reformed hydrocarbon fuels and stationary duty, led by a team including a published SOFC materials researcher focused on rapid-startup, thermal-shock-resistant cell design.
- On-demand hydrogen — reformer + purifier make fuel-cell-grade hydrogen on site, so there's no hydrogen storage, trucking, or fueling infrastructure anywhere in the chain.
- Smart control & predictive intelligence — dispatch optimization against tariffs and duty cycles; remote monitoring; service contracts with uptime accountability.
- Materials & durability engineering — cell and stack work aimed squarely at the startup-cycling and lifetime demands of real peak-duty operation.
