Off-grid & microgrid power without diesel

Diesel gen-sets power most off-grid and backup sites today — but they are loud, dirty and tied to a constant fuel-delivery convoy. A multi-fuel PEM fuel cell gives commercial and industrial operators clean, near-silent power that scales from a single remote asset to a full site microgrid (~1 kW to 1 MW), runs on hydrogen, methanol or ethanol, and integrates into OEM equipment. It is zero-emission on hydrogen and far cleaner than diesel on liquid fuels.

The hidden cost of the diesel gen-set

A diesel generator's sticker price hides the real cost: fuel logistics to remote sites, noise that limits where it can run, exhaust and emissions, maintenance of engine parts, and downtime. For an off-grid asset, the fuel convoy alone can dwarf the hardware cost over its life.

Clean, near-silent power

A fuel cell generates electricity electrochemically — no combustion. That means zero local emissions on hydrogen (only water and heat), far lower emissions than diesel on methanol or ethanol, and near-silent operation under ~40 dB. Cleaner and quieter expands where you can site power — near people, indoors, in noise- or emissions-restricted areas.

Off-grid sites & microgrids

For remote and off-grid operations, usable energy per kilogram and refuelling decide the economics. With up to ~15× the energy density of lithium-ion at the system level and over 50% system efficiency in target configurations, a fuel cell carries more power for less weight and runs longer between refuels — paired with renewables and storage, it becomes the dispatchable backbone of a clean microgrid.

Built into your equipment (OEM)

The platform is modular and OEM-integration friendly. Equipment makers can build LEC's stack and MEA into their own products — generators, marine systems, mobile power — adding a clean-energy line under their brand without rebuilding their engineering or supply chain. See the OEM path in our partnership options.

Fuel flexibility for real operations

The same hardware runs on hydrogen, methanol or ethanol. Use hydrogen where it is supplied; switch to liquid methanol or ethanol where hydrogen logistics are impractical. One platform adapts to the fuel reality of each site instead of locking you to a single supply.

Scales from one asset to a whole site

Modular from ~1 kW to 1 MW: power a single telecom tower or remote sensor, or stack modules into a site microgrid for a farm, depot, port or industrial facility. Performance holds from −32 °C to +60 °C, so the same kit works from arctic sites to desert operations.

Frequently asked questions

Is it really zero-emission? On hydrogen, the only by-products are water and heat — zero local emissions. On methanol or ethanol, emissions are far lower than diesel combustion, with no engine exhaust.

Can it replace our diesel backup generator? For many sites, yes — quieter, cleaner and fuel-flexible. For sites where diesel is cheap and abundant and noise/emissions don't matter, diesel may still suit; often the two are combined while sites transition.

Does it work with solar and batteries? Yes. In a microgrid the fuel cell provides dispatchable, weather-independent power alongside renewables and storage — covering the gaps solar and batteries can't.

Can we put it inside our own product? Yes — the stack and MEA are designed for OEM integration. See the partnership types.
