Brown Gas augmentation — on-demand electrolysis, complete combustion, zero high-pressure storage. Here is exactly how UDJAN works.


What is Brown Gas

Brown Gas —
not hydrogen alone

Brown Gas is a specific mixture of hydrogen (H₂) and oxygen (O) produced by electrolysis of water. Unlike pure hydrogen, Brown Gas contains the oxygen required for its own combustion — it burns completely and cleanly alongside conventional fuels.

When introduced into a combustion chamber — whether a boiler firebox or a diesel engine's air intake — Brown Gas acts as a catalyst that improves the combustion of the primary fuel. Unburnt fuel is reduced, heat release is more complete, and exhaust emissions fall measurably.

UDJAN uses Brown Gas, not pure hydrogen — which means no high-pressure storage tanks, no gas cylinders, and no compressed hydrogen transportation at any point in the system.

⚠ Why no storage is the key safety advantage

High-pressure hydrogen storage and transportation carry significant risk and regulatory complexity. UDJAN eliminates both entirely — the gas is generated on-demand by electrolysis and consumed immediately in the same breath. There is nothing stored, nothing transported, and nothing that can leak at pressure.

HHO
Brown Gas = 2H₂ + O (by volume)
2H₂O → 2H₂ + O₂
electrolysis of distilled water
Brown Gas + Fuel → More complete combustion
co-combustion with diesel / solid fuel
H₂ content ~66% by volume
O content ~33% by volume
Ignition point Very low — burns completely
Storage required None — generated on demand
Transport required None — used at point of generation
Burns completely alongside primary fuel Brown Gas ignites easily at low temperature and burns completely — leaving no unburnt residue. It acts as an accelerant for the primary fuel, ensuring more complete combustion of every litre of diesel or kilogram of solid fuel.

The Process

Four steps from water to savings

The complete cycle from distilled water input to cleaner combustion output.

01

Water in

Distilled water is fed into the UDJAN electrolysis unit. No acids, no additives.

02

Electrolysis

DC current splits water into Brown Gas (H₂ + O) at low pressure. No compression.

03

Gas enters air intake ↓

Brown Gas flows directly into the combustion air stream — boiler or engine — alongside existing fuel.

04

Complete combustion

Brown Gas burns completely with primary fuel. Cleaner exhaust. Better efficiency. Less fuel consumed.


The Difference

UDJAN vs conventional hydrogen

Why on-site Brown Gas generation is categorically safer and simpler than stored hydrogen.

✗ Stored / transported hydrogen

High-pressure cylinders — explosion and leak risk
Requires specialised transport and handling permits
Regulatory compliance for storage at site
Pure hydrogen — requires precise air-fuel ratio control
Infrastructure investment before any fuel saving begins

✓ UDJAN Brown Gas — on-demand

Zero high-pressure storage — generated and consumed instantly
No transportation permits needed — water is the only input
No special regulatory approvals for on-site storage
Brown Gas contains its own oxygen — burns completely at any ratio
Retrofit in hours — savings begin from the first operating cycle

Advantages

Why customers choose UDJAN

Every advantage is measurable and verifiable at installation.

Retrofit in hours, not days

A full installation — from first bolt to first operational cycle — is completed by a UDJAN technician in 4 to 8 hours. There is no extended downtime, no factory shutdown, no multi-day installation crew. Your operation resumes the same day.

🌿

Burns completely alongside present fuel

Brown Gas co-combusts with your existing fuel — diesel, HSD, or solid fuel. It does not replace the fuel; it augments it. The result is a more complete burn of every unit of primary fuel, with measurably less unburnt carbon in the exhaust.

🚫

No storage. No transportation. No risk.

This is UDJAN's most important safety advantage. High-pressure hydrogen storage at industrial sites is hazardous and heavily regulated. UDJAN eliminates storage and transportation entirely — the gas exists for milliseconds between generation and combustion.

🔨

Zero engine or boiler modification

Internal components are never touched. UDJAN attaches externally. Engine cylinder heads, piston assemblies, combustion chambers, and boiler fireboxes are unchanged. Existing manufacturer warranties remain fully intact.

📈

Immediate, measurable savings

Fuel consumption reduction is visible from the first full operating cycle after installation. Stack temperature drops, exhaust opacity reduces, and fuel metering shows less consumption — all within the first shift of operation.

😇

Portable and scaleable

UDJAN units are compact, self-contained, and can be moved between machines or scaled up by adding units in parallel. A single installation can serve one boiler; multiple units can serve an entire generator fleet or industrial plant.
