RNG

Renewable Natural Gas

Transform waste into pipeline-quality renewable natural gas. Replace fossil natural gas with drop-in RNG for heating, power generation, or vehicle fuel.

How RNG Works

The X-150 produces syngas that undergoes methanation to convert CO and H₂ into methane (CH₄), then upgrading to pipeline-quality natural gas.

1

Syngas Production

Gasification produces clean syngas (CO + H₂) from waste feedstock with minimal tar and contaminants.

2

Methanation

CO + 3H₂ → CH₄ + H₂O reaction converts syngas to methane over nickel catalysts at 300-400°C.

3

Gas Upgrading

CO₂ removal via membrane separation or PSA, plus H₂S and moisture removal to meet pipeline specs.

4

Grid Injection

RNG is compressed, odorized, and injected into natural gas pipelines or used on-site.

Real-World Applications

RNG configuration enables renewable gas supply for heating, power, and transportation

Residential & Commercial Heating

Gas utilities inject waste-derived RNG into existing pipelines, supplying renewable gas to homes and businesses without infrastructure changes, decarbonizing heating sector.

Problem Solved: Fossil natural gas dependence, heating emissions

Benefit: Drop-in replacement, renewable gas certificates

Industrial Process Gas

Manufacturing facilities, food processors, and chemical plants use waste-derived RNG for boilers, furnaces, and process heating, replacing fossil natural gas with renewable supply.

Problem Solved: Volatile natural gas prices, carbon emissions

Benefit: Price stability, waste valorization, carbon neutrality

Vehicle Fuel (CNG/LNG)

Fleet operators compress RNG to CNG or liquefy to LNG for heavy-duty trucks, buses, and marine vessels, providing carbon-negative transportation fuel from waste.

Problem Solved: Diesel emissions, fuel costs, carbon intensity

Benefit: Low Carbon Fuel Standard credits, fleet decarbonization
