Integrated biomethane and agricultural energy

Turn Agricultural Waste into Reliable Green Energy.

Convert manure, crop residues and food-processing waste into biomethane, electricity and useful heat through modular gas treatment, upgrading, CHP, BESS and remote energy management.

Renewable electricity
Process heat
Grid-quality biomethane
Digestate and fertilizer
Start from the waste and the load

One circular-energy platform for five agricultural scenarios.

The right route depends on feedstock stability, gas quality, electricity and heat demand, grid access, transport economics and the value of digestate. The project should begin with this operating reality, not a membrane or generator quotation.

Livestock farms

Manure treatment, odor control, power, hot water and digestate management for dairy, pig and poultry operations.

Food processing

Breweries, slaughterhouses, sugar, starch and food plants with organic wastewater and process-heat loads.

Palm oil and agro-industry

POME, crop residues and shared utilities for agricultural processing parks and export-oriented production.

Municipal organics

Food waste, wastewater sludge and landfill gas upgraded for local power, heat or gas networks.

Cold chain and greenhouses

Dispatchable energy for irrigation, refrigeration, crop drying, greenhouse heating and remote communities.

Choose the product of value

Four routes from the same biological molecule.

Select a route to see how the gas, power and storage modules change with the customer's commercial objective.

Route A

Use biogas or biomethane as dispatchable farm energy.

Suitable for weak-grid farms and processing sites with continuous electricity, hot-water or steam demand. Gas quality and engine compatibility determine whether direct biogas use or full upgrading is preferred.

Raw biogasGas cleaningGas engine / CHPElectricity + heat
Route B

Produce biomethane for pipeline injection or contracted gas supply.

The upgrading and measurement system is engineered against the receiving network's gas-quality, pressure, metering and sustainability requirements.

Route C

Move renewable gas to vehicles or customers beyond the pipe.

Compression or liquefaction can serve agricultural fleets, logistics, islands and distributed gas users when scale and transport economics support the route.

BiomethaneCompression / liquefactionStorageBio-CNG / Bio-LNG
Route D

Coordinate renewable gas, solar and storage around agricultural production.

Biomethane generation supplies firm power, PV reduces daytime fuel use, BESS manages transients and the EMS prioritizes cold storage, irrigation, greenhouse and processing loads.

Reference performance and project evidence

Use proven equipment ranges as a starting point, then engineer the real gas.

Reference capacities support early screening. Final performance follows raw-gas composition, contaminants, moisture, temperature, pressure, flow variability, pretreatment and the required product-gas specification.

400 / 800 / 1,200Nm³/h standard raw-biogas upgrading reference capacities.
200–3,000Nm³/h refrigerated drying reference range; adsorption packages can address higher project-specific flows.

Feedstock & Biomethane Assessment

Send the gas and the load, not just a project name.

We will use the feedstock, raw-gas condition, energy demand and target product to prepare an initial process boundary and modular delivery route.

First output: recommended route, missing data, preliminary module chain and local-integration questions.

Performance and compliance are assessed project by project. Submission creates a project inquiry for CIMC ENRIC's solution team.

Frequently asked questions

Questions that determine the real project route.

What is the difference between biogas and biomethane?

Raw biogas normally contains methane, carbon dioxide, moisture and trace contaminants. Biomethane is upgraded gas with carbon dioxide and contaminants reduced to a specification suitable for the selected power, grid or transport application.

Can biogas be used directly for farm power?

Yes, when the gas quality is compatible with the engine and the site has adequate gas cleaning, drying, storage and controls. Upgrading to biomethane may be preferred when the gas will also be injected, transported or stored at higher pressure.

Can a farm combine biomethane, solar PV and battery storage?

Yes. A hybrid microgrid can use biomethane generation as dispatchable power, PV for daytime fuel displacement, BESS for transient support and an EMS to coordinate agricultural loads.

Can an existing biogas plant be upgraded in stages?

Yes. Gas drying, desulfurization, compression, membrane upgrading, storage, generation and controls can be configured as separate modules and connected to an existing digestion and gas collection system.

Can biomethane equipment be assembled locally in Europe?

Projects can be structured for complete packaged delivery, skid-by-skid delivery or local secondary assembly with qualified partners. The final route must be engineered against applicable certification, hazardous-area, pressure-equipment, origin and local installation requirements.

Can individual treatment and power modules be supplied separately?

Yes. Standardized mechanical, electrical and control interfaces allow selected modules to be supplied, expanded, replaced or integrated with existing customer equipment.

How can local EPC and service partners participate?

Depending on contract scope, local partners may support structural fabrication, piping, electrical balance of plant, final assembly, installation, certification coordination, spare parts and lifecycle service.

What data is required for an initial biomethane assessment?

The first assessment requires feedstock type and daily volume, raw biogas flow, methane concentration, hydrogen sulfide, moisture and contaminants, pressure, temperature, seasonal variation, energy demand, desired gas use and project location.

European delivery routes must be confirmed against the requirements applicable to the final scope and location. Useful official references include the European Commission's biomethane policy page, CE-marking guidance and applicable hazardous-area and pressure-equipment rules.
