GreenFarm

What GreenFarm does

GreenFarm ApS is a Danish climate-and-energy hardware company founded in 2022 in Sabro, Denmark, by Frank Wennerberg, a former CEO of Combigas with more than two decades of biogas-industry experience. The company sells and services modular, on-farm biogas plants under the GreenFarm™ brand that use anaerobic digestion to convert livestock manure into electricity, heat, and a more plant-available fertilizer for on-farm consumption, with surplus electricity sold back to the grid. Its customers are primarily small-and-mid-sized dairy, beef, pig, and mixed livestock farms, plus at least one agricultural school (Gråsten Landbrugsskole), across Denmark, Norway, Lithuania, and Poland.

The core technology is the GreenFarm™ Biogas Plant, a scalable system configurable from 3,000 to 20,000 m³ of slurry per year and offered in standardized configurations from GF 15-1 (one gas engine) to GF 90-6 (six gas engines) with combined heat and power (CHP) units. Each installation runs on standard anaerobic digestion driving gas-engine CHP stacks, with optional add-ons including a Battery System for energy arbitrage and grid-outage resilience and a CO2 capture module supplied through partner Welltec. GreenFarm bundles the equipment with a managed support contract that includes daily remote plant monitoring, on-site and phone servicing, leak testing, and monthly operational reports, and the company advertises a 5-month order-to-operation timeline.

The business model combines a one-time capital sale of each installation with a recurring managed-services contract (remote monitoring, maintenance, optimization) and a transaction-fee component via grid sales of surplus electricity. Distribution is sales-led and direct-to-farmer, supported by regional market managers (e.g., Market Manager Norway Jørn Schanche), trade-show presence at NutriFair, agricultural media coverage, LinkedIn and Facebook presence, a monthly newsletter, and a "GreenFarmer" peer community of installed customers. In 2024 the company raised a double-digit million DKK investment from Skovgaard Energy (a 10% equity stake), established a Norwegian subsidiary, expanded into Lithuania and Poland, and added the Welltec CO2-capture partnership. Chairman of the board is Patrick Feller.

Revenue model

1. Biogas Plant Sales and Installation: GreenFarm sells and installs complete biogas plants to livestock farmers. The plants are scalable and tailored to each farm's needs. Revenue comes from initial capital investment for plant construction and installation.
2. Ongoing Support and Service: Continuous revenue through service contracts including remote monitoring, maintenance, repairs, and optimization. Customers can choose between full service packages or partial self-service with annual condition assessments. Monthly operational reports included.
3. Energy Sales: Farmers can sell surplus electricity produced by their biogas plants back to the power grid, generating additional income on top of self-consumption savings.

Core offering

GreenFarm designs, sells and installs scalable on-farm biogas plants (GreenFarm™ Climate and Energy Plants) that convert livestock manure into renewable electricity and heat for on-farm consumption, with surplus energy sold to the grid. Plant sizes range from 3,000 to 20,000 m³ of slurry per year, complemented by optional battery storage, CO2 capture modules, and recurring monitoring/maintenance service contracts.

Product overview

GreenFarm offers a unified product portfolio centered on the GreenFarm™ Biogas Plant — a scalable, modular biogas energy system for livestock farms that converts manure into electricity and heat. The core system is complemented by optional add-ons including a Battery System for energy storage and flexibility, and CO2 Capture Technology for carbon monetization. Comprehensive support and monitoring services are provided throughout the plant lifecycle. The product range scales from small installations (3,000 m³ slurry/year) to large installations (20,000 m³/year), with facilities operational across Denmark, Norway, and Lithuania.

Functional benefit

Products and services

• GreenFarm Biogas Plant (GreenFarm™ Climate and Energy Plant) A scalable on-farm biogas plant that converts livestock manure into renewable electricity and heat for on-farm consumption, with surplus sold to the power grid. The system includes gas engines, digesters and a control system, and is configurable from 3,000 to 20,000 m³ of slurry per year (GF 15-1 through GF 90-6), with a 5-month order-to-operational deployment timeline. Targeted at livestock farmers with cattle and pigs in Northern Europe.
• Battery System An optional battery storage add-on for GreenFarm biogas plants that increases energy supply security and flexibility by storing excess energy for later use, providing backup power during outages, and enabling energy arbitrage (buying electricity when prices are low and selling when prices are high).
• GreenFarm Support and Monitoring Service Comprehensive monitoring and support service for GreenFarm plants, including daily remote plant monitoring, phone/online/on-site support, dry matter and gas measurement, leak testing, operational optimization, and monthly operational reports. Customers can choose full service packages or partial self-service with annual condition assessments.
• CO2 Capture Technology CO2 capture technology that allows farmers to collect and monetize CO2 emissions from their biogas plants, providing a potential additional revenue stream on top of energy production. Provided in collaboration with Welltec.

Direct peers

• PlanET Biogas: German modular biogas plant manufacturer targeting farm and small industrial customers with similar scalable AD systems; competes for the same mid-size farm biogas segment.
• Weltec Biopower: German manufacturer of modular stainless-steel biogas plants for farms and municipalities, with overlapping on-farm AD/CHP technology and customer profile.
• BTS Biogas: Austrian modular farm-scale biogas plant specialist offering standardized containerized AD units comparable to GreenFarm's GF series.
• Combigas: Danish on-farm and industrial biogas plant developer where GreenFarm's founder Frank Wennerberg was previously CEO. Directly comparable in modular AD/CHP technology and farm-target customers.

Broad incumbents

• Xergi: Danish biogas EPC contractor with comparable anaerobic digestion technology and farm/utility project delivery; broader scope than GreenFarm's modular on-farm focus.
• Nature Energy: Largest Danish industrial-scale biogas/RNG producer with similar manure-to-energy technology but operates large centralized plants rather than on-farm modular systems; same Nordic regulatory and feedstock environment.
• EnviTec Biogas: German biogas plant builder covering small farm-scale to large industrial AD plants; comparable in modular engineering but broader geographic and project footprint.

Regional players

• Bigadan: Danish biogas operator with multiple large plants processing manure and industrial waste; same Danish/Nordic manure feedstock supply chain and regulatory regime.
