What ETW Energy Technology does
ETW Energietechnik GmbH is a privately held German energy technology company headquartered in Moers, founded circa 1999, that designs, engineers, and manufactures turnkey energy plants as a general contractor / EPC provider. Its product portfolio covers three integrated technology lines: SmartCycle® biomethane plants based on Pressure Swing Adsorption (PSA) for upgrading biogas, landfill gas, sewage gas, and natural gas to grid-quality biomethane; Blockheizkraftwerke (CHP) gas engine systems for combined heat and power generation with reported efficiency up to 90% and CO2 reduction up to 60% versus separate generation; and SmartCool® LCO2 plants for liquefying the CO2 by-product of biogas upgrading into food-grade liquid CO2 with claimed 100% methane and CO2 recovery and 0.30 kWh/Nm³ energy consumption. The company operates 4,400 m² of manufacturing halls in Germany, holds 500+ realised projects, 500 MW total installed motor capacity, and 60,000 Nm³/h aggregate biogas treatment capacity, and maintains 6 service locations across Germany with 150,000+ spare parts in stock and remote monitoring as standard.
ETW serves four primary customer verticals: agricultural biogas operators (often in plant-bundling configurations), landfill operators (where high N2 content makes PSA the viable upgrading route), industrial energy consumers in food production, cement/lime, and stainless steel (using CHP for baseload power and process heat), and municipal wastewater treatment plants. Named reference customers include Stadtwerke Duisburg (Germany), a European cement and lime producer in Aisemont (Belgium), food production facilities in Ratingen and Kursk, a wastewater utility in Stammheim, a landfill operator in Taranto (Italy), and agricultural biogas facilities in Lethbridge (Canada) and Rhede (Germany).
The business model is project-based EPC delivery complemented by a recurring aftermarket service stream. Revenue is generated through one-time equipment sales of custom-engineered plants, ongoing maintenance and service contracts tied to the installed base, and spare parts supply. Sales is primarily direct enterprise field sales in Germany, extended internationally through a network of 7 regional sales partners covering Australia, France, UK, Italy, Kazakhstan/Uzbekistan, Spain, and Brazil. The company is managed by Carsten Weiss and Marco Weiss as Managing Directors, is privately held with no disclosed external investors, and has approximately 160 employees.

Revenue model
- EPC / General contractor equipment sales: ETW acts as general contractor / EPC (Engineering, Procurement, Construction) provider delivering turnkey energy technology plants. Revenue is generated through one-time project-based sales of biomethane plants, CHP plants, and CO2 liquefaction systems. Each project is custom-engineered and includes design, manufacturing, installation, commissioning, and sometimes construction works. The company maintains 4,400 m2 of manufacturing halls in Germany.
- Maintenance and service contracts: ETW provides ongoing maintenance, remote monitoring, incident management, and emergency service for its installed base of plants. The company operates its own service network across Germany with multiple service locations. Over 150,000 spare parts are kept in stock. Service contracts include regular maintenance, overhauls, spare parts supply, and emergency response. This represents a recurring revenue stream tied to the installed base of 500+ realised projects.
- Spare parts supply: Supply of original spare parts for gas engines, compressors, turbochargers, pumps, and peripheral equipment. Spare parts include wear and tear parts, consumables, replacement engines, and complete peripheral components. Parts can be delivered by courier to customer sites. Revenue from parts supply is part of the broader service and maintenance business.

Products and services
- SmartCycle Biomethane Plants SmartCycle biomethane plants use ETW's proprietary pressure swing adsorption (PSA) technology to upgrade biogas, landfill gas, sewage gas, or natural gas into biomethane (over 99.5% CH4) suitable for injection into the natural gas grid or use as vehicle fuel. Designed to handle variable gas quantity and quality and supports plant bundling scenarios where multiple smaller biogas plants feed into one central upgrading facility. Delivered to industrial energy producers, agricultural biogas operators, landfill operators, and municipal wastewater utilities.
- Blockheizkraftwerke (Combined Heat and Power Plants) ETW's CHP plants combine gas engines (e.g., MWM TCG series, MTU 16V4000) with heat recovery to deliver up to 90% total efficiency and up to 60% CO2 reduction versus separate power and heat generation. They support grid parallel and island operation, achieve fast start-up under 3 minutes from 0-100%, and integrate exhaust heat into industrial processes at over 400°C. Designed for industrial energy consumers in manufacturing, food and beverage, cement and lime production, and municipal utilities.
- SmartCool LCO2 CO2 Liquefaction Plants SmartCool LCO2 plants liquefy the CO2 by-product from biogas upgrading into food-grade liquid CO2 per EIGA standard (up to 99.9% purity). The integrated system achieves 100% CO2 recovery and 100% methane recovery with the lowest reported energy consumption of 0.30 kWh/Nm3, and can be fully integrated with ETW's SmartCycle biomethane plants without unnecessary interfaces. Delivered to biomethane producers seeking food-grade liquid CO2 monetization.
- PowerTEC Power Packs PowerTEC is ETW's mobile or modular power pack offering within its portfolio of energy technology solutions, providing containerized or transportable power generation capability for industrial and decentralized energy applications.
