What 2G Energy does

2G Energy AG is a German manufacturer of modular combined heat and power (CHP) cogeneration systems headquartered in Heek, North Rhine-Westphalia. Founded in 1995, the company designs and produces gas-engine CHP units across a 20–4,500 kW output range, with overall efficiencies of 85% to over 90% in the 20–550 kW segment. Its product portfolio includes the agenitor, avus, aura, and g-box CHP lines, afilia water- and air-sourced heat pumps (added through the 2023 acquisition of NRGTEQ), containerized power plants, the GreenCube compact modular unit, and Gas2Power solutions. Systems are fuel-flexible across natural gas, biogas, propane, and hydrogen, with a H2-ready platform demonstrated in a UK-first trial at Kirkwall Airport in October 2025.

The company sells engineered, project-specific industrial systems primarily through direct enterprise sales, supplemented by a global partner/service network across 17 subsidiaries and a North American rental division (2G Energy Rental NA) launched December 2025. Revenue is generated through one-time equipment sales (CHP, heat pumps, container solutions), recurring service and maintenance contracts, and rental/leasing arrangements, with a digital service layer anchored by the proprietary I.R.I.S. AI-based malfunction prediction system. Customer segments are diversified across agriculture, data centers, healthcare, hospitality, industrial manufacturing, municipalities, and renewable energy/biogas, with over 10,000 systems installed worldwide.

In May 2026, 2G secured the largest order in company history — a multi-year, low-triple-digit megawatt contract for containerized power generation systems from a confidential North American data center customer — marking a strategic pivot toward hyperscale digital infrastructure alongside its traditional decentralized energy customer base. The company is publicly listed on the Frankfurt Stock Exchange (ticker: 2GNA) and employs more than 1,000 people globally.

Direct peers

• INNIO Jenbacher: One of the largest direct competitors in gas-engine CHP. Jenbacher's gas engines serve the same industrial, utility, and decentralized power markets as 2G's agenitor/avus/aura lines at overlapping kW ranges, with comparable efficiency and fuel-flexibility profiles.
• MWM (Caterpillar Energy Solutions): German gas engine manufacturer (now part of Caterpillar) producing CHP and generator sets directly competing with 2G's product portfolio across biogas, natural gas, and special gas applications in the 20 kW to multi-MW range.
• Rolls-Royce Power Systems (mtu): mtu brand gas engines and CHP systems compete with 2G across industrial, data center, and microgrid applications, offering similar output ranges and gas-fuel flexibility including hydrogen-ready platforms.
• MAN Energy Solutions: Large-scale gas and dual-fuel engines for power generation, CHP, and marine applications. Overlaps with 2G in industrial CHP and biogas-to-power, particularly at the higher end of the kW range.

Broad incumbents

• Wärtsilä: Global provider of engine-based power plants for utilities, industrial, and data center customers. Competes with 2G in larger-scale decentralized gas-fired generation but operates at much higher MW scales and with a broader service portfolio.
• Caterpillar: Diversified power generation incumbent offering gas generator sets and CHP through its MWM and CAT brands. Provides broader balance-sheet and global service capacity that 2G lacks but with similar underlying product technology.
• Cummins: Diversified engine and power generation manufacturer with CHP-capable gas generator sets across commercial and industrial segments. Competes with 2G especially in North American data center backup-power and distributed generation.
• Siemens Energy: Global energy technology incumbent offering gas turbines, distributed generation, and grid services. Overlaps with 2G in industrial and data center power markets but at much larger utility-scale, complementing rather than directly replacing 2G's smaller modular CHP.

Emerging players

• Capstone Green Energy: Microturbine-based distributed generation and CHP provider targeting similar commercial, industrial, and renewable-gas applications. Lower power output than 2G's systems but directly overlapping on behind-the-meter and biogas use cases.
• Viessmann: German heating and energy systems provider expanding into commercial heat pumps and integrated heat-and-power solutions. Comparable to 2G's afilia/NRGTEQ heat pump portfolio and increasingly relevant as a combined heat-and-power bundle competitor.
