What Spanner Re² does
Spanner Re² GmbH is a German manufacturer of decentralized biomass gasification combined heat and power (CHP) systems and pellet heating equipment, headquartered in Neufahrn in Lower Bavaria. Founded in 2004 and operating with 51-100 employees, the company designs and builds modular Holz-Kraft-Anlagen (HKA 35 through HKA 700, scalable into multi-MW configurations) that convert wood chips, pellets, waste wood, agricultural residues (including macadamia shells and kernels), and industrial byproducts into synthesis gas via proprietary pyrolysis-based wood gasification; the syngas is then used in integrated CHP units for simultaneous electricity and heat, or directly burned in industrial thermal processes as a natural-gas substitute at temperatures above 1,000°C. The company complements this industrial line with Re² Pelletheizungen (4-100 kW thermal) developed from the 2016 HAPERO brand acquisition, and a webshop for spare parts, retrofits, and refurbished systems priced roughly 30% below new units.
The commercial model is primarily direct enterprise sales of high-value, quote-based hardware (40/60 payment terms) targeting sawmills, agriculture (farms, dairies, cooperatives), municipalities, hotels and wellness facilities, logistics operations, and energy-intensive industrial buyers including brick, metal, and food processors. Distribution combines a field sales team with relationship-driven demand generation through 'Energietage' (Energy Days) on-site demonstrations, IFAT trade fair participation, and a content/news footprint across the website, YouTube, and social channels; recurring revenue is supported by spare-parts supply, power-class engine upgrades using AGCO-Power systems, energy delivery contracting, and a refurbishment trade-in program. With 1,000-1,100+ plants operating globally across Germany, Austria, Switzerland, Slovenia, the Netherlands, Poland, the UK, Congo, Japan, and New Zealand, recent strategic priorities have shifted toward industrial process-heat decarbonization and multi-MW projects, exemplified by 2025-2026 partnerships with 2G Energy AG and Charwood Energy Group and a March 2025 product launch of the HKA Pellet gasifier.
