What ServiceUnion does

ServiceUnion GmbH is a privately held industrial services company specializing in the maintenance, optimization, and modernization of biogas plants and combined heat and power (CHP) units. Founded around 2012 and headquartered in Bannberscheid, Germany, the company operates as the service arm of the bestore Group alongside parent agriKomp GmbH (a biogas plant OEM) and Formprotect GmbH. Its service portfolio spans plant service, CHP service, electrical service, laboratory service, planning/plant design, and repowering — delivered through a direct field-sales model with 8+ regional service locations in Germany and proximity agencies across France via its subsidiary ServiceUnion France SAS.

The company's product layer is built on several proprietary technologies developed in cooperation with SCANIA and agriKomp: the DC13 ETA and OC09 ETA engine conversion kits that upgrade legacy SCANIA DC12, Doosan V8, and agriKomp BGA136/BGA158 engines to modern Gas-Otto technology at up to 43% efficiency; modular Selective Catalytic Reduction (SCR) systems that bring CHP emissions to 0.1 g/m³ NOx per 44th BImSchV; the FormProtect modular PVC container system for acid-resistant, gas-tight digester construction; and a branded consumables line (Enzymaxx enzyme blends, Fermaxx trace elements, ak POWER 1000 gas engine oil, iron hydroxide, activated carbon, and Biolene EPDM gas storage membranes). Over 70 SCR systems have been installed and commissioned since 2022.

The business model combines recurring maintenance and telemaintenance contracts (subscription-style) with hardware sales (spare parts, consumables, SCR systems, engine conversion kits) and project-based professional services (planning, repowering, regulatory approvals under EEG, 44th BImSchV, TRAS 120, and Redispatch 2.0). Customers — primarily agricultural and industrial biogas plant operators in Germany and France — reach the company via a free technical hotline, regional offices, the akCockpit monitoring portal, or on-site dispatch. The company does not publicly disclose pricing, instead providing quotes on request, and assists customers with BAFA and KfW subsidy applications for energy efficiency upgrades.
