What Keep It Green Gmbh does

Keep It Green GmbH is a privately held German engineering, project management, and consulting firm headquartered in Starnberg, Bavaria, founded in 2000 and operating additional offices in Fürstenwalde (Berlin/Brandenburg) and Leipzig. The firm serves the energy industry — specifically gas network operators (e.g., Bayernets, Open Grid Europe, Ontras, NBB), municipal utilities / Stadtwerke (e.g., Stadtwerke Heidelberg, Stadtwerke München, Mainova), and industrial energy consumers (e.g., Daimler, BMW, Papierfabrik Palm). Service delivery is organized into three pillars: Engineering (gas technology, electrical and control systems, heat/CHP plants, industrial media supply, civil engineering), Project Management (end-to-end leadership from consulting to full responsibility), and Consulting (asset management, feasibility studies, regulatory and certification support for network operators and utilities). The company is DVGW G 493-1 Group 3 certified (since August 2014) for planning gas pressure regulation and metering stations up to 100 bar and holds active roles in DVGW, GPM, Figawa, and Bayerische Ingenieurkammer-Bau.

The firm monetizes its services as a B2B professional services consultancy on a project-based, quote-based revenue model with no disclosed pricing or subscription terms. Sales motion is relationship-driven, consultative enterprise field sales — typical for long-cycle German energy infrastructure projects where trust, regulatory credentials, and 20+ years of track record are decisive. Notable customer evidence includes a multi-year gas technology and electrical planning contract with NBB Netzgesellschaft Berlin-Brandenburg from 2015, a biogas upgrading plant at Mainova Frankfurt achieving ≥98% availability and roughly 3 million Nm³ of annual biomethane production, and a biogas injection plant for Papierfabrik Palm with peak capacity of 1,410 Nm³/h. The customer base spans approximately 40+ named enterprise logos.

Technology differentiation rests on single-source multi-disciplinary engineering (gas, electrical, thermal, civil), early-mover hydrogen expertise dating to the early 2000s (with documented compression work up to 350+ bar), DVGW regulatory credentials, and deep embedding in German government-funded hydrogen research consortia (TransHyDE, TrafoHyVe, H2Giga, Westküste 100, MethQuest, BGA-Cluster). In 2023 the firm secured a process engineering development contract from Rolls-Royce Solutions GmbH for next-generation electrolyzer components, marking entry into hydrogen production equipment design. Headcount is in the 11–50 band, ownership is founder/management-held with no disclosed external investors, and the legal form is a German GmbH.
