Revenue model

1. Geothermal Heat Sales (District Heating): Naturwärme sells geothermal heat to municipalities, commercial businesses, and industrial customers via direct district heating connection agreements. Heat is delivered through pipeline infrastructure from the Halsbach geothermal source. The pricing is long-term contract based, not publicly disclosed, and is negotiated with each municipal or commercial customer. The heat source is sold as a utility service — price-stable and independent of fossil fuel markets or CO2 pricing.

Core offering

Naturwärme Kirchweidach-Halsbach operates a deep hydrothermal geothermal heat source in the Bavarian Molasse Basin, extracting thermal water at temperatures above 107°C from a borehole reaching approximately 3,050 meters vertical depth (4,900m total measured depth). The company sells CO2-free geothermal heat via district heating pipelines to municipalities, commercial enterprises, industrial operations, and a 30-hectare greenhouse complex, operating under a closed-loop doublet system with buffer storage for supply reliability.

Product overview

Naturwärme Kirchweidach-Halsbach is a joint venture between Gemüsebau Steiner and the municipality of Kirchweidach operating a deep geothermal heating system in the Molasse Basin of Bavaria. The company's core product is geothermal heat energy extracted from a successful 3,050-meter-deep borehole at the Waldweihnacht site in Halsbach, delivering water temperatures exceeding 107°C. This heat is distributed through district heating pipelines to multiple end-users: the Steiner family's 30-hectare greenhouse complex in Kirchweidach (making them the first vegetable-growing company in Germany with its own geothermal source), the municipal heating network of Kirchweidach, and future connections to the city of Burghausen via an 8+ km pipeline. A large buffer storage facility near the bore site ensures supply reliability. The company does not operate a software product; its offerings are physical energy infrastructure and heat supply services.

Partnerships

Four partnerships are on record, tiered core.

• Energieversorgung Burghausen (EBG)coreChannel Partner/ Reseller/ Distributor · 1 March 2025EBG is the municipal energy utility of the city of Burghausen and a subsidiary of the city government. EBG signed the heat supply contract with Naturwärme Kirchweidach-Halsbach in March 2025 and will operate the integration of Burghausen's existing and planned district heating network with the geothermal heat source. EBG functions as the distribution channel partner responsible for delivering geothermal heat to end consumers in Burghausen.
• Stadt BurghausencoreStrategic or Co-development Partner · 1 March 2025The city of Burghausen (population approximately 20,000) entered into a Letter of Intent (LOI) and subsequently a heat supply contract with Naturwärme Kirchweidach-Halsbach in March 2025. Burghausen will receive CO2-free geothermal district heating via a new pipeline from Halsbach, with supply expected to begin in the 2027/28 heating season. This is a flagship municipal partnership in Bavaria's energy transition.
• H. Anger's Söhne Bohr- und Brunnenbau GmbHcoreStrategic or Co-development Partner · 1 September 2022H. Anger's Söhne from Hessisch Lichtenau was selected as the drilling contractor for the geothermal well at the Waldweihnacht site in Halsbach. The company is described as a highly experienced and qualified deep drilling and well construction firm, which also successfully carried out the earlier geothermal drilling at Kirchweidach. They operated the Innova-Rig 418 drilling rig at the site, working 6 days per week in two 12-hour shifts.
• Gemeinde KirchweidachcoreStrategic or Co-development PartnerGemeinde Kirchweidach is the co-founding partner of the joint venture Naturwärme Kirchweidach-Halsbach GmbH & Co. KG, alongside Gemüsebau Steiner. Kirchweidach's mayor, Robert Moser, serves as co-managing director (Geschäftsführer) of the joint venture. Kirchweidach receives geothermal district heating for its municipal network and represents the municipality as both customer and co-owner of the geothermal project.

Direct peers

• Geothermie Unterhaching GmbH: Pioneering Bavarian deep geothermal project supplying heat (and electricity) to the municipality of Unterhaching near Munich from the Molasse Basin. Operates a hydrothermal doublet at similar depths and serves as the closest structural and geographic analogue to Naturwärme's Halsbach project.
• Geothermie Holzkirchen GmbH: Deep geothermal heating project in Holzkirchen, southern Bavaria, targeting the same Molasse Basin Malm carbonate aquifer. Directly comparable in technology (hydrothermal doublet), customer profile (municipal district heating), and regulatory framework.
• Erdwärme Grünwald GmbH: Deep geothermal district heating supplier to the municipality of Grünwald near Munich from the Molasse Basin. Closely comparable in scale, technology, and customer mix to Naturwärme's Halsbach-to-Kirchweidach configuration.
• Geothermie Riem GmbH: Munich-based deep geothermal project supplying heat to the Messestadt Riem district from the Molasse Basin. Comparable in reservoir, doublet configuration, and municipal district heating off-take model.
• Geothermie Taufkirchen GmbH: Deep geothermal heating project in Taufkirchen (southern Munich suburb) producing hot water from the Molasse Basin for district heating — a near-twin of Naturwärme's hydrothermal architecture and customer base.

Broad incumbents

• Stadtwerke München (SWM) – Geothermie: Munich's municipal utility operates multiple deep geothermal projects (Riem, Freiham, Sauerlach) supplying heat and power across the city. Broader incumbent in the same Bavarian geothermal district heating space, with portfolio scale well beyond Naturwärme's single-asset configuration.

Emerging players

• Aardwarmte Vogelaer B.V. Dutch deep geothermal doublet supplying heat to greenhouse operations (Westland area). Comparable in the specific use case of geothermal heat for industrial greenhouse horticulture, the same end-application as Naturwärme's Steiner greenhouses anchor.
• Trias Westland B.V. Cooperative of Westland greenhouse operators developing a shared deep geothermal doublet for horticultural heat supply. Relevant analogue for the JV model combining agricultural heat off-takers with a shared geothermal asset.
