What Dall Energy does
Dall Energy, founded in 2007 in Hørsholm, Denmark by inventor Jens Dall Bentzen, engineers and delivers biomass energy systems for municipal district heating networks and industrial process heat customers across Denmark, France, and the USA. Its core product is a patented biomass gasification furnace that combines pyrolysis and flue gas condensation to combust moist, low-grade biomass — including local garden and park waste — with reported efficiency up to 110% and emissions compliant with stringent EU standards without the need for separate flue gas scrubbing. The technology platform underpins a portfolio of heating plants, combined heat and power (cogeneration) plants, industrial steam installations, and an Organic Rankine Cycle (ORC) module for electricity generation, supported by recurring operational and maintenance services.
The company's business model combines one-time equipment sales and custom engineering services for multi-megawatt projects (typically 2-50 MW) with recurring operational support contracts, priced on a custom project basis under multi-year agreements. Dall Energy sells primarily through direct enterprise field sales to utilities, municipalities, and industrial operators, supplemented by channel partners in France — a footprint materially expanded by the October 2024 acquisition of French market leader Weiss France Énergie and its service subsidiary BSM. The customer base of roughly 11 named installations includes Danish municipal utilities (Silkeborg Forsyning, Sorø Fjernvarme/AffaldPlus, Sindal, Sønderborg, Bogense), French energy majors and developers (Dalkia, Coriance, Engie Solutions, Amiens Energies), and industrial sites (Clairefontaine paper mill, Warwick Mills in the USA). Growth has been funded by a 10 million EUR growth equity round from Eiffel Essentiel in April 2023 and recognized through the 2011 European Inventor Award and the Financial Times FT1000 ranking (2020).

Dall Energy product offering
Product offeringCore offering
Dall Energy engineers, supplies, and commissions biomass gasification furnace-based heating and cogeneration plants for district heating networks and industrial facilities. Its patented technology combines pyrolysis, gasification, and flue gas condensation to convert moist biomass — including low-grade fuels such as garden and park waste — into thermal energy (and optionally electricity) at efficiencies up to 110% with very low emissions, eliminating the need for separate low-load boilers or flue gas scrubbing.
Product overview
Dall Energy offers a portfolio of biomass energy products centered around its patented biomass gasification furnace technology. The core product line includes Heating Plants for district heating networks and Cogeneration Plants for combined heat and power production, complemented by Industrial Applications for manufacturing processes. Supporting the core products are Operational Support services and ORC Agent modules for organic Rankine cycle power generation. The technology platform is built on key components including Pyrolysis Technology and Flue Gas Condensation, all working together to deliver high fuel flexibility, efficiency up to 110%, and very low emissions without requiring flue gas scrubbing equipment.

Products and services
- Heating Plants (Varmeværker) District heating plants delivering sustainable heat to community district heating networks with very low local air emissions. Stable and controlled operation from 100% down to 10% load without requiring a separate summer boiler. Targeted at municipal and publicly owned district heating utilities.
- Cogeneration Plants (Kraftvarmeværker) Combined heat and power (CHP) plants that simultaneously produce heat and electricity from biomass using Dall Energy's gasification furnace, optionally paired with an ORC generator (ORC Agent). Designed for district heating operators and industrial sites needing both thermal energy and power.
- Industrial Applications (Energi til industrien) Customized biomass energy systems for industrial processes, including steam production for manufacturing facilities such as paper mills and textile plants. Targeted at industrial energy consumers seeking to replace fossil fuels with biomass.
- Operational Support (Driftssupport) Ongoing operational support and maintenance services for installed Dall Energy biomass systems, ensuring optimal performance, uptime, and minimal maintenance burden for customers.

Broad incumbents
- Valmet: Finnish global leader in pulp, paper, and bioenergy solutions with a large biomass boiler and CHP plant business. Significantly larger scale and broader portfolio than Dall Energy but addresses the same district heating and industrial biomass heat customers.
- ANDRITZ: Austrian industrial group with a major biomass boiler, CHP, and bioenergy plant business serving utilities and pulp/paper customers globally. A much larger established incumbent in the same end markets as Dall Energy.
- Metso: Finnish industrial company providing biomass-fired energy solutions, including boiler islands and CHP plants for district heating. Large, diversified incumbent competing in the same biomass heat-generation end markets as Dall Energy.
- Babcock & Wilcox (B&W) Volund: Global boiler and environmental technology group whose Volund line historically serves the European biomass and waste-to-energy district heating market. Established incumbent competing for the same utility and industrial customers as Dall Energy.
- Fortum: Nordic energy major with district heating operations across the Nordics, Baltics, and Poland, including biomass-fired CHP plants. Functions as both a potential customer (heat offtaker) and a much larger competitor with in-house biomass capabilities.
Others
- AIT STEIN: Austrian boiler manufacturer that holds a technology licensing arrangement with Dall Energy to produce boilers incorporating Dall's patented gasification technology. Closely linked but functions as a manufacturing partner rather than direct competitor.
