Imagine if you could throw green garden waste in here to charge this phone….


– or make energy for a whole city 


We invented just that!

Energy from local woody green waste in Metropole Rouen, France

15. June 2021

The French government and the energy agency ADEME have a clear strategy of using local biomass, which would otherwise just rotten and compost – emitting large amounts of methane gas and CO2.
Dalkia fires up state-of-the-art plant

1. January 2021

Danish biomass gasification and combustion specialists Dall Energy ApS has completed the delivery of a 17 MWth turnkey biomass boiler plant to Rouen, France for the French energy company Dalkia. The heat plant was officially inaugurated on December 10, 2020 with the first fire and handed over on March 5, 2021.
Dall selected for Denmark’s first green waste CHP plant

12. January 2020

In Denmark, Dall Energy has been selected by local heat- ing utility Sorø Fjernvarme A/S to supply a turnkey combined heat and power (CHP) plant to the town of Sorø. (Read more about the construction here)

6 Main benefits of our technology

  1. Low air emissions

Full compliance with latest EU MCP emission requirements without the need for Flue Gas Treatment – reducing investment costs compared to grate-fired solutions.

2 High efficiency

Top-of-market performance with overall efficiency up to 110% and up to 25% reduction in electrical own consumption compared to grate-fired solutions

3 Low maintenance costs

Our patented design has no moving parts that are exposed to the high temperatures in the furnace. There is no grate that needs maintenance. Advanced refractory has minimal wear

4 Fuel flexibility

Various types of low quality biomass may be used even with high moisture content. Locally sourced biomass e.g. garden waste is sustainable, CO2-neutral and also cheaper too

5 Simple operation

The 2-metre-thick layer of fuel in the furnace allows full load operation to continue for many hours if an eventual problem occurs in e.g. a fuel feeding crane

6 High turndown ratio

Steady and controlled operation from full load down to 10% load removes need for district heating plants to invest in separate boiler capacity for low load during summertime

I am deeply impressed, I think it is a really really nice plant we have got here. I am impressed that it is CO2 neutral and that you can use garden waste. I think Dall Energy has delivered something here that has future music in it. ”

Local biomass is sustainable and supports CO2 reductions

Utilising locally sourced biomass for energy production is a sustainable way of decreasing CO2 emissions. Because when biomass is burned it only emits CO2 equivalent to what was absorbed by the plants during their growth. Locally sourced biomass should not be confused with import of wood pellets over long distances, which poses very different benefits and challenges.Our patented biomass gasification furnace accepts low-quality biomass such as garden wastes. This enables more local biomass streams to be of benefit in a local, circular resource stream. Local biomass:

1.    Improves utilisation of local resources

2.    Significant price stability compared to electricity or hydrocarbon-based fuels

3.    Reduces need for transportation

4.    Generates more local jobs
