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!


Dall Energy's vision is to provide new biomass energy technologies to the global market

We offer low maintenance solutions for district heating networks and the industry


And we reduce environmental impact from energy production by improving air emissions and using locally sourced biomass which is cheap, sustainable and CO2 neutral

Main benefits of our technology

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

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

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

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 cheaper too

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

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 believe we got a really nice plant here. I am impressed that it is CO2 neutral and it utilises garden waste wood. What Dall Energy has provided here comprises the music of the future.”

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. Poses significant price-stability compared to electricity or hydrocarbon-based fuels
  3. Reduces need for transportation
  4. Generates more local jobs
