Living without gas through torrefied biomass

Living without gas through torrefied biomass

The Dutch news has been dominated in recent weeks by reports of earthquakes in Groningen, the reduction of gas production, and what this will mean in reality.

A heat pump can easily be installed in new houses and new-build complexes. Moreover, new-build houses are so well insulated that the residents certainly want to have cooling in rooms facing south. A heat pump can provide both heating and cooling in these houses. The biggest challenge is in existing houses. These houses are not equipped for the low-temperature heating system of a heat pump. In addition, these houses have a higher heat demand.

Gasloos wonen biomassa torrefactieCCS Energie-advies believes in heat grids based on biomass boilers (including wood). However, there are many more biomass residual streams released which currently can’t be used for energy generation.

CCS Energie-advies has entered into a partnership with Klinkenberg, builder of the installation and BioLake, who provides a demo installation for torrefaction. Together we work  on solutions to use these residual streams for energy generation. By torrefying these residual streams, a kind of roasting, fuel pellets can be made. As a result, these residual streams are more uniform in terms of combustion properties and can be better inserted into the boiler.

CCS Energie-advies has supported Klinkenberg and BioLake for several years in drawing up the process design, the mass and energy balance and the business case of torrefaction. By means of an MIT subsidy from the province of Noord-Holland, further research is being done into the torrefaction properties and the control of the torrefaction process in order to make a consistent quality of fuel pellet in an energy-efficient manner.
