CO2 Neutral, Low Emission Small Scale Biomass CHP Plants Based on Updraft Gasification and Stirling Engines - Technology Development

G. Marinitsch, J. Bovin, T. Gørtz, K. Mygind & H. Carlsen
The biomass CHP technology based on updraft gasification and Stirling engines enables the production of high value electricity and heat in an efficient way in applications below 300­500 kWe electric power output. Thus, a technology gap for the electricity production is filled for carbon neutral small scale CHP plants. The technology is currently entering the market with the first commercial installations in Denmark, Germany and the UK. In this paper, a detailed evaluation on the...
