Wood is at the forefront of the global shift to a renewable, more sustainable energy economy. Its efficient production and utilization and the supply of heating customers reliably via local heating networks were high on the agenda on 31 May at the Heating with Wood conference. The event was organized jointly by agricultural publisher Deutscher Landwirtschafts Verlag (dlv) and the Lower Saxony Agricultural Association.
For forest owners, whose customers come from a range of markets, including the wood processing and sawmilling industries and, increasingly, the wood energy sector, the key is to have the right silviculture strategies in place so that they can provide the required timber varieties.
Günter Schröder, head of forestry at Hannover’s municipal energy company enercity, explained the silvicultural options available for servicing today’s energy wood markets. On the technology front, Carsten Brüggeman of the Lower Saxony Agricultural Association (LWK Niedersachsen) outlined the current state of the art in wood fuel utilization and presented the latest innovations at LIGNA.
With demand for wood energy on the rise, forest timber species suitable for energy use are likely to become depleted unless more use is made of short-rotation coppicing on farmland. Against this background, Christian Ihl and Michael Kralemann of the Lower Saxony Renewable Raw Materials Network (3N) outlined the profitability requirements for poplar and willow cultivation in short-rotation coppices and explained how thermal energy produced from wood can be marketed via local heating networks.
