Find out everything about wood gasification in our blog.
In this blog you will also get the latest information about our company Spanner Re² GmbH.


On 4 days in September the National ploughing championships are happening. One of Europe's largest agricultural show expects 300.000 visitors. Spanner RE² is exhibiting their wood chips driven Biomass CHP there the first time.

Peter Oberbacher is self sufficient with electricity and heat by wood gasifier

The Oberbacher family’s Inn River Valley four-sided farmyard is located in the Bavarian Alpine foreland, bordering to the northern Chiemgau area. Existing for more than 500 years, the agricultural enterprise at the time of his great grandparents still actively utilized an ox-driven capstan. At that time the energy so generated by the movement of animals was used to drive various agricultural facilities. Thereby a transmission line shaft brought the mechanical power to the respective places of consumption.

The Fraunhofer Institute for Environmental, Safety and Energy Technology, UMSICHT, Institute Division Sulzbach-Rosenberg, is currently testing cyclone firing systems with digested residues. That concerns a specific firing technology, which is particularly suitable for biogenic residues and is applied where standard firing systems would fail.

On Saturday, July 2, Spanner Re² GmbH celebrated the 10th anniversary of the company and the delivery of the 500th wood cogeneration plant with an in-house trade fair and a festive evening for all plant operators and employees and friends of the company.

16-06-21: We are now reverting to an earlier CHP gasifier design! Please see the picture.

Farmer installed Biomass CHP

A farmer, JS Baird runs a farm of mixed arable, livestock, broiler chickens and laying hens in Scotland. His aim was to reduce his electricity and heat demand and he wants to go green. His idea was to run a CHP with wood chips, a so called Biomass CHP.

Spanner Re² GmbH participated in the RENEXPO in Belgrade. Especially the Western Balkans have a high potential for renewable energies. RENEXPO is one of the hot spots for energy experts.

Why Spanner Re² wood cogeneration plants

When JS Baird and Sons, Scotston Farm, Angus (customer of Spanner Re² since 2014) were investigating further improvements to their renewable portfolio, they happened across an emerging technology, Gasification. Wood gas has been used for many years in small scale installations as a substitute for petrol. The great advantage of the technology is that instead of burning woodchips in a biomass burner, the gasifier converts the wood chip into ‘syngas’ which is then used to drive a CHP.
