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.


Rwenzori e.V. works as a non-profit association with the aim of funding and implementing agricultural development projects in Uganda.

In close co-operation with our partners in Uganda, Rwenzori is building a secondary school, reforesting the Rwenzori mountains and, since last year, its newest project has been to establish an agricultural school. Further projects are in the planning stages.

Spanner Re² wins the 2016 ZLF Innovation Prize

The most compact wood cogeneration plant of its kind – the “HKA 10” – now also generates environmentally friendly heat and electricity with pellets. Spanner Re² was recently awarded the coveted ZLF Innovation Prize for 2016 by the Bavarian Farmers’ Association and the “Bayerisches Landwirtschaftliches Wochenblatt” for this future-oriented wood cogeneration plant.

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.

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.
