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.


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.

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.

Current discussions surrounding the routing of power lines, large-scale power plants, nuclear and coal power as well as prices for heating and electricity show: decentralized power and heat generation is the way of the future. The energy of the sun and biomass are the most important resources. Thomas Bleul, Managing Partner at spanner, explains the role of wood in this ongoing change.

Wood – the energy source of the future

We believe that biomass plays a very important role in the energy supply of the future. Woodchips are a simple, readily available fuel class and available in a decentralized fashion at most locations and in sufficient quantities. This resource can therefore contribute to reaching the goals of the energy transition in a valuable manner, as it is capable of covering the primary energetic needs several times over: (cf.
