Green Energy from the Green Valley


30.04.08

In biomass technology Styrian companies cut the edge. The intensive research at the Austrian Bioenergy Center, KWB’s countless biomass heating innovations and the Steirische Gas-Wärme GmbH’s biomass combined heat and power plant are proof of the leadership of this well-known „Green Valley“.


Through the issue of international environmental protection laws biomass has experienced another upturn. Styrian companies have been involved in the production of green energy for several decades. Distinctions such as the presentation of the Nobel Peace Prize to the Intergovernmental Panel on Climate Change (IPCC), in which Styrian biomass researchers play a large role, demonstrate Styrian leadership in this area on a continual basis.


The energetic utilisation of solid biomass is the business of the Graz-based competence centre Austrian Bioenergy Center GmbH (www.abc-energy.at), referred to as ABC for short. It is not only a matter of biomass itself, but also its upgrade, the conversion processes, ecological links and economic considerations.


In its five years of existence, along with its external office in Wieselburg ABC has consolidated its position as a global scientific player and contributed significantly to the realisation of reasonable approaches to energy policy such as value creation from biomass, training programs for boiler manufacturers and the development of new pellets, for example out of reeds. With 72 partners in business, internationally recognised scientists and excellent human resources, the competence centre intends to play a meaningful role in “sustainable energy supply” in the future as well.


“We provide energy for life” is the principle of KWB – Kraft und Wärme aus Biomasse (www.kwb.at). With a research quota of 20 percent, it has the biggest biomass research unit, which produces innovative technology on a steady basis.

The latest achievement is the so-called “pellet-fired agitator plus,”a new kind of pellet production system which saves on space, assembly time and costs. “For us heating does not stop at just heating, we also want to provide innovative services for the new biomass heating systems,” KWB Managing Director Erwin Stubenschrott says, describing the development of a new kind of financing system: now KWB biomass heating systems can also be leased. This is interesting, particularly for commercial customers; after all, eco-heating saves the money that covers the leasing rates.

KWB founders Dr. August Raggam and Erwin Stubenschrott were among the pioneers in biomass technology in Austria and at the beginning were laughed at for their vision of fighting climate change through the use of renewable energies. Today, more than 30 years later, KWB is market leader for biomass heating.

 

Steirische Gas-Wärme GmbH (www.e-steiermark.com) was created in 2003 out of the district heating firms Steirische Fernwärme GmbH and Steirische Ferngas Gesellschaft mbH and since then has actively invested in promising and environmentally compatible energy projects in all of Austria, Slovenia, Croatia and Slovakia.

One of them is BKL, the biomass combined heating facility in Leoben located at the Mayr-Melnhof lumberyard. The world’s biggest plant based on organic rankine cycle processes – a process of operating steam turbines with something other than steam – produces total output of 4.5MW using lumber byproducts accumulated direct at Mayr-Melnhof Holz GmbH as fuel. 60 percent of the resulting ash is used in the production of cement.

“It was important for us to find a technically, economically and ecologically optimal solution enabling the efficient production of thermal heat and ecopower” states Günter Dörflinger, speaker of the management board of Steirische Gas-Wärme GmbH. This occurs primarily through the use of modern flue gas purification plants and the general avoidance of truck and wheel-loaders for the facility’s fuel supply, which reduces the air pollution in the Leoben basin considerably.


Decades of know-how and a high rate of innovation in energy production from renewable raw materials ensure Styrian companies’ leadership and open up new chances on the market in the area of biomass technology.
