Through eta Energieberatung a sustainable concept for a secure procurement of fuel assortments was developed and a regional market overview was created. In addition, a profitability analysis and a sustainability assessment was carried out.
In Taufkirchen (Vils), a district heating network with a route length of approx. 5,200 m and 41 heat transfer stations was built. The base load requirement is covered all year round by combined heat and power plants. In addition, a community-owned conventional peak and reserve system was also set up.
In Engelsberg, a biomass heating plant with a capacity of 1,700 kW and a district heating network with a route length of approx. 7,400 m and 180 heat transfer stations were built. Afterwards, the biomass heating plant and the district heating network were optimised during operation.
At Lauterbach castle, which has been owned by the von Hundt family since the 15th century, the oil heating system was replaced by a woodchip heating system. A neighbouring house is also supplied with heat by this system. eta Energieberatung was commissioned with the planning of the wood chip heating with connected local heating network.
The community Wunsiedel will become a pellet stronghold through the investment of 30 million euros in the new pellet plant with a connected CHP. The new pellet plant is supplied with the necessary energy by three connected natural gas CHPs.
It was analyzed how the location can be supplied with energy in a CO2-neutral manner. For efficient energy generation and optimal use of fuel with biogas cogeneration units, the heat supply had to be split into a separate high and low temperature supply.
After successful cooperation with the wood pellet plant, the Stadtwerke Wunsiedel also relied on the technical support of eta Energieberatung for this local heating concept with a wood gas cogeneration unit and pellet boilers.
Daimler AG is building a new engine plant in Jawor (Poland). The energy supply should be CO2 neutral via external suppliers. Eta Energieberatung was involved in the concept creation and implementation for the CO2-neutral heat supply as well as a transitional supply to the engine plant.
As part of a feasibility study for the implementation of a JI project in Bulgaria, a baseline study, a monitoring plan as well as a sink and emission reduction study were carried out. The subject of the project was the conversion of the heating supply to biomass. Biomass pilot projects were initiated in two selected municipalities.
On behalf of the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, a pre-feasibility study was carried out for the conversion of an industrial production site from heavy oil to biomass and the increase in energy efficiency through combined heat and power.
The core of the pilot project is the drying of sewage sludge directly on a sewage treatment plant using low-temperature waste heat from a wood-fired biomass cogeneration plant. The dried sewage sludge is easy to transport and is a welcome and CO2-neutral fuel substitute with high calorific value for the recyclers.
