Renewable energy from biomass

Biomass can in an dense inhabited industry country be only a complement to electric power from sun and wind. At all enthusiasm for biomass, do not neglect the photovoltaic.






Fertilizer collection Fertilizer collection
Here the farmers with the liquid manure barrels behind the tractor take over the liquid manure. The material what comes from the fermentation gas system is similar to cow dung.


Fertilizer from the fermentation gas equipment Fertilizer from the fermentation gas equipment
The lagoon catches 2,000 cubic meters fertilizers. After 6 months of fermentation gas production the lagoon is full. Then there come the farmers and fetch the valuable fertilizer.

From the left to the right: District heating Strem with 2 * 500 kWh of gas engines. The gas tent of the second fermenter, the driving silo. The rest can not be seen from here.


Biogas direcly from plants Biogas direcly from plants
More hectare yield in energy allows the biogas production in Strem. Using again fallow sites for the agriculture, an income for farmers from the energy production.


Electric power and warmth from biomass
The design of the equipment will strongly change during the next 20 years. At the moment such equipment are construed as constantly running run power stations.




Second fermenter 1500 m³ Second fermenter 1500 m³
The tent roof serves as a gas storage. The storage can store the produced gas for 11.5 hours. At the moment electricity and heat is produced with the gas in a 500 kW gas engine.


Main fermenter 1500 m³ Main fermenter 1500 m³
For the start, 1300 ms ³ sanies had been introduced to the bacterial cultivation . Another research equipment got by 2 years without slury supplies, here the researchers hope more.


Solid entry Solid entry
From the driving silos are up to 50 cubic meters of biomass all at once brought in the solid entry. This thing is comparable, so to speak, to the mouth of the cow.


Driving silo as a biomass depot Driving silo as a biomass depot
10,000 metric tons of biomass of the maize cultivation are delivered here per year in the driving silos. Each of 4 driving silos is 15 ms wide and 70 ms long.

What hangs here as an facility scheme of the Thöni biogas production on a wall, we introduce on the next sides photo for photo in the reality.






  Energy supply with renewable energy


Huge changeovers in our energy supply are imminent. We report over the condition of the technologies and their future-potential of different sources of energy.

Photovoltaic - Electric power direct from light Photovoltaic - Electric power direct from light
Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential.


Thin layer photovoltaic Thin layer photovoltaic
Less material and less energy usage at the production, good outcome at cloudy sky and the possibility for flexible PVs are the advantages of thin film technology.


Photovoltaic roof integration Photovoltaic roof integration
Reduce costs by photovoltaic roof integration instead of making the roof and all the photovoltaic seperat with much more work time.


Photovoltaic and heat combined Photovoltaic and heat combined
Cogeneration of electric power and heat from one modul. Optimal utilization of roofs by combined production of electric power and heat on the same area.


Photovoltaic Inverter
Inverters for the grid connection of photovoltaic systems. Directory over all our reports about inverters.


Photovoltaic off grid systems Photovoltaic off grid systems
Off grid photovoltaic systems. Directory over all our reports about off grid PV systems.


Solar thermic Solar thermic
Producing heat by solar energy. Directory over all our reports about thermic solar energy usage.


Wind energy - wind power plants Wind energy - wind power plants
Wind power plants. Directory over all our reports about wind energy.


Energy from wood Energy from wood
Where is energy from wood usefull in a long term? Where is the use of wood for energy maybe only a short time fashion hype without sustainability?
