http://www.alenko-ag.ch/images/geothermie3.jpgHot water is extracted from a borehole at a depth of 3,000 meters and channeled into a steam turbine to generate electricity. The turbine circuit is powered by an organic tool known as the Organic Rankine Cycle (ORC) to allow heat recovery even from low temperature sources. ORC uses a high molecular mass organic fluid. Ideally, surplus heat can also be used to heat and cool living and office space. Geothermal power systems can be operated for about 8,300 hours per year regardless of the weather conditions; thus, in contrast to wind or solar power, the payback period is relatively short and can be accurately calculated.

ALENKO plans and examines such technical processes and is regularly brought in as a consultant for investors due to its profound knowledge in this area.
