Geothermal Europe: Erding

In series of articles “Geothermal Europe”, case by case we would like to introduce the ways, how geothermal energy is being used in Europe. The first project is geothermal solution in German city Erding. There are two main projects: aquapark Therme Erding and the energy solution for Erding city. THERME ERDING The biggest geothermal aquapark… » read more

We browsed Internet and tried to find as simple as possible and the most illustrative video explaining the principles of geothermal energy. After hours of searching, we would like to recommend one created by UCTV. Right below your feet is a source of renewable energy that is largely untapped. It heats groundwater by conduction and… » read more

Kalina Cycle

The next one among geothermal cycles is called “Kalina Cycle”. It has been given name by its inventor, Russian engineer Alexander Kalina. Beside Organic Rankine Cycle (ORC), Kalina Cycle is another cycle used in power facilities fueled by geothermal water streams of lower temperature. In comparison with Organic Rankine Cycle, the main advantage of Kalina… » read more

Like we mentioned that the principle of geothermal power plant lies in thermodynamic cycles, we would like to write briefly about one of them, so called Organic Rankine Cycle (ORC). Firstly, what is a Rankine Cycle? In general, it is a thermodynamic cycle used in turbines in order to produce electricity. It is one of… » read more

How geothermal heat is transformed in order to be used in turbines producing electricity? Thanks to “thermodynamic cycles”. They are the set of various thermodynamic processes, which are based on the “law of conservation of energy”. It tells us that energy is isolated system and its amount remains constant; energy cannot be created or destroyed,… » read more

Imagine the geothermal power plant. As long as you look at it, you will see some type of „smoke“ rising up from strange wide „chimney“. Is this real smoke? Is that real chimney? No. Right answer is that just the water steam is rising up from the cooling tower, not from chimney. Therefore the question… » read more

Strong and weak aspects one can identify when studying various issues. Let’s summarize impacts of geothermal energy. In this shot we will write about impact on environment, the next one will be focused on human health impact. The linguistic origin says that „Geothermal“ represents the heat coming from Earth’s depths („Geo“ like Earth, „thermal“ like… » read more

All of you know that: Imagine you are on the beach during a sunny summer day. No clouds, no wind, just sun. Suddenly you decide to walk without shoes on your feet. Possible? Impossible because rocky road is too hot for your skin on feet. Actually, the rock can be good absorbent of enormous heat… » read more
