International Geothermal Conference GEOHEAT
Date and Location
The 2nd International Geothermal Conference GEOHEAT 2018 will be held on 04 – 07 September, 2018 in Petropavlovsk-Kamchatsky, Russian Federation. This year, the Institute of Volcanology and Seismology, Far Eastern Branch will host the event.
There are five main renewable sources of energy:
- Biomass. The term is commonly used to identify energy derived from plants. Unfortunately, this type of energy is hardly sustainable, due to the fact that it widely includes burning trees for cooking and warmth.
- Solar energy
- Wind energy
- Geothermal energy
So what is geothermal energy? Our planet continuously generates and stores thermal energy, due to its very hot core. Another reason for this thermal energy generation is radioactive decay of materials. The temperature difference between the Earth’s core and its surface is very different (over 4000 degrees Celsius at the core mantle). Therefore, a continuous conduction of thermal energy from the planet’s core to the surface, exists. People have used geothermal energy already from Paleolithic times, when the water from hot springs served for bathing purposes. Nowadays this energy serves much more advanced purposes. People use it to heat their homes and, more importantly to produce electricity. The latter can be done by drilling deep wells and pumping the hot underground water to the surface.
It is important to mention that such wells release greenhouse gases into the atmosphere. However, by a unit of produced energy the effect of these greenhouse gases is considerably smaller than a similar negative influence of a conventional (fossil) fuels. Thus, geothermal energy is a reliable, sustainable and environmentally-friendly energy source.
Already in the 14th century the first geothermal-powered district heating system was operating in Chaudes-Aigues (France). More information about this extraordinary development can be found here. In 1827 the earliest industrial exploration of the Earth’s inner energy began in Larderello, Italy. Currently, there exists an ever-growing demand for geothermal energy, thanks to its numerous benefits.
Geothermal power is, obviously, power, generated by geothermal energy. Nowadays, 24 countries make use of geothermal electricity generation, while geothermal heating is in use in not less than seventy countries. Geothermal electric stations are generally located at places where high temperature thermal resources are available near the surface – usually by tectonic plates junctions. The principle of work of a geothermal power station is as follows: first, heat from the Earth’s core heats working fluid (usually water) of a power station. This working fluid consequently causes a turbine of a generator to rotate, which in turns produces electricity.
The main drawback of this type of power is its cost-inefficiency. Exploration of new areas and especially drilling is very expensive. Despite the fact that people nowadays are more and more ready to pay additional fees for sustainable and renewable energy supplies, geothermal energy is still far less popular than solar or wind power.
According to the Second Announcement of the conference: “The goals of the conference are:
- distribute scientific and industrial information concerning current state of geothermal science, technology and industry.
- share knowledge and results in theory, methodology, technology and applications of geothermal science.
- bring together scientists, researchers, engineers, students and managers interested in geothermal science.
- promote geothermal innovations.
- provide a forum to exchange ideas on the exploration, development and use of geothermal resources.
- encourage international communication and collaboration.
