A life cycle analysis was performed for the assessment of the environmental performances of three existing Italian power plants of comparable nominal power operating with different sources of renewable energy: Geothermal, solar, and wind. Primary data were used for building the life cycle inventories. The results are characterized by employing a wide portfolio of environmental indicators employing the ReCiPe 2016 and the ILCD 2011 Midpoint+ methods; normalization and weighting are also applied using the ReCiPe 2016 method at the endpoint level. The midpoint results demonstrate a good eco-profile of the geothermal power plant compared to other renewable energy systems and a definite step forward over the performance of the national energy mix. The Eco-Point single score calculation showed that wind energy is the best technology with a value of 0.0012 Eco-points/kWh, a result in line with previously documented life cycle analysis studies. Nevertheless, the geothermal power plant achieved a value of 0.0177 Eco-points/kWh which is close to that calculated for the photovoltaic plant (0.0087 Eco-points/kWh) and much lower than the national energy mix one (0.1240 Eco-points/kWh). Also, a scenario analysis allowed for a critical discussion about potential improvements to the environmental performance of the geothermal power plant.

The Impact

Összefoglaló. A dolgozat témája a különböző erőműfajták életciklusra vonatkozó fajlagos anyagigényének a vizsgálata. Az elemzések a nemzetközi szakirodalmi források felhasználásával történtek. Módszere, a bázisadatok elemzése, majd az anyagigényeknek az erőmű beépített teljesítményére és az életciklus alatt megtermelt villamosenergiára vonatkoztatott fajlagos értékek meghatározása. Az eredmények azt mutatják, hogy a nap- és szélerőművek elterjedésével a hagyományos erőművek által felhasznált fosszilis energiaforrások (pl. a szén) bent maradnak ugyan a földben, de cserébe az új technológia legyártásához a hagyományos anyagokból (beton, acél, alumínium, réz stb.) fajlagosan jóval nagyobb mennyiségekre lesz szükség. Emellett megnő a ritkán előforduló fémek (gallium, indium stb.) felhasználása, ami Európában, a lelőhelyek hiányában, új kockázatokkal jár. Summary. The topic of the study is to determine the material use of different power plant types. This is a part of the known life cycle analysis (LCA). The aim of LCA is to determine the impact of human activity on nature. The procedure is described in the standards (ISO 14040/41/42/42). Under environmental impact we mean changes in our natural environment, air, water, soil pollution, noise and impacts on human health. In the LCA, the environmental impact begins with the opening of the mine, continues with the extraction and processing of raw materials, and then with the production of equipment, construction and installation of the power plant. This is followed by the commissioning and then operation of the power plants for 20-60 years, including maintenance. The cycle ends with demolition, which is followed by recycling of materials. The remaining waste is disposed of. This is the complex content of life cycle analysis. Its purpose is to determine the ecological footprint of man. The method of the present study is to isolate a limited area from the complex LCA process. This means determining the amount of material needed to build different power plants, excluding mining and processing of raw materials. Commercially available basic materials are built into the power plant’s components. The research is based on the literature available in the international area. The author studied these sources, analysed the data, and checked the authenticity. It was not easy because the sources from different times, for different power plants showed a lot of uncertainty. In overcoming the uncertainties, it was a help that the author has decades of experience in the realisation of power plants. It was considered the material consumption related to the installed electricity capacity of the power plant (tons/MW) as basic data. The author then determined the specific material consumptions, allocated to the electric energy generated during the lifetime, in different power plants. The calculation is carried out with the help of the usual annual peak load duration hours and the usual lifetime of the power plants. The results show that with the spread of solar and wind energy, the fossil energy sources previously needed for conventional power plants will remain inside the Earth, but in exchange for the production of new technological equipment from traditional structural materials (concrete, steel, aluminium, copper and plastic), the special need multiplies. If we compare the power plants using renewable energy with the electric energy produced during the life cycle of a nuclear power plant, the specific installed material requirement of a river hydropower plant is 37 times, that of an onshore wind farm it is 9.6 times, and that of an outdoor solar power park is 6.6 times higher. Another important difference is that wind turbines, solar panels and batteries also require rare materials that do not occur in Europe (e.g. gallium, indium, yttrium, neodymium, cobalt, etc.). This can lead to security risks in Europe in the long run.
