On May 11 and 12, 2023, the 3-Country Corrosion Conference will return to Frankfurt am Main as an in-person event for the first time since the coronavirus pandemic. The focus will be on corrosion processes in new CO2-free energy technologies. The event is being organized by relevant institutes, companies and universities from the DACH region. Galvanotechnik is supporting the event as a media partner.
The conference is supported by the Gesellschaft für Korrosionsschutz e.V. (GfKORR), Frankfurt, the Institute for Chemical Technologies and Analytics at the Technical University of Vienna/Austria, the Swiss Society for Surface Technology (SGO-SST), Grenchen/Switzerland, the Swiss Society for Corrosion Protection (SGK), Zurich/Switzerland and the Swiss Federal Laboratories for Materials Testing and Research (Empa), Dübendorf/Switzerland. In the run-up to the conference, reference is made to the rise inCO2 concentration in the atmosphere as the reason for the thematic focus: Since pre-industrial times, the carbon dioxide content of the atmosphere has risen by around 50% from 280 ppm to just under 420 ppm due to the burning of fossil fuels to generate energy. This has led to a progressive increase in the Earth's average global surface temperature by 1.2 degrees between 1880 and 2020. In order to halt this man-made climate change and its consequences, other energy generation technologies that cause no or significantly lowerCO2 emissions are increasingly being used or developed. In addition to "hydrogen", which is currently on everyone's lips as a replacement for fossil fuels, these include geothermal plants, thermal recycling processes for plastics and conventional nuclear reactors. The global demand for energy will be met now, but also in the future, from a mix of different technologies that is currently changing. Corrosion processes in these plants are often specific, sometimes novel, but in any case associated with serious consequences in the event of resulting plant failures, so that this topic will be taken into account at this year's 3-country corrosion conference due to its topicality.
The currently rapidly increasing importance of the topic of "hydrogen" and its effect on components of energy generation and existing infrastructure will be a particular focus of the conference. The relevant aspects of hydrogen embrittlement of steel will be discussed from a fundamental and applied perspective. Further key points of the program are corrosion phenomena in the production of secondary crude oil from plastic waste, corrosion processes in geothermal plants, high-temperature corrosion in molten salt for solar tower power plants and current crack formation phenomena in nuclear power plants.
