52nd International Conference of Slovak Society of Chemical Engineering (SSCHE)

From 26 – 29 May 2026, the 52nd International Conference of SSCHE (Slovak Society of Chemical Engineering) was held at the SOREA TRIGAN Hotel in Štrbské Pleso, Slovakia.

During the conference, research results obtained within the project entitled “Hybrid Energy Storage System Using Post-Mining Infrastructure” (HESS, Grant Agreement No. 10111280) were presented. The project is co-funded by the Research Fund for Coal and Steel (RFCS) and the Polish Ministry of Science and Higher Education.

The annual SSCHE International Conference brings together researchers and professionals working in chemical and process engineering, environmental engineering, and energy transition. The event attracts participants from many countries, with particularly strong representation from the Visegrad Group countries, namely Poland, the Czech Republic, Slovakia, and Hungary.

As part of the conference programme, Janusz Lasek, representing ITPE, delivered a presentation entitled “Analysis of Hybrid Energy Storage Systems Using Post-Mining Infrastructure, Including Day-Ahead Market (DAM) and System Operating Cycle Characteristics”, authored by Krzysztof Głód, Krzysztof Supernok, Agata Czardybon, and Janusz Lasek. The presentation focused on the integration of a new hybrid energy storage concept with the centralised energy system, including the role of the day-ahead market (DAM) in optimising the economics of energy conversion.

The study analysed a hybrid energy storage system based on the use of post-mining infrastructure and considered the operating cycles of a pumped storage hydroelectric power station (PSH). Three storage concepts were compared: CO₂ compression, air compression, and conventional pumped storage hydropower. The analysis showed that the most favourable configuration in terms of unit profit was obtained for the CO₂-based system with medium-level storage capacity of 42 MWh.
