Harnessing solar energy and green hydrogen – the energy transition

Abstract

The article presents various aspects of harnessing solar energy and green hydrogen which is one of the objectives of the EU and Poland’s energy transition. Theoretical issues were examined on the basis of the analysis of available source literature on renewable energy sources (RES), green hydrogen and energy transition. The research methods used in this paper include: critical analysis of the source literature, comparative analysis method and secondary data analysis. The article describes actions taken in Poland to facilitate the energy transition associated with harnessing solar energy and green hydrogen and presents author’s diagram of energy transition related to RES and green hydrogen in EU and Poland. The analysis and assessment carried out in the article indicated that the new concept of operation of the entire energy market and its transition involves the integration of three sectors: transport, heat engineering and power engineering. In the future, green hydrogen will enable a reduction of CO2 emissions from the power engineering and heat engineering sector to zero. Importantly, the electrification of heat engineering and transport based on domestic renewable energy sources will render Poland independent of the energy resources from other countries. The issues as presented in the article concerning renewable energy sources, green hydrogen and energy transition have not been collectively studied in Polish and foreign literature.
