A recent study published in the journal Energies explores the potential for green hydrogen production through innovative Power-to-Gas (P2G) systems integrated with floating photovoltaic (FPV) installations on pit lakes in former mining sites in Poland. Led by Mateusz Sikora from the Faculty of Civil Engineering and Resources Management at AGH University of Krakow, this research highlights a promising avenue for sustainable energy production and contributes to the European Union’s climate goals.
As Europe aims for a 55% reduction in CO2 emissions by 2030 and strives for climate neutrality by 2050, the demand for green hydrogen as an alternative energy source is growing. Sikora’s study indicates that these P2G systems could effectively harness renewable energy from FPV facilities, converting it into hydrogen through electrolysis. This hydrogen can then serve as a versatile energy carrier, capable of powering zero-emission vehicles, particularly city buses in urban areas.
The research focuses on the West Pomerania province of Poland, where abandoned mining sites, specifically pit lakes, present a unique opportunity. These sites, often viewed as environmental liabilities, can be transformed into productive energy assets. Sikora notes, “Integrating FPV systems with P2G technology at former mining sites presents a significant opportunity for green hydrogen production.” By 2050, the study forecasts that these systems could support a fleet of up to 900 hydrogen-powered buses, significantly contributing to urban mobility and reducing emissions in major cities.
The study employs advanced Geographic Information System (GIS) tools to identify suitable locations for these installations, assessing their capacity for hydrogen production and modeling the timeline for site availability. This method not only provides a roadmap for future developments but also offers insights that can be applied globally, particularly in other European Union member states with similar post-industrial landscapes.
Commercially, the implications of this research are substantial. The integration of FPV systems with P2G technology could lead to the development of decentralized hydrogen production facilities that require less extensive infrastructure than traditional systems. This could lower the barriers for investment and operation, making hydrogen production more accessible and economically viable. Sikora emphasizes the potential for “decentralised, small-scale FPV-P2G installations to serve as key elements of a national green hydrogen production strategy.”
Furthermore, the study aligns with Poland’s energy policy goals, which aim for a significant increase in renewable energy sources and a reduction in greenhouse gas emissions. By utilizing existing post-mining areas, the research not only addresses energy production but also contributes to land reclamation and environmental remediation efforts.
In summary, Sikora’s research presents a compelling case for the role of green hydrogen in the energy transition, particularly through the innovative use of former mining sites. As the energy sector continues to evolve, the findings from this study could pave the way for new commercial opportunities and contribute to a more sustainable future.
