The principles of Findability, Accessibility, Interoperability, and Reusability (FAIR) have been put forward to guide optimal sharing of data. The potential for industrial and social innovation is vast. Domain-specific metadata standards are crucial in this context, but are widely missing in the energy sector. This report provides a collaborative response from the low carbon energy research community for addressing the necessity of advancing FAIR metadata standards. We review and test existing metadata practices in the domain based on a series of community workshops. We reflect the perspectives of energy data stakeholders. The outcome is reported in terms of challenges and elicits recommendations for advancing FAIR metadata standards in the energy domain across a broad spectrum of stakeholders.

In light of the content contained in this article, in the context of demographic change and globalization, there can be no doubt that education responding to contemporary challenges is a guarantee of promoting knowledge and profiling mobile and adaptive qualified staff characterized by having a specific level of knowledge, unique skills and highly developed qualifications. It is widely recognized that knowledge is the decisive factor in competitive advantage. The dynamics of changes taking place are conditioned by the resource and innovation of people’s knowledge, quality of work, education and training, the ability to think quickly and be innovative and implement new solutions in the process of production, distribution and services. The authors of the article justify why education should be seen as a value in all social and individual interactions, especially in a situation of economic change, globalization and demographic transition. It should refer to the inspiration of change, but also to the stabilization of people’s situations. Learning and education is therefore a modern value. Hence, it is important to perceive the strength and value of education in every social situation.

Dump fires are a significant environmental problem in post-mining areas. The TEXMIN project has shown that climate change could lead to more extreme weather events in the future, intense precipitation among them. The impact of water erosion on the development of endogenous fires in coal waste heaps has not been investigated thus far. Meteorological data collected from the studied dump area in Libiaz, Poland confirmed that heavy rainfall occurred many times, causing surface erosion on the slope. Gully erosion was observed on the western slope of the heap, the depth of which was up to 1.6 m. Data showed that between areas with and without water erosion, there was a significant difference in measured temperatures and gas concentrations that defined the fire intensity. Erosion facilitated self-heating such that internal temperatures increased to 52.9 degrees C. Further, at a depth of 1 m in the self-heating zone, maximum gas concentrations were 15.65 vol%. CO2 , 10 ppm CO, and 0.435 vol%. CH4 , while the O-2 concentration dropped below 1.0 vol%. These results show that despite preventative measures, thermal activity reactivated in the vicinity of gully erosion and caused the self-heating zone to expand.

This study examines the socio-technical challenges and public acceptance of hybrid pumped-hydropower storage (HPHS) technology within the broader context of energy transition in two European coal-mining regions: Western Macedonia, Greece, and the Łódzkie Region, Poland. These regions, deeply rooted in lignite mining, face profound socio-economic transformations driven by the EU Green Deal and its commitment to achieving net-zero emissions by 2050. The transition from coal dependency to renewable energy represents not only a critical environmental goal but also a significant socio-economic challenge for local communities, necessitating innovative and inclusive strategies to mitigate impacts and ensure equitable outcomes. The research integrates desk studies with stakeholder surveys (n = 129) to assess public awareness, perceived impacts, and acceptance of HPHS technology as a repurposing solution for decommissioned open-pit lignite mines. Results reveal that while awareness of the energy transition process is high (90% in Western Macedonia and 80% in Łódzkie Region), familiarity with HPHS technology varies significantly (76% and 48%, respectively). Support for implementing HPHS in former mining sites is stronger in Western Macedonia (73%) compared to Łódzkie Region (63%), with knowledge of HPHS correlating positively with acceptance (r = 0.83, p < 0.01). Both regions recognize the environmental benefits of HPHS, including improved air quality and biodiversity; yet, socio-economic challenges such as job losses, reduced income levels, and limited opportunities for reskilling persist, particularly in Łódzkie Region, where 77% of respondents view the energy transition as negatively impacting the labor market. By focusing on regions historically dependent on mining, this study highlights the critical role of addressing the unique needs of communities undergoing systemic transformation. The repurposing of former lignite mines into HPHS facilities offers a promising pathway for balancing environmental objectives with local socio-economic revitalization. However, success requires region-specific strategies, including transparent communication, stakeholder involvement, and targeted investment in workforce adaptation and infrastructure. These findings contribute to the growing discourse on how socially inclusive and technically feasible solutions can drive equitable energy transitions in post-mining regions.

With climate change, more intense weather events are observed, including pressure drops associated with the arrival of atmospheric fronts. These pressure drops are the primary cause of gas emissions from closed mines to the surface, with inactive mine shafts serving as the most likely emission pathways. The most significant emitted gases are carbon dioxide and methane, posing a dual challenge: greenhouse gas emissions and gas-related hazards. This study analyses changes in gas emission intensity in response to short-term (hourly) pressure fluctuations. Additionally, it presents the results of gas emission measurements from an inactive shaft, considering the impact of temperature differences between the air and emitted gases. The findings indicate that gas emissions are subject to inertia, which is crucial for gas monitoring around mine shafts, as emissions may still occur in the early stages of a pressure increase. Furthermore, the results show that temperature differences between the atmosphere and emitted gases could have a major influence on the process.
