System impacts of wind energy developments: Key research challenges and opportunities
McKenna, Russell; Lilliestam, Johan; Heinrichs, Heidi U.; et al. (2025)
Joule
Wind power accounted for 8% of global electricity generation in 2023 and is one of the cheapest forms of low- carbon electricity. Although fully commercial, many challenges remain in achieving the required scale-up, relating to integrating wind farms into wider technical, economic, social, and natural systems. We review the main challenges, outline existing solutions, and propose future research needed to overcome existing problems. Although the techno-economic challenges of grid and market integration are seen as significant obstacles to scaling up wind power, the field is replete with solutions. In many countries, planning and permitting are immediate barriers to wind-power deployment; although solutions are emerging in the EU and several countries, the effectiveness and long-term acceptance of fast-track permissions and go-to areas remains to be seen. Environmental impacts on wildlife and recycling challenges are rising issues for which tested and scalable solutions are often still lacking, pointing to large remaining research requirements.

Carbon capture and utilization: More than hiding CO2 for some time
Mertens, Jan; Breyer, Christian; Arning, Katrin; et al. (2023)
Joule
Professor Jan Mertens is ENGIE's chief science officer (CSO) build-ing ENGIE's long term vision on technologies, identifying key in-ternational research players on selected emerging technologies, and initiating research partner-ships worldwide for the group. Since 2019, Jan is also part-time professor at the University of Ghent in the domain of sustain-able energy. He holds a PhD in environmental engineering from the Katholieke Universiteit Leuven (2006). His main research topics are related to emerging energy technologies, sustainabil-ity assessment including life cycle assessment, emissions moni-toring, carbon capture, carbon use, and water footprinting.
A p-type Cu2O photoanode for solar water oxidation
Bae, Sanghyun; Moehl, Thomas; Yong, David; et al. (2025)
Joule
The development of efficient, stable, and earth-abundant photoanodes for solar water oxidation is critical to advancing photoelectrochemical and photocatalytic systems for large-scale renewable fuel production. Here, we demonstrate that p-type Cu2O, typically studied as a photocathode material, can be used as a high-performance photoanode through judicious engineering of charge carrier-selective contacts on thermally oxidized Cu2O sheets. The introduction of Ga2O3, TiO2, and indium tin oxide (ITO) layers as an electron-selective back contact, combined with Al2O3, Au, and Ni front layers, significantly enhanced charge separation and electron transfer. The champion Cu2O photoanode exhibited a photocurrent density of 8.65 mA cm⁻² at 1.23 V vs. the reversible hydrogen electrode in alkaline media, which is the highest reported for metal oxide photoanodes. These findings highlight the pivotal role of charge carrier-selective interface engineering in broadening the scope of available semiconductor materials for photo(electro)catalytic oxidation reactions, irrespective of the doping type of the light-absorbing material.
Support was the key to success
Ramirez Galilea, Adrian; Gascon, Jorge (2020)
Joule
Dry methane reforming, the conversion of carbon dioxide and methane (the two main gases responsible for global warming), into a useful feedstock for the production of materials is a process known since 1928. However, fast catalyst deactivation, due to the formation of carbon deposits on the surface of the catalyst, has since its discovery hampered industrial application of this key process. In a recent article in Science, Cafer Yavuz and colleagues reveal that the key to catalyst stability is in the use of a single-crystalline support.

Skills-based and regionally explicit labor market exposure to the low-carbon transition in Europe
Zaussinger, Felix; Schmidt, Tobias; Egli, Florian Manuel (2025)
Joule
Transitioning to a low-carbon economy leads to shifts in the labor market. Yet, an effective policy response to such shifts is currently limited by knowledge gaps on the occupations at risk, their skill profiles, and their regional and sectoral distributions. Here, based on a novel classification of occupational exposure covering 3,008 occupations and 13,500 skills, we map the labor market exposure to the low-carbon transition across European regions and sectors using granular labor force surveys. We find that workers in high-carbon jobs lacking industry decarbonization options (at-risk jobs) have significantly fewer skills and that their skills are less transversal compared with low-carbon or neutral jobs, which may inhibit switching to in-demand occupations. Moreover, large variations between regions and sectors can be expected. For example, while at-risk jobs are most frequent in the mining sector in relative terms (11%), the manufacturing sector is most affected in absolute terms (0.9 M). Crucially, our approach shows that effective deployment of industry decarbonization options helps reduce the number of at-risk workers from 6.2 to 2.3 M. Finally, we show that, among European countries with available data, Germany and Hungary face a particular challenge with a disproportionately high share of their workforce at risk, combined with low public support via the EU Just Transition Fund. Responding to these national and regional labor market impacts is critical to avoid policy backlash.
