Une promesse complexe
Une aviation climatiquement neutre n’implique pas seulement de réduire les émissions des vols. Une étude du PSI analyse ce qui sera nécessaire pour atteindre cet objectif à long terme.

Où doit être produit l’hydrogène à l’avenir?
Des scientifiques du PSI ont étudié où l’hydrogène devait être produit pour une future économie de l’hydrogène et quelles étaient les conséquences de cet agent énergétique pour l’environnement.
Hydrogène: suffisamment propre pour le tournant énergétique?
L’hydrogène peut jouer un rôle déterminant dans la transition vers un système énergétique zéro net. Mais pour ce faire, il doit être produit correctement.
Climate-neutral aviation: will it fly?
The European aviation sector stands at a pivotal juncture in its quest to achieve net-zero climate impacts. Focusing on flight CO2 emissions overlooks up to 80% of the sector's climate repercussions.
Our research delves deep into the role of electricity-based synthetic jet fuels and direct air carbon capture and storage (DACCS) as potential game-changers. These solutions promise climate-neutral aviation, but there's a catch: the relentless rise in air traffic. Relying solely on renewables-derived synthetic fuels may strain both economic and natural resources. On the flip side, offsetting fossil jet fuel impacts via DACCS poses its own set of challenges. Our findings underscore one clear message: for a genuinely climate-neutral European aviation, we must reconsider the scale of air traffic.

Comment réduire la quantité de cobalt dans les batteries des voitures électriques?
L'électrification des transports est en augmentation. Cela signifie que davantage de batteries sont nécessaires. Cependant, certaines d'entre elles contiennent une matière première extrêmement problématique : le cobalt. Le PSI recherche des alternatives.
L’avion climatiquement neutre: est-ce possible?
Pour atteindre cet objectif, il faudra avant tout disposer de carburants durables et réduire le trafic aérien.

Evaluation of European electricity supply resilience
The increasing risk of extended electricity supply disruptions and severe electricity price fluctuations strongly motivate an evaluation of electricity supply resilience. In this direction, this research proposes a multicriteria decision support framework to assess resilience at a country level, based on three major dimensions: Resist, Restabilize and Recover. In total, 35 European countries are ranked according to their performance on 17 indicators, through a synergy of MCDA methods, techniques and communication protocols. The assessment framework has been extended to incorporate the Choquet Integral method, in order to accommodate potentially interacting pairs of criteria and negate their arbitrary effects on the final evaluation results. The analysis incorporates country data from credible international databases, as well as the preference information of a European energy expert. The results are envisaged to support energy policymakers in Europe and provide guidelines and areas for improvement at a country level.
E-fuels and electrification as complementary approaches to achieve climate target
Sustainable, synthetic fuels, so-called e-fuels, can help reduce CO₂ emissions. For their production, electricity from renewable sources is required in order to allow for a close to CO₂-neutral balance. The availability of electricity from renewable sources, which ensures the climate benefits of e-fuels, is currently still limited. “Especially in order to produce on a larger scale, a lot of renewable electricity is needed,” explains Christian Bauer, researcher at the Laboratory for Energy Systems Analysis (LEA) at PSI.
