This dissertation investigates the economic competition among green technologies in the context of the energy transition, with a particular focus on low-carbon hydrogen. Beyond the classic "grey-to-green" paradigm that models cleaner technologies replacing fossil-fuel-based alternatives, this work emphasizes the increasingly relevant competition within green technologies.

Hydrogen valleys, which integrate renewable energy sources, hydrogen infrastructure, and end-use applications, play a crucial role in decarbonizing industrial energy hubs. However, the large-scale deployment of hydrogen is constrained by limited renewable electricity availability and high technology costs. A key insight from our analysis is that the merit order of hydrogen end-uses is dynamic, evolving...

Electric batteries and fuel cells (hydrogen) are competing technologies for the energy transition in heavy transportation. This paper shows that the existence of a market niche for fuel-cell electric buses (FCEBs) can be obtained depending on the values of a limited set of key parameters.

This one-day workshop brings together researchers working on the design, evaluation, and impact of climate policies aimed at fostering the development and diffusion of low-carbon technologies. The presentations will cover a range of topics including the regulation of urban transport emissions, the integration of carbon dioxide removal into energy markets, the strategic adoption of...

Les Chaires Armand Peugeot, Énergie et Prospérité, et Économie du Climat organisent, les 6 et 7 décembre 2023, la 10ème édition de la conférence internationale annuelle sur les enjeux liés à la mobilité.

The objective of the conference is to improve our understanding of the interaction between climate and innovation policies in this multi-layer governance landscape by bringing together scholars in economics working on innovation policies, international environmental agreements, and environmental federalism.
