Description du projet
La quête de la fusion froide: une solution aux besoins énergétiques mondiaux?
En 1989, les électrochimistes Martin Fleischmann et Stanley Pons ont défrayé la chronique en affirmant avoir produit un excès de chaleur à l’aide d’un simple appareil fonctionnant à température ambiante. Leur expérience consistait à forcer un métal, le palladium, à absorber du deutérium. Étant donné que de nombreux expérimentateurs ont échoué à reproduire leurs travaux, la fusion à froid reste un sujet controversé dans la communauté scientifique. Néanmoins, une minorité de chercheurs véhéments croit toujours que ce phénomène insaisissable est possible. Depuis 2015, Google finance des expériences sur la fusion à froid. Bien qu’aucune preuve de ce phénomène n’ait été apportée, il est clair qu’il reste encore beaucoup de recherches pionnières à mener dans ce domaine encore peu étudié. Le projet HERMES, financé par l’UE, utilisera des techniques et des outils avancés développés au cours des dernières décennies pour étudier les effets anormaux observés sur le palladium chargé de deutérium, à des températures ambiantes et intermédiaires.
Objectif
Disruptive energy generation technologies are urgently required to stave off catastrophic climate change. Now, more than ever, is the time to also to consider unconventional options. The subtopic c. Breakthrough zero-emissions energy generation for full decarbonisation of this call aims to answer this need. All of the research areas identified by the call are highly unconventional. As electrochemists, we will contribute to this call by working on hydrogen-metal systems. We propose to study hydrogen (and deuterium) evolution in unconventional conditions, i.e. on metal-hydrides and the main motivation for this work is based on the recent Nature perspective “Revisiting the cold case of cold fusion”. When loading deuterium into the Pd lattice, there is a chance that something very interesting will happen, resulting in production of excess heat. The first report of such reaction was published 30 years ago, but quickly dismissed by the scientific community. But what if there is really something? Can we afford to not to investigate this further, considering the current climate crisis? Google has recently funded a research project in this area, getting some interesting results but failing to produce excess heat. However, the team concluded that it was very difficult to achieve the required conditions reported for starting the excess heat production, and that “there remains much interesting science to be done in this underexplored parameter space.” This is a high risk/high reward project, but with aid of all the improved techniques and tools developed in the last 30 years, we believe that it is worth revisiting the topic. We will use state-of-the-art technologies to prepare, characterize and study electrochemical Pd-D system, both at room temperature and at temperatures up to 1100 K. We will focus on method development, with the special emphasis on reproducibility. If no nuclear effects are observed, we will gain information of the isotope effects for hydrogen evolution.
