We are at a crossroads and an historic moment in history having passed the threshold for the Paris Agreement to enter into force. Fifty-five countries accounting for greater than 55% of emissions have joined the climate agreement. This establishes a new era of global consensus on climate change action. Undoubtedly, this agreement will further accelerate development of a vast market for clean energy technology solutions that reduce net emissions of greenhouse gases. The hope and optimism of this agreement is tempered by the lack of a roadmap to achieving the goals in the short time remaining before the carbon budget is exhausted. The central challenge will be to accelerate the deployment of affordable and scalable clean energy technologies, develop new innovative low or negative emissions solutions rapidly, meet the declared nationally determined goals, and build momentum to inspire ever greater ambition. One technology platform based on concentrating solar and a special class of solid state ionics materials, which can contribute to addressing this central challenge in multiple ways, has not yet gotten much attention. Here we focus on the prospects for that class of materials and processes, namely redox-active mixed ionic-electronic conduction (MIEC) metal oxides and thermochemical redox cycles, and how they might play an important role in climate action. Toward that end, this symposium will highlight advances in redox active MIEC metal oxides and thermochemical cycles, inclusive of a number of applications, such as thermochemical energy storage, thermochemical water and carbon dioxide splitting, chemical looping, oxygen removal from sweep gases, and ammonia production. Presentations will focus on materials discovery, classes of materials, and recent progress or challenges in rational design of the materials via computational materials science, experimental characterization methods, and fit for purpose reactor and system designs.


Abstracts are solicited in, but not necessarily limited to, the following areas:

In this Symposium are also welcome those contributions which cover the topics beyond the above-described areas. This is done to provide the audience with a comprehensive description of Solid State Ionics. If your contribution is difficult to host within the above areas, please do not hesitate to contact directly the Conference Chairmen at ssi21@dii.unipd.it for advice.
