On 14 July 2020, the European Commission adopted a set of proposals to make the EU’s climate, energy, transport, and taxation policies fit for reducing net greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels. The Irish government is committed to a long-term decarbonisation pathway for the Irish energy system leading to a reduction in greenhouse gas emissions from the energy sector of between 62% and 81% on
1990 levels by 2030. Imagine a world where renewable electricity is produced day and night, meets grid demand, and the residual supply is used to produce green fuels such as hydrogen. This vision can easily become reality, with the use of large-scale energy storage systems. In particular, thermal energy storage systems, also known as thermal batteries, are ideal candidates for such purpose, since renewable energy can be cost-effectively
stored in the form of heat and returned later to the grid when demand is high. The stored heat is converted to electricity with the use of a heat engine. The goal of this seminar is to introduce to the audience a low-cost and highly efficient thermal energy storage system for renewable energy sources by modifying Limestone dust. Efficient and cost-effective energy storage is the main challenge if renewable energy is to become reliable and eventually replace fossil fuel power. A new class of energy materials that will overcome the challenges of new clean energy sources and storage technologies that are efficient, cost-effective and reliable, will be presented


Veronica Sofianos is a Materials Scientist with a PhD in Chemistry. She joined the UCD School of Chemical and Bioprocess Engineering in 2020 as an Ad Astra Fellow to start her independent academic career. Prior to that she was a research fellow at Curtin University in Perth, Australia. Her current research is focused on the synthesis and characterisation of low-cost and high-performing nanomaterials for either (i) energy storage or (ii) generation.
The (i) strand of research is focused on nanomaterials used as additives to significantly improve the efficiency and cycling stability of high-temperature thermal batteries for long-term renewable energy storage. The (ii) second strand of research is focused on nanomaterials used for the electrocatalytic production of hydrogen in aqueous solutions of a wide pH range.
