The workshop aims to highlight the main areas of advanced and sustainable energy science and associated technological applications. The challenges for clear energy will be discussed with special attention to hydrogen related technologies.

The workshop is organized in the context of ARCHERS (https://archers.iesl.forth.gr/ [3]), a major project implemented by FORTH with the exclusive donation of the Stavros Niarchos Foundation (SNF). Through ARCHERS, over 100 young doctoral students and post-doctoral researchers have been supported over the past four and a half  years and have carried out cutting-edge research in the Institutes of FORTH across a broad range of interdisciplinary thematics including preservation of cultural heritage and tackling of societal challenges such as environment, clean energy and health.
