The global shift towards clean energy has accelerated the growth of the hydrogen economy, with a particular focus on carbon-neutral energy sources. In line with this trend, the EU's Fit for 55 package is driving significant investments in hydrogen development. Finland, specifically the city of Espoo, is strategically positioning itself to take a leading role in the European hydrogen economy, with a strong emphasis on utilizing renewable hydrogen in energy and transportation sectors. A recent report by Sasu Nuokkola, M.Sc, for the City of Espoo delves into the potential of hydrogen within the city, shedding light on the importance of hydrogen in the green transition. The report not only provides an overview of hydrogen and its applications but also gathers insights from key stakeholders in Espoo regarding the current and future prospects of hydrogen. With a focus on leveraging Espoo's expertise in hydrogen technology and research, stakeholders see a promising opportunity for growth in the hydrogen sector in the coming decade. The report, part of the Innovation Challenge Engine for Cities project, aims to drive sustainable urban development through collaboration with various stakeholders. While the report is currently available only in Finnish, it serves as a valuable resource for understanding Espoo's role in advancing the hydrogen economy and fostering innovation in sustainable urban development.
