A recent study conducted by an international team of contributors and described in a University of Amsterdam report delves into the expected contributions of renewable energy sources and hydrogen in Europe's race to reduce carbon pollution and achieve 'net-zero' goals by 2050. The study, published in the journal Nature Communications, projects that by 2050, end-use 'final energy consumption' from electricity and hydrogen may average around 60% and 6%, respectively, in a deep decarbonization scenario. The research highlights the importance of renewable-based electrification as the most cost-efficient decarbonization route for the economy, with hydrogen playing a critical role in specific decarbonization pathways, particularly in heavy industry and transportation sectors. Despite the potential of hydrogen, challenges such as production methods that often involve burning natural gas and the existing advantages of wind and solar energy in terms of costs and infrastructure present hurdles. The study underscores the need to optimize the use of hydrogen in economic sectors where it can have the highest impacts, such as steel-making and heavy-duty vehicles. The research is part of a collaborative effort by European institutions to establish evidence-based policies for reducing CO2 emissions, considering the interplay between different economic sectors. The modeling work assesses 'final energy consumption,' focusing on the direct use of renewable electricity and hydrogen in fuel cells for various applications. Future studies will explore hydrogen's intermediary role in enabling sustainability transitions, such as energy storage to address the intermittency of solar and wind power sources. Overall, the study's findings contribute to Europe's efforts to balance the growth of renewable electricity and hydrogen production in achieving deep decarbonization. The ongoing research aims to quantify the requirements for large-scale renewable electricity production to meet the ambitious net-zero 2050 targets set by European policies.
