Renewable energy sources have become a key research focus in the field of global environmental governance. Within this context, new technical innovations seek to overcome challenges resulting from volatile renewable energy production and a lack of storage capacities. Blockchain, a distributed ledger technology using cryptography, has gained prominence as an integral component within the increasingly decentralized and digitalized global energy infrastructure. Against this background, Alexander Freier argues that the application of blockchain technologies represents a viable option to enhance the efficiency and balancing of renewable energy as well as to subsequently reduce greenhouse gas (GHG) emissions if the following three components are met: the ongoing implementation of technological advancements, an adequate global normative framework, and general trust on the part of key market actors to promote blockchain in the energy sector on a global scale. Departing from an analysis of the relationship between climate change and energy, Freier conducts a legal analysis to explore possible "bottom-up" perspectives for the implementation and transfer of technological innovation derived from climate contracts. This analysis examines the technological infrastructure surrounding blockchain energy as well as its application to the Brooklyn Microgrid in the US and the WindNODE trading platform in Germany from an International Relations perspective.

Alexander Freier studied Political Science and holds a doctorate in Global Studies from the University of Leipzig, Germany. He earned a double Master¿s degree in Business Administration and International Business Administration from the Catholic University of Cordoba, Argentina, and the European University Viadrina Frankfurt/Oder, Germany. He is former professor of International Relations at the Catholic University of Cordoba, Argentina, and Research Associate at the Centre for Blockchain Technologies at University College London, United Kingdom. Since 2021, he has also been responsible for Strategy and International Affairs at the renewable energy project development company Energiequelle GmbH, Germany. His research focuses on the nexus between renewable energy and climate change policies. Since 2019, he has been exploring the opportunities to implement blockchain-based solutions in the energy sector as well as their potential to serve as climate technologies. His most recent research project focused on the usage of renewable energy to enhance the sustainability of Proof-of-Work mining.
