Hydrogen has been recognized as a possible approach to the decarbonization of otherwise hard-to-abate sectors such as heavy industry or long-haul transport. In addition, hydrogen can provide a solution for long-term energy storage. By 2050 hydrogen could deliver up to 24% of the world’s energy needs. Despite its vast potential to decarbonize the energy system, high costs and unclear regulatory frameworks are obstacles to the emergence of a hydrogen economy. There is a need for coordinated action at national, subregional, and regional levels in the UNECE region to enable full commercialization of hydrogen projects. Across the UNECE region, countries are recognizing the potential for hydrogen to contribute to meeting the objectives of the Paris Climate Agreement. Regional and national hydrogen strategies have been developed in many UNECE countries, including Germany, the Netherlands, Russian Federation, Spain, United States and the European Union. In July 2020, the European Commission unveiled its “Hydrogen strategy for a climate-neutral Europe” (COM/2020/301) with the aim to boost clean hydrogen production in Europe and develop applications that would reduce greenhouse gas emissions across the industry, transport, power and buildings sectors. In July 2020, the United States published its “Hydrogen Strategy – Enabling A Low-Carbon Economy”, as a strategic plan to accelerate research, development, and deployment of hydrogen technologies. In October 2020, the Russian Federation approved a roadmap for the development of hydrogen energy until 2024 as a strategic plan to accelerate research, development, and deployment of hydrogen technologies. The objective of this project is to improve capacities of UNECE member States to develop sustainable hydrogen production strategies while raising awareness and overcoming economic, technical, policy and investment barriers.
