Fossil Free Sweden has developed a strategy to use hydrogen to achieve the climate goals but also with a focus on new industrial initiatives to create innovations, jobs and export products."
	16.3.24. SK, Slovakia Hydrogen Strategy: Ready for the Future, "The National Hydrogen Strategy defines the strategic role of the state in use of hydrogen technologies in the Slovak Republic in the context of current development in the European Union member states."
	16.3.25. UA, UA Decarbonisation and the Green Deal: Ministry of Energy presents the draft Hydrogen Strategy, "The Ukraine Ministry of Energy presented the draft Hydrogen Strategy until 2050 during a working group meeting. The document contains up-to-date data on the development of hydrogen energy in the world, hydrogen classification and analysis of international legislation."
	16.3.26. UK, UK hydrogen strategy, "This strategy sets out the approach to developing a thriving low carbon hydrogen sector in the UK to meet our increased ambition for 10GW of low carbon hydrogen production capacity by 2030. The page includes hydrogen strategy updates to the market."


	16.4 NORTH AMERICA (2)
	16.4.1. CA, The Hydrogen Strategy, "The Hydrogen Strategy was released in December 2020, and positions Canada as a world-leading producer, user and exporter of low-carbon hydrogen and associated technologies. Natural Resources Canada engaged with stakeholder groups, provincial and territorial governments, and Indigenous partners to develop a strategy that will help set us on the path to meet our climate change goals of becoming net-zero by 2050."
	16.4.2. US, U.S. National Clean Hydrogen Strategy and Roadmap, "The U.S. National Clean Hydrogen Strategy and Roadmap explores opportunities for clean hydrogen to contribute to national decarbonization goals across multiple sectors of the economy. It provides a snapshot of hydrogen production, transport, storage, and use in the United States today."


	16.5 OCEANIA (2)
	16.5.1. AU, Australia’s National Hydrogen Strategy, "Australia’s National Hydrogen Strategy sets a vision for a clean, innovative, safe and competitive hydrogen industry that benefits all Australians. It aims to position our industry as a major global player by 2030."
	16.5.2. NZ, New Zealand’s hydrogen roadmap, "Development of a Hydrogen Roadmap was included as an action in the first Emissions Reduction Plan in 2022. The roadmap will outline the Government’s position on the future role of hydrogen in New Zealand and set out the pathway for establishing a hydrogen industry in Aotearoa New Zealand that will support the transition to net zero 2050."


	16.6 SOUTH AMERICA (5)
	16.6.1. BR, 2031 TEN-YEAR ENERGY EXPANSION PLAN, "Hydrogen has the potential to initiate a paradigm shift in the energy sector, bringing substantial opportunities to Latin America. The region can become a world leader mainly in low carbon hydrogen, considering the abundant and competitive renewable energy resources, as well as contributing to strongly decarbonize the region's industries and transportion sector."
	16.6.2. CL, NATIONAL GREEN HYDROGEN STRATEGY Chile, a clean energy provider for a carbon neutral planet, "Like hydrogen, Chile is small by nature and, accordingly, contributes just 0.3% to global greenhouse gas emissions. However, we too have an outsized role to play in turning the tide on rising emissions and pursuing a low carbon path to growth and development. What we lack in size, we more than make up for in potential. In the desert in the North, with the highest solar irradiance on the planet, and in the Patagonia in the South, with strong and consistent winds, we have the renewable energy potential to install 70 times the electricity generation capacity we have today. This abundant renewable energy will enable us to become the cheapest producer of green hydrogen on Earth. Our National Green Hydrogen Strategy is aimed at turning this promise into reality."
	16.6.3. CO, Colombia's Hydrogen Roadmap, "The purpose of the Hydrogen Roadmap is to contribute towards the development and implementation of low-emission carbon hydrogen in Colombia, thus reinforcing the Government's commitment to the reduction of emissions according to the objectives set forth in the 2015 Paris Agreement. In order to develop this Roadmap, the Colombian Government has the support of the Inter-American Development Bank (IDB) through its Energy Division and its Climate Change and Sustainability Division."
	16.6.4. PY, Towards the Green Hydrogen Roadmap in Paraguay, "This project, in the form of guidelines and a proposal for a demonstration project, aims to be a catalyst for the development of the green hydrogen (H2) economy in Paraguay aimed at meeting energy needs and contributing to producti- ve development. In addition, it is a comple- ment to national efforts to develop sustai- nable urban mobility as an alternative for the mitigation of the environmental and public health impact of mobility and trans- portation activities, which are responsible for poor air quality, noise pollution and increased temperatures in urban centers."
	16.6.5. UY, Green Hydrogen Roadmap in Uruqguay, "This roadmap is a first step to start setting a course in dialogue with many other stakeholders and in parrallel to drive concrete actions through the development of a specific program called H2U."
