Green hydrogen: Pathways, roadmap, and role in achieving sustainable development goals

The United Nations Sustainable Development Goals (UN-SDGs) provide a unique opportunity to achieve sustainable development and reduce climate change impact. Decarbonizing the energy system is a key approach to achieving the energy balance. Recently, green hydrogen has become the most promising energy source for decarbonizing energy systems. Therefore, determining the different production methods of green hydrogen, their economics, and their environmental impacts is essential to all stakeholders. Additionally, understanding the role of green hydrogen in achieving the different SDGs is vital for policymakers and decision-makers. Thus, this study reviewed the common hydrogen production methods. The prospect of achieving the SDGs has also been investigated, and the most relevant keywords were presented. Finally, a list of indicators (guidelines) to increase the green hydrogen contribution to the SDGs was provided. The provided indicators will assist the stakeholder in increasing the integration of green hydrogen into the SDGs and reduce the trade-off.
