The report also addresses various challenges hindering the adoption of green hydrogen, such as technological, economic and regulatory barriers. It calls for flexible and adaptive strategies to navigate these obstacles, ensuring the successful deployment and integration of hydrogen technologies. The report also addresses long-term planning, barrier identification, export considerations, target and priority setting, governance and policies, and provides a step-by-step methodology to guide the drafting of hydrogen strategies.

This report assesses the impact of weather-related variability on system operations across seasons and between years in different climatic zones.The analysis is based on a joint electricity and hydrogen dispatch model, newly developed for this report and incorporated into the Global Energy and Climate Model, representing hour-to-hour operations for all hours of the year.

The IEA report explores how carbon credits can incentivise their deployment.

This report indicates that 2023 set a new benchmark in renewable power deployment, adding 473 GW to the global energy mix, with solar energy accounting for 73% of this growth. Conducive policies, together with geopolitical developments and falling costs, have catalysed rapid renewable energy growth in the world's fastest-expanding markets.

The report shows analysis on the sector, based on current policies and market developments. It forecasts the deployment of renewable energy technologies in electricity, transport and heat to 2028 while also exploring key challenges to the industry and identifying barriers to faster growth
