Hydrogen Production and Infrastructure Projects Database
Tracks data on projects for the production of hydrogen for energy or climate change-mitigation purposes and the development of hydrogen infrastructure The IEA produced these datasets as part of efforts to track advances in low-emissions hydrogen technology.The Hydrogen Production Projects Database covers all projects commissioned worldwide since 2000 to produce hydrogen for energy or climate change-mitigation purposes. It includes projects that have the objective either to reduce emissions associated with producing hydrogen for existing applications, or to use hydrogen as an energy carrier or industrial feedstock in new applications that have the potential to be a…

11th Annual Global Conference on Energy Efficiency
See more Agenda OverviewEnergy efficiency is a top priority for governments worldwide as they work to ensure energy security and affordability while reducing emissions. Despite this, global progress has slowed over the past few years, locking in wasted energy, higher costs, and increased emissions.The IEA Annual Global Conference on Energy Efficiency is the leading international forum for advancing energy efficiency. Each year, it brings together ministers, CEOs, and senior leaders from government, finance, and business sectors across the globe.Many governments are implementing policies to boost energy efficiency, and the IEA’s Global Conference on Energy Efficiency aims to…

Thematic session: New frontiers in modern and efficient data centres
…will bring together global leaders to accelerate action, with data centres emerging as a key focus due to their rapidly growing electricity demand.Data centres are critical infrastructure for digital and energy transitions, but their electricity use is rising quickly. The IEA estimates their electricity consumption was nearly 500 terawatt hours (TWh), or about 1.5% of global electricity consumption in 2025, and will double by 2030. Ensuring efficient and flexible electricity use is therefore essential to balance data centre growth with grid resilience. This requires smarter design and operation of data centres, stronger integration with power and heat networks…
