Global Hydrogen Review 2026 Production
Global hydrogen production remains dominated by unabated fossil fuels. Low-emissions hydrogen production reached almost 1 Mt in 2025 and is expected to register record growth in 2026, accounting for more than 1% of global production, strongly concentrated in China, Europe and North America.Installed electrolysis capacity doubled in 2025 to surpass 4 GW, thanks to the commissioning of several large-scale projects in China. More than 2.5 GW are under construction, targeting operation in 2026. Growth is expected mostly in Europe, with 2 GW, but is highly concentrated in a small number of big projects.One large project for production from fossil…

Multiple Benefits of Energy Efficiency for Business The business value of energy efficiency
Energy efficiency is often described as the “first fuel” because the cheapest and most secure energy is the energy that is not used. For businesses, this begins with a straightforward benefit: lower energy bills. In many cases, efficiency investments can pay back quickly through reduced energy costs alone, improving margins and reducing exposure to price volatility.However, the value of energy efficiency extends beyond energy savings. By improving how equipment, buildings and processes operate, efficiency measures deliver wide-ranging benefits that strengthen business competitiveness across several dimensions: Operational benefits Efficient and electrified equipment operates more reliably and with less stress…

Global Hydrogen Review 2026 Cost acceptability
Analysis of the costs of hydrogen in different end-uses enables identification of the maximum acceptable costs for hydrogen users, i.e. the maximum amount that can be spent on the hydrogen feedstock within a low-emissions pathway while maintaining the same total levelised cost of production as the incumbent pathway to produce the same commodity.This can enable policy makers and investors to identify sectors with both high maximum acceptable hydrogen costs and high potential volumes that can serve as lead markets for low-emissions hydrogen. Cost acceptability can be influenced by policies and depends on technologies, fuels and…
