Global Hydrogen Review 2026 Key questions about hydrogen
How has the conflict in the Middle East affected supplies of fertilisers and chemicals made from hydrogen? The conflict in the Middle East has disrupted not only oil and gas flows, but also global supply chains for hydrogen‑based products, particularly fertilisers and chemicals such as ammonia, urea and methanol. These products account for a large share of hydrogen demand, with ammonia and methanol alone representing roughly half of global consumption.The Middle East plays a critical role in global markets for hydrogen-based products, and a large share of its production is dedicated to exports, making the region a major…

Multiple Benefits of Energy Efficiency for Business Quality and reputation
Greater efficiency can reduce defects and improve production quality Energy efficiency improvements often involve tighter control and optimisation of production processes. By improving precision and stability in how equipment operates, firms can reduce variability in output and limit the occurrence of defects. These effects are particularly important in manufacturing sectors where small deviations can affect product quality and increase waste.For example, an industrial bakery in Switzerland implemented a highly efficient centralised cooling system with CO₂-refrigerant and advanced controls. The system allowed for a more constant controlled temperature and reduced downtime, improving product quality and consistency, all while reducing…

Global Energy Review 2026 Technology: Heat pumps
Global heat pump sales fell by about 2% in 2025. Sales in China and Japan were largely flat, while Europe saw a strong return of demand. Sales in the United States declined.In China, heat pump sales stayed broadly stable. Reversible air conditioners (used as primary heating equipment) make up about half the Chinese heat pump market, and while record-breaking sales of air conditioners supported strong demand in the first half the year, they fell sharply in the second half. Sales of air-to-water and hot water heat pumps, which make up the remainder of the market, remained…

Global Hydrogen Review 2026 Investment and innovation
Capital spending on low-emissions hydrogen projects reached nearly USD 7 billion in 2025, nearly double the 2024 level and equal to 0.7% of global investment in energy supply. Investment in electrolysis overtook investment in carbon capture, utilisation and storage (CCUS)-based hydrogen, thanks to a stronger pipeline, higher capital intensity and faster project progress, and could account for around 70% of nearly USD 10 billion in investment in 2026.China and Europe lead committed electrolysis projects, with China accounting for more than 60% of capacity by 2026 and 25% of estimated investment. Europe represents less than 20% of capacity but 45% of…
