Innovation & Technology
How Is Hydrogen Made?
Steam methane reforming and coal gasification, then electrolysis in three ways – production methods differ widely in efficiency, CO₂ footprint and price per kilogram.
The Age of Hydrogen – Why Now?
We have talked about the Earth's lightest element as a potential energy carrier for decades – for the first time, it looks as if the hope is coming true.
The New Age of the Electric Motor
The electric motor was not invented yesterday – but it has never been reinvented as radically as now: rethinking magnetic flux, the dual-rotor principle and the rare earth question are together rewriting the future of electric propulsion.
China's Water Industry Boom, Up Close
Zsolt Eszes, CEO of Water4All, visited IE expo 2026 in Shanghai, China's second-largest water industry trade fair, with his colleagues. We asked him about his experiences.
The Ocean's Hidden Energies
While offshore wind is already a proven industrial reality, two emerging technologies – wave energy and tidal stream energy – are just now moving from the laboratory to the open sea.
Nano-Cages Against Forever Chemicals
Australian researchers have developed a reusable adsorbent made of nanoscale molecular cages that removes up to 98% of PFAS pollutants from water – including the hardest-to-treat short-chain variants.
Fifty Years of the Battery – and What Comes Next
From the lithium-ion revolution to solid-state batteries: where does energy storage technology stand today, and where is it heading in the next decade?
Wind at Sea – the Decade of Offshore Energy
Wind farms built at sea are not only one of the fastest-growing segments of the energy sector – they could become a critical pillar of the entire renewable energy mix.
Activated Carbon Against PFAS
New research shows that above 500 °C the surface of activated carbon acts as a catalyst in breaking down PFAS – but the environmental cost of the process is not negligible.
The Battery Wall, Blooming Wastewater and the Power-Generating Window
Researchers offer three eco-friendly innovations that, if widely adopted, could significantly improve the efficiency of energy generation and wastewater treatment.
