Britain's Budget Leaves Biomethane Support Frozen
The UK Budget found money for hydrogen but none to lift the cap on biomethane support, while Spain tightened its oxygen limit for grid injection, drought cut Europe's maize silage harvest and Polish sugar mills lined up as biomethane hosts.
The Decade of Fusion Energy Begins
…take, and why is it so hard? In nuclear fusion, light atomic nuclei – typically the hydrogen isotopes deuterium and tritium – fuse into a heavier element, releasing an enormous amount of energy. This is the same process that takes place inside the Sun,…
A Trunk Sewer Collapses Near Washington
…wall thickness and the structural integrity of the pipe. 2. Biogenic corrosion and hydrogen sulphide In large, partially filled gravity sewers, sulphate-reducing bacteria thrive under anaerobic conditions. The hydrogen sulphide (H₂S) they produce…
Wastewater DNA Shows Which Sewer Is Corroding
…part in sewer corrosion. In oxygen-poor wastewater, sulphate-reducing bacteria produce hydrogen sulphide; the researchers describe their role in sewer sulphide production as well established. Bacteria that oxidise sulphur compounds settle on the upper part…
Europe's Biomethane Matching Round Opens on 4 November
…rounds show Two other mechanisms on the platform have completed a first round. The hydrogen round drew 265 supply projects and 45 offtake projects. Of the supply offers, 87% received at least one expression of interest and 50% at least three, and 54%…
The New W4 Magazine Is Here
…old site were really article series. Each now has its own series page: the parts of the Hydrogen, Micro- and Nanoplastics, Europe at Risk and World Water Day series can be read together and in order, and every article shows which part of a series it is. The…
Europe Is Drying Up
…are consuming available water resources ever faster, and the spread of green hydrogen production could require further significant volumes of high-purity water – while wastewater reuse in Europe currently accounts for only 2.4% of water…
Drinking Water From the Sea, Without Brine or Chemicals
…lithium from the other salts (Tang et al., 2026b). The key to the method is that hydrogen titanate nanoparticles were embedded in the microscopic grooves of the metal surface; they selectively bind lithium ions while letting other minerals pass. In an…
Microplastics in Hungarian Tap Water: How Bad Is It?
…through a mesh of 500 μm or finer, followed by density separation (NaCl or ZnCl₂), hydrogen peroxide digestion to remove organic matter and, finally, FTIR or Raman spectroscopy or Py-GC/MS mass spectrometry to identify the polymer type. In Hungary, the…
Activated Carbon Against PFAS
…(about 0.004%) was detected. The likely reason is the formation of highly reactive hydrogen fluoride (HF), which reacts with the walls of the equipment (forming silicon fluorides) or with calcium in the carbon (CaF₂). Conclusion and environmental…
