Researchers at the University of Warwick’s Warwick Process Technology Group have devised a process that turns wet waste from sewage farms and paper mills into a source of power.
University of Warwick researcher Dr Ashok Bhattacharya and his team are part of a Europe wide consortium that have cracked the problem of how to extract very pure levels of hydrogen from wet bio-matter, such as sewage or paper mill waste. This very pure hydrogen can then be used in “fuel cells” to power homes, factories and cars. The research consortium have now received £2.5million in European funding to work up their lab based solution into larger prototypes. Eventually the research team’s “plated membrane reactors” could be built as small industrial units, no bigger than a large room in some cases, and added directly to the sites of sewage plants or paper mills.
Previous attempts to extract pure hydrogen from bio-matter to power fuel cells have only met with limited success, even with dry material. The new process extracts very pure hydrogen from the more difficult but exceedingly abundant wet bio-matter and even makes a virtue of the water content of the material to generate even more pure hydrogen.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
