A low-cost coating system designed to optimize water electrolysis

Seemingly small component changes can make a large impact on the productivity of electrochemistry systems, such as electrolyzers used for producing “green” hydrogen. For example, a new coating technology developed by Oxford nanoSystems Ltd. (OnS; Abingdon, U.K.; www.oxfordnanosystems.com), when applied…

Recyclable wind turbine blades

As wind energy takes a prominent role in the energy transition, researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL: www.nrel.gov) have focused on manufacturing sustainable turbine blades that can be made from bio-derivable resources and then…

Process for continuous production of MOFs plans scaleup

Metal-organic frameworks (MOFs) have shown great potential for a number of applications, including as carbon-capture materials, but their use commercially has been limited by production methods, which are generally expensive batch processes. With the development of a continuous process for…

Recycling mixed medical waste with steam cracking

Currently, medical waste streams are complicated to recycle because these single-use products — such as facemasks, syringes, nitrile gloves and non-woven gowns — consist of multiple materials and must be considered contaminated with potentially infectious particles. Now, researchers at Chalmers…

Comprehensive destruction of airborne contaminants in a compact bioreactor

There are many categories of air contaminants that may be encountered in industry, from volatile organic compounds to aerosols to viruses, as well as a range of particulate matter and ultra-fine particles, which also vary greatly in size and properties.…

Two-dimensional template increases stability of perovskite photovoltaics

Using halide perovskites for photovoltaic (PV) solar-energy cells could dramatically reduce production costs compared to silicon-based PV cells, because perovskites are solution-processible at relatively low temperatures. However, long-term stability of these materials has been a significant challenge. Now, a research…

This electrolysis reactor requires no external electricity source

Electrolyzers are the key technology for producing “green” hydrogen using renewable energy. However, a new reactor platform aims to facilitate electrolysis without the need for any external electricity. The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO), developed by Utility…

Methane pyrolysis catalyst Catalytic methane pyrolysis (CMP) is an attractive route to producing hydrogen, because rather than generating CO2, the process produces solid carbon, which can be made in valuable forms that could offset the cost of hydrogen production. However,…

This integrated technology effectively destroys PFAS — even short-chain compounds

The prevalence of the various per- and polyfluoroalkyl substances (PFAS) — compounds that are notoriously difficult to break down — in the water supply is causing global concern. A new partnership between Element Six (Oxford, U.K.; www.e6.com) and Lummus Technology…

Recycling process allows fast depolymerization of post-consumer mixed textiles

Recycling rates for post-consumer textile waste are very low (<0.5%) because the fabrics often consist of tightly interlaced synthetic and natural fibers that require costly sorting and separation processes, and because they often contain dyes and additives that must be…
