Uni of New South Wales materials scientist
Professor Veena Sahajwalla has been named the New South Wales Australian
of the Year in recognition of her innovative research into recycling and green
manufacturing. She is best known for her invention of Polymer
Injection Technology, or ‘Green Steel’. Prof Sahajwalla has pioneered the transformation of waste to new green materials and products.
These include green ceramics made from recycled glass and textiles,
3D printing filaments from plastics salvaged from ewaste, and acoustic
panels made from coffee grounds.https://www.innovationaus.com/unsw-green-steel-inventor-named-nsw-australian-of-the-year/?
Blending green hydrogen into existing natural gas infrastructure has national benefits for energy storage, resiliency & emissions reductions. But if you actually need to separate the gases again at the end-user's site, this can be expensive. Researchers all over the globe are racing to find a solution. The Fraunhofer Institute has recently announced the development of a membrane & filtration process which can separate the hydrogen out at a 90% purity level - suitable for steel making. Not commercial or even scaled yet, but potentially a front-runner in the race to find a solution. https://innovationorigins.com/green-hydrogen-and-natural-gas-via-the-same-gas-network/
