A significant part of the costs of popular  polymer electrolyte membrane (PEM) electrolysers is the cost of the rare metals required, such as iridium, platinum or gold.Korean researchers have discovered they can uniformly coat the electrode with iron oxide, which has low electrical conductivity, and then convert the iron oxide to iron nitride to increase its conductivity. Then they coat the iron oxide with a very thin layer of iridium, using about 10% of iridium currently used in PEM technology. This will significantly reduce the cost of the electrolyser, while apparently maintaining a similar performance.https://interestingengineering.com/innovation/boosting-green-hydrogen-korean-researc

Australian company Hysata  reports that its “capillary-fed electrolysis” (CFE) cell technology completely eliminates bubbles – one of the biggest remaining drags on electrolyser efficiency – making it the highest performing cell globally. Typical efficiency levels are currently around 75%. The Hysata team are reporting their system can deliver overall efficiency levels of 95% - making hydrogen production of below US$1.50/kg per kilogram by the mid-2020s more achievable.https://hysata.com/news/hysata-delivers-the-step-change-needed-in-electrolysis/

Write the World notebooks has raised more than $114,000 for charities tackling global poverty. Created by a family who wanted to do more, they fund the notebooks themselves – all with different designs by prominent artists. “We produce gorgeous notebooks and sell them online to raise money to tackle issues around global poverty. Every $10 notebook purchased becomes a $10 donation to one of The Life You Can Save’s recommended charities,” says founder Kate Tapping.The Life You Can Save makes smart giving simple by "recommending charities that save lives and improve well-being where each dollar goes the furthest."https://www.writetheworldnotebooks.org
