Splitting water molecules into oxygen & hydrogen has long been done by electrolysis. However, industrial electrolyzers are energy-intensive. So, inspired by photosynthesis, researchers have developed specially engineered electrodes that split water molecules when directly under the sun's light. This is a process known as photocatalysis.https://www.sciencedaily.com/releases/2021/01/210121131752.htm
The World Economic Forum estimates the world needs a 35% increase in the production of batteries by 2030 to meet the 2°C goal of the Paris Agreement. Attracting this level of investment is challenging enough, but consider also the additional problems of ethical mineral sourcing, the re-use and recycling of batteries, as well as the inevitable final life treatment of residual waste.The Global Battery Alliance takes a holistic view of the value chain & seeks to influence Government's, businesses & NGO's to support 10 actions to deliver a more sustainable value-chain for the electrification of transport.http://www3.weforum.org/docs/WEF_A_Vision_for_a_Sustainable_Battery_Value_Chain_in_2030_Report.pdf
Mallorca is a Spanish island known for its sun, coastline, architecture, wineries, fresh produce farms, and stunning beaches. It is also aspiring to be a self-sufficient green island or perhaps a Green Hysland. In their latest bid to reducing the island's emissions Acciona, Enagas, Hydrogenics, Cemex, the Government's Instituto para la Diversificacion y Ahorro de la Energia (IDAE) are collaborating on a green hydrogen pilot. Once operating it should produce up to 330 tonnes of green hydrogen (via solar power) for industrial energy needs. Any excess could potentially be injected into the gas grid. https://renews.biz/65509/acciona-partners-on-mallorca-green-hydrogen-scheme/
No-one wants an unstable electricity grid. With more renewables coming on-line every day, system strength and stability relies in part on effective management of inertia.Reactive Technologies have developed a data measurement & analytics tool which provides real-time tracking of grid inertia at a previously unavailable level of granularity and precision.This in turn supports more immediate, targeted and cheaper, system interventions to stabilise the grid. https://www.reactive-technologies.com/grids/
