Batteries can provide high levels of power but only for a short period. Biogas plants are mechanically inert but can store energy over longer periods of time. So what happens when you combine the two options on-site, say on a dairy farm? This is what German researchers Fraunhofer Institute for Energy Economics and Energy System Technology are trying to find out. Can't wait to hear more!
Aircraft looking "tidal kites" will generate electricity from the ocean's tidal power, as tested out at the Faroe Islands over the past year as they provide power to the islands.The technology has been developed by Swedish engineering firm Minesto, with larger versions of the tidal kites being rolled out in 2022.To find more, click the link:https://www.bbc.com/news/business-59401199
The paper industry is energy-intensive. According to the EIA, the industry consumed 1483.2 trillion British thermal units (Btu) of energy in 2019. At the same time, the CO2 emissions of the paper industry
reached 48 million tons. Utilising renewable energy is a well established way to try to reduce the emissions footprint of processing steps reliant on electricity. But replacing natural gas needed for high temperature drying is harder. In what could well be a world-first, a NZ company is replacing natural gas in its drying hood with geothermal steam instead. https://www.eeca.govt.nz/about/news-and-corporate/news/essitys-groundbreaking-geothermal-project-a-world-first/
Science Direct forecasts worldwide solar PV waste will to reach around 78 million tonnes by 2050. Recovery of materials such as silicon has traditionally needed hydrofluoric acid, a highly toxic and corrosive chemical. Scientists have found a new way to recover silicon which uses a specific chemical treatment sequence, using less toxic chemicals. The process delivers a silicon purity of 99.9984%, recovers more useful materials than just silicon and delivers a profit of $185 on every 1kg of solar panel recycled in this manner.https://www.saurenergy.com/solar-energy-news/indian-scientists-recover-pure-silicon-from-obsolete-solar-cells
