Acenes are benzene molecules with unique optoelectronic properties. Singlet fission solar cells can produce two electrons from one photon, making the cell more efficient.
Massachusetts Institute of Technology (MIT) scientists have developed a train-like concentrated solar power (CSP) system for hydrogen production, with plans to build a prototype in the coming year. They say that this innovative system can capture up to 40% of the sun’s heat to produce environmentally friendly hydrogen fuel.
Massachusetts-based Re:Build Manufacturing has unveiled the RBM600 Solar CZ Puller, a solar ingot processor designed to manufacture high-purity polysilicon ingots for solar panels.
Academics from MIT and Stanford who have posited a new production method for perovskite solar cells have also developed a machine learning system which benefits from the experience of seasoned workers – and they’ve posted it online for anyone to use.
Grasshopper, a Canada-based renewable energy developer, will use $48 million of financing to support four solar+storage projects in Massachusetts.
If the three record-busting low solar price tariffs recorded in the Middle East in the past 18 months are to be believed, renewables-powered hydrogen in prime sites in the region could already compete with gas-plus-CCS production, according to IRENA. Has the Gulf discovered the new petrol?
David Riester of Lacuna Sustainable Investments, looks at how, on the journey from concept to monetized power plant, renewables and energy storage projects tend to get tugged toward ‘zero’ margin, from either direction. The further the rubber band is stretched, the stronger the pull back toward zero.
Scientists led by MIT have suggested chitin, a carbon and nitrogen-rich material made from waste shrimp shells, could produce sustainable electrodes for vanadium redox flow batteries and other energy storage technologies.
MIT scientists have suggested used electric vehicle batteries could offer a more viable business case than purpose-built systems for the storage of grid scale solar power in California. Such ‘second life’ EV batteries, may cost only 60% of their original purchase price to deploy and can be effectively aggregated for industrial scale storage even if they have declined to 80% of their original capacity.
