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.
EV sales are set to be 1.7 million off because of the economic fallout of the Covid-19 crisis, however analyst BloombergNEF predicts that will be less of a hit than the anticipated fall in sales of conventional cars, increasing the penetration of electric models into the overall market.
Researchers in Australia have conducted a ‘cradle to grave’ life cycle assessment (LCA) of the four most widely used PV technologies. The academics say that cadmium telluride solar modules have the lowest life cycle impact, followed by amorphous, multi and monocrystalline silicon products.
That’s a significant feat for the country which has pledged to bring down the energy intensity of the economy by 33 to 35% compared to 2005 levels by 2030.
Developers have until June 30 to lodge bids to develop plots of solar capacity across the national rail network paying no more than Rs2.71/kWh for the electricity generated under a 25-year contract.
The renewables business of the conglomerate will undertake its first project across the border by providing engineering, procurement and construction services on a Rs12.6 crore, 3.1 MW array for a German-Bangladeshi knitwear company which will buy the power generated for Rs5.71518/kWh.
Demand for batteries is going nowhere but up, as new factories seem to appear almost every week with promises to power electric vehicles, consumer electronics, and grid-connected storage. But the lithium-ion technology that all of these rely on is not without drawbacks, and a whole host of new storage solutions is eager to get out of the laboratory.
The Climate Investment Platform launched by three multilateral bodies in September is now open for business and renewables companies in developing nations across 14 regions including south Asia could qualify for help with clean energy facilities, renewables-related grid improvements and energy efficiency schemes.
An growing number of companies globally have set sustainability targets to address the climate emergency. More than 700 companies are taking action to reduce their carbon footprint, write Caroline Zhu and Jiayin Song of Rocky Mountain Institute, and over 200 companies have publicly made the RE100 commitment to procure 100% of their electricity from renewable energy.
Scientists in India have tested a new inverter topology with a single-phase, induction-motor water pump. The seven-level inverter, with five power semiconductor switches, is said to be particularly efficient at reducing switching losses thanks to a pulse width modulation technique.
