MIT battery that inhales and exhales air can store power for months

Comments Off on MIT battery that inhales and exhales air can store power for months

Could this air-breathing battery help solve energy storage woes? 10 Massachusetts Institute of Technology (MIT) researchers developed the battery capable of storing electricity for months for around one fifth of the cost of comparable technologies. MIT professor Yet-Ming Chiang said, “This battery literally inhales and exhales air , but it doesn’t exhale carbon dioxide , like humans – it exhales oxygen .” MIT says their air-breathing battery could help renewable energy , like solar and wind, be more practicable for the grid . Their rechargeable flow battery costs a fraction of current technology, and can store power for long periods of time, with zero emissions and few location restraints. Related: Former Tesla executives to produce battery “with significantly lower carbon footprint” Sulfur dissolved in water comprises the battery’s liquid anode. What MIT described as an aerated liquid salt solution in the liquid cathode brings in and lets out oxygen. According to the institute, “Oxygen flowing into the cathode causes the anode to discharge electrons to an external circuit. Oxygen flowing out sends electrons back to the anode, recharging the battery.” The cost of the anode, cathode, and electrode materials in the battery is around 1/30 that of lithium-ion batteries , according to MIT. If the battery system was scaled up, it could store electricity for around $20 to $30 per kilowatt-hour – compare that against today’s batteries, which are around $100 per kilowatt-hour, at least. Right now, the prototype is about as big as a coffee cup. But Chiang said flow batteries are highly scalable. This new technology could compete with pumped hydroelectric storage systems, though, since the MIT system is more compact, it could be deployed in more locations where renewable energy is being generated. As solar and wind energy production can be intermittent, the battery could store the energy they generate to offer a reliable source of power. The journal Joule published the research this week.

Comments Off on Rethinking the Water Cycle for a Water Quality Constrained World

Global water scarcity is a function of the compounding impacts of decreasing availability and declining quality. The impacts of these factors on business are complex and far reaching. Succeeding in a water quality constrained world requires the ingenuity of business to drive water strategies that go beyond conservation to reuse, recycling and stewardship.  Ecolab vice president of sustainability Emilio Tenuta will outline imperatives for achieving business resilience  amidst water scarcity.

Can Re-greening the Planet Make Commercial Sense?

Comments Off on Can Re-greening the Planet Make Commercial Sense?

Natural systems – forests, grasslands, and wetlands – can deliver over a third of the mitigation needed to meet the Paris Agreement’s 2 °C target, a critical biological bridge in the next two decades. Growth in demand for natural resources will put unprecedented pressure on our planet, but it also brings opportunity for economic growth and value creation.
