In the long run, there’s no avoiding energy storage for a 100% renewable energy society. The two major sources of renewable power are wind and sun, and they are either fickle or reliably not available at night. The problem is that the simplest energy storage option for electricity is batteries, … [continued]
Most electric cars, from the Tesla Model S to the Nissan Leaf, run on rechargeable lithium-ion batteries – a pricey technology that accounts for more than half of the vehicle’s total cost. One promising alternative is the lithium-sulfur battery, which can theoretically store five times more energy at a … [continued]
A Drexel University research team has developed energy storage technology that it believes can solve a vexing problem: how to cost-effectively store intermittent electrical energy from renewable sources at grid-level scale. The research team combined the concepts underlying flow, or redox, batteries used in electric vehicles (EVs) with those of … [continued]
“We saw millions of batteries were being scrapped every year, and set about researching how to take steps towards solving this problem,” says Williams. “What we found was the Nickel-Iron battery.” […]
Market research firm Lux Research is projecting that lithium-ion and molten-salt battery costs will get down to around $500/kWh by 2022. The bad news, if Lux Research is right, is that $500/kWh is twice the targeted $250/kWh. “Technology developers make bold claims about performance enhancements and economies of scale that will … [continued]
Rice University researchers have developed an unusual type of lithium-ion battery. It is a liquid that can be painted or sprayed onto any surface. The research team mixed various paints to determine which were best for the construction of the 5-layered components of a lithium-ion battery. Those components are: … [continued]
The number of energy storage projects deployed on a global basis is on the rise due to the onward growth of technology towards commercial availability. The total number of energy storage projects deployed and announced (including inactive projects) rose 8%, from 600 to 649 during the first half of … [continued]
The US Energy Information Agency (EIA) recently had a pretty interesting and useful post on electricity storage you might be interested in checking out. Here’s a nice graphic from the post, followed by the intro: “Electricity storage can be deployed throughout an electric power system—functioning as generation, transmission, distribution, … [continued]
Materials scientists at Harvard have demonstrated a solid-oxide fuel cell that converts hydrogen into electricity but that also stores electrochemical energy like a battery, allowing it to continue producing power for a short time after the original fuel source has been depleted. “This thin-film SOFC takes advantage of recent … [continued]
