The efforts to lift our power generation and\u00a0electrical grid\u00a0into the 21st<\/sup>\u00a0century is a multipronged effort. It needs a new generation mix of low-carbon sources that include\u00a0hydro,\u00a0renewables\u00a0and\u00a0nuclear, ways to\u00a0capture carbon\u00a0that don\u2019t cost a zillion dollars, and ways to make the grid smart.<\/h1>\n

But\u00a0battery\u00a0and storage technologies have had a hard time keeping up. And they are critical for any success in a carbon-constrained world that uses intermittent sources like solar and wind, or that worries about resilience in the face of natural disasters and malicious attempts at sabotage.<\/p>\n

\"\"This was pressed home this week by the Department of Energy\u2019s decision to build a multimillion dollar\u00a0electric grid research complex\u00a0at the\u00a0Pacific Northwest National Laboratory. And better, larger batteries are a main component of this research.<\/p>\n

Jud Virden, PNNL Associate Lab Director for energy and environment, noted that it took 40 years to get the current lithium-ion batteries to the current state of technology.<\/p>\n

It\u2019s not like we\u2019ve been idle. We just haven\u2019t been wildly successful. Battery technologies do keep getting better. Recently, Jack Goodenough, the inventor of the Li-ion battery, came out with a new\u00a0fast-charging battery technology\u00a0using that uses\u00a0a glass electrode\u00a0instead of a liquid one, sodium instead of lithium, and may have three times as much energy density as lithium-ion batteries.<\/p>\n

And in addition to batteries, we do have other technologies for storing intermittent energy, such\u00a0thermal energy storage,\u00a0 which allows cooling to be created at night and stored for use the next day during peak times.<\/p>\n

At present, the most widely used storage method is\u00a0pumped hydro storage, which uses surplus electricity to pump water up to a reservoir behind a dam. Later, when demand for energy is high, the stored water is released through turbines in the dam to generate electricity.<\/p>\n

Pumped hydro is used in 99% of grid storage today, but there are geologic and environmental constraints on where pumped hydro can be deployed.<\/p>\n

We\u2019ve even looked at other gravity-based energy storage systems, like\u00a0Advanced Rail Energy Storage, that uses surplus wind and solar energy to move millions of pounds of rock uphill in special electric rail cars that roll back downhill, converting this gravitational potential energy to electricity that goes out onto the grid.<\/p>\n

But we really need utility-scale chemical battery storage to deal with rapid intermittency in both generation (renewables) and demand (rapid changes in use throughout the commercial day). These need to be very large but very stable and long-lasting.<\/p>","protected":false},"excerpt":{"rendered":"
