Sadoway’s “dirt cheap” battery. A solution for grid-scale renewables?

May 24, 2012 in Energy Storage

Grid-scale adoption of renewables requires energy storage.  Cheap energy storage. For instance, the cost of PV solar, approaching $0.25/kWh, is becoming cost competitive with traditional baseload energy sources (gas, coal, nuclear, etc.), with production costs of about $0.05-$.015/kWh. But solar is intermittent.  And to become “baseload”, PV solar needs to be coupled with an electrical storage system. [...]

3-D Solar. Up to 20x more power than flat panels.

April 8, 2012 in Solar

Numerous companies – 1366, Bandgap, Twin Creeks, and more – are striving to optimize solar cell efficiency or manufacturing to bring down solar costs. Regardless of the innovative process, the end-result is generally the same: a flat panel that is fixed on a rooftop or other surface. A team of researchers at MIT is considering [...]
