Highview Power Storage. Energy storage through cryogenic fluids.

October 5, 2012 in Energy Storage

Highview Power Storage is a London-based startup developing a frozen air (or “liquid air”) technology for grid-scale storage applications. Many interesting grid-scale storage technologies have cropped up in recent years including liquid batteries, compressed air storage, storage through electric vehicles, lithion ion – and the need is clear: if we want successful integration of intermittent renewables (ie. solar, […]

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. […]

SolarFuel. Smart Energy Conversion.

March 23, 2012 in Energy Storage, Solar, Transportation, Wind

SolarFuel, a Stuttgart, Germany-based startup, is developing a Power-to-Gas (P2G) technology which converts wind and solar-generated electricity  into “storable” synthetic CO2-neutral natural gas. The key challenge facing the successful integration of renewable sources (re. solar, wind) into grid infrastructure is intermittency. Renewable electricity is generated irregularly – when the sun is shining or the wind is […]

LightSail Energy. Regenerative Air Energy Storage.

February 27, 2012 in Energy Storage

LightSail Energy, headquartered in Berkeley, CA, is developing an innovative Compressed Air Energy Storage (CAES) system for grid-scale energy storage that is clean, economical, scalable, and most importantly, efficient. Co-Founder and Chief Science Officer Danielle Fong, 24, is a two-time dropout (first at age 12, she left middle school to go to college, then at […]

General Compression. Expanding clean power.

September 9, 2011 in Energy Storage

General Compression is a Newton, MA-based company that has developed a energy system that makes available “dispatachable wind” in order to face the challenge of intermittency that wind and many renewable energy sources face. They have developed the General Compression Advanced Energy Storage (CGAES) system that takes electricity produced by wind turbines and stores that […]
