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, […]

Pavegen. Renewable energy from footsteps.

August 6, 2012 in Distributed Power, Efficiency, Energy Storage, Random Cool

London-based Pavegen builds energy-harvesting tiles based on a hybrid piezoelectric technology that transform footsteps into electricity. The technology is featured at the London Olympics, where 12 tiles have been installed at the West Ham tube station connecting to the Olympic Park.  These tiles generate and store electricity (each has a small battery) in order to power […]

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 […]

Eos. Power the dawn of energy storage.

December 19, 2011 in Energy Storage

Eos, based in Easton, PA, is developing a game-changing low-cost, rechargeable zinc-air battery storage technology for utility and transportation applications. Unlike other high-tech storage technologies (re. lithium ion batteries as produced by A123), zinc-air batteries are made from non-toxic, non-flammable materials.  Moreover, zinc-air batteries demonstrate tremendous promise because they have a high energy storage capacity and […]

Better Place. Accelerating the transition to sustainable transportation.

November 21, 2011 in Efficiency, Energy Storage, Transportation

Better Place is developing a multi-faceted infrastructure to support and ease the expansion of the electric vehicle (EV) market. Better Place’s various solutions include: Batteries – Development of advanced lithium batteries through partnerships with storage companies like A123 Charging stations – Networks of “charge spots” in office and public spaces to provide convenient charging Battery switch […]

A123. Game changing energy storage solutions.

November 7, 2011 in Energy Storage

A123, an MIT spinoff with headquarters in Watertown, MA, produces advanced Nanophosphate® lithium ion batteries for transportation, grid, and commercial applications. A123’s core technology is designed to be longer-life, more efficient, more durable, and safer than existing generation batteries (lead-acid, sodium-sulfur, nickel-cadmium…). A123 products have already penetrated the electric vehicle (EV) market and expect to grow […]

EGG-energy. Building the Portable Grid.

October 28, 2011 in Appropriate Technology, Energy Storage

EGG-energy is a for-profit social enterprise, targeting the off-grid market in Tanzania to provide a battery subscription service.  As they put it, EGG-energy is the “netflix” of power. 86% of the population in Tanzania is not connected to the grid.  Ironically, of those 35 millions without electricity, 80% live within 5km of the grid.  EGG-energy’s netflix […]

OnChip Power. Bringing integration to power electronics.

September 20, 2011 in Energy Storage

If you travel or move around a lot with your laptop computer, I bet you often find yourself thinking twice about bringing your charger with you … because it’s just so cumbersome.  However, the end is near for clunky power supplies – thanks to OnChip Power! OnChip Power is an MIT spinoff that is working to […]

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 […]
