GE Looks To Battery Storage For Power Boost

Last week at the CERAWeek energy conference in Houston, Eric Gebhardt, vice president and strategic technology officer at GE Power, announced that the company would commit to building large-scale battery systems to store electricity in the next 10 years. The first product is a 1.2-megawatt lithium-ion battery that it expects to start delivering to customers in 2019.

Battery systems are integral to the large-scale implementation of alternative energies like wind and solar because the energy from solar and wind farms cannot be increased or decreased based on demand. Battery storage is necessary to give a bump to the electric grid during high demand periods. Battery technology has improved a great deal in recent years and General Electric “Reservoir” battery pack can, according to GE, last 15% longer than currently available batteries.

In recent years Lithium-ion batteries have come down in price and gone up in performance. However, the prevailing technology today is still not good enough to support massive electrical grid systems or manufacture electric vehicles reliable enough over long distances with enough battery charge to be useful to most of the population.

GE’s “Reservoir” is not new battery technology. It is a large box full of lithium-ion batteries. GE’s innovation comes in the form of a technology that regulates how energy is drawn from each of the batteries in order to maximize their duration.

The real test for GE will be whether the GE Power unit can produce truly revolutionary battery technology that will increase battery efficiency and decrease battery degradation by many orders of magnitude. Innovation on this scale – which may even mean abandoning the lithium-ion grail that so many in the battery storage business are committed to improving – would truly change the energy paradigm.

Large scale, effective and long-lasting batteries would cut pollution because we could rely more on renewables (solar, wind, hydro). We would be able to drive EV’s (especially if EV batteries improve) that truly minimize the environmental impact of transportation when they would be charged with power generated from non-polluting sources. We would be able to power data centers without polluting. We would be able to use petroleum for plastics and petrochemicals instead of power generation and transportation.
