- We wrote about this innovative grid project months ago that now has added an important element- new powerful batteries that aim to solve the barrier that renewable energies of solar and wind have by storing the energy so it can be used when there is demand, not just when it is created. Exciting! If you have investment capability, there are opportunities here. - Editor
The startups that have teamed up to build a transmission hub to connect the U.S.’s three major grids in the east, west and Texas are adding another startup player for energy storage. This afternoon, Tres Amigas, the Santa Fe, N.M-based company behind the transmission project, announced that they have partnered with Xtreme Power, a startup which provides groups of batteries for energy storage for the power grid. Xtreme Power’s batteries would provide storage for the SuperStation to help balance the flow of electricity, and importantly, to enable the addition of more clean power, which is variable, depending on the wind and sunlight, which aren’t always available. Xtreme Power’s batteries would store and release power in response to fluctuations in demand and supply at the hub. For its batteries, Xtreme uses a PowerCell battery chemistry that it calls a “chemical capacitor,” which it says can beat lithium-ion batteries in terms of energy storage, efficiency, cycle life and cost. CEO Carlos Coe told us that Xtreme’s PowerCell battery tech acts more like capacitors: charging and discharging at high speeds, while at the same time, maintaining the qualities that make batteries better than capacitors for long-term energy storage.
