Widespread penetration of renewable energy and increasing demands on reliability/security of the electrical grid
require extensive advances in energy storage technologies that are modular and scalable (kW-MW). EaglePicher
Technologies, Inc. (EPT), a leading battery developer, is teaming with Pacific Northwest National Laboratory
(PNNL), a world leader in research and development in solid state electrochemistry and energy conversion
technologies. The new generation Na-beta batteries will be developed utilizing EPT’s formidable expertise in
systems design and manufacture, and PNNL’s extensive capability and experience in the development of planar
solid oxide fuel cells (SOFCs). The program will leverage the experience from both the successful demonstration
of a planar design cell.
Critical Need
Our national electric grid needs to
significantly improve its capacity for storing
electricity. The grid regularly generates
surplus electricity to ensure that demand can
constantly be met. This surplus of electricity
is wasted because the grid has little capacity
to store it. While current practices serve to
keep the lights on, renewable energy sources
are disadvantaged because they only provide
electricity when weather conditions are
optimal. Flexible, large-scale batteries would
create a stronger and more reliable storage
network for the electric grid and enable
renewable energy sources to contribute to
baseload power generation.
