The Administration’s Energy Plan has two goals that rely heavily on improvements in the science and technology of energy storage: Solar and wind providing over 25% of electricity consumed in the U.S. by 2025 1 million all-electric/plug-in hybrid vehicles on the road by 2015
Batteries and Energy StorageCross-Cutting Challenge that Impacts Energy Technologies
• Grid stability and distributed power require innovative energy storage devices– Grid integration of intermittent energy
sources such as wind and solar– Storage of large amounts of power– Delivery of significant power rapidly
• Enabling widespread utilization of hybrid and all-electric vehicles requires:– Substantially higher energy and
power densities – Lower costs – Faster recharge times

Batteries and Energy Storage Hub Transform the Grid and Electrify Transportation
16
Improved energy storage is critical for the widespread use of intermittent renewable energy, electric vehicles, and efficient and reliable smart electric grid technologies.
The Hub, proposed for FY 2012, will develop electrochemical energy storage systems that safely approach theoretical energy and power densities with very high cycle life.
These are systemic challenges requiring new materials, systems, and knowledge.
The Hub will address key fundamental questions in energy storage including:
Can we approach theoretical energy density? Can we safely increase the rate of energy utilization? Can we create a reversible system with minimal energy loss?
The Hub will link fundamental science, technology, and end-users, and it will collaborate with relevant Energy Frontier Research Centers, ARPA-E and EERE
• Move science and technology for electrochemical energy storage forward at a rapid pace to enable transformative developments for reliable energy supply and transportation systems
• Provide a strong linkage between fundamental science, applied technology and end-use communities to create long- and short-term innovations that would not otherwise be achieved
