Develop Energy Efficient Superconductor Technologies
in Collaboration with American Industry and Universities
HTS Benefits are Widespread
Nation Facing Energy Crisis• US Economy Dependent on Energy
– Loss of Industries and Jobs • Projected Shortages in Oil & Natural Gas
– Exponential price increases in next 20 yrs– Increasing world wide demand
• Global warming related to carbon release• Aging Electric Power Transmission Grid• Need to Increase Efficiency & Capabilities

High-Temperature Superconductivity (HTS) is Pivotal to US Energy Sustainability
10% of electricity generated in the US each year (300 million kilowatt hours) is lost due to resistance of copper and aluminum wire
Superconductors, which have nearly zero resistance, can make most of that lost energy available with no additional fossil fuel use or generating capacity
The energy lost to electrical system inefficiencies could supply the combined energy needs of California, Oregon, Arizona, and New Mexico
Superconducting Magnetic Energy Storage (SMES) systems will improve infrastructure reliability by protecting against grid fluctuations
Superconducting Magnetic Energy Storage (SMES) systems will improve infrastructure reliability by protecting against grid fluctuations
Accelerated HTS Technology Development will Impact the US Significantly
Save $16B annually in US energy costs $11B in transmission losses
Rejuvenate the US power equipment industry $200B annual sales worldwide of HTS power equipment by
2020 Strengthen the reliability of the US electricity infrastructure Create 150,000+ new high-technology domestic jobs Improve medical, communications, and electronic equipment Improve systems for national security Eliminate hazardous materials from electrical systems
Superpowering the Electric Grid
• High Temperature Superconductors (HTS)– no electrical resistance (cooled with liq N2)– 1000 times current carrying capacity of copper– more powerful, efficient, smaller, lighter– Increased Energy Infrastructure Security

HTS Wires
IBAD MgO based coated conductor 5 thin oxide buffer layers with different functions
Substrate ~ 80nm alumina
Superconductor Stabilizer
~ 10nm IBAD MgO
~ 30nm STO~ 20-30nm Homo-epi MgO
~ 7nm yttria
Alumina --- barrier layer to prevent diffusion of metal element into superconductor
Yttria – seed layer to provide good nucleation surface for IBAD MgO
IBAD MgO – template layer introduce biaxial texture
Homo-epitaxial MgO --- buffer layer to improve biaxial texture
STO --- cap layer, to provide lattice match between MgO and YBCO and good chemical compatibility.
