Hydrogen: Technologies, Policies and Challenges Zhang Jun1, a* Ji Lucheng2, b Jin Bo1, c 1Department of Energy Information Research, Wuhan Documentation and Information Center of Chinese Academy of Sciences, China 2School of Aerospace Engineering, Beijing Institute of Technology, China azhangjun@mail.whlib.ac.cn, bjilc@bit.edu.cn, cjinb@mail.whlib.ac.cn Corresponding author: zhangjun@mail.whlib.ac.cn, +86 27 87314525 Keywords: hydrogen, hydrogen economy, fuel cell, r&d, policy, technology Abstract.
From the perspective of United States’ technological funding decision-making mechanism, this was not solely Obama’s individual will, but also results from the prospect analysis of engineering and scale applications of hydrogen energy technologies and the review of the hydrogen economy.
In the National Medium and Long Term Program for Science and Technology Development (2006-2020) and the Energy Development Eleventh Five-Year Plan, the hydrogen energy is emphasized as one of the key advanced technologies.
Challenges for Hydrogen Economy Hydrogen energy has its advantages, but there are also many big challenges in science, engineering, economy and politics.

Introduction Defect engineering has a widespread and sophisticated application in the fabrication of microelectronic devices.
Entering nanoscale, however, changes the concept of defect engineering dramatically.
This indicates that defect engineering moves to single atom treatments and a consequent transition to single electron transistors including the employment of quantum mechanical properties associated to the wave behavior of single excess carriers [2].
