Another area of research is new Hydrogen production methods, something he has been working with for 10 years. With Professor Armando Corripio and support from NASA and TDA he has been researching how to produce 95+% Hydrogen with the use of only a single reactor, a process that currently takes 3 vessels. Other groups in the US, Japan, and Norway are also incorporating his work into their research and in 2001 he was invited to the 4th Advanced Clean Coal International Symposium in Tokyo to lecture on this topic. For his work in this area, along with colleagues at Los Alamos National Laboratory, Dr. Harrison received one of 30 awards in 2001 from the Federal Laboratory Consortium for advancing "Technology in Service to Society."
