An experimental gas turbine simulator equipped with an ultralow-emissions combustion technology called LSI, has been tested successfully using pure hydrogen as a fuel.

The milestone development indicates the potential to help eliminate millions of tons of CO2 and thousands of tons of Nox from power plants each year.

The LSI (low-swirl injector) technology recently won a 2007 R&D 100 award from R&D magazine, as one of the top new technologies of the year and was developed by Robert Cheng of the US Department of Energy's Lawrence Berkeley National Laboratory.

Cheng, who notes that these electricity generating turbines are similar in their operating principle to turbines that propel jet planes, commented, $quot;This is a kind of rocket science. The LSI principle defies conventional approaches.$quot;

Holding great promise for its near-zero emissions of nitrogen oxides, one of the more significant benefits of the LSI technology is its ability to burn a variety of different fuels from natural gas to hydrogen and the relative ease to incorporate it into current gas turbine designs.

The Department of Energy's Office of Electricity Delivery and Energy Reliability initially funded the development of technology for use in industrial gas turbines for on-site electricity production.
