Power Shift: a Durham company seeks to change an industry – Durham Herald Sun

“with Allam’s cycle, the exhaust exits the turbine and goes into a heat exchanger, which then recycles the hot stream of carbon dioxide throughout the system, skipping the condensing process and keeping the system at a higher pressure and temperature to retain efficiency.

 

In 2009, Rodney Allam sat down with a four-function calculator and began to model an emissions-free power generation cycle.

Over the course of several months, he came out with pages of calculations and a crucial number, called net efficiency.

This number indicated Allam’s cycle was more efficient than existing power generating cycles, while at the same time, it captured 100 percent of carbon emissions.

Now, $140 million in investments later by some of the world’s largest energy firms, a 25-person Durham business hopes to upend the entire energy industry.
“It’s definitely a breakthrough,” said Joe Strakey, the now-retired chief technology officer for the U.S. Department of Energy’s National Energy Technology Laboratory.
