Rodney John Allam, MBE is a British chemical engineer and fellow of the Institution of Chemical Engineers who is credited with inventions related to power generation, notably the Allam power cycle, which is a generation process for fossil fuels, with integrated carbon dioxide capture.
Allam was employed by Air Products & Chemicals for 44 years, most recently as Director of Technology Development. In 2004, he was appointed member of the Order of the British Empire for services to the environment. He has also been a visiting professor at the Imperial College of Science and Technology and a lead author of the IPCC special report on carbon dioxide capture and storage, released in 2005. In 2007, the IPCC, along with Al Gore, was awarded with the Nobel Peace Prize.
His work has included new processes and equipment for production of gases and cryogenic liquids, such as oxygen, nitrogen, argon, carbon monoxide, carbon dioxide, hydrogen and helium. Several of these gases are generally produced through air separation, which is also a necessary step in the practical application of the Allam cycle, in which gaseous fossil fuels, for example natural gas or gasified coal, are combusted with pure oxygen. A 50 MW demonstration plant being built in Texas is expected to start operating in 2017.
