(English) Known as the Allam-Fetvedt Cycle, it is the process of transforming gaseous fuels to thermal energy while simultaneously capturing all emissions that include carbon dioxide and water.

• Allam cycle goes through a series of steps to achieve valuable byproducts and eliminate carbon related liabilities.  Oxy-combustion is conducted which consumes less amounts of fuel and increases temperatures and efficiency. This causes CO2 pressures to increase and eventually expand as it moves into a turbine and enters a heat exchanger. Water is then removed and a portion of the pressured carbon dioxide is compressed and captured inherently. As for most of the high pressured CO2, It is pumped back into the combustor where it is  reheated in order to repeat the cycle again.
• What is the Supercritical CO2 working fluid? It s a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure.
• What is the Oxy-combustion? It is the process of burning natural gas with pure oxygen (instead of air). The Allam Cycle takes a novel approach to reducing emissions by employing oxy-combustion and a high-pressure supercritical CO2 working fluid in a highly recuperated cycle. The CO2 that must be  vented  from  the  process  leaves  at  pipeline  pressure and  high  quality  as  a  result  of  the  operating  conditions of the cycle, thereby mitigating the common necessity of an additional capture, clean-up, and compression system.
