There is a role for both pre-combustion and post-combustion technologies in reducing CO2 emissions from power generation facilities. HECA’s new pre-combustion facility is a significant step in making new power generation facilities able to produce reliable low carbon electricity.

Are the technologies proposed for the HECA facility proven?
The HECA facility will be using existing proven technologies but will be the first operation in the world that groups them together in one plant to perform commercial scale carbon capture storage during power generation.
Gasification: Gasification technology has been used for decades and its uses range from gasification for chemicals production and products to power generation. Primary technology providers for the gasification of coal and petroleum coke feeds in conjunction with combined cycle power generation are GE, ConocoPhillips, and Shell.
Gas separation: Gas separation (in this case CO2 capture) is widely used and is a standard technology across the oil and gas industry. LNG liquefaction plants commonly have CO2 capture facilities to extract CO2 from the gas stream before liquefaction. Refineries are another user of CO2 extraction/capture technology.
CO2 transport: This is a long-standing activity in the Permian basin of West Texas. CO2 is produced from naturally occurring reservoirs at Sheep Mountain and the Bravo dome, and has been safely transported (over 200 miles) and injected into Permian reservoirs for EOR. Occidental is a key player in both the transportation and injection of CO2.
CO2sequestration by reinjection: This process is currently conducted at the Sleipner field in Norwegian North Sea, and at In Salah in Algeria.
H2-fired turbines: Natural Gas fired turbines with operational properties similar to those needed for Hydrogen combustion have been used for years. All major turbine designers have effectively tested the combusiton of the Hydrogen in modified natural gas turbines.
