The individual technologies that in combination make up this concept are all proven at scale in different industrial applications around the world, and the proposal now is to combine them on an industrial scale as part of a fully integrated system for low carbon power generation.
Another reason that projects such as these are now being actively encouraged is the increasing recognition that CO2 emissions contribute to climate change and that they need to be reduced substantially to help avoid dangerous impacts of climate change.
Each component of hydrogen power technology is proven and in use today. Hydrogen itself is in common usage in a variety of applications, including in oil refining for the formulation of clean fuels. Gasification technologies have been in use for many years, and integrated combined cycle turbines are currently used in natural gas power generation throughout southern California and the world. Gas pipelines and underground storage are in widespread use. CO2 already is transported by pipelines that are similar to other gas and liquid pipelines located throughout southern California.
