The Advanced Hydrogasification Process (AHP) is being developed at Arizona Public Service (APS) to utilize the America’s abundant western coal supply to address concerns of diminishing domestic oil and natural gas resources as energy providers, while also incorporating a renewable energy and reducing greenhouse gas emissions. The AHP utilizes coal as a source for carbon, and hydrogen produced by renewable energy in the hydrogasification process to produce substitute natural gas (SNG) that can be fed to existing natural gas pipeline. The hydrogen will be produced through water electrolysis using wind firmed with off peak nuclear/coal electricity. The CO2 produced from the process will be recycled through biological approach — algae farming. With water and sun, algae will convert CO2 into starch, protein and lipids by photosynthesis.
