GloSho'14: Accessing the Water and Energy Markets of California - Jeff Reed
The document discusses how Southern California Gas Company and California are working to meet emissions challenges. It summarizes that California aims to reduce greenhouse gas emissions by over 80% and reduce nitrogen oxide emissions from combustion by 75-90% over the next 20 years. It states that technology advances in efficiency, optimized combustion systems, carbon-neutral fuels, and emerging applications can help meet these goals. Specific examples discussed include natural gas vehicles that can reduce nitrogen oxide by 80% and greenhouse gases by 50%, natural gas distributed generation that offers near-zero nitrogen oxide and 20-50% less greenhouse gases, and power-to-gas demonstration projects in Europe converting excess renewable electricity to hydrogen and synthetic methane.
