  • Storage of intermittent renewable energy as fuel using carbon containing feedstock
    Patent number: 9249064
    Abstract: A method and system for converting intermittent renewable energy and renewable carbonaceous feedstock to non-intermittent renewable electrical and thermal energy, storing it as fuels and chemicals and using it to capture and re-use or dispose of CO2 emissions. The system in a preferred embodiment is realized through the generation of non-intermittent renewable electricity utilizing intermittent renewable energy sources along with gaseous fuel from renewable carbonaceous feedstock, producing oxygen and hydrogen from non-intermittent renewable electricity and utilizing the oxygen and hydrogen as required for gasification of renewable carbonaceous feedstock to produce gaseous fuel stream and gaseous intermediate stream, utilizing the gaseous intermediate stream to produce renewable fuels and renewable chemicals, and utilizing oxygen for oxy-rich combustion for concentrating CO2 emissions for easy processing, re-use and disposal.
