NOVELTY - The portable apparatus comprises a unit to boil water (704) to generate steam, a high-pressure steam-biomass reformer (706) to react the biomass with the steam at high-pressure in absence of air to generate high-pressure carbon dioxide and hydrogen gas, a methanol carbon dioxide separator (708) to separate a portion of carbon dioxide gas from the high-pressure gas at high-pressure to generate high-pressure carbon dioxide-rich driver gas (99 wt.%) and hydrogen-rich fuel gas, a furnace to utilize the hydrogen-rich fuel gas to generate heat to drive the steam reformer, and a gas turbine.    USE - The portable apparatus is useful for extracting low carbon petroleum and for generating low carbon electricity from biomass and water.    ADVANTAGE - The portable self-contained apparatus ensures economic, energy efficient and rapid recovery of petroleum oil without the risk of major investments in large facilities, expensive pipelines and large gas plants, produces enhanced electricity with high production and without harmful greenhouse gas emissions, and allows easy transportation of oil well from field to field with minimal human supervision or labor.    DETAILED DESCRIPTION - The portable apparatus comprises a unit to boil water (704) to generate steam, a high-pressure steam-biomass reformer (706) to react the biomass with the steam at high-pressure in absence of air to generate high-pressure carbon dioxide and hydrogen gas, a methanol carbon dioxide separator (708) to separate a portion of carbon dioxide gas from the high-pressure gas at high-pressure to generate high-pressure carbon dioxide-rich driver gas (99 wt.%) and hydrogen-rich fuel gas, and a furnace to utilize the hydrogen-rich fuel gas to generate heat to drive the steam reformer, a gas turbine to utilize the hydrogen-rich fuel gas to generate low carbon electricity, a compressor (714) adapted to compress the carbon dioxide-rich driver gas to a pressure appropriate for injection into a petroleum reservoir to extract low carbon petroleum, a heat exchanger disposed between the boiler and the steam reformer adapted to exchange heat between the hot high-pressure gas exiting the steam reformer and the steam entering the steam reformer from the boiler, and a system to control an operation of the apparatus based on a market price of biomass, electricity and a crude petroleum. The electricity has less associated carbon dioxide emissions than electricity generated from combustion of natural gas. A condenser is disposed after the heat exchanger to condense cooled high-pressure gas entering the methanol carbon dioxide separator from the heat exchanger. The boiler operates at 150-250 degrees C. The steam reformer operates at a temperature of 850 degrees C, and a pressure of 5-30 bar. The methanol carbon dioxide separator operates in a temperature-swing cycle of -60 degrees C to -40 degrees C. An amount of carbon dioxide is released, when the petroleum is consumed less than the amount of carbon dioxide injected underground to extract the petroleum. The steam reformer is a fixed bed reformer, a fluidized bed reformer, and an entrained-flow reformer. The high-pressure, steam-biomass reformer is designed to carry out a steam-biomass reforming reaction with a chemical equation of CxHyOz+H2O to give xCO2+wH2, where CxHyOz represents biomass, H2O represents water, CO2 represents carbon dioxide, and H2 represents hydrogen, and the carbon dioxide concentration of x/(x+w) in the high pressure gas is 30 wt.%.
