Document Summary
But there are plentiful of coal (dirty fuel), how can we live in the future with coal, burn it differently. Carbon monoxide can further undergo water-gas shift reaction (oxidation reaction): Co+h2o (g) co2+h2: generating fuel-h2 that can be collected and generate electricity hydrogen economy . Instead of combusting in air, combustion with water forming pure co2 and hydrogen. Co2 and hydrogen can be easily separated due to their volatility: carbon monoxide and hydrogen are the feedstock for building up hydrocarbons. Fischer tropsch process :nco+(2n +1) h 2catalyst. Cn h 2n+2+n h 2 o: different catalyst produce different hydrocarbon, nickel: methane, cobalt: higher alkane. Hydrogen is a secondary energy source, and also a clean fuel. oxidized hydrogen: h 2+1. When you electrochemically convert hydrogen into water by fuel cell higher efficiency. Put fuel cells together, to give you enough voltage for car. However, batteries are very heavy, and have to carry hydrogen onboard.
