These hydrogen-ready turbines allowed the operators of the industrial plants to save millions of dollars on their supplies of natural gas . Hydrogen in Combined Cycles. All three designs are envisaged as hydrogen hybrids, which means they would be powered by gas-turbine engines that burn liquid hydrogen as fuel, and also generate electricity via hydrogen fuel. Hydrogen for energy transition. Hydrogen propulsion: Hydrogen can be combusted through modified gas-turbine engines or converted into electrical power that complements the gas turbine via fuel cells. RECONFIGURING BHGE'S NOVALT GAS TURBINE FOR 100% HYDROGEN DUTY. Using the molecular weights of each component, each gram of water would produce 0.11 grams of hydrogen and 0.89 grams of oxygen.
