2. Oxy-fuel combustion process - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_combustion_process

   However, oxy-fuel is a viable alternative to removing CO 2 from the flue gas from a conventional air-fired fossil fuel plant. However, an oxygen concentrator might be able to help, as it simply removes nitrogen. In industries other than power generation, oxy-fuel combustion can be competitive due to higher sensible heat availability. Oxy-fuel ...

3. Staged combustion cycle - Wikipedia

   en.wikipedia.org/wiki/Staged_combustion_cycle

   The fuel turbopump is driven by the fuel-rich preburner, and the oxidizer turbopump is driven by the oxidizer-rich preburner. [ 6 ] [ 5 ] Benefits of the full-flow staged combustion cycle include turbines that run cooler and at lower pressure, due to increased mass flow, leading to a longer engine life and higher reliability.

4. Oxygen reduction reaction - Wikipedia

   en.wikipedia.org/wiki/Oxygen_reduction_reaction

   Rather than combustion, organisms rely on elaborate sequences of electron-transfer reactions, often coupled to proton transfer. The direct reaction of O 2 with fuel is precluded by the oxygen reduction reaction, which produces water and adenosine triphosphate. Cytochrome c oxidase affects the oxygen reduction reaction by binding O 2 in a heme ...

5. Liquid-propellant rocket - Wikipedia

   en.wikipedia.org/wiki/Liquid-propellant_rocket

   One of the most efficient mixtures, oxygen and hydrogen, suffers from the extremely low temperatures required for storing liquid hydrogen (around 20 K or −253.2 °C or −423.7 °F) and very low fuel density (70 kg/m 3 or 4.4 lb/cu ft, compared to RP-1 at 820 kg/m 3 or 51 lb/cu ft), necessitating large tanks that must also be lightweight and ...

6. What is Flex Fuel? The pros and cons of flexible fuel vehicles

   Specially equipped vehicles designated as Flex Fuel capable can run on E85, a mix that's as high as 85% ethanol and just 15% gasoline. But, nearly all cars are already using a gasoline-ethanol mix.

7. Regenerative fuel cell - Wikipedia

   en.wikipedia.org/wiki/Regenerative_fuel_cell

   One example of RFC is solid oxide regenerative fuel cell. Solid oxide fuel cell operates at high temperatures with high fuel-to-electricity conversion ratios and it is a good candidate for high temperature electrolysis. [7] Less electricity is required for electrolysis process in solid oxide regenerative fuel cells (SORFC) due to high temperature.

8. Solid oxide fuel cell - Wikipedia

   en.wikipedia.org/wiki/Solid_oxide_fuel_cell

   Electrochemically speaking, the anode's job is to use the oxygen ions that diffuse through the electrolyte to oxidize the hydrogen fuel. The oxidation reaction between the oxygen ions and the hydrogen produces heat as well as water and electricity. If the fuel is a light hydrocarbon, for example, methane, another function of the anode is to act ...

9. Direct carbon fuel cell - Wikipedia

   en.wikipedia.org/wiki/Direct_carbon_fuel_cell

   A Direct Carbon Fuel Cell (DCFC) is a fuel cell that uses a carbon rich material as a fuel such as bio-mass [1] or coal. [2] The cell produces energy by combining carbon and oxygen, which releases carbon dioxide as a by-product. [3] It is also called coal fuel cells (CFCs), carbon-air fuel cells (CAFCs), direct carbon/coal fuel cells (DCFCs ...
