HighEfficiency, LowEmissions Coal Plants: Come HELE or High Water GE

IGCC. Integrated gasification combined cycle (IGCC) is a technology that uses a highpressure gasifier to convert coal or other carbonbased fuels into pressurized gas. The synthesis gas (syngas), a mixture of carbon monoxide, carbon dioxide, and hydrogen, can be used to drive a combined cycle turbine, a cleaner way of burning coal.

An Experimental Study on Coal Fines Migration during Single Phase Water ...

Coal fines migration and intrusion in coal fractures affect coalbed methane (CBM) wells performance by reducing reservoir permeability and production continuity. Physical simulations are conducted to investigate the permeability variation under different diameter coal fines intrusion at various flow velocities and confining pressures. The results show that the conductivity of fractures is ...

Hydrogen Production Processes | Department of Energy

Hydrogen can be produced using a number of different processes. Thermochemical processes use heat and chemical reactions to release hydrogen from organic materials, such as fossil fuels and biomass, or from materials like water. Water (H 2 O) can also be split into hydrogen (H 2) and oxygen (O 2) using electrolysis or solar energy.

Frontiers | Sustainable Ammonia Production Processes

Due to the important role of ammonia as a fertilizer in the agricultural industry and its promising prospects as an energy carrier, many studies have recently attempted to find the most environmentally benign, energy efficient, and economically viable production process for ammonia synthesis. The most commonly utilized ammonia production method is the HaberBosch process. The downside to this ...

Underground Coal Gasification |

Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the Obviously ...
