Cogeneration hydrogen

Hydrogen can be separated from the flue gas at low cost in high-temperature fuel cells. A SOFC system may be able to cogenerate hydrogen for about 3.00 per kg which can match gasoline. Since these fuel cells could be part of the fueling station, there would be no need for a hydrogen delivery infrastructure. 

A 2002 study for the National Energy Technology Laboratory found that coal gasification systems with C02 capture could reach efficiencies of 60% or more in cogenerating hydrogen and electricity using different configurations of turbines and solid oxide fuel cells (SOFCs). 

The primary intermediate (genetically referred to as the dianil), a 2,5-diarylamino-1,4-benzoquinone (5), where X = H or Cl or NHCOCH3, is obtained by the reaction of an appropriately substituted aromatic primary amine with a suitably functionalized quinone. An acid scavenger (e.g. sodium acetate) is included in any process utilizing a chlorinated quinone to neutralize the cogenerated hydrogen chloride, which otherwise would proportionately deplete the amine component.

However, if the major source of hydrogen is reformed natural gas, the cost of generating electricity with a low-temperature fuel cell would be about 0.20 per kilowatt-hour. This is more than double the average price for electricity. It would also produce 50% more carbon dioxide emissions than the most efficient natural gas plants which are combined cycle natural gas turbines. Low-temperature fuel cells operating on natural gas are not as efficient at generating electricity. A stationary fuel cell system achieves high efficiency by cogeneration. 

In 2003 the Department of Energy announced FutureGen, also known as the Integrated Sequestration and Hydrogen Research Initiative. This is a 10-year, billion dollar project to produce a 275-MW prototype plant that will cogenerate electricity and hydrogen and sequester 90% of the C02. 

The U.S. Department of Energy (DOE) has started the billion- dollar, FutureGen project to demonstrate a 275-megawatt prototype plant that cogenerates electric power and hydrogen and sequesters 90% of the C02. 

Therefore, it is anticipated that this initial project will lead to broader social and environmental advances and act as a model for further cogeneration plants. Conversion of hydro, wind and, solar energy to electricity and to hydrogen will open a new venue for the efficient utilization of renewable energy resources in Azerbaijan.
