THE CHEMICAL PROCESS
Energy and Mass Balance:
Using glucose as a representative SUBSTRATE:
C6H12O6 + 6 H2O = 12 H2 + 6 CO2
180 lb + 108 lb = 24 lb 264 lb
The stoichometric co-efficient; the volumetric ratio of Hydrogen to CO2 2 to 1.
The reactor gas contain 60 –70 volume percent Hydrogen.
Heat of combustion of Hydrogen 60,195 BTU/lb of Hydrogen.
Hydrogen energy yield = 24 x 60,195/180 = 8,026 BTU/lb of glucose.
Yield of methane from anaerobic digestion:
C6H12O6 = 3CH4 + 3 CO2
180 lb= 48 lb + 132 lb
Heat of combustion of Methane = 23,875 BTU/lb of Methane
Methane energy yield = 48 x 23,875/180 = 6,367 BTU/lb of Glucose.
Hydrogen production compares favorably with Methane production with a [ 8,026 x 100/6,367-
100] = 26 percent increase

WHE TECHNOLOGYAND THE
India with a population of 1.2 billion and a potential of 2.0 billion by 2020, collects and
treats less than 10% of the sewage produced.
India’s rivers, coastal waters and the ground water is getting polluted day by day.
Installing arteries for sewage collection, and installing sewage treatment plants to
manage all sewage presents an enormous cost burden.
The WHE technology with the potential of hydrogen production is a revenue earner
and shall incentivize sewage collection and treatment.
Hydrogen is a very clean fuel which produces only water as an end product .The CO2
produced can also be marketed.
THE ECONOMICS OF THE WHE
Three distinct cost centers in a STP benefit from the WHE process-
(1) Revenues from the sale of hydrogen
(2) Reduction of digested sludge volume by 40% lowering handling costs.
(3) Reduction in digestion period to 9-10 days from 21-30 days enhanced plant capacity.
The cost of just producing hydrogen-rich digester gas ( 70% by
volume) is US $ 2.82 per kilogram.
Alternative sources of hydrogen
(a) Electrolysis of water distributed scale.
(b) Natural Gas reforming process-cost. *
(1) Both above processes are subject to price escalations with increase in electricity
price and cost of natural gas. These factor do not impact the WHE process.
(2) They are not a renewable energy source.
ECONOMICS OF THE WHE TECHNOLOGY
• EPA-USA the average sludge volume is estimated at 169*
gallons per day (gpd) per person.
• A City like Delhi with a population of 18 million can produce waste water of 3.04 billion
gallons per day.
• This amounts to digested sludge of = 3.04 x .0031 = 9.43million gpd.
• Hydrogen production capacity =9,430,000/400 = 23,576 Kg./day.
• Gross sales revenue @ $ 8.00/Kg. = US $ 188, 608/day
• Cost of production @ $ 2.82/Kg. = US $ 51,676.50/day
• Gross profit per day = US $ 137,032/day
• Gross profit per year = US $ 41,109,600/year
• The earning potential is hypothetical and based on mobilization of resource, and treatment of
of all sewage.

ECONOMIC BENEFITS TO INDIA
India is emerging as one of the largest economic powers in the world. India can be the first
country to demonstrate the production of clean hydrogen from biomass on a commercial
India has used bio-mass as a energy source for centuries. This is the first intelligent and
smart conversion of digested sludge to hydrogen fuel. .
India’s sewage collection and treatment will improve dramatically with the STP’s turning
Hydrogen powered vehicles travel three times the distance compared to equivalent amount
of petroleum consumption.
The recognition of the intrinsic value of bio-mass to produce hydrogen and energy will create
an awareness for the preservation and collection of waste materials.
The awareness will stretch to urban and rural areas of the country for better collection
efficiency of industrial, chemical, domestic and agro wastes.
With full application of the technology and the collection and treatment of all biomass can
represent billions of dollars in earnings from the Smart Sewage Treatment Plants.
