Hydro-Electric Potential: Hydro-Electric Potential Details of projects under construction Ongoing and Planned Projects Possible to add 10,000 MW by 2015
Natural Gas: Natural Gas Fastest growing primary fuel, worldwide
Indian statistics (2004-05):
Consumption: andgt; 31 BCM/year
Primary uses:
Power 41%
Fertilizer 32%
Sponge Iron 4%
Other 23%
Growing needs for transportation (and some cooking)
Latent demand estimated as high as 80 BCM (depends on price, of course)
Natural Gas Pipelines: Natural Gas Pipelines Possible Gas Imports (Tongia andamp; Arunachalam, 1999)
Imports of Gas: Imports of Gas LNG growing (5+ million tons/annum), but prices remain high
1 ton LNG can power ~ 1 GW of power
1 BCM gas ~ .8 GW of power
thus, 20 BCM ~ 16,000 MW of gas power
Initial imports won’t necessarily add to elec. capacity
Will substitute naphtha in power plants and find other uses as well
More than half the fertilizer feedstock is gas
Industry has already claimed the bulk of current LNG supplies
Biomass : Biomass India predominantly agricultural country.
Annual production of agro-forest and processing residues: 350 million tons
Power generation potential andgt; 22,000 MW
Advantages:
Decentralized generation: close to rural load centers.
Technology reasonably well developed
Environmentally friendly: No net CO2 emissions
Biomass Conversion Technologies: Biomass Conversion Technologies Gasifier-reciprocating engine
Power plants of 5 kW – 100 kW possible
Diesel engine needs ~ 15%-20% for ignition
Cost of electricity is high
Gas engine can operate on 100% syngas
Overall efficiency ~ 20%
Largest gasifier 100 kW
Fluidized bed combustion boilers
Rice husk and bagasse
25%-30%
Power plants of 5 MW – 35 MW operating in various sugar mills
Producing electricity is sweeter than sugar !!
50 kW biomass gasifier power plant in Karnataka
Biomass for Decentralized Rural Power: Biomass for Decentralized Rural Power Electric power requirement of typical Indian village andlt; 100 kW
~ 75% is irrigation pumps
Presently these get virtually free, un-metered grid supply of poor quality, few hours a day
Locally available biomass can sustain a plant of 25 kW-100 kW
Gasifier-reciprocating engine technology is fairly robust
Cost of generation reasonable
$ 0.06-0.07 per kWh
BUT, still widespread dissemination not visible:
Economics unviable due to low PLF
People not willing to pay when state gives free !
Loss of organic fertilizer on land
