Biomass
IISc CGPL UNDP MNRE Biomass Gasifier Workshop, Feb 4-5 2013 @ IISc CGPL Slides, Presentations, etc at janastu.org/biomass
Minutes by Dinesh (needs cleanup)
srinivas UNDP (all material on website)
GEF - global env facility - a trust to address climate change devpd nations contribute funds to mitigate climate change and
related innovations
units:
Energy
solar concentrator for ..?
solar water heater
energy efficiency projects
typically with the govt
MNRE - tanushree is project manager
THIS project
- remove barriers for biomass biomass combustion (punjab gives Rs 5.50 can sustain)
large mega-watt biomass systems have failed as sourcing biomass
becomes an issue.
thus sub mega-watt and sub 2meg-watt range
associated with TERI and Univ of Dehradun (in North India)
Srinivas Murthy of KSCST
since 1975 the council is working on alt energy
mohan and prithviraj at international bio today
dasappa: many student projects are converted into products
Dasappa
fuel linkage problems for large scale bio-mass projects (eg andra pradesh)
ask for slides abets@cgpl.iisc.ernet.in IGFC - integrated gas..
1 lit of diesel by 3 to 4 kg of biomass biomass - great efficiency even at small scale (100Kw)
6000 hours of operation = successful
biomass atlas/calendar on what biomass is available when/where
srinivas: compendium of data on undp site
from mnre 1.5 crores per megawat subsidy
+ $50k in addition - tech assitance
(min 100 kw to max 2 megwatt)
for captive its less
rajan
converted surveys and regional reports into a digitized atlas
agro-residue forest based waste land
biomass (surplus) potential = 16000 MW
sheshagiri - biomass atlas
biomass resource atlas of india http://lab.cgpl.iisc.ernet.in/Atlas/

"in UP in karif and rabri season.. you can see a lot of paddy and
wheat is grown"
NDVI - normal derivative of vegetation index
ranganathan
story: manufacturing pens 5 yr ago came in contact with someone using US tech for sugar mills - where the mills did not have to invest anything. i tried to market it but sugar mills not impl interested. 20-25000 acres for 50MW plant. met Dr Rajan to know about biomass atlas. then i was introduced to gasification tech. we went to visit a plant in Coimbotore. got a 2nd hand gasifier for a good price. Gasifier running for 4 yrs now. 1.5 MW gasifier is Gadag going into operation soon. (why Gadag)
Bio-mass: round the clock energy resource
bio-char - new black gold
choose bamboo plantations
sustainable
bamboo clubs will remain for ever and every year you can harvest
no replanting
harvestable from 3yr
bambusa balcooa
30-40 tons per year per acres
20 liters per day per clum (drip irrigation)
melia dubia (where there is more water)
250 acres per megawatt
10 crore per MW investment
chandramouli
poly generation using biomass gasification
velan hotel - thriupur - knitting capitol $3billion turnover & mall in 20 acre area
(Acclaim technology services) also asphalt production (on slide)
MNRE has proposed a generation based subsidy
dinesh j kagathi - allgreen energy capacity 6MW at perundurai SIPCOT industrial estate, erode dist TN
300km from blore - commissioned by May 2013
process configuration and economics:
Independent Power Producer role (as investors)
GM backer(?) engines (better than Cumins etc)
IISc tech - flexibility of feed stock
Gas quality
activation chamber to make activated carbon - if fuel is coconut shell
REC (Rs 1.62 per KWh) - its a concern today
conclusion session
dasappa and srinivas:
gasifier tech developed with the hosahalli project 1987 can it become a sustainable solution converted grazing lands to forests initially people not enthused about electricity women folk bringing water
we dug a borewell and put up pump women made men sit and listen after that 65-75% collection efficiency
brought in economic activities
to generate enuf money to pay for services tumkur dist - near huliyurdurga
every kg of gas we generate 100ml of water
processed water which is scrubbed has
organics that pollute it and cannot be discharged into the fields
- biomass itself can have contaminants can will be scrubbed.
calorific value of all biomass is same on ash-free basis CHO + H2O + Ash GoI has allowed 30% coal use in biomass units
(some ppl misuse it to upto 100% and can be shut down)
ifomia (also called besharam which is not used for burning for cooking as when you burn you get flesh smell) - absorbs potasium from marshy lands
prabhakar
associated with largest powerplant in the field Coimbatore area Arrya high-tech energy 1MW biomass gasification grid connected power plant commissioned on jan 2005 plant has operated for over 40,000 hours area has abundant coconut shell thus the location coconut shell price (2002 price 750/ton then 1100/ton to 2600/ton) not viable suddenly mnre then released a subsidy of 1.2 crore 2nd case: For captive power for Beach Minerals company Pvt Ltd Kuttam Cummins India realized this is similar to natural gas and gave warranty
D L SubbuKrishna
env aspects gaseous emissions (no norms) and liquid emissions (liquid hydro
carbons and waste lube oil)
