Health impacts of solid fuel use Indoor air pollution due to the solid fuel use is causing 875,000 deaths annually in India Source: Global and Indian Burdens of Disease from Household Air Pollution the GBD study 2010

Indian Improved cook stove programme National Programme for Improved Cook stoves (NPIC) implemented from 1984-2002 National Biomass Cook stoves Initiative from 2009 present (ongoing) MNRE developed a PoA for CDM in biomass cook stoves and submitted to UNFCCC in 2012
Evolution od Indian standards for WBT As part of NPIC the Bureau of Indian Standards (BIS) developed a certification process for biomass cook stoves. The BIS protocol calls for using a set amount of fuel, based on stove heat production rate, and determining the amount of thermal energy which can be transferred to the cooking pot.
BIS standard for biomass cook stoves Designation Name Test method/s Indicators Max/min values Comments IS 13152 (CIS 1315 Z) (Part 1): 1991 Indian Standards for biomass cook stove specification Water boiling test (Thermal Efficiency), stove hood for emissions tests Thermal efficiency, CO/CO2 ratio, TSP CO/CO 2 ratio less than 0.04, TSP less than 2mg/m 3 First national test methodology designed specifically for improved cook stoves
Comparison with Aprovecho bench mark for wood stoves
Limitations to BIS standards It was developed for one particular type of cook stove, hence did not cater to the various types of cook stoves produced and sold in the market. Testing protocol has thermal efficiency as the main focus. Limited testing centres were limited in number Testing facilities need up gradation and expansion
Revised BIS standards and test protocols BIS standards and protocols for biomass stoves is being revised. Draft is prepared and under consultation It is modified included new stove types such as forced draft stoves, community stoves etc. New emissions standards have been proposed for various types of stoves
Revised BIS standards and test protocols US EPA(5G) method for wood heaters have been followed for designing and developing test facilities at three Test Centres supported by the MNRE CO/CO 2 ratio and TSP measurements have been replaced by CO and TPM respectively The limit of moisture content has been suggested as 5(±1)%
Revised bench marks for stoves Sl. No. Type of Biomass Cookstove Standard Performance Parameters Thermal Efficiency (%) CO (g/mjd) TPM (mg/mjd) 1 Natural Draft Type Not less than 25 5 350 2. Forced Draft Type Not less than 35 5 150
Future plans Star rating for different category of stoves Creation of more field level testing centres in partnership with NGOs/R&D institutions Training and capacity building of testing personnels Field testing centres to help in evaluation of stoves in the field pilot as well as full scale dissemination.
Future plans and monitoring Planning Commission has approved in principle the setting up of a Section 25 Company primarily for promoting cook stoves in the country The MNRE is in the process of setting up the Bioenergy Corporation of India for promoting bio energy technologies such as cook stoves, gasifiers, waste to energy and biogas plants Under the new biomass cook stoves initiatives 110,000 stoves (domestic, community and institutional) to be deployed on a pilot scale MNRE would provide partial subsidy of Rs 400/- (US$ 8) for natural draft stoves and Rs 800/- (US$ 16) for forced draft stoves. This subsidy will be paid after third party verification six months after deployment of cook stoves in the field
Some technical issues to be addressed
Thank you!
