1 Biogas Asia Pacific Forum, Kuala Lumpur 12 June 2013 Indian Biogas Association (iba) Review of Biogas Upgrading Technologies: Efficiency, Bio-methane quality, Investment and Operating cost Gaurav Kedia Chairman, iba Presented By : Vishal Gosai Principal Co-ordinator, iba

2 Structure Indian Biogas Association - an introduction Biogas and Bio-CNG Biogas enrichment processes Financial analysis of Bio-CNG based business model Challenges for Bio-CNG Case study: Muni Seva Ashram

3 Indian Biogas Association IBA aspires to be a unique blend of; nationwide operators, manufacturers and planners of biogas plants, and representatives from science and research. The sole motto of the association is propagating Biogas in a sustainable way. Some of the prestigious members: Vogelsang, Netzsch, Kirloskar, FGP, Arka BRENStech. Some of our past event co-organizers: IIT-Delhi, MNRE, B4E, Renewable World

4 Introduction to Biomethane Biomethane is a methane rich (>90%) flammable gas that results from upgradation of Biogas. Biomethane energy is the use of Biomethane gas to produce heat, power or as a transport fuel. Biogas

5 Utilization of Biogas BIOGAS Drying, Desulfurization Gas conditioning with or without CO 2 separation Compression Reformation (possibly) Boiler CHP Bottling or gas grid Filling station Fuel cell Heat Electricity & Heat Substitute for LPG or nature gas Fuel Electricity and heat

6 Biogas Enrichment Process Absorption into liquid (Physical / Chemical) Adsorption on solid surface Membrane separation Cryogenic separation Chemical conversion

10 Renewable energy country attractiveness indices Plans to make India an emerging bio-economy have led to talks with the US Department of Energy on creating a biomass roadmap', similar to that employed by China. Total biomass potential in India is estimated at more than 70 gigawatt (GW) - E&Y, 2012, URL: goo.gl/4ghkw

11 Biogas upgrading plants - IEA Bioenergy Task 37

12 Annual Biogas Generation Others Tanneries Biogas in Million NCum MW 300 Ncum/hr, 3000 Nos, Potential sites: 159 Paper 300 Ncum/hr, 600 Nos, Potential sites: 210 STPs Distillery 300 Ncum/hr, 300 Nos 500 Ncum/hr 320 Nos Full Market Potential ~ USD 3 billion Target Market Potential ~ USD 1.2 billion Annual Biogas 2000 million NCum Annual CBG potential 900 million kgs

13 Scenario in India Scattered market No established player at national level Market needs someone offering end to end solution Experienced and skilled workforce is lacking Government active intervention is needed Promotion of Bio-CNG is lacking Different approach is needed for small, medium and large scale biogas upgradation plant promotion Supply chain management is to be streamlined

14 Bio-CNG: A need for Indian rural and Industrial sector Many countries like India has the natural resources. It provides a buffer against energy security concerns. It offers a hedge against fossil fuel price hikes and volatility. Off-grid energy supply can meet demand in un-served rural areas. It can be supplied to both urban and rural poor. It can support attainment of a country s climate change goals. Sustainability can be achieved in true sense

15 Financial Analysis Units of Electricity 1 Ncum of Biogas USD $ 0.13/KWh* 0.4 Kg of Compressed Biogas USD $ 1/Kg* USD $ 1/NCum * CAPEX & OPEX almost similar for both type of plants Not to forget Biofertilizer is an intrinsic part of revenue for Biogas business!

16 Financial Projections 1 MWel Equivalent 2500 Amount in Lacs CBG & SUC CBG Electricity Years 100 Lacs = USD Project Cost Project Cost with Grantt Grantt Cumulative Cash Accrual - CBG Cash Accrual

17 Muni Seva Ashram: A Case Study

18 Geographical location MSA Near Vadodara, close to the district border to Panch Kola and not far away from border to Madhya Pradesh. Road and grid access are quite good. Distance to industrial sites (Apollo tires, Suzlon, etc. are quite near, so there is a good chance for third party buyers for power.

19 MSA Mission "To serve the deficient and needy sections of the society, without regards to cast, creed, religion or financial status of the recipient, employing the best available appropriate technologies and in complete harmony with the nature."

20 Biogas, Enrichment and Bottling unit Capacity: 20 Nm 3 raw biogas per hour End use: Vehicular and Thermal

21 Solar Cooling Vapour Absorption Chiller (VAC) refrigeration system that can achieve cooling up to 6 0 C Scheffler dishes allow water to reach temperature of C - Corresponding steam at 8 to 10 kg/cm 2 pressure 100 Tr of cooling out of this solar Air Conditioning System using Scheffler Concentrators

22 Solar Crematorium World's First and only Solar Crematorium System to be backed by biogas for buffer supply

23 Renewable heaven MSA is using solar street lamp, cooker, and many other renewables Sustainability at Ashram has got the human dimension as well!

24 Summary Bio-CNG: Versatile and efficient R&D: Improvement of efficiency and environmental performance of Bio-CNG production and utilization For Bio-CNG development, clear governmental policies are crucial Integration and compensation of Bio-CNG technically, financially and socially Trees can be retained It is a quick, easily controlled fuel No smoke or smell (unless there is a leak) Clean pots

25 Q&A Commonsense is the realized sense of proportion! Gaurav Kedia E: M: A: #B-2/2392, Vasant Kunj, New Delhi , India
