  1. Biomass for Power Generation B.C. JainAnkur Scientific, Vadodara MNRE – ASEAN Workshop New Delhi - Nov. 2012

  2. Biomass : Technology Options • Basic Power Generation Options are Combustion and Gasification. • Combustion is a well-established technology and is particularly suited at higher power levels. • Gasification is more attractive for Distributed Generation up to a few megawatt output.

  3. Combustion based Power – Status in India • Well established technology with a number of key players. • Installed capacity of over 900 MW. • Power ratings between 4 MW and 15 MW. • Wide range of residues and feedstocks in use. • Key issues related to fuel supply chains and feed in tariffs.

  4. What is Biomass Gasification? Basic Process Chemistry • Conversion of solid fuels into combustible gas mixture called producer gas (CO + H2 + CH4) • Involves partial combustion of biomass • Four distinct process in the gasifier viz. • Drying • Pyrolysis • Combustion • Reduction

  5. Gasification – Basic Process Chemistry Schematic

  6. Gasification - The Biomass Arguement … …(Logistics & Management) • A distributed resource like biomass is best used in distributed manner. • Large capacity plants need to cover larger areas for feedstock. • Are more vulnerable on account of availability and price hikes.

  7. Gasification - Technology Status • India emerging as technology leader worldwide. • Exports to over 30 countries in all continents. • Wide range of outputs from a few kilowatts to a few megawatts.

  8. Dual-Fueling &Power for Industries

  9. 5 X 100 kWe at Sundarbans, West Bengal

  10. FBG-350 at Jasoriya Rice Mill, Burdwan

  11. 250 kWe at AIMS

  12. Power to Rural Areas – The Issue of Developmental Models • Large power plants based grid extension. • Decentralized Generation with increasing self-sufficiency for rural areas? • Main focus so far on grid extension but need for an intelligent combination. • For decentralized generation, biomass is the key option.

  13. Small Power Packs in Stand-Alone Mode Distributed Generation - Three Basic Models For remote / isolated villages and communities not connected to a grid and not likely to get connected in the near future. • Small Power Plants in Grid Connected Mode For grid connected rural areas with major problems of power availability and power quality resulting in very limited and poor quality electricity being available. • Co-Generation of Charcoal and Electricity Tremendous potential to address both cooking and electricity needs with very high biomass utilization efficiencies.

  14. Small Power Packs in Stand-Alone Mode

  15. Small Power Packs - Features • Locally available biomass as feedstock. • Power Packs of 10 kW and above. • Self-starting with no external start-up power; requiring less than 10 minutes start-up time. • Could be operated round-the-clock/on-demand. • Biomass consumption about 1.3 kg / kWhr.

  16. Power Pack for Village Electrification Highlights • First installation of GAS-9 100% Producer Gas system • Start-up through battery • Specific fuel consumption: less than 1.3 kg/kWhr • Operated by Women’s Self Help Group • Has become a catalyst for economic growth in the village Gasifier Model: 1 X GAS-9 Odanduthurai, Coimbatore

  17. Small Power Plants in Grid Connected Mode

  18. Guiding Philosophy Size the power plants so that: • Allow benefits to pass on to maximum number of people. • Make the biomass procurement area as small as possible. • Size of power plant such that it can be run like a commercial operationwithout a very high fixed cost. • Standardize for easy Operation, Maintenance and Services. Also for cost cutting.

  19. MW Level Tail end Power PlantsAn Exciting Opportunity • Almost all rural grids have 1-2 MVA capacity • Rural areas / grids feel the power shortage pinch the most – are the first ones to be off-loaded • Appropriate capacity tail-end power plants (0.5 – 2.0 MWe) based on biomass gasification could alleviate/ totally eliminate this problem • And can lead to the realization of the dream of equitable, round-the-clock quality electricity supply to Rural India

  20. 1.2 MW Power Plant at Sankheda, Gujarat

  21. Projects Around the World – A Glimpse
