1 OVERVIEW OF BIOGAS IN INDIA ANIL DHUSSA ADVISER, MINISTRY OF NEW AND RENEWABLE ENERGY, NEW DELHI

2 Indian Pwer Sectr at a Glance Renewable, 13% Nuclear 2% Gas, 9% Thermal, 58% Hydr, 18% Ttal installed capacity : 2,30,000 MW Thermal 1,56,000 Hydr 40,000 Gas 21,000 Renewable 30,000 Nuclear 4800

3 Indian Renewable Energy at a Glance Small Hydr 3,770 MW 13% Slar 2200 MW 4% Ttal Installed capacity 30,000 MW Bi Pwer, 3,800 MW 14% Wind, MW 69%

4 Renewable Energy in India - Credentials 5 th Psitin in verall RE Capacity Installatin wrld-wide 5 th largest Wind Pwer capacity 2 nd largest number f Bigas plants 6 millin decentralized RE systems Renewable is the secnd largest surce f pwer generatin after thermal.

5 Ptential f Bigas in India Agricultural residues / energy crps 141 M.ha. f arable land prducing ver 700 MTA bimass estimated surplus ~ 150 MTA 50 M.ha arable land is under mn crpping - ptential fr shrt cycle cellulsic bimass. Cattle dung and Pultry drppings 1000 MTA frm 300 millin cws & buffales. 8 MTA frm 500 millin pultry birds. MSW By 2020 urban ppulatin likely t be 550 mil - wuld generate > 100 MTA f MSW

6 Imprtance and Relevance f Bigas Agricultural residues / energy crps Bimethanatin f Bi-waste enhances energy security thrugh efficient utilizatin f lcal resurce. Manure AD prduces superir rganic manure, required fr sustaining sil fertility. Industrial AD Plant residues can be treated t prduce rganic fertilizer f assured quality Municipal Slid Waste Rapidly grwing urban pllutin and scarcity f land necessitate alternate slutins t landfills Decentralised Bigas Plants fr treating segregated rganic MSW wuld be an effective slutin

7 Bigas in India A few brad applicatins 4.7 M Husehld bigas plants based n cattle manure mainly fr prducing cking fuel Mid sized bigas plants based n cattle manure and ther similar wastes fr heat, electricity r mtive pwer Bigas frm urban and industrial wastes and effluents C-digestin f farm / agricultural residues with urban and industrial wastes

8 Sme Recent Prjects 2.4 MW prject based n mix f pultry drppings, cattle manure alng with sme agr industrial wastes after MW scale prjects based n nly cattle dung Abut ten prjects n prductin and upgradatin f bigas t Cmpressed Natural Gas Quality fuel. Capacity ranges frm 0.4 t 8 TPD bi-cng. 1.6 MW pwer frm sugar industry slid waste Bi-CNG and Pwer frm bigas at distilleries and STPs Bigas upgradatin t Natural Gas Quality, Bi-CNG, fr use as transprt fuel These prjects are in additin t the husehld units, small and large pwer generatin prjects based n cattle manure and industrial wastes

9 Bigas Plant Designs Tp: Flating drum Bttm:Fixed dme

10 Bigas frm Industrial Wastes Likely WTE Capacities Distillery effluent : 1 MW / 30 kl Dairies (milk prcessing) : 100 kw / 3 lakh litres Paper Mills (Black Liq.+) : 1 MW / 60 TPD paper Slaughterhuse waste : 100 kw / TPD Pultry drppings : 1 MW / 1 Millin birds Cattle manure : 100 kw / 25 TPD

11 Bigas frm distillery spent wash: Capacity Bigas prductin Pwer generatin : - Steam turbine rute - Reciprcating Engine 30 kl cum./day 0.5 MW 1 MW One f the majr surces Cst Payback perid Rs. 45 Mill / MW 3-4 years

12 Bigas Prject at a Dairy Cmplex in Ludhiana Capacity: 1.0 MW pwer frm bigas prduced frm abut 250 tnnes/day f cattle manure

13 1.2 MW pwer prject based n cattle manure Dairy Clny in Jabalpur

14 Bigas frm bagasse wash water Tamil Nadu Newsprint and Papers Cmpany

15 Bigas frm slid waste at Slaughterhuse Capacity: 3000 cum / day

16 Bigas frm Sugar Industry Slid Waste (Press mud) Sugar Industry prduces slid waste knwn as Press Mud Quantity f Press Mud prduced is abut 3.5 t 4% f the sugarcane crushed Bigas yield per tnne f press mud : 100 cum. (40 kg Bi-CNG r 50 litres diesel) Bigas yield per tnne f cane crushed: : 4 cum. (1.6 kg Bi-CNG r 2 litres diesel)

17 Characteristics f Bi-CNG Parameters Bigas Bi-CBG Methane (v/v) 55-65% 92-98% CO 2 (v/v) 35-45% 2-8% H 2 S (ppm) ,000 <20 ppm Misture Saturated < -40 deg Other Impurities Present Nt present Calrific Value (LCV) 1 kg f BiCBG= 1.5 liter f Petrl ~ kj/kg ~ kj/kg 17

18 First large scale Bi- CNG plant in India 18

19 Bigas cleaning system fr H 2 S remval 19

20 Bigas cleaning system fr CO 2 remval 20

21 Bi-CNG Cascade 21

22 Use f digested press mud as Organic manure Maize Cabbage 22

23 Gvernment Supprt fr Bigas Prgramme Subsidy fr installatin : ~20% f cst Preferential tariff fr sale f generated electricity Fiscal Incentives / Cncessins - Accelerated depreciatin - Imprt duty - Excise duty fr RE devices - Incme Tax Spnsrship fr Research and Develpment

24 Other Plicy Measures fr prmtin f Bigas Prgramme Open access t electricity grid fr the pwer frm renewable surces including AD Preferential tariffs assigned by State regulatrs fr sale f electricity RE Pwer Obligatins fr Transmissin Cmpanies Captive generatin decntrlled Plicy framewrk fr pumping upgraded Bigas int gas grids and fr price fixatin fr Bi-CNG wrk in prgress
