  • 1. S-W Monsoon driven Hydro Kinetic Renewable Energy Resource A Novel India Specific Concept A Presentation at Exploring Energy Frontiers: an interactive summit from IITBAA-GABF Miramar, Goa September 21, 2014 With a Focus on “Improving energy self sufficiency for the country by harnessing the transformative potential of IITians (alumni, faculty and students) as change agents” By Dr. Shrikrishna Sane IITB Alumnus (1964 Batch M. Tech., Mechanical) and Former Professor, Centre for Aerospace Systems & Engineering, Department of Aerospace Engineering, Indian Institute of Technology Bombay, Mumbai (1971-2004). Since 2007, Advisor, Science & Technology, Nostrum Energy LLC (NJ, USA), operating from Powai, Mumbai (India).

ENERGY RESOURCE: RENEWABLE OR NON-RENEWABLE Energy Resource, by definition, must be: Abundant and Accessible, Reliable, Predictable, Technically Feasible, Economically Competitive, and must have Net Positive Benefit over its Life Cycle. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 3
  • 4. Renewable: Rainfall/Snow Melting WATER RESOURCE & HYDRO KINETIC ENERGY RESOURCE : P  V3 Just Rainfall is not a Hydro Kinetic Energy Resource. Wind blowing at 6 m/s 24x365 is not a Wind Energy Resource. Rainfall in US & Indian S-W Monsoon are different. 10/10/2014 4 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US)
  • 5. Renewable: Tropical Monsoon Sorry, Cannot help Boundary Distortions This Map tells many things, which need urgent recognition Tropical Monsoon Regions: (indicated in blue). Monsoon in Indian Subcontinent is special because of Great Himalayan Wall in the North. S-W Monsoon brings 3.5 – 10 m rainfall in 60-120 days almost in equal measure year after year: an opportunity. 10/10/2014 5 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US)
  • 6. 10/10/2014 6 Case of : Western Ghats of Peninsular India The Unexploited Opportunity Miramar What experts say: “Though the west-flowing rivers draining the western aspect of the Western Ghats have substantial run-off, the spatial scope for their wider utilization is limited.” [3] But no more. © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) Kondbhairav
  • 7. Western Ghats of Peninsular India Gross Hydro Kinetic Energy Resource Potential • Consider some Realistic Numbers: • Catchment Area: 100000 km2 out of 180000 km2; • Usable Rainfall: 4.5 m out of 7.5 m with 0.6 runoff; • Duration of Stabilized Flow: 45 days minimum; • Usable Gravitational Head: 100 m out of 1000; • Gross Flow: 70000 m3/s @ Usable Head: 1 MPa; • Gross Hydro Kinetic Power: 70 GW; • Gross Energy Available: 75 TWh/year; • Practical Realization of 2% of 75 TWh Energy Potential will deliver annually: 1.5 TWh of useful energy; with a decent CUF: 0.123 to 0.37 (45 – 135 days); 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 7
  • 8. Western Ghats (WG): Way Forward • WHAT IT IS: 1.5 TWh/year with CUF=0.13-0.37 • HOW IT COMPARES WITH WIND IN INDIA[1]: • In 2012 : 14623 installed MW actually delivered 16428 MU or 16.428 TWh at 13% CUF. • WG are equal to 10 % of Indian Wind Energy. • Higher the CUF better the economics, but we need to carefully work it out. • HOW TO DO IT: Check Dams with Temporary Storages and • Multiple Turbine Units 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 8

  • 15. Changing Paradigms: • Can Renewables stand on own Legs? NO & YES. • Distributed Generation and Consumption Model; (If desirable, is this enmeshed in our thinking and planning? This is going on for a decade). • Moving away from age old ‘Hydro Electric Power’ Mind-Set; US has started the trend [2, 3], Poor Nations will need 50-100 years more, cannot just shut down existing plants. • Innovating Power Extraction Devices for fully confined finite flows; • Total Water Management Concept: Empowerment of the People and Environment 10/10/2014 15 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US)
  • 16. Total Water Management Concept: a citizen’s charter must envision and ensure that • Empowerment rather than Displacement of Humans, Flora and Fauna, as they are primary stake holders. • ‘Distributed Generation & Consumption’ Model: Only Excess Energy & Water to External Consumers & 24x7 electricity in each hospital/school/house. • Prevent Soil Erosion; Generate Fresh Soil Areas through Temporary Storage Hydraulic Structures: Check dams/bunds: Help Ground Water Recharging • Use of Innovative & Appropriate Strategies: Forestation, Herbal Plantation, Grass patches, Agricultural Ponds. • Ensure Water for Drinking, Sanitation, Irrigation and Traditional Industry for the population, tribal included. • Generate Revenues and Create Jobs Locally and Manage Locally at Village Level. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 16

Height AMSL: Kondbhairav (360 m); Nivali (180 m); Nayari (80 m); Hedali (40 m); Total : 320 m. PROPOSAL FOR IMPLEMENTATION: IT WILL NOT COST MUCH. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 17
  • 18. Kondbhairav Pilot Case Study: Resource Potential • Catchment Area = 36 km2; • Rainfall Intensity : 4500/6000 mm in 90 days • Average Cumulative Stabilized Flow in the last 1 to 1.5 km of catchment zone with runoff coefficient of 0.72 = 15 m3/s; • Usable Head: 20 / 320 m in Last 1 to 1.5 km • Flumes: b = 2 m, w = 4 m, d = 1.25 m to ensure V = 3 m/s. • LPTs: l = 3.2 m, s = 0.75, Rated Power = 16.7 kW @ V = 3 m/s. • 30 units in 1000 m to generate 500 kW for 90 days. • Energy Delivered: 1.1 TWh/year. • Decent CUF of (90/365) ≈ 25 %. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 18
  • 19. Kondbhairav: Pilot Case Study: Techno-Economic Assessment • @ INR 4/kWh: Annual Revenue per MW: INR 8.8 million. • Indirect Revenue of ‘Value Addition’: - ‘Total Water Management Model • Estimated Annual Revenue per MW: INR 10 million. • Payback Period: 5 years • Limit Capital Costs to: INR 50 million/MW. • Practically Feasible, but site specific. • Cheaper Compared to Solar by 100%. • Cheaper Compared to Micro Hydro by 150 %. • Prima Facie a Practical/Doable Proposition 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 19
  • 20. Conclusions and Recommendations • A scientifically sound, practically feasible, sustainable, environmentally & socially friendly and commercially competitive scheme to identify, design-develop and exploit potential Hydro Kinetic Renewable Energy Resource Sites, wherever these wait unnoticed. This renewable will have a net positive benefit. • Appropriate Power Extraction Device concept demonstrated in March 2013. • Support urgent Implementation 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 20
  • 21. Conclusions and Recommendations • Most of the nations in the tropical monsoon region are not rich and are in need of Affordable Solutions. • India should lead from the front to develop this technology. • The numbers generated are kept sufficiently conservative so that the conclusions remain valid under all possible uncertainties. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 21
  • 22. Remarks • Power extraction devices, for Wind and Tidal, operate in similar singly confined infinite flow domains. But devices for rivers and canals operate in fully confined finite flow domains and must look different. • I consider this sufficiently fish friendly as compared to conventional rotary ‘choppers’. • This can be a Value addition to existing Hydro Electric Power Installations. • Floating debris is an issue but not insurmountable, so also sealed bearings operating in muddy water. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 22
  • 23. Tasks ahead ….. I look forward to this gathering to take up some of the challenges to get the Technology Details in place: Resource Development & LPT Technology: ‘pocket belts’, ‘bearings’, ‘rotary/linear generators with water gap’, ‘composite blades’, ‘debris removal robots’ to name a few. • We cannot change the way Sun shines or the way Wind blows or even the way it rains but we can somewhat change the way water flows from hill tops to oceans and let the rivers flow……… …. 10/10/2014 © Prof. Shrikrishna Sane, Adviser S&T, NE LLC (NJ, US) 23
  • 24. Epilog This has been SIX years effort of one individual. March 24, 2013 was first time in the world that a classical ‘LIFT’ based Linear Power Turbine was demonstrated in the water efflux of Tata Hydro Power Station at Bhivpuri near Karjat (Maharashtra). Evidence about the effort it took to reach there can be found in the storm water drain canal near NCC office and Hydraulics Lab in IIT Powai campus even today.
