PREFACE

India is one of the largest and fastest growing markets for renewable energy in the world. At the same time, due to

the size of the population and the growth of the economy, the increase in absolute terms of energy produced by

conventional fossil fuel is going to be very high.

It is therefore very critical to reverse this trend in order to achieve effective results in the global efforts against

climate change. Improving the efficiency and the technology for renewable energy is one of the key answers.

After an overview of the present scenario and the projected growth in the next decade, this report aims to highlight

some of the priorities identified in India for R&D and technology transfer in this direction.

This survey has a limited scope and it is concentrated only on the initiatives stimulated at the central level. There are

25 regional States in India with their own policy for energy and renewable energy, and various other institutional

and local initiatives that are not covered here. We are also providing a sample overview of key agencies operating

in the renewables sector sector, selecting among those that have national relevance. But it is far from being

exhaustive.

India is a large country with many public and private institutions and many local decentralized initiatives. Many

activities in this field are also originating through community-based actions, and we did not aim to give a full

extensive presentation. Our purpose is mainly to give a first indication to European companies, organizations, and

research institutions about new field of opportunities for Transfer of Technology, and to make a small step toward

widening the knowledge and scope for cooperation between Europe and India.

1. THE RENEWABLE ENERGY SECTOR IN INDIA

1. SCENARIO AND GROWTH

At present India has a share of 10% of installed power capacity that is generated by renewable sources, of

which 2/3 are originated from wind. In the early nineties an ambitious program was started to promote wind

energy in the private sector, offering an accelerated depreciation rate for investments in wind turbines, and

allowing power purchasing by the State Electrical Board from Private parties at higher-than-market rates. As

a result, India has become the 4th largest country in the world in terms of installed capacity of wind turbines,

with more than 14,100 MW.

The Indian Government is trying to diversify sources of renewable power, especially in small hydro, biomass

and solar energy. Currently mini-hydro has an installed grid-connected capacity exceeding 3000 MW, biomass

more than 2600 MW, whereas the installed grid capacity in solar is less than 100 MW. However, solar power is

at the center of the core strategy of the Indian Government to invest an additional 34 billion USD in order to

add 17 GW of renewable energy generation.

Growth in the renewable energy sector is driven by several factors:

• An increasingly wide gap between supply and demand

• The need to reduce the pressure on the balance of payments for imports of fossil fuels (80% of domestic

crude consumption is imported and 30% of total imports goes for oil imports)

• The need for viable solutions for rural electrification

• The pressure to abate GHG emissions

The estimated existing capacity and potential for growth in key segments in Renewable Energy is shown in Table

1 below.

Table 1: capacity and expected growth in renewable energy in India

SOLAR PV and CSP WIND BIOMASS SMALL HYDRO

Total potential 5,000 trillion kWh per year 48,000 MW 23,700 MW 15,000 MW

Installed capacity (june 2011) < 150 MW 14,000 MW 2,670 MW 3,000 MW

Projected capacity in 2022 20,000 MW 50,000 MW 10,000 MW 5,500 MW in 2015

The estimates of growth and future potential are a function of a few variables. The share of Solar PV and Solar

CSP still has to be determined and properly predicted, as the latter is a relatively new technology for India.

At the moment, the installed capacity in CSP is negligible, although 500 MW has been allocated under the

Jawaharlal Nehru Solar Mission and there are expectations to have at least 1,000 MW installed in the next 2-3

years. A certain attention is being paid to the CSP technology because, theoretically, it is more efficienct under

Indian conditions and is lower in price. One of the constraints is currently the big size of the plants. European

technology that can offer CSP plants on a smaller scale is therefore particularly relevant for the Indian market.

6


The potential for wind is estimated on the basis of existing technology. With technological improvements in the

turbines the potential for on-shore wind energy could be doubled. The total capacity for biomass is estimated

based on the current availability of raw materials, but the potential can increase with the production of feed-stock

and energy crop plantations.

Small hydro is a sector that has witnessed a relevant change of trend and a big growth in investment from 6.17

billion of rupees in 2007 to 26.45 billion 2010, representing 15% of the total investment in renewable energy. At

current growth rates, the installed capacity could be in the range of 5,500 MW by 2015.

In the next decade India is projected to be the third country in the world, after the USA and China, in terms of

investment in renewable energy, just ahead of Germany and the UK. Financial Incentives play a relevant role in

the development of the sector. The different types of financial mechanisms vary according to the specific needs

of each segment and the cost of generation. The different types of incentives provided by the Central Government

are accelerated depreciation rate, tax benefits, exemptions from customs duty, excise and sales tax, feed-in tariff

at a premium and capital subsidies. In addition to the incentives provided by the Central Government there might

be incentives provided at the regional level by the State Government.

Table 2 shows the categories of incentives applicable to the different segments of renewables, compared with cost

of generation.

2. Need for R&D and transfer of technology

A dedicated ministry, the Ministry of New and Renewable Energy (MNRE) was established in India in 1992 with the

aim to coordinate policy and incentives for non-conventional energy sources, and to promote R&D in the sector.

The R&D strategy of the MNRE is based on the involvement of industry and research institutions on four levels:

• Development of innovations

• Improvement of existing and indigenous technology

• Transfer of technology for technological development

• Assignment of specific R&D tasks to recognized institutions or industry

2.1 Solar energy

Solar energy has been identified by the MNRE as a thrust area for India, given that India has an exteremely high

solar reception capacity (600 TW per year). The grid connected capacity is still minimal, but there are many big

projects in the pipeline since the launch in 2009 of the Jawaharlal Nehru National Solar Mission (JNNSM).

The JNNSM has a strong emphasis on increasing manufacturing capabilities inside the country. Transfer of

technology is actively sought for:

- Solar collectors for medium and high temperature applications

- Thermal devices and systems (including thermodinamic)

- Thin film modules in silicon

Special Incentive Packages (SIPs) are provided to set up manufacturing units in the sectors of solar components and

devices, using technology not yet available in the country. SIPs might provide fiscal and customs benefits as well as

infrastructure facilites if the unit is located into a recognised technology park.

Priorities in the R&D sector are given to:

- Improvement of efficiency in existing materials, devices and applications

- Reducing costs of balance of systems

- Integration and optimization

- Cost-effective storage technologies targeting space-intensity through the use of better concentrators and

nano-technology

R&D strategies are oriented toward multiple directions:

1) Long term research for new materials and processes

2) Improvement of existing processes and technologies

3) Pilot and demonstration projects

4) Development of R&D infrastructure in PPP modes

5) Support for incubation and start-up

A National Center of Excellence (NCE) will provide a national platform to network the various R&D initiatives,

including foreign collaboration and transfer of technology and to operate as a funding agency. In the pipeline there

also are funds to incubate the creation of at least 50 start-ups in solar related technologies in the next five years.

8


The overall strategy of the MNRE in the solar PV sector is to reduce the consumption of silicon and other materials

and improve the efficiency of solar cells and modules to achieve cost reduction. The following key areas of research

have been identified:1

• Polysilicon and other materials

• Efficent silicon solar cells

• Thin film materials and solar cells modules

• Concentrating PV systems

• PV system design reducing the ratio of capital cost to conversion efficiency

For Solar Thermal Power generation the area of researches are related to:

• Parabolic technology with provision to connect to the grid, for a plant of at least 1 MW

• Central receiver technology to install plants with molten salt as heat transfer and storage medium, heliostats

tracking mechanism, tower structure receiver and storage medium

• Dish/Engine technology for solar dish with Stirling engines and for thermal power plant in the range of 100

Kwh and above

• Development of Stirling engines suitable for families, community and distributed power generation

Beyond power generation, R&D in the Solar Thermal segment are undertaken for Solar Heat to be employed in

industrial processes (250°C) and low temperature applications like distillation and water purification, solar cooling,

solar thermal devie and waste detoxification.

2.2 BIOMASS

In addition to solar energy, biomass power generation is the target of another dedicated national mission. In the

nineties India undertook an important program for biomass for bagasse co-generation in the sugar sector, which

has constituted its main end-use until now.

Priority is now given to energy and heat generation from other biomass sources, which include mainly wood

masses such as Jatropa, Bamboo, Melia Dubia, Casuarina equisetifolia and other raw materials such as rice husk.

Biomass from algae is a new avenue for research.

Biomass is one of the main sources of energy in rural India and contributes to about 27% of total primary energy

consumption in the country. Most of the biomass is still used mainly in the traditional way, and only a small

share is converted in energy and heat through a technological process. However, as the potential in this sector is

significantly high, the Government of India has identified development of biomass as one of the priority areas for

its rural electrification programme.

According to the Indian MNRE the present trend of investment in biomass in India is in the range of 100 million

euros per year, with a total number of people employed around 10 million2.

In India the total installed capacity for biomass energy generation is of 2,650 MW (as of the end of June 2010,)

out which approx 1,100 MW are generated from agro residues and the balance from bagasse. There is a total

1 See Appendix 1 for full details of R & D Thrust area of the MNRE 2 Source: www.mnre.gov.in/prog-biomasspower.htm

9


number of 160 biomass plants generating greed connected power and about 70 plants for co-generation. The total

estimated potential for biomass in India is 23-25 GW. In India there are four types of technologies adopted for

Biomass energy generation:

- Combustion

- Anaerobic digestion

- Gasification

- Pyrolysis

Combustion is used for over 85 % of power production plants, using rice husk, bagasse, groundnut shells, jute

waste and cotton stalks either for co-firing with coal or for co-generation, especially in the sugar sector.

Anaerobic digestion is not yet diffused as it is a technology mainly applicable to the treatment of municipal or

industrial waste for which there is not yet a properly organized supply-chain in India.

Gasification and Pyrolysis are new technologies which have a strong priority for research in India. Especially in

gasification India is establishing itself as country leader in this segment. The reason is that Gasification is particularly

suitable and economically convenient for small plants below 2 MW, which can be adapted for captive industrial

purpose or rural electrification in the villages.

The development of gasification technology is the joint target of the Ministry of Non Conventional Energy Sources

and the Ministry of Agriculture.

A network of R&D centers has been created throughout the country to implement a programme on biomass

gasification and gasifier system designed for a variety of locally available biomass.

These institutions are located at IISc (Indian Institute of Science) Bangalore, IIT Chennai, IICT Hyderabad and BHEL

Triuchirapalli for the advancement of technology for generation of power from biomass. Gasifier action research

projects are also being supported by IIT (Indian Institute of Technology) Delhi and Mumbai, IIS Bangalore, MKU

Madurai and SPRERI (Sardar Patel Energy Research Institute) Vallabh Vidyanagar.

India has the largest number in the world of gasifier installations and a few manufacturers of gasifiers.

Gasifying is a sensitive technology. The performance of raw materials depends a lot from the fuel and different raw

material might require different machines or suppliers. Also the quality of gas produced is a critical point to verify

gas composition, energy content, impurity and other chemical and physical parameters can change a lot depending

on the equipment and the type and condition of the raw material.

India uses both downdraft and updraft technology, although downdraft technology is the most commonly used.

The main demand of R&D or TT in the biomass sector is in the following segments:

- Long stick biomass gasifier

- Huge density and high moisture acceptability biomass gasifier

- Multi-fuel acceptable biomass gasifier

- Advanced biomass gasifier based power plant

10


- Activated carbon reactor

- Producer gas synthesis for transportation fuel

- Pyrolysis reactor for thermal and power

- Pyro-oil with Bio-char for sustainable agriculture

2.3 WIND

Wind is likely to remain for years one of the largest sources of renewable energy in India. The potential capacity

can be further expanded with improvement of turbines. In this segment there could be an important TT demand

for technologies to support installation in lower wind regime and Storage Solutions.

The R&D priorities set by the MNRE are:

• Indigenous design, development and manufacturing capability for MW-scale Wind Electric generators

(WEGs)

• Design, development and manufacturing of small WEGs up to 10 kW capacity, that can start generating

power at very low cut in speeds (~ 2 to 2.5 m/sec).

• Design, development and manufacture of submersible direct drive wind pumps in different capacity ranges

(up to 10 HP) for low wind regimes.

• R&D on carbon fiber and other new generation composites etc.

• R&D on high efficiency electronics for protecting, controlling, optimizing performance, power management

& conversion and establishing connectivity with the grid to export or import power.

2.4 SMALL HYDRO-POWER

Like Wind, the development of Small Hydro-Power is a program that was launched in India in the nineties and the

12th five years plan has envisaged a target of 6,000 MW installed. The total estimated potential for this segment is

beyond 15,000 MW. Initially Small Hydro-Power projects (below 25 MW) were promoted mainly from the public

sector, but now they are increasingly being implemented through private initiatives. Manufacturers of equipments

and components for this segment are based in the country.

The priorities identified by the MNRE are related to Engineering & Manufacturing, civil works and design.

E&M Works

• Adaptation of high pole permanent magnet excitation generators to small hydro

• Development of low speed generators (direct-drive low-speed generators for low heads)

• Development of submersible turbo-generators

• Development of high efficiency turbines in kW range

• Flexible small hydro turbines for low head (<5 m)

• Development of screening systems for downstream and upstream migrating aquatic life

• Development of standardized control and monitoring systems

11


• R&D for development of technology packages for Mini/ Micro hydrosystems fitted with suitable electronics

and optional maintenance-free-rechargeable batteries for their use for lighting and other small power

applications in capacity range of 200 W to 5 kW for highly decentralized and dispersed applications.

Civil Works

• Development of software that allows a fast and efficient civil work design

• Development of standardized and systemized hydraulic structures

• Development of efficient desilters with high head intakes, of self-cleaning water intakes, and of trash racks

• Guide on the design of power houses

Others

• Development of good-practice design guidelines for developers and engineers

• Development of standards and control procedures dedicated to small hydro

• Guidelines for improved methods for in-stream flow and hydrological assessment methods and improved

sedimentation management

• Standards for small, mini and macro hydro power projects and systems

2.5 NEW TECHNOLOGIES

2.5.1 Geothermal

Geothermal generation has a potential of 10,000 MW but there are no plants presently installed. The main factors

restricting the development of this sector are the long gestation period and the lack of record for this technology in

India. Few companies however are making a move in this field like LNJ Bhilwara, Tata Power and Thermax. In India

there is a demand of expertise for R&D in this field and scope also for Transfer of Technology.

2.5.2 Tidal Energy

Tidal energy has a potential of 9,000 MW, with site identified mainly in Gujarat and in the Ganges delta in West

Bengal. There is no significant installation but the government of Gujerat has announced, in January 2011, a project

of 50 MW that will be eventually the first commercial tidal project in Asia.

2.5.3 Wave Energy

Wave energy has a potential of 40,000 MW but there are neither installations nor plans announced.

reactor, which can demonstrate a capacity up to 100 TPA. The quality of polysilicon material produced at the

pilot plant will be suitable to make high efficiency (>15%) silicon solar cells and the combined trace impurities

of heavy metals, carbon and boron will be l imited to ppb.

ii. To design, develop and demonstrate at pilot plant scale (about 100 TPA) poly silicon deposition reactors, based

on traditional poly silicon deposition methods, to reduce the energy consumption to less than 125 kWh/kg of

poly silicon material produced, with the combined trace impurities of heavy metals, carbon and boron limited to

ppb level.

Crystalline Silicon Solar Cells & Modules

1. To reduce the direct consumption of silicon wafer (3 gm per Wp) in commercial production by reducing the

wafer thickness and increasing the efficiency of crystalline silicon solar cell to average 18% and more

2. To develop and produce multi crystalline silicon ingots / wafers and produce solar cells with conversion

efficiency of 17% and more in commercial production

3. To undertake R&D on alternative device structures to make crystalline silicon solar cells to demonstrate very

6. Study and evaluate new materials for use in PV modules

7. To develop low resistance metal contact deposition materials and processes

Thin Film Solar Cell Modules

Thin film solar cell modules have potential to reduce the cost of solar modules due to consumption of less material

and energy in the fabrication processes. Amorphous silicon thin film solar cells were the first to be developed. In

the recent years pilot plants and a few commercial plants based on other thin film solar cell modules (CdTe, CIGS,

silicon) have been set up. It is proposed to take up R&D and pilot plant demonstration of thin film based modules

in the country during the 11th plan, with the following objectives.

29


1. To undertake R&D on different processes and device structures to make laboratory scale small area (2cm x

2cm) devices of efficiency >10% using CdTe, CIGS and silicon thin films

2. Development of poly crystalline thin film integrated modules (1 sq ft or more) at pilot plant scale using different

materials (CdTe, CIGS, silicon films) to achieve efficiency of >8% and life of integrated module > 15 years)

New Materials based Solar Cells

In the recent years worldwide R&D efforts are being made to study new materials, which are easy to deposit and

consume significantly less energy. Thin film modules based on organic materials, dye sensitized and doped with

nano materials have potential to produce solar cells. However, these device structures are in the early stages

of development. It is proposed to established R&D centers in the country to study these concepts and pursue

research in these emerging PV devices.

1. To study and characterize new materials to determine their suitability for fabrication of solar cells

2. Design and development of new thin film device structures based on dye sensitized (liquid and solid state)

organic, carbon nano tubes, quantum dots etc. materials. The laboratory scale efficiency of 5 – 10% to be
