Abstract: Indian economy has
registered an unprecedented growth since 1992 and its energy demands continue
to grow with India and Japan vying for the position of third biggest energy
consumer after Unites States of America and China. But with most of these
energy requirements being fulfilled by fossil fuels and India not possessing
any significant resources of crude oil, around 80% of the needed petroleum is
imported which drains the nation of much needed foreign exchange. So, a programme
to develop indigenous energy resources to meet our needs has to be developed
and biodiesel can be the answer to India’s problem with the central government
also recognizing this.




 Overall petroleum import bill of India, which includes
shipments of both crude oil and petroleum products, rose 9 per cent
last financial year to $ 80.3 billion due to seven percent rise in volumes and
a three percent increase in the average crude price. Crude oil imports rose by
more than five percent to 213 metric tonne (MT) and the crude oil import bill
increased by more than nine percent to $70 billion last fiscal as compared to
$64 billion recorded in 2015-2016.
Increase in India’s petroleum products by volume
was 22 percent last fiscal year to 36 MT from 29.5 MT in 2015-2016. 

Altogether, the country imported around 249 million metric
tonnes (MMT) of crude and petroleum products during 2016-2017,which equals a
seven percent growth over 232 MT imported in previous fiscal year.
The Indian basket of crude consists of the following
composition- 71 per cent of Oman and Dubai grades and 29 per cent of dated
Brent ,according to data published by Petroleum Planning and Analysis Cell
(PPAC) which is the oil ministry’s technical division.
According to data available on PPAC, petroleum
product production – including petrol, diesel and LPG from indigenous crude
fell one percent to 34.7 million tonne (MT) last fiscal year from 35.2 MT in
2015-2016, while the country’s consumption of petroleum product increased by
five percent to 194 MMT. The country’s self-sufficiency in petroleum products
declined from 22 percent in 2013-2014 to 18 percent in 2016-2017 due to strong
consumption growth and declining domestic production.
India’s import dependency on crude further
increased marginally to 82 percent in 2016-2017 from 81 percent a year ago.
Import dependence stood at 77.6 percent in 2013-2014. On petroleum products’
exports front, India’s shipments grew seven per cent to 65 MT last fiscal. The
Oil Marketing Companies accounted for 20 per cent of the exports volume.



. With an
approximate import dependency of 80%, energy security favours the adoption of
20% diesel blending with Jatropha biodiesel (B20). According to the Planning
Commission (2003), 13.4 million hectares of waste land in India can be used for
Jatropha plantations. The Indian government’s initiative to promote the
plantations of Jatropha saplings under National Rural Employment Guarantee
Scheme (NREGS) is a sincere move towards the integration of Jatropha to energy
production. In India, researchers have observed that Jatropha biodiesel and its
blends with diesel can be used in existing diesel engines without any
modifications (Banapurmath et al. 2008; Sahoo and Das 2009; Sahoo et al. 2009;
Kumar et al. 2012a). In the longer run, the economic sustainability of Jatropha
biodiesel will definitely prove to be the best bet for India as far as the
economic viability of biodiesel with respect to diesel is concerned (Kumar et
al. 2008c). With rapid increase in population in Asia, arable land area
is decreasing and it is already only 0.1 hectare per person, on average, in
several densely populated countries, which means that it cannot be used for
biofuel plantations. Establishing biofuel plantations like Jatropha on degraded
soils can be a win-win strategy provided that these soils are adequately
restored and specific problems (e.g., nutrient and water imbalance, loss of top
soil, shallow rooting depth, drought stress, salinization, compaction,
crusting) alleviated. Considering households, the average energy requirements
per capita is 20% less in rural areas compared to urban areas (Pachauri 2004).
It is obvious that a significant rise in energy consumption is expected from
the improvement of living condition standards and population increase (Parikh
and Lior 2009). Rural bioenergy is still the predominant form of energy used by
people in India. Thus, meeting income generation and irrigation management
through renewable sources provide a large potential for sustainable
development. In rural areas, particularly in remote locations, the distribution
of energy generated from fossil fuels can be difficult and expensive. Renewable
energy can facilitate economic and social development in communities if
projects of sustainable development are intelligently designed and carefully
executed with local inputs and cooperation. In poor areas, the renewable energy
projects would absorb a significant part of participants’ small incomes.
Investigations in this direction have been based on the following concepts
namely: renewable energy sources can be replenished in a short period of time
and it is clean, i.e., it produces lower or negligible levels of greenhouse
gases and other pollutants when compared with the conventional energy sources
they replace (Demirbas and Demirbas 2007). One of the major synergic effects on
the economic return of a state investment in biodiesel would be the
availability of facilities for power generation in close proximity to the area
of biomass production. Such structural investments can result in manifold
increase in employment opportunities.190 man days of employment in the first
year and 114 man days in the second year per hectare for poor people living in
rural areas may prove to be a potential source of income generation.
Considering the average man days for first and second year for 150 days
employability in a year, Jatropha cultivation on 13.4 million hectares of
wasteland will result in 300 days/year employment for roughly 6.5 million
people through social schemes of Government of India, such as the National
Rural Employment Guarantee Schemes (NREGS) for people of rural areas. Because
of the uneven distribution of wealth and the large population size, India is
passing through social unrest in many parts of the country leading to large
scale violence in many forms. The creation and development of such local
opportunities in poor rural areas would also help in relaxing social unrest due
to poverty.




took initiatives on biofuels nearly a decade ago to reduce its dependence on
oil imports and improve energy security. A 5% ethanol blending pilot program was
started in 2001 and a National Mission on Biodiesel was developed in 2003 to
achieve 20% biodiesel blends by 2011–2012.1 Like various other nations around
the world, India has endured setbacks in its biofuel program due to supply
shortages, sharp fluctuations in oil prices and global concerns over food
security. Its National Policy on Biofuels, adopted in December 2009, proposes a
non-mandatory blending target of 20% for both biodiesel and ethanol by 2017.
The formulation of the National Mission on Biodiesel in 2003 was the first step
for developing biodiesel program in India. The program called for mandatory 20%
biodiesel blending by 2011–2012, with jatropha curcas as the primary feedstock.
Jatropha, a small shrub that grows on degraded land and produces nonedible
oilseeds, can be used to manufacture biodiesel. Among the 400 nonedible oilseed
crops found in India, jatropha was selected for the program because of its high
oil content (40% by weight) and low gestation period (23 years) compared with
other oilseed crops (GOI 2003). To meet the 20% blending target, the
recommendation was to cultivate jatropha on 17.4 million hectares (ha) of
underused and degraded lands. The biodiesel program was to be implemented in
two phases: a research and demonstration phase from 2003 to 2007 (Phase I) and
an implementation phase from 2007 to 2012 (Phase II). The main goals of Phase I
were to cultivate 400,000 hectares of land, establish a research network of 42
public universities, and achieve a 5% blending target. Under Phase II, a 20%
blending target would be achieved by 2011–2012. To support the program, the
Ministry of Petroleum and Natural Gas ratified the National Biodiesel Purchase
Policy and set a price of Rs25.00 per liter, subject to periodic review,
effective 1 November 2006. The ministry designated 20 oil marketing companies
(OMCs) in 12 states as purchase centers. The buyback program remains in effect,
but the purchase price was raised to Rs26.50 per liter in October 2008.
Although the biodiesel blending targets were not codified, interest in jatropha
accelerated after the introduction of the National Mission on Biodiesel. India
was the world’s leading jatropha cultivator in 2008, controlling about 45%
(407,000 ha) of the global cultivation area (about 900,000 ha) in 2008. More
recent estimates show an increase cultivation area in India to 900,000 ha in
2011. Further, the 11th Five-Year Plan recommended a blending target of 5%
biodiesel by the end of 2012, a significant reduction from the 20% target
proposed under the National Mission on Biodiesel. In September 2008, the
Ministry of New and Renewable Energy resumed discussions on biodiesel and
issued a draft National Biofuels Policy. The policy proposes the establishment
of a national registry of feedstock availability to help monitor production
potential and set blending targets. The Ministry of New and Renewable Energy is
tasked with implementing the policy. Two new committees—the National Biofuel
Coordination Committee under the prime minister, and the Biofuel Steering
Committee under the cabinet secretary—have been formed to coordinate and
implement the policy.

price of oil cake Rs 2/kg, and hull Rs 1/kg



Further treatment of Jatropha oil
into biodiesel by single stage transesterification process by using KOH and
ethanol carries some more costs like a processing machine with a capacity of
200L/day of Rs. 50,000 and all the variable costs like catalysts, electricity, labor
and machine maintenance coming out to be about Rs. 8000.

Therefore, the total investment for
the plantation for producing biodiesel per hectare comes out to  be =  Rs.
2,54,780.325 (14,300+1,82,480.325+58,000)

Now, this amount is equivalent to
4005 USD.


1 hectare of biodiesel cultivation
yields about 7 tonnes of seeds per year. The oil pressed from 4 kg of seeds is
needed to make 1 litre of biodiesel which puts the yearly yield to about 1750
litres. 1 barrel of crude oil is about 159 litres in volume ,so one hectare of
Jatropha plantation can produce about 11 barrels of biodiesel

The amount of biodiesel that can be generated
form one hectare comes out to be around 1750 litres which is roughly around 11


in India about 142 million hectares of land is under agriculture. It will be
reasonable to assume that farmers will like to put a hedge around 30 million
hectares of their fields for protection of their crops. It will amount to 3.0
million hectares (notional) of Jatropha curcas plantation. Using Jatropha as a fencing plant only,3 million
hectares can potentially produce 33 million barrels of biodiesel per year.
After this start, plantation to rehabilitate 13.5 million hectares wastelands
can also be carried out further providing impetus to indigenous biodiesel
production. India’s imports of crude oil in December 2016 were 4038000 per day
which makes our recent consumption to about 1.5 billion barrels per year.

So, from
the above figures it can be seen that by planting Jatropha as hedge only, we
can start the process effectively to reduce our dependence on imported energy
resources. If the possibility to explore plantation of Jatropha on wastelands
is explored, then the potential production can touch 150 million barrels a year
which is more than sufficient to cover the energy needs of rural areas
effectively and to cover the existing blending targets.

coming to the economic factors, we currently spend about $70 billion in
importing crude oil. The initial investment costs as seen is about $4000 per
hectare in case of Jatropha plantations. 3 million hectares of land can be planted
with Jatropha just as a hedge around the food crops on cultivable land without
any special measures in India and good yields can be obtained in a short time
as well as the plantation land would be fertile. The total investment required
for this measure would be around $12 billion to sow, extract oil from the crop
and then process it into biodiesel which would give a yield of approximately 33
million oil barrels per year. With plans to rehabilitate wastelands through
Jatropha, various corporates can be attracted to make this investment which
would also result in the creation of jobs in the processing plants in the rural
areas itself. With the creation of jobs in the rural areas, more citizens can
be brought into the taxpayers’ bracket, thus increasing government’s revenue.






can be effectively explored as a means to alleviate economic distress faced by
India by the import of crude oil. India’s energy demand is set to increase
sharply in the future which makes this measure more necessary. Planting
Jatropha as a hedge to various food crops can be good way to ensure that the
yields are high from the first year itself. The investment required to
kickstart biodiesel production is surely substantial and  the government will have to be pro-active to
interest the farmers in planting Jatropha. But, the returns can be expected to
be extremely fulfilling with our rural communities becoming self-sufficient.
Moreover, the savings can be directed to the education sector, even for
research purposes alone so that continuous ways to make biodiesel more
efficient are investigated to reap more benefits in the future.
