BIO-FUELS
‘biofuels’-are liquid or gaseous fuels produced from biomass
resources and used in place of, or in
addition to, diesel, petrol or other
fossil fuels for transport, stationary, portable and other applications.
‘biomass’- resources are the biodegradable fraction of products,
wastes and residues from agriculture, forestry and related industries as well as the biodegradable fraction of
industrial and municipal wastes.
‘bio-ethanol’:- ethanol produced
from biomass such as sugar containing
materials, like sugar cane, sugar beet, sweet sorghum, etc.; starch containing materials such as
corn, cassava, algae etc.; and,
cellulosic materials such as bagasse, wood waste, agricultural and
forestry residues etc. ;
‘biodiesel’:- a methyl or ethyl
ester of fatty acids produced from vegetable oils, both edible and non-edible,
or animal fat of diesel quality; and ,
other biofuels:biomethanol,
biosynthetic fuels etc.
--Biofuels have been around as long as
cars have. At the start of the 20th century, Henry Ford planned to fuel his
Model Ts with ethanol, and early diesel engines were shown to run on peanut
oil. But discoveries of huge petroleum deposits kept gasoline and diesel cheap
for decades, and biofuels were largely forgotten. However, with the recent rise
in oil prices, along with growing concern about global warming caused by carbon
dioxide emissions, biofuels have been regaining popularity. Gasoline and diesel
are actually ancient biofuels. But they are known as fossil fuels because they
are made from decomposed plants and animals that have been buried in the ground
for millions of years. Biofuels are similar, except that they're made from
plants grown today.
There are various ways of making
biofuels, but they generally use chemical reactions, fermentation, and heat to
break down the starches, sugars, and other molecules in plants. The leftover
products are then refined to produce a fuel that cars can use.
Production of Bio-ethanol(C2H2OH-same
stuff as in alcoholic drinks) involves the conversion of a feedstock crop into
fermentable sugars through enzyme amylases. Yeast is then added to ferment the
sugars into alcohol and carbon dioxide. The main crop used in bioethanol
production varies throughout the world – in Brazil, sugar cane is
preferred(some cars there can run on pure ethanol rather than as additive to
fossil fuels), in the USA its corn and across Europe it’s predominantly wheat
and barley. The Philippines have mandated a 10% ethanol mix in gasoline since
2007. And biodiesel—a diesel-like fuel commonly made from palm oil—is
generally available in Europe.
On the face of it, biofuels look like a
great solution. Unfortunately, it's not so simple. The process of growing the
crops, making fertilizers and pesticides, and processing the plants into fuel
consumes a lot of energy. It's so much energy that there is debate about
whether ethanol from corn actually provides more energy than is required to
grow and process it. Also, because much of the energy used in production comes
from coal and natural gas, biofuels don't replace as much oil as they use.
For the future, many think a better way
of making biofuels will be from grasses and saplings, which contain more
cellulose(it could be more efficient than current biofuels, and emit less carbon
dioxide). Cellulose is the tough material that makes up plants' cell walls, and
most of the weight of a plant is cellulose.
National policy on Bio-fuels.
Renewable energy resources are
indigenous, non-polluting and virtually inexhaustible. India is endowed with
abundant renewable energy resources. Therefore, their use should be encouraged
in every possible way. India’s energy security would remain vulnerable until
alternative fuels to substitute/supplement petro-based fuels are developed
based on indigenously produced
renewablefeedstocks. In biofuels, the country has a ray of hope in
providing energy security.
Biofuels are derived from renewable
bio-mass resources and, therefore, provide a strategic advantage to promote
sustainable development and to supplement conventional energy sources in
meeting the rapidly increasing requirements for transportation fuels associated
with high economic growth, as well as in meeting the energy needs of India’s
vast rural population & creating new employment opportunities.
The National Policy on Bio-fuels and its
implementation has been approved by the Union Cabinet(2008). The Indian
approach to bio-fuels is based solely on non-food feed stocks to be
raised on degraded or wastelands that are not suited to agriculture, thus
avoiding a possible conflict of fuel vs. food security.
The
salient features of the National Policy on Bio-fuels are:-
1. Bio-diesel production will be
taken up from non-edible oil seeds(400 species of trees in the Country) in
waste /degraded / marginal lands. Bio-diesel plantations on community /
Government / forest waste lands would be encouraged while plantation in fertile
irrigated lands would not be encouraged. The focus would be on indigenous
production of bio-diesel feedstock and import of Free Fatty Acid (FFA) based
such as oil, palm etc. would not be permitted.
2. An indicative target of 20%
blending of bio-fuels, both for bio-diesel and bio-ethanol, by 2017 has been
proposed.
3·Minimum Support Price (MSP) for
non-edible oil seeds would be announced with periodic revision to provide fair
price to the growers. Minimum Purchase Price (MPP) for purchase of bio-ethanol
and bio-diesel would be announced with periodic revision.
4. Employment provided in
plantations of trees and shrub bearing non-edible oilseeds will be made
eligible for coverage under the National Rural Employment Guarantee Programme.
5·Major thrust will be given to
research, development and demonstration with focus on plantations, processing
and production of bio-fuels, including Second Generation Bio-fuels.
6.In view of the current direct
and indirect subsidies to fossil fuels and distortions in energy pricing, a
level playing field is necessary for accelerated development and utilization of
biofuels to subserve the Policy objectives. Financial incentives, including
subsidies and grants, may be considered for second generation bio-fuels. If it
becomes necessary, a National Bio-fuel Fund could be considered.
7·The National Biofuel Policy
envisages that bio-fuels, namely, bio-diesel and bio-ethanol may be brought
under the ambit of “Declared Goods” by the Government to ensure unrestricted
movement of bio-fuels within and outside the States. It is also stated in
the Policy that no taxes and duties should be levied on bio-diesel &
bio-ethanol.
8·A
National Biofuel Coordination Committee, headed by the Prime
Minister, will be set up to provide policy guidance and coordination.
9· A Biofuel Steering
Committee, chaired by Cabinet Secretary, will be set up to oversee
implementation of the Policy.
10.The responsibility of storage,
distribution and marketing of biofuels
would rest with OMCs. This shall be
carried out through their existing storage and distribution infrastructure and
marketing networks, which may be suitably modified or upgraded to meet
the requirements for biofuels.
11.Plantation of non-edible oil
bearing plants, the setting up of oil expelling/extraction and processing units
for production of bio-diesel and creation of any new infrastructure for storage and distribution would be declared as
a priority sector for the purposes of lending by financial institutions and
banks. National Bank of Agriculture and Rural Development would provide re-financing towards loans to farmers for plantations. Indian
Renewable Energy Development Agency, small industries Development Bank of
India, commercial banks would be
actively involved in providing finance for various activities under the entire
biofuel value chain, at different levels.
12.Investments and joint ventures
in the biofuel sector are proposed to be encouraged. Biofuel technologies and projects would be allowed 100% foreign
equity through automatic approval route to attract Foreign Direct Investment would not be open for FDI participation.
13.Import of biofuels would only be permitted to the
extent necessary, and will be decided
by the National Biofuel
Coordination Committee proposed under
this Policy. Duties and taxes would be
levied on the imports so as to ensure that
indigenously produced biofuels are not costlier than the imported
biofuels. Import of Free Fatty Acid will not be permitted for production of
biofuels. Export of biofuels would only
be permitted after meeting the domestic requirements and would
be decided by the National
Biofuel Coordination Committee.
--The Ministry of New & Renewable
Energy has been designated as the co-ordinating Ministry for biofuel
development and utilization while specific roles have been assigned to other
concerned Ministries. In order to enable the Ministry of New & Renewable
Energy to effectively carry out its role as the coordinating Ministry for the
National Biofuel Progamme, it will be necessary for it to be suitably
strengthened through augmentation of its manpower with the flexibility of
hiring external professional manpower and services.
An Indo-US MoU has been signed
on biofuels with focus on joint R&D, particularly on second
generation biofuels such as, cellulosic ethanol and algal biodiesel.
Another initiative with research institutes and industry is on for development
of high efficiency engines for use of SVO(straight vegetable oil) for
stationary applications.
--(Jan 2013)The government having
cleared the import of the commodity, the public sector oil marketing companies
were reported to be moving jointly to float a Rs. 3,500-crore global tender to
source ethanol.
The annual requirement is estimated to be about 1,000 million litres for a
pan-India roll-out of 5 per cent blended petrol, which is already available in
some States. 5% blending of ethanol with gasoline has already been taken up by the Oil
Marketing Companies 20 States and 4 Union Territories. 10% mandatory blending of ethanol with gasoline
is to become effective from October, 2008 in these States. countries
like the United States now have established ‘doping’ programmes that involve up
to 20 per cent ethanol.
India stands to save a huge amount of
foreign exchange through the blending programme, provided it gets ethanol at a
viable price. There is also an environment & economical dividend as India’s
ethanol source is sugarcane unlike U.S.'s(food crops so no increase in food
prices). It ought to follow the example of Brazil, 51 per cent of whose fuel market is
made up by sugar-based ethanol, making it the leading biofuel exporter and the
second biggest producer after the U.S.
Domestic ethanol consumption rose by 4.5
per cent to 2.08 billion litres(production- 2.1 billion litres in 2012).
However, only an estimated 400 million litres were available to be blended with
petrol. The
liquor industry’s insatiable appetite for ethanol is responsible, and powerful
interests that push for better price yields are having a field day. So
if imports are allowed then pricing formula should be mutually beneficial to
all in long term otherwise the government ought to consider an intervention to
mandatorily channel a certain percentage of indigenously produced ethanol for a
requirement that is clearly in the national interest. States should also
cooperate by easing regulations. Meanwhile, sufficient lead time should be given to the auto
industry to carry out engine and other modifications to make vehicles
compatible with still higher levels of blended fuel.
--We(Virgin Atlantic) were the first
airline to take a bio-fuel flightwhen everyone was saying it couldn't
be done. We need to make sure that there are global protocols on how the
industry develops bio-fuels such as by ensuring that we don't cut down forests,
don't displace food crops and don't use scarce water resources.
New Zealand bio-fuel company, Lanzatech,
take waste gases from industrial processes which are bad for the environment,
reprocess them to initially make ethanol and then jet fuel. There is an
interesting statistic. If you just fitted these Lanzatech scrubbers on 65 per cent of
the world's steel mills, you will produce 15 billion gallons of jet fuel a year
and that's over 20 per cent of current global jet fuel consumption. Its
early days yet and the trial plants are working but we are looking to fix some
industrial scale units. You could well see our Delhi and Shanghai flights
flying on bio-fuel in the next three years
--(oct 2012)The European Union
(EU) has announced on October 17 that the amount of biofuels that will be
required to make up the transportation energy mix by 2020 has been halved from
10 per cent to 5 per cent therefore effectively revises the Renewable Energy
Directive (RED), 2009.
A study conducted in 2009-2012 by the EU
found that greenhouse gas emissions were on the rise because of conversion of
agricultural land for planting first-generation biofuel crops(such as corn,
sugarcane, and potato). It also became known that large quantities of carbon
stock had been released into the atmosphere because of forest clearance and
peatland-draining.
The EU is now incentivising
second-generation biofuels — manufactured from crop residues such as organic
waste, algae, and woody materials — that do not interfere with food-production. The RED also required that biofuels which replace
fossil fuels be at least 35 per cent more efficient. The EU has now made
more stringent; biofuels
should be at least 50 per cent more efficient by 2017, and 60 per cent more
efficient after 2020. Research on high-performance biofuels is still
nascent. Focus is more on extracting fuel rather than efficiency from available
stock. The announcement also affirms that till 2020, no major changes will be effected in
the biofuels sector, and post-2020, only second-generation biofuels will be
supported, paving the way for sustained and focused development of
high-efficiency, low-emission alternatives to fossil fuels.
--Like the EU, the U.S. too has a
biofuel-consumption target set for 2022. However, a U.S. National Research
Council report released on October 24 found that if algal biofuels,
second-generation fluids whose energy capacity lies between petrol’s and
diesel’s, have to constitute as much as 5 per cent of the country’s alternate
energy mix, “unsustainable demands” would be placed on “energy, water and
nutrients.”
--(Sep 2013)Oil import is the heaviest burden on India’s foreign
exchange, at $144 billion last year.
Brazil has already done it successfully,
reducing petrol consumption by 30 per cent. Brazil is the global leader with 16
million of the world’s total 27 million flexi-fuel vehicles in December 2011.
The Brazilians are now moving into cellulosic ethanol technology, which uses
waste material and bagasse from sugar mills. The use of fuel ethanol has
created a synergy between the agriculture and energy sectors and a win-win for
farmers, industry and government. It has also improved the quality of air in
Brazil’s cities as ethanol is less polluting than petrol.
Oil crisis
How did Brazil do it? In 1974, hurt by
the oil crisis, the government brought together all stakeholders — sugar cane
farmers, sugar mills, car manufacturers and oil companies besides the
ministries of agriculture, industry and energy — and formulated a policy that
would ensure energy independence. Today, fuel ethanol is the centrepiece of
Brazil’s energy, agricultural and industrial strategy and Brazil is a role
model for the world.
Brazil is working quietly to create a
global ethanol market with standardisation of specifications and market
mechanisms in collaboration with the U.S. &encouragind and collaborating
with others. India has the potential to replicate the success of Brazil; we are
the second largest producer of sugar cane in the world. And the risk and
investment involved in ethanol production is far lower than in oil exploration
and production.
Hostage to policy
Ethanol has been considered before. In
2006, the government of India launched a programme of five per cent mandatory
ethanol blending. But oil companies offer unattractive prices to local ethanol
suppliers even as they pay top dollar for foreign oil supplies. The ethanol
producers naturally prefer the better prices offered by chemical and alcohol
companies as well as foreign importers.
The mandatory blending should be
increased to 10 per cent immediately, with the target of 20 per cent in the
next three years. New Delhi can compel the oil companies to invest in ethanol
production, so they have a stake in its development. The car manufacturers too
must be brought on board to modify the engines. Some foreign car makers in
India such as Ford, GM, Volkswagen, Honda, Toyota, Renault and Fiat are already
producing flexi-fuel cars in Brazil, and can easily do so in and for India.
Benefits
Ethanol will help farmers sustain their
income during the cyclical bumper harvests and their lower sugar prices, as is
the prevailing situation this year. India will reduce its trade deficit and
foreign exchange outflow. And there will be less pollution. Most importantly,
fuel ethanol will be a sustainable, long term, India-centric solution.
