2Does it run on biofuel?
3- BIOFUELS WHY?
- Transport fuel usage and emissions growing too
fast - Developed World response to worries about oil
supplies - Token effort to reduce carbon emissions
- Avoid confronting car manufacturers about
efficiency? - Keeping the US farmers happy?
- A panic move by politicians to be seen to be
doing something? - A false belief among politicians that there
must be a technical solution to climate change
4- BIOFUELS GOVERNMENT POSITION
- The EU Biofuels Directive's target - 5.75 per
cent of fuels sold in the EU should be biofuels
by 2010, and 10 percent by 2020. - EU Energy Policy announcements this month allow
state aid to be given to biofuel production. - The UK's RTFO target - five per cent of fuels,
by volume, sold in the UK should come from
biofuels by 2010. From April 2008, petrol and
diesel must contain 2.5 biofuel. - 7.5 billion gallons of ethanol mandated by the
USA 2005 Energy Bill by 2012. The Energy
Independence and Security Act of 2007 requires
fuel producers to use at least 36 billion gallons
of biofuel in 2022 - Â

6- BIOFUELS THE ISSUES
- Questionable if they save greenhouse gases
- Doubts over the energy balance
- Disruptions to an already strained global
agricultural system - Increased demands on water supplies, fears of
topsoil erosion - A cause of deforestation and other land use
change - Habitat and biodiversity destruction
- Social upheaval impacting indigenous peoples
- Second generation technology for ethanol yet to
be proven, may rely on genetic modification.
Algae look promising - Is there land and water to grow enough fuel to
make a difference? - Another case of the developed world exporting the
unwanted consequences of our lifestyles?
7- BIOFUELS THE BAD BITS
- Palm oil 8 per cent of global CO2 emissions is
caused by draining and deforesting peat lands in
South East Asia, largely for oil palm
plantations. Land used is often taken from
indigenous peoples. - Soya South America tropical rainforest is
cleared, wiping out 80-100 per cent of the
biodiversity. Much soya is genetically modified. - Sugar Cane Brazil, the biggest producer of
sugar cane has cleared huge areas of savannah
lands, destroying much biodiversity. Labour
conditions on sugar cane plantations are often
appalling. - Oil seed rape High fertiliser input means that
the EUs preferred biofuel crop may be up to 70
per cent worse for the climate than fossil fuels. - Maize The big incentives to grow maize for
biofuel in the USA have been blamed for rising
corn prices. Production of cereals for beef
cattle is displaced from US to other countries.
8- BIOFUELS GHG EMISSIONS
- The production of biofuels is not GHG-free
- Diesel for tractors, heat for refineries, diesel
for ships and trucks etc to move raw materials
and finished product all produce CO2 - No-one knows for certain if these outweigh the
benefits.
- But fertiliser use probably tips the balance.
- Maize and rapeseed yields are typically enhanced
by using nitrogen fertilisers in bulk. Nitrous
oxides are then released to the atmosphere. - Paul J. Crutzen, 1995 Nobel prize winner for
chemistry, said in 2007 - Biodiesel produced from rapeseed can result in
up to 70 percent more greenhouse gas emissions
than burning fossil fuel diesel. Ethanol made
from maize results in 50 percent more emissions. - (nitrous oxide reflects 300 times as much heat as
CO2)
9- BIOFUELS LAND USE CHANGE IMPACTS
- Professors Alex Farrell and Michael O'Hare from
the University of California at Berkeley in Jan
2008 - If corn grown on conservation reserve program
land is used for ethanol, total lifecycle
emissions, including indirect LUC, are - 2.4 x gasoline
- If replacing corn used for ethanol causes
tropical deforestation, total lifecycle
emissions, including indirect LUC, are - Over 6 x gasolineRenewable diesel using palm
oil has total lifecycle emissions,including
indirect LUC, of - 2.3 x diesel
10THE EFFECT OF LAND USE CHANGES ON GHG EMISSIONS
- Brazilian officials said Amazon destruction
surged during the last five months of 2007 - Deforestation rose from 94 square miles in
August to 366 square miles in December

13- BIOFUELS ENERGY BALANCE
- Energy is needed to grow plants and turn them
into fuels - If greater than the energy produced by fuel
there is a negative energy balance - Doubts that all biofuels give a positive balance
or a worthwhile positive balance
- David Pimentel and Tad Patzek concluded that all
crops converted using current processing methods
gave a negative energy balance - return is 0.778 unit of energy in maize ethanol,
- 0.688 unit in switchgrass ethanol,
- 0.636 unit in wood ethanol
- 0.534 unit in soya bean biodiesel.

15- BIOFUELS SUSTAINABILITY CRITERIA
- European Commissions position (Jan 2008)
- Land use - old forest with no or limited human
intervention cannot be used for biofuels
cultivation, nor can 'highly biodiverse
grasslands', or lands with a 'high carbon stock'
like wetlands or 'pristine peatlands - CO2 impact - the overall greenhouse gas (GHG)
savings from biofuels production must be at least
35 in order for cultivation to be considered
sustainable. (EuropaBio has challenged this) - Consultation showed general support for such
criteria from most respondents, with many
proposing further reinforcements to the scheme. - Rewards for diversifying the feedstocks such as
ligno-cellulosic material for the production of
second generation biofuels.
But no consideration of the impact of Biofuels on
food production, water supplies and on indigenous
peoples welfare
16- BIOFUELS THE GOOD BITS (?) ALGAE
- Biofuel yields gallons/acre
- Corns 50-60
- Soya 48
- Oil Palm 635
- Algae 5,000 - 10,000 gallon/acre
- Algae is a single celled plant - highest uptake
of CO2 - Can double its mass in a day harvest daily not
annually - Can use contaminated water supplies and
infertile land - Power plant flue gases used to promote growth
recover 30 of waste heat into new fuel,
absorbing CO2 and NOx to mitigate climate change - Suitable for making ethanol, diesel, and other
hydrocarbons, including biomass for burning - US companies Solazyme and GreenFuel actively
developing
17- BIOFUELS THE GOOD BITS (?) CELLULOSE
- Plants contain starches (sugars), cellulose,
proteins and lignin. Starches / sugars are used
for first generation biofuels - Second generation biofuels are made from
cellulose and lignin - Cellulose and lignin are structural by nature
tough and harder to break down than starches - Can use non-food crops like switchgrass as well
as food-crop waste and wood waste - More obvious positive net energy balance than
corn to ethanol (five times better) - Cellulosic biomass can produce methanol,
dimethyl ether, Fisher Tropsch diesel, synthetic
gasoline, hydrogen. Ethanol is almost always the
worst possible choice due to pipeline problems. - Conversion processes can be either
thermo-chemical or biological
18- BIOFUELS THE GOOD BITS (?) CELLULOSE
- Thermo-chemical process
- Heat, pressure and steam turn biomass into
Synthetic Gas Syngas - Chemical reaction with catalyst converts Syngas
into alcohols - Alcohols separated by distillation
- No yeasts, microbes or GMO
- Biological methods
- Cellulase / Yeast processes
- Thermophilic bacteria look a better bet
- Possible use of GMO plant variants to increase
yields - Coskata (US)) has just announced a process using
bacteria and existing gasification technology to
generate 99.7 pure ethanol, plus water.

20- FOOD PRODUCTION IS JUST KEEPING PACE WITH
POPULATION - In 2006 food production worldwide rose by less
than 1. - Per capita food production fell by 0.2 - the
first such decline since 1993. - Cereal production fell for the second
consecutive year. - Wheat output was down 5 and coarse grains (e.g.
Maize) were down 3 , rice production was
virtually unchanged. - In Australia and USA cereal harvests fell by 60
and 7 respectively. The EU, Canada, Argentina
and South Africa also declined. - In the period 1996 to 2006
- Total world agricultural production increased by
2.2 pa - But cereals grew by just 7.4 over the same
period - Global population grew 13.5
21- BIOFUELS A PROBLEM WHO SAYS?
- Lester Brown the US is generating global food
insecurity on a scale never seen before. In a
misguided effort to reduce its oil insecurity by
converting its grain into fuel for cars, the
United States is driving up food prices
worldwide. - Hilary Benn We know from the evidence that we
have currently we have some types - ethanol from
corn which is even worse than the petrol it is
meant to be replacing - Chris GoodallYour 2,000 calories of food a day
is worth about 3p to a wheat farmer, but about
10p to a petrol retailer - Jean Ziegler, UN special rapporteur on Food
the growing practice of turning crops into
biofuel is a crime against humanity - European Commission Joint Research Centre
"uncertainty is too great to say whether the EU
10 percent biofuel target will save greenhouse
gas or not."
22- BIOFUELS A PROBLEM WHO SAYS?
- EU Environment Commissioner Dimas the
environmental and social problems caused by
agrofuels are bigger than we thought - The International Water Management Institute
"Ambitious plans in China and India to greatly
increase domestic production of biofuels will put
greater stress on these countries' water
supplies, seriously undermining their ability to
meet future food and feed demands." - Biruté Galdikas, primate scientist "People who
buy palm oil have orangutan blood on their
hands." - Rupert Furness, UK RTFO Programme Director We
agree that biofuels are not a 'silver bullet.
The Government is determined to support only
those biofuels which deliver genuine
environmental benefits - Roger Kemp, professor of engineering at
Lancaster University We would need to plant a
land area twice the size of Britain to get enough
biofuel crops to halve our emissions
23- OUR FOSSIL FUEL LEGACY
- Â
- Carboniferous period was 280 to 345 million
years ago - In this 65 million year period, the remains of
plants and animals were converted to oil,
coal and gas - We started using them in earnest only about 200
years ago. - If we carry on using them at current
(increasing) rates, we might burn most of them in
1000 years. - Effectively we burn many thousands of years
worth of fossilised biomass every year
- Can we really grow 5 or 10 of our transport
fuel needs every year without any impacts on the
planet?
24I don't understand bus lanes. Why do poor people
have to get to places quicker than I do?"
25- ALTERNATIVES?
- Travel less rethink lifestyles and town
planning - More efficient cars (the 7.5 bn gallons of
ethanol mandated by the US 2005 Energy Bill by
2012 could be compensated by an increase of car
mileage by just one mile per gallon.) - Greater use of LPG for cars 15 less CO2 than
petrol - Electric cars huge capital investment, too
expensive for China / India? (although G-Wizz
comes from India) - Better public transport
- Grow your own food
- AND?
