Does it run on biofuel?

  • 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

  • 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

10
THE 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

  • 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.

  • 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.

  • 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
  •  
  • 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?

24
I 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?
