  • Story Text: Can algae save the world -- again? Algae, microscopic green plants, cleaned up the earth's atmosphere millions of years ago and scientists hope they can do it again, helping removing greenhouse gases and also creating new oil reserves.
    In the distant past, algae helped turn the earth's then inhospitable atmosphere into one that could support modern life through photosynthesis -- which plants use to turn carbon dioxide and sunlight into sugars and oxygen. Some of the algae sank to sea or lake beds and slowly became oil.
    "All we're doing is turning the clock back," says Steve Skill, a biochemist at the Plymouth Marine Laboratory. "Nature has done this many millions of years ago in producing the crude oil we're burning today. So as far as nature is concerned this is nothing new," he said.
    The race is now on to find economic ways to turn algae, one of the planet's oldest life forms, into vegetable oil that in turn can be made into biodiesel, jet fuel, other fuels and other plastic products.
    "So we are harvesting sunshine directly using algae, then we are extracting that stored energy in the form of oil from the alga and then using that to make fuels other non-petroleum based products," Skill said.
    He predicted that industry will be cultivating algae in viable quantities for commercial oil production with a decade. Such fuels are considered to be net carbon neutral because the algae absorb greenhouse gases when they grow.
    Many companies are working on algae and biofuels including U.S. groups Sapphire Energy, OriginOil <OOIL.OB>, BioCentric Energy and PetroAlgae <PALG.OB>. Among uses, Japan Airlines had a test flight last month with a jet fuel and biofuels blend including algae oils. Brazil's MPX Energia plans to trap 10-15 percent of carbon emissions from a coal-fired power plant by feeding them to algae when it starts in 2011.
    Plymouth Marine Laboratory say they are taking what we already know about algae in the world's oceans and applying it to biotechnology, an approach which differs from much of the commercial research underway - where some claims about the possibilities of algal biofuels are overstated, according to Dr Carole Llewellyn, a marine chemist.
    "They (algae) do have a lot of positive attributes but there are a lot of hurdles that have to be overcome before this becomes a commercial reality," said Dr Llewellyn.
    Cultivating crops on prime farmland to produce bio-diesel has been widely criticised for helping sustain higher food prices. But many strains of algae grow in sites otherwise uninhabited, from salt-water marshland to deserts. They can grow 20 to 30 times faster than food crops.
    Reasearch in Plymouth includes identifying which strains of algae will produce the most oil or absorb the most CO2 in differing growing mediums.
    Algae's requirement of a source of carbon dioxide has also stimulated interest from industrial plants which see the possibility of feeding algal beds with carbon-rich exhaust fumes from their power plants.
    Research into replacing petroleum based fuels and products with biodiesel from algae is not new. The U.S. government began funding research in the 1970s and only discontinued the programme in 1996 when it was reported that producing bio-diesel simply cost too much and would not become economic until oil prices rose to $40 a barrel.
    Prices for Brent crude on Tuesday were $46 a barrel.
