  • Algae require only sunlight, water and carbon dioxide to grow. They can quadruple in biomass in just one day. And, what's more, they suck up harmful pollutants such as nitrogen from waste water and carbon dioxide from power plants as they grow.  Some strains of algae contain over 50% oil and an average acre of algae grown today for food and pharmaceutical industries can yield around 19,000 litres of biodiesel, compared to just 265 litres for one acre of soya beans or 1,600 litres of ethanol for an acre of corn.

  • HySeries Drive plug-in hybrid. Electricity only for 25 miles (with a 336-volt lithium-ion battery pack). Serial hybrid, with the fuel cell (or think biofuel system) recharging the battery pack, not directly driving the wheels.

  • Renewables such as wind, solar and biofuels then start to look like fruits and vegetables: healthy components of a balanced diet, but not enough to live on, by themselves.

  • For this special report, PM crunched the numbers on the actual costs and performance of each major alternative fuel. Before we can debate national energy policy--or even decide which petroleum substitutes might make sense for our personal vehicles--we need to know how these things stack up in the real world.

  • Alternative fuels aren't a perfect alternative to gasoline. They have less energy than gas and cost more; it's improbable that production will be ramped up for more than a fraction of America's vehicles; they have corrosive effects on normal fuel systems; and it's not certain we'll get the technology to work soon.

    The whole idea stinks. But generating heat and power from livestock manure is appealing. The compost is placed into an oxygen-free machine that separates the methane gas and then uses it to create electricity to power farms or transport over the grid.

  • "Do I hear 10 per cent? Yes, sir. What's that? Carburants will contain 10 per cent biofuel by 2020?  Oh, that's very good! Any advance on 10 per cent? Do I hear 20 per cent? Don't all bid at once. My! I see three hands. Yes, madam, you first. 20 per cent of all energy to be derived from renewable sources? I'm sorry? Excluding nuclear? I see. Mustn't make it too easy.

    Kline, a worldwide consulting and research firm, yesterday announced the launch of a new line of research studies called Kline FlashPoint. The first report, "Biodiesel: Helping to Solve the Oil Crisis, but at What Cost?" offers a strategic overview and assessment of the complex global biodiesel market and provides recommendations for companies that are evaluating their options for participation.

  • Through a chemical reaction, the captured gases from the box would be fed to algae, which would then be crushed to produce a bio-oil. This extract can be converted to produce a biodiesel almost identical to normal diesel.

    Transport group Arriva is trialling B20 biodiesel - a blend of normal and plant-derived diesel - for the first time on its buses. The 75 buses in the innovative trial will run from Arriva's Blyth Garage in Northumberland and carry around 130,000 passengers every week. Minimal engineering changes will be required to the fleet as part of the scheme. The company is aiming to reduce total carbon emissions by around 14 per cent by using Fatty Acid Methyl Ester (FAME) as a 20 per cent blend. The FAME will predominantly be a mixture of sustainable soya products, along with used cooking oil and tallow.

    Picture a liquid fuel that is derived from the same feedstocks as cellulosic ethanol (switchgrass, sugar cane, corn stover) but contains 50% more energetic content and is made via a process that uses 65% less energy.

    According to researchers from the Carnegie Institution, the University of California, Merced and Stanford University, converting biomass to electricity delivers 80% more miles per acre of crops and doubles the potential for greenhouse gas offsets.
