Dairy converts trucks to biogas power

A California Dairy is using biomethane from cattle manure to power two farm trucks.
GRAINNET News and Information for the Grain, Milling, Feed, Seed and BioFuels Industry: "Nationally, dairy cows could power about one million vehicles with clean-burning biomethane."

Plans to produce flex-fuel ethanol engine with better fuel economy

The British firm Ricardo expects to roll out a new engine design in 3-5 years that would run more efficiently on ethanol. They expect it to have only a 15% drop in fuel economy on ethanol, much better than the 30% drop experienced in most models today. This will make ethanol, such as E85, more cost-competitive and more attractive to consumers. The use of such engines in plug-in electric hybrids would create an attractive package in terms of fuel efficiency, low emmissions, and low cost of operation.
Ethanol stalled, but experts say it remains viable fuel option - Rebranding Michigan - Michigan Business Review – "It aims to leverage the higher octane and higher heat of vaporization elements of ethanol to increase fuel economy. It integrates direct injection technology, variable valve timing, exhaust gas recirculation and optimized ignition technology."

Direct Solar to Hydrogen Plant to be built in Australia

Water can be broken down into hydrogen and oxygen with electricity. This facility in Australia will use solar concentrators to directly heat water to 1000 degrees. At this level of heat a given amount of electricity can produce more than twice as much hydrogen in the electrolysis process. In essence, then, they are making hydrogen from direct solar energy (as opposed to solar electricity) by displacing some of the electricity needed for the electrolysis process.
Direct Solar to Hydrogen Plant Goes Up in Australia Hydrogen Cars and Vehicles: "Solar Systems of Hawthorne in Victoria, Australia is developing the country’s first and perhaps even the world’s first direct solar to hydrogen commercial power plant."

Ethanol from Idaho agricultural waste

Solving two problems at once can make a process more economically viable. In this case, it is waste management and fuel production.
ISU Headlines » Researchers seek to create ethanol from Idaho agricultural waste: "They are not exactly alchemists trying to turn lead into gold, but almost: researchers from Idaho’s three largest public universities are seeking to create ethanol from the Gem state’s agricultural waste.
And they have a realistic shot at converting potato, sugar beet and other agricultural waste – perhaps even cow manure – into a fuel that can run in your car.
