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 – MLive.com: "It aims to leverage the higher octane and higher heat of vaporization elements of ethanol to increase fuel economy.

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."

Bateria increases poplar biomass yield up to 50%

Poplar is being researched as a promising crop for cellulosic ethanol production. These trees grow very fast, even on marginal land unsuitable for most types of food production. It has long been known that many plants rely on organisms such as fingi and bacteria to optimize uptake of nutrients. The research described in the linked article seeks to optimize this relationship by innoculating with the most desireable types of bacteria. This technique might have applications for food crops as well. Farmers already innoculate legume crops on a routine basis to improve nitrogen fixation from the air. Other types of innoculation might be a good way to unlock the potential of nutrients found in the soil, but in a form that is unavailable to most plants.

Cornell technology makes small scale biogas more feasible

Biogas can be made on a farm or landfill scale with simple technology. Removing the hydrogen sulfide, however, has been a more complicated process and not suited to small scale. It is toxic and needs to be removed for many applications and to reduce pollution. Scientists at Cornell have developed a small scale solution for removing hydrogen sulfide that is suitable for farms and other locations outside the large refineries. Biogas than then be used in properly equipped engines for electricity generation, transportation, and other work.

Cornell Chronicle: Cornell technology makes biogas greener: "Cornell plant scientists have invented a new method that uses manure and other farm byproducts to remove toxic hydrogen sulfide from biogas -- a renewable energy source derived from the breakdown of animal waste."

Scaling up biochar and pyrolysis for energy and agriculture

Pyrolysis means heating biomass in an oxygen-deprived environment. The result is pyrolysis oil, syngas (can be burned to make electricity) and biochar (a promising fertilizer). If it can be sacaled up, it could be an important solution for food production, greenhouse gas reduction, and clean energy production.
Carbon Sequestration, Agriculture, and Charcoal - Can Biochar Stop Global Warming? - Popular Mechanics: "Biochar goes beyond this, directly removing carbon dioxide from the atmosphere by stimulating plant growth as well as storing the carbon from decomposing plants in the soil as well as those that were burned to make it for as long as 5,000 years."

Interactions between ethanol, oil, and food prices

With the plummetting oil and food prices around the glode, we now have data needed in order to analyze what effect ethanol truly has on food prices. As the article below points out, food prices are tied more to oil prices than anything else. Ethanol production continues to expand even as food prices fall due to lower oil prices. All this should promt us to develop more regionalized and localized sustainable food systems that are less reliant on oil (fossil fuel) inputs.
Fact vs. Fiction on Food vs. Fuel - International Analyst Network: "At the height of the oil crisis, ethanol was responsible for keeping the price of oil 15% lower than where it would otherwise have been. This means that as vexing as some find annual ethanol subsidies of roughly $5.6 billion, the use of ethanol saved the U.S. economy in 2008 roughly ten-times that amount which otherwise would have ended up in the coffers of foreign oil-exporting countries - many of them hostile to us."

Saltwater Crops May Be Key to Solving Earth's Land Crunch

Certain plants can be grown on land with a high salt concentration. Some of them could produce high biomass yields for cellulosic ethanol production. Most food crops cannot be grown on these soils, so they are largely under-utilized for farming.
Food vs. Fuel: Saltwater Crops May Be Key to Solving Earth's Land Crunch Wired Science from Wired.com: "His team's report for the agency estimates that salt-loving crops could be used to produce 1.5 billion barrels of ethanol annually on a swath of new agricultural land almost five times the size of Texas."
