While policy momentum behind biofuels has sputtered in recent months due in part to a slumping economy, indirect land use change debates, and life cycle studies concluding that “green” fuels cause more greenhouse gas emissions than conventional fuels, using waste as a fuel feedstock represents a promising shortcut on the path to energy security.
Waste-to-fuel is nothing new, but it remains a vastly underdeveloped alternative despite being cheap, abundant, and according to the EPA, renewable. More recently, a convergence of environmental, economic, and energy factors have bolstered the development of increasingly innovative waste-to-energy solutions.

There’s a kernel of good to this story, if you care about climate change and high food prices.
Sure, ethanol has been a great example of how America can begin to overcome its dependency on foreign fossil fuels. But using a staple like corn to make the biofuel has driven up food prices and displaced other food crops.
Now comes the Obama administration, which has proposed new rules for renewable fuels, aimed at cutting carbon dioxide emissions. At the same time, he’s vowed to help prop up the corn ethanol industry with stimulus dollars, and commit stimulus funds to biofuel research.

As part of an ongoing effort to reduce US dependence on foreign oil and address the climate crisis by increasing the use of domestic renewable fuels, Secretary of Energy Chu announced Tuesday plans to provide $786.5 million in ARRA funding to accelerate advanced biofuels research and development, and to provide additional funding for commercial-scale biorefinery demonstration projects.
The funding is available through ARRA’s Research and Development program and will be awarded through competitive grants from the DOE’s Office of Energy Efficiency and Renewable Energy (EERE).

Last week I went to the World Bank’s Energy Week in DC. It was an exciting event in which the World Bank hosted “energy and finance industry executives, senior donor and developing country government officials, stakeholders and leading-edge thinkers of the energy sector”. Seminars discussed energy efficiency, rural electrification, alternative energy resources, and climate change. The Global Energy Assessment was an interesting topic discussed by US renewable energy trade organization and private sector. If you’ve been paying attention to renewable energy there was nothing new, except the passion to engage the emerging markets.

Can you make lemonade from algae?
Figuratively, yes. A bunch of students from the University of Michigan and Michigan State University have a business plan to use algae to treat wastewater and make biofuels.
It’s a double play, like taking lemons and making a cool, refreshing drink. Or maybe even a three-pointer, since these are rival schools.
The students, calling themselves Team Algal Scientific, were recently awarded the first-ever Clean Energy Prize from U of M and DTE Energy.

No, it’s not the latest CD from Verve, it’s the latest rumble from industry groups and states: Raise the percentage of ethanol blended into unleaded gasoline.
The current cap is 10 percent. An ethanol trade group called Growth Energy has formally requested an increase to 15 percent, saying it will create more than 100,000 jobs and pump more than $24 billion into the economy, Reuters reports. There’s also the added benefit of increasing the demand for ethanol by 6 billion gallons a year, MSNBC says.
The U.S. Environmental Protection Agency is studying whether a higher blend would harm older cars. Some newer vehicles are designed to run on E-85 (an 85 percent blend).

Fuel cells and hydrogen were the buzz for years in U.S. automotive industry, until foreign competitors began making waves with hybrids.
Problems with the H included the high cost of infrastructure and the fossil-fuel energy needed to make hydrogen stations work.
That could change if new research on enzymes is realized. A team of scientists from Virginia Tech, Oak Ridge National Lab and the University of Georgia has developed a way of producing hydrogen gas by combining enzymes and cellulosic materials from non-food sources with good old water, according to a news release.

Came across a report from the Congressional Research Service (pdf) on biofuels. Dated Jan. 5, 2009, it’s a decent summary of federal incentives (pre-stimulus).

Some numbers: There are 24 U.S. programs that support biofuels, mostly ethanol and biodiesel. They were established over the last 28 years and are administered by five government agencies: Environmental Protection, Agriculture, Energy, IRS, and Customs and Border Protection.
If policy drives business, it looks like there are 101 reasons to develop cellulosic biofuels (from plant waste rather than people food). There’s a $1.01 per gallon credit from the IRS for producers.
The appendix has a summary by agency. Something to chew on.
The Pew Center also has a guide to state incentives.

Exciting news on the cellulosic ethanol front. The promise of next-generation biofuels is moving from the lab to the factory.
BP has announced a joint venture with Verenium to make cellulosic ethanol from grass and other non-edible plants.

Exit up ahead: A University of Minnesota study has concluded that corn-based ethanol is no better than gasoline.
The Star Tribune says ethanol may even be a bigger polluter, when it comes to greenhouse gas emissions and particulate matter. Cellulosic ethanol made from switchgrass and other plant materials is far better for human health, the scientists say.
But the Renewable Fuels Association claims the study is flawed. Among other things, it assumes that grassland will be taken out of the federal Conservation Reserve Program to make more corn-based ethanol. The RFA says most of the increase in corn production in the U.S. has been through higher yields rather than conversion, and there’s no peer-reviewed evidence for the study’s methods. (see the pdf).
