A research team from Sandia National Laboratories is trying to reverse the combustion process and turn carbon dioxide into liquid fuel.

The process works something like this: concentrated solar power from a giant solar furnace is used to superheat a set of catalytic cobalt ferrite rings that, once activated, literally rip carbon dioxide (CO2) molecules apart. As a result, CO2 is transformed into carbon monoxide, which can be converted into methanol, jet fuel, or even gasoline.

Sounds a little too good to be true, but researchers say it works and claim a prototype facility will be completed by April.

The idea of recycling carbon dioxide is not new, but has generally been considered too difficult and expensive to be worth the effort. But with oil prices exceeding $100 per barrel and concerns about global warming mounting, researchers are increasingly motivated to investigate carbon recycling. Los Alamos Renewable Energy, for example, has developed a method of using CO2 to generate electricity and fuel.

Used-cooking-oil, the golden-brown waste product left over from making French-fries, doesn’t strike most of us as a particularly valuable commodity.

But recycled grease represents a source of cheap energy to some, one that can be converted to biodiesel or used directly as a substitute for diesel fuel. Having collected waste oil for both of these ends, I can tell you I’ve always had a nagging suspicion that one day the ‘free’ ride would come to a screeching halt. It just wasn’t clear how soon it would end.

Some parts of the country are now facing fierce competition over this generally unknown but ubiquitous local resource. The Associated Press has dubbed it the “Grease Wars”:

Recycled cooking oil has traditionally been sold for use in cattle feed and cosmetics. But the segment going to biofuels has grown in recent years to account for about 20 percent of the used oil market, said Tyson Keever, co-founder of Sequential Pacific Biofuels, the state’s largest manufacturer of biodiesel.

Portland’s oil peddlers are now fighting over grease worth as much as $1.20 a gallon. “You have processors now in the metro area who are looking at using that grease for biodiesel primarily,” said Mike McCallum, president and CEO of the Oregon Restaurant Association. “There are restaurants who are being solicited for the use of the grease and are getting some money for it.” The result in the long run may be more expensive biodiesel at the pump.

First world countries are addicted to their disposable, aka “landfill” diapers. According to Planet Trash, “Americans alone go through around 18 billion disposable diapers a year.” A Canadian company wants to turn all those dirty diapers into a cost-effective, diesel fuel.

Using the process of pyrolysis to convert diapers to diesel, a facility is going to be built in Montreal. Pyrolysis, also known as thermal cracking, involves heating the dirty diapers in a closed environment that lacks oxygen. This closed system does not produce any emissions. Luciano Piciacchia, an engineer and vice-president with Amec’s Quebec office, explains,

Then you’re bringing it to the next level which is breaking the carbon chains down … and (in the end) they will resemble the fuels which are what we’re going to end up producing.

The company plans to begin collecting soiled diapers from area hospitals. “One of the beauties of the diaper is that it is going to be a very consistent input,” compared to trying to make fuel from other kinds municipal waste.

The strange part of this story is, the plant never went into operation. As a matter of fact, it’s still under construction. Farmers who invested in the project have lost their money since the Chapter 11 filing creates a federal injunction prohibiting creditors from taking action against the company, Central Illinois Energy.

It’s taken five years to get the operation to this point, but the main contractor, Lurgi PSI, left the job site and cancelled all contracts on the grounds it wasn’t being paid. The Fulton County Clerk’s Office says more than $30 million in liens have been filed for unpaid invoices by contractors.

Attorney Barry Barash of Galesburg, IL, who is overseeing the bankruptcy, said there were several factors that lead to the action. Re-engineering costs affecting the contractor have been suggested, and the fact that Lurgi was allowed to spend on the project without limit.

Looking to buy your own algae biodiesel manufacturing plant?
You may be in luck.

AlgaeLink has developed the first made-to-order industrial algae production facility in the world.

Sure, we’ve all read 50 stories about algae biodiesel the panacea—the only biofuel that will make a serious dent in petroleum usage—but none of those stories have materialized yet. But the fact that commercially harvesting algae could [...]

Despite promises of imminent commercial viability and tremendous productivity, the development of algae cultivation for biofuel production has been painfully slow. Most of us following biofuel news have been frustrated by the sluggish pace of real progress.

GreenFuel Technologies has finally produced some results:

This summer, GreenFuel Technologies and Arizona Public Service Company (APS) were able to grow algae successfully at APS’ Redhawk natural gas power plant at levels 37 times higher than corn

"There’s no free lunch" is an old axiom that surfaces everytime I think something for nothing is coming my way. This time it’s ethanol, and you’re probably already aware that less corn is going to your table because more of it is going to fuel. So we’re paying for cleaner air everytime we buy products made from corn.

If a person pays attention, they can turn common situations into a positive energy saving message. That’s what today’s guest does very well with an interesting and informative website called Energy Boomer.

Right now, a uniquely modified pickup truck is making its way across the country. Starting from Detroit and heading to San Francisco, the vehicles developers are seeking to draw attention to an overlooked fuel alternative. The truck uses a special fuel, something widely available throughout the country, but until now, not widely considered as a fuel for transportation: the truck is carrying three tanks of ammonia in its bed. In addition

When I was a kid on the farm, tiptoeing through a barnyard was a way of life. It was something like playing hopscotch with cow pies. When spring came, it was time to clean out the barn, transfer the winter’s supply of manure, one pitchfork at a time, into a “honey wagon” and take it to the fields to be used as fertilizer. It amazed me how much there was, and until

I'm not that much of an automobile enthusiast. Despite my proximity to the Motor City, I don't pay constant attention to the latest twitches in the auto industry. I take the bus to work, and drive a car only occasionally, usually for errands or to shuttle the kids someplace. But I attended the GM ChallengeX event on behalf of EcoGeek.org and Green Options, and
