Texas A&M University Exposes Algae’s Secret Fossil Fuel Stash

Texas A&M researchers have discovered a strain of algae that directly produces petroleum type oilIn the search for a high efficiency algae biofuel, a team of researchers lead by Texas A&M University has been delving into the inner workings of the Botryococcus braunii green algae, and they have discovered a direct connection between the algae and deposits of  petroleum and coal.  The discovery is significant because it could lead to the development of new strains of algae that produce the highest yield of biofuel compared to the amount of space needed to raise them.

Biofuel from algae and other plants is on the verge of mainstreaming as a form of renewable energy, but in terms of long term sustainability one sticking point has been the amount of land needed to raise biofuel crops.  Texas A&M’s finding raises the possibility of creating a viable platform for small-scale algae biofuel farming on brownfields and other underused land, or even in (or on top of) reclaimed buildings — which in turn would help create another opportunity to invest in green jobs.

Money Doesn’t Grow on Trees, but Biofuel Does

The University of Maryland and Bowie State University have received a $3.2 million grant from teh National Science Foundation to develop poplars for biofuelThe poplar tree has entered the crowded field of sustainable biofuel crops, and now it seems that China, Israel and the U.S. are racing to tap into its potential.  Poplars have a couple of big advantages over conventional biofuel crops, especially food crops like soy and corn.  For one thing, raising poplars is potentially more fuel efficient and generates a lower carbon footprint than annual food crops.  Depending on the growing conditions poplars don’t need as much pest control or soil enhancement, and they don’t necessarily need to be harvested each year – cut them back and they just keep growing.  Also, a  properly managed biofuel woodland can be part of a viable wildlife habitat, and could potentially coexist with human populations or recreation areas.

One roadblock is the slow growth rate of poplars relative to nonfood biofuel darlings like crambe and camlina.  That may not be a factor much longer.  Last fall an Israel-China research partnership was formed to develop new poplar variants for biofuel production in China.  And here in the U.S., the National Science Foundation has just announced a $3.2 million grant for the University of Maryland and Bowie State University to create new high-yield poplars for biofuel.

A Sustainble Recipe for Biofuel: Ethanol from Orange Peels and Tobacco

University of Florida researcher develops biofuel from oranges and tobacco enzymesCorn has been flaming out as a biofuel crop, and taking its place is a regular fruit salad of non-food and waste food alternatives.  The latest up and and comer is being developed by researcher Henry Daniell of the University of Central Florida, who naturally turned to oranges for his biofuel inspiration, with a new method for producing ethanol.

The fact that Florida is swimming in oranges illustrates the unfolding potential of the biofuel industry.  In contrast to fossil fuels, which are often shipped long distances to their point of use, biofuel production can be tailored to take advantage of local resources, whether it’s biofuel from unmarketable watermelons, algae, carbon monoxide harvested from factory emissions, or even biofuel from microbes and sunlight.  As for the connection between biofuel and tobacco, that’s the “secret ingredient” behind Daniell’s success.

British Airways To Source Jet Fuel Produced From London’s Municipal Waste

British Airways has announced plans to source a part of its fuel supplies from waste municipal waste to fuel plant. The company plans to procure 16 million gallons of green jet fuel annually from the Solena plant that would come up in London.

The plant which is expected to come online in 2014 would convert 50,000 tonnes of municipal waste into jet-grade fuel. The volume of fuel supplied initially would be 2 percent of the total fuel consumption of British Airways. This would cut down on the carbon emissions that is generated due to the conventional jet fuel, kerosene.

British Airways aims to obtain 10 percent of its jet fuel waste-to-energy processes.

Waste to energy process provides a three pronged advantage. One, it helps in the management of the ever increasing waste in the cities, two, it converts the methane (an efficient fuel and a greenhouse gas) which is produce from the decomposition of municipal waste and, third, its use results in reduction in carbon emissions.

One Giant Step Closer to Fuel-from-Sunlight by Joule Biotechnologies

Joule Biotechnologies has moved closer to constructing a pilot plant for producing ethanol and diesel from sunlightJoule Biotechnologies, Inc. has just announced that a lease agreement has been signed for a new facility in Leander, Texas, which will serve as a pilot plant to develop the company’s solar powered system for producing ethanol and other biofuels.  The energy efficient process is based on photosynthetic microorganisms and it operates without the use of conventional biomass or algae biofuel processes.

CleanTechnica and Gas 2.0 have been eagerly following Joule’s progress, and the company has already produced ethanol and diesel at a lab scale rate.  It plans to start ethanol production this year at the pilot plant, with diesel to follow early next year.  Once operating at full scale, the facility has  the potential to deliver at the rate of 25,000 gallons of ethanol per acre yearly, and 15,000 gallons of diesel.  That could be the tip of the iceberg, because the same process can also yield a variety of high-value chemicals in addition to biofuels.

FREE Solar Electric Vehicles! [PICS]


There are large steps and small steps that can be made to reduce our greenhouse gas emissions and other pollution. I think these solar electric vehicles are something in between, but definitely something to start using!

The Solar Electric Vehicle Company creates innovative electric shuttles (i.e. large golf carts) for universities, resorts, stadiums, governments, shopping malls, airports, arenas, medical centers, etc. that combine electric vehicle (EV) technology with solar power technology. Looks like a good combination.

Not only that, but these vehicles are FREE!

1st Solar-Powered Electric Vehicle (EV) Charging Station in NYC

Electric vehicles (EVs) are great, but better if you are not charging them from coal-powered electricity. Solar-powered charging stations are beginning to pop up now to address this situation. Dell headquarters in Texas planted some “solar trees” recently to charge their employees’ EVs, Chicago got its first solar-powered EV charging station in April, and now, New York just got its first one as well thanks to sustainable energy company Beautiful Earth Group.

There may be more on the horizon as well. EVs are looking to boom across the world.

1st World Ranking of Clean Energy Technology (CET) Sales — CET to Become 3rd Largest Global Sales Sector by 2020


The World Wildlife Fund (WWF) just released a comprehensive global report, and the first country by country ranking, of clean energy technology sales.

The clean energy sector is on the verge of becoming the third largest sector in the world now. The report — Clean Economy, Living Planet – Building Strong Clean Energy Technology Industries — finds that Denmark is currently the leading country in clean energy sales (relative to GDP), Brazil is second and Germany is third (the top three in absolute terms are Germany, the US and Japan).

With the sector booming, there is much opportunity for growth in these countries and others now. The report delves into how the countries currently leading the world got to the top and makes a short list of best practices.

Clean energy technology sales were about $921 billion in 2007 (€630 billion), but are expected to become about $2339 billion per year (€1600 billion) in 2020. At that volume, the sector is expected to only be behind automobiles and electronics in global sales. This is even without a strong, binding deal in Copenhagen.

Kim Carstensen, leader of WWF’s global climate initiative, says: “This is the clean economy growth happening now with only a partial Kyoto protocol international framework supporting clean energy development, patchy national support for green energy and huge subsidies to fossil fuel use.”

I think the growth in the future is liable to skyrocket with more and more countries getting serious about stopping human-induced catastrophic climate change. Plus, clean energy is an economic benefit for countries as it creates more jobs for the countries’ citizens.

Donald Pols, Head of the Climate Programme at WWF-Netherlands, says: “Clearly, from a national perspective there is much to gain and nothing to lose from investing in clean energy.”

Where do the US and the UK fit into this matter? And what are their and other countries’ best chances for becoming industry leaders?

Nanofarming Offers a Kinder, Gentler Way to Get Biofuel from Algae

One barrier to cost-competitive biofuel from algae is about to fall, and we may have nanofarming to thank for that.  The new technology uses tiny nanoparticles to absorb free fatty acids from living microalgae. It is being developed by the U.S. Department of Energy’s Ames National Laboratory and Iowa State University, in partnership with biofuel specialist Catilin, Inc.

In conventional biofuel production, algae are harvested and killed in order to extract their oil.  It’s not a very efficient process — sort of like uprooting a tree and stripping off the apples to make cider.  By coaxing out the oil on a molecular level, nanofarming enables algae to give up their product while continuing to grow.  Add Catilin’s non-toxic biofuel catalyst to the mix, and you have the makings of a more sustainable and cost-competitive biofuel – with some extra benefits, too.

Progress Energy Joins Stampede Away from Coal

Progress Energy is shutting down coal-fired power plants.

The trickle has turned into a torrent: following close on the news that a Michigan utility has converted a power plant from coal to sustainable biomass, Progress Energy Carolinas just announced that within the next seven years it plans to retire 11 coal-burning power units at four sites.

Progress Energy Carolinas is a subsidiary of Progress Energy, which is far from giving all of its fossil fuel operations the old heave-ho.  However, the move is still significant and Progress is no small potatoes.  It’s a Fortune 500 company with more than 3 million customers in three states, and the eleven units represent a huge chunk (about 1/3) of its coal-fired power generation fleet in North Carolina.  With friends like these, coal doesn’t need any enemies.
