The Pentagon the largest U S consumer of fuel goes green

,



Last month U.S. Army Energy Initiatives Task Force (AEITF) issued a draft request for proposals (Draft RFP) renewable energy contracts.

What’s on offer? Over the next decade, an impressive $7 billion. During the AEITF’s pre-solicitation phase, the Draft RFP is designed to gather information from potential bidders to assist the AEITF to develop a formal Request for Proposal (RFP) that it intends to issue later this year.

The United States Armed Forces, which currently fuels 77 percent of its machinery with petroleum-based fuel, has announced an aggressive goal, to be petroleum free by 2040. The Air Force intends to use biofuels for 50 percent of its domestic aviation needs by 2016.
A 2011 Pew Charitable Trusts report, “From Barracks to the Battlefield: Clean Energy Innovation and America’s Armed Forces” reported that Department of Defense clean energy investments increased 300 percent between 2006 and 2009 – from $400 million to $1.2 billion – and are projected at $10 billion annually by 2030, adding that that by 2015, the Pentagon will be spending $2.25 billion each year to harness clean energy technologies for air, land and sea vehicles.
Driving the Pentagon’s green drive is Executive Order 13423, which mandates that the Department of Defense achieve a 30 percent reduction in non-tactical fleet fossil fuel use by 2020.
A second key piece of legislation driving the Pentagon’s mandate is the Renewable Fuel Standard, which Congress enacted in 2005 as part of the Energy Policy Act, amending it in the 2007 Energy Independence and Security Act. The amended standard mandated that by 2022 the consumption volume of the renewable fuels should consist of: 15 billion gallons of conventional biofuels, mainly corn-grain ethanol; 1 billion gallons of biomass-based diesel fuel; 4 billion gallons of advanced renewable biofuels, other than ethanol derived from cornstarch, that achieve a life-cycle greenhouse gas threshold of at least 50 percent; and 16 billion gallons of cellulosic biofuels produced from wood, grasses, or non-edible plant parts, such as corn stalks and wheat straw.
The draft AEITF RFP marks the beginning of the AEITF’s plan to develop a large, coordinated procurement process for renewables. The AEITF’s new program was developed in response to a National Defense Authorization Act that requires Department of Defense facilities to derive at least 25 percent of the electricity they consume from renewable energy by 2025, and a Department of Defense “Net Zero Energy” initiative, which challenges DOD installations to produce more energy than they consume, with emphasis on the use of renewable energy and alternative fuels.
So, what is holding back the production of commercially viable amounts of biofuels? Key barriers to achieving the renewable fuel mandate are the high cost of producing biofuels compared with petroleum-based fuels uncertainties in future biofuel markets, a lack of subsidies and crop insurance, along with a shortage of significant investment.
These factors have combined to produce a “perfect storm” up to now for biofuel producers, resulting in “designer fuels” of high cost for Pentagon testing.
To give but one example.
In October 2010 the Navy purchased 20,055 gallons of algae biofuel at an eye-watering cost of $424/gallon.  Nevertheless, the contract was one of the biggest U.S. purchases of a non-corn ethanol biofuel up to that time. A year later, the Navy reportedly spent $12 million for 450,000 gallons of biofuel. The bad news was that the biofuel’s cost worked out to around $26.67 per gallon, roughly six times the current cost of traditional gas.
The good news?  In a single year, the cost per gallon of biofuel plummeted by a factor of 15.9.
Furthermore, $7 billion in funding is likely to prove a significant game changer in the field.
So, where does this leave the investor? No single biofuel source, from jatropha, algae or camelina has yet to emerge as the clear winner, though the last seems most likely to emerge as the frontrunner. Accordingly, investors must do their homework and seek out potential winners.
For those wishing to broaden their portfolios, two websites will prove of immense value.
The first is www.usa.gov, the federal government’s website for the U.S. government, where one can come to grips with federal legislation and Pentagon initiatives.
The second is Jim Lane’s http://www.biofuelsdigest.com/, the self-proclaimed “world’s most widely read biofuels daily.” While the site has an element of tub-thumping boosterism, it nevertheless remains an immensely valuable source of information about the biofuel market and the major players.
It is important to remember how different the biofuels picture is now from even a year ago. The Pentagon, the largest U.S. consumer of fuel, is now under pressure to meet the various federal mandates, and careers and promotions hang in the balance.

 ALGAE AND BIOFUEL
 

Algae: An Important Source for Making Biofuels

Biofuels are the alternative fuels like ethanol, butanol, biodiesel, methane and others obtained from the biomass. Biomasses are the wasted materials obtained from the plants, animals and human beings. With the increasing prices of the crude oil and importance of achieving self-reliance in energy and growing concern for the environment alternative fuels are receiving more government and public attention.

The government of US has set the targets for using of 36 billion gallons of biofuels by the year 2022 as a result most of the gasoline sold here is mixed with ethanol. Similarly, biodiesel mixed with petroleum diesel is found to create lesser pollution without affecting the performance of the engines. Methane gas is also increasingly used for the production of electricity and also driving the vehicles. Ethanol, biodiesel, and methane are all biofuels obtained from biomass like wasted crops, crops containing sugar, vegetable oil etc.

Due to increasing demands of the biofuels, many farmers are now tempted to raise the crops that would yield biofuels instead of the food crops. This leads to misuse of limited resources available in the form energy, fertilizers and pesticides. In some parts of the world large areas of forests have been cut down to grow sugarcane for ethanol and soybeans and palm-oil tress for making biodiesel. US government is making efforts to make sure the farming for biomass materials does not competes with the farming of food crops and that the farming of biomass would require lesser fertilizers and pesticides.

Algae used as Biomass

One of the most important promising sources of biofuels is algae. Algae are single celled (most of them) microorganisms that grow in salt water, fresh water and even in contaminated water. Algae can grow in sea, rivers, ponds, and also on land not suitable for production. Like other plants, algae also absorb energy from the sun in the presence of atmospheric carbon dioxide by the process called photosynthesis. Just like other wasted plants and crops, algae also carry energy and it can be used as an important biomass material. There are more than 65,000 known species of algae having different colors like green, red, brown and blue-green that offer wide range of options for obtaining the biofuels from them.

Algae keep growing extensively in the nature and it generates lots of waste that could even create problems of disposal. Since algae carries energy, it can be used as an important source of alternative or renewable energy since algae is available in abundant quantities that can last forever. Algae can be used as the biomass materials to obtain various biofuels. Various colonies of algae can be considered to be small biological factories containing lots of energy.

Biofuels from Obtained from Algae

Like the wastes from the plants, the algae can also be used as the biomass to produce various types of biofuels. One of the most popular types of biofuels, biodiesel, is obtained from the vegetable oil. The same biodiesel can also be obtained from algae oil. The biodiesel from algae can be mixed with the petroleum diesel and used for the running of the vehicles. It can also be used as the fuel for jets, airplanes, refineries, and pipelines. The biodiesel obtained from algae can be readily used with automobile and jet engines without the need to make any modifications in the engine. It meets all the specifications of the petroleum diesel fuel.

The algae biomass can also be used for making ethanol and butanol biofuels, which are type of alcohols. Butanol is considered to have more efficiency than ethanol and it is obtained from dried algae that act as a biomass. The carbohydrates extracted from algae are converted into natural sugars, which are then converted into butyric, lactic and acetic acids by the process of fermentation. Further fermentation of butyric acid is carried out to produce butanol.

The biomass obtained from algae can also be used to produce biogas that contains methane and carbon dioxide. Methane is an important component of natural gas, so this biogas can be used just like the natural gas for producing heating effect and also to produce electricity.

Advantages of using Algae as Biomass

One of the important advantages of algae it that it can be grown in almost any type of water: salt, fresh, and even contaminated water. It can be grown in vast sea and river water, small rain water ponds and even commercial or domestic manmade ponds. It can also be grown on non-arable unproductive lands increasing the utility of waste lands.

Another important advantage of growing algae for producing biofuels is that it does not displace the farmland used for growing the food crops. The farmers using various resources for producing biodiesel instead of the food crops has been one of the major concerns for the government, algae helps solving this tricky problem.

Algae have the potential to yield 30 times more energy than the crops grown on land, which are currently being used to produce the biofuels. This would further encourage the use of algae for producing biofuels and land for producing food crops.

Another important advantage of algae is that it uses carbon dioxide for its growth. Thus the pollution causing carbon dioxide produced from the other sources can be utilized to grow algae, which helps keeping the environment cleaner.
