Sweden Now Using More Biofuel Than Oil


There's more news on the sustainable and renewable energy front in Europe. Not only is wind power nearly on natural viagra alteratives par with natural gas in Europe, but in Sweden now, biomass has passed oil as the top source for energy generation. The most recent figures indicate that biomass energy production reached 115 terrawatt hours in 2009, representing 32% of all energy consumption. At the same time, oil-based fuels were used to produce 112 TWh.  Biofuel use is expected to increase, while fossil fuel use should further decline in the coming years.

Biofueled combined heat and power (CHP) plants generate heat for more than half of the multifamily dwelling units in Sweden, as well as producing electricity. Sweden has a goal to have renewable energy reach 50% of all energy consumed in the country by 2020 and to be independent from imported fossil fuel for all transportation by 2030.

Wood is the source for the vast majority of the fuel used. However, the increased use of wood for energy has led to higher prices for other products requiring logs and paper pulp.

Green Hornet Will Go Supersonic on Biofuel

As you may recall, last August the cialis en gel Navy put out a call to biofuel companies for 40,000 gallons of only today cheap levitra soft fuel to start testing in their F/A-18 Super Hornet jet.  Sustainable Oils ultimately won the contract to develop biofuel for the military branch and now the Navy is prepared to take the Hornet on a supersonic flight using a blend of 50 percent jet fuel and 50 percent camelina-based oil.

Tomorrow, at the Air Station at Patuxent River, Maryland, the so-called "Green Hornet" will fly over the Chesapeake Bay, hopefully proving that biofuels can perform well in a full range of flight operations, including traveling faster than the speed of sound.  The Super Hornet was picked as a test craft for biofuels because it's the Navy's largest aviation fuel-consumer.

Camelina biofuel has shown itself to be a great choice for jet fuel blends because it can work as a drop-in replacement for jet fuel.  All aircraft systems -- fuel gauge, etc. -- operate the buy generic viagra cialis same as if it were straight petroleum.  Also, a recent study found that the use of camelina jet fuel could reduce carbon emissions by 84 percent compared to order viagra usa regular jet fuel.

The Hornet won't be the only naval craft to get a makeover though.  The Navy has committed to getting half of their energy from renewable sources by 2020, which will include cleaning up ships, aircraft and all of their power systems.  The U.S. military is the world's greatest consumer of petroleum, so their commitment to reducing that consumption is an important one.

British Airways Turning Waste into Jet Fuel

British Airways has announced that it will start producing jet fuel from landfill waste to reach its target of 50 percent reduced emissions by 2050.

The airline is partnering with biofuels company Solena to construct a waste-to-energy fuel plant in East London that will turn 500,000 tonnes of organic waste into 16 million gallons of jet fuel per year.  The fuel will be made by treating the the waste in a high-temperature gasifier to create BioSynGas which is then converted to tramadol next day delivery no prescription jet fuel using the Fischer Tropsch process.  The plant will also create a by-product of 20 MW of electricity per year and have the added benefit of keeping waste out of landfills.

British Airways is buy levitra online australia only committing to use a 10 percent blend of the biofuel at this point, a disappointment when you consider the successful test runs of 50/50 bio-jet fuel blends.  The airline plans to start using the fuel by 2014.

Study Says Algae Biofuel Has Dirty Life Cycle

Algae has seemed like a great biofuel candidate because it's extremely efficent at creating energy from sunlight and it could potentially form closed loops for power plants - absorbing exhaust while creating new fuel - but a recent study has knocked algae off its pedestal.

University of Virginia researchers have found that the life cycle of algal biofuel produces high levels of levitra pharmacy in india greenhouse gas emissions -- much more than it sequesters.

The culprit is the large amount of fertilizer used to produce the purchase propecia algae.  The fertilizers come from petroleum-bases sources and emit nitrous oxide.  The researchers propose using fertilizer from sewage plants as a way around the problem.

It looks like we're still far away from an ideal biofuel, if there is one.

KLM Testing Biofuels on Passenger Flight

As many of us in the U.S. are planning our Thanksgiving menus, Dutch airline company KLM is planning the first biofuel flight with passengers on board.  On November 23, a Boeing 747 will take off running on a 50/50 combination of biofuel and jet fuel.

The biofuel being used in this test flight will be made from camelina, a feedstock that produces 84 percent less emissions than regular jet fuel and has proven to be a low-impact crop, requiring less water and fertilizer and can grow in areas where food crops won't be displaced.

Other test flights have been done using other feedstocks like jatropha and without passengers with positive results, but this will be the first using a purely camelina biofuel and with people (other than the pilot) onboard.
