Biomass Based Fuel Supplements

 

The Department of Energy (DOE) has announced up to $15 million available to demonstrate biomass-based oil supplements that can be blended with petroleum, helping the United States to reduce foreign oil use, diversify the nation’s energy portfolio, and create jobs for American workers. 

Known as “bio-oils,” these precursors for fully renewable transportation fuels could be integrated into the oil refining processes that make conventional gasoline, diesel, and jet fuels without requiring modifications to existing fuel distribution networks or engines.

The Department expects to fully fund between five to ten projects in fiscal year 2012 to produce bio-oil prototypes that can be tested in oil refineries and used to develop comprehensive technical and economic analyses of how bio-oils could work. The proto-type bio-oils will be produced from a range of feedstocks that could include algae, corn and wheat stovers, dedicated energy crops or wood residues.

 Domestic industry, universities, and laboratories are all eligible to apply.

The results of the projects will inform future efforts directed at advancing bio-oil technologies and bringing these renewable fuels to market. A description of the funding opportunity, eligibility requirements, and application instructions can be found on the Funding Opportunity Exchange website under Reference Number DE-FOA-0000686.

The Energy Department’s Office of Energy Efficiency and Renewable Energy (EERE) accelerates development and facilitates deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality, and economic vitality.

 Sources of Alternative Energy

 

Alternative energy or renewable energy is important for creating clean energy future not only for the individual nations but the whole world. It offers excellent alternatives to the fossil fuels to reduce the emissions of carbon dioxide and greenhouse gases. The sources of the alternative energy are inexhaustible and one can rely on them for long-term basis Here are some important sources of alternative energy:

 

1) Solar energy:

The energy obtained from the radiations of the sun is called as solar energy. Sun is the massive source of energy releasing radiations since billions of years non-stop. The radiations emitted by sun are vital for all the plant, animal and human lives on the earth. At present solar energy is being tapped successfully for a number of applications.

Solar cooker is small box type equipment used for cooking of the food without requiring any additional fuel. There are number of variations of solar cooker with different efficiencies and different sizes. Solar water heaters are used extensively for heating water that can be used for bathing, domestic use and industrial purposes. It saves lots of electricity costs and the burning of other fuels like wood, coal, LPG etc. Another very important application of the solar energy is the photovoltaic or PV cells. The PV cells comprise of the solar panels that absorb solar energy and store them in the batteries. The energy from the batteries can be used for different domestic as well industrial applications

Besides these, there are number of other applications of solar energy like solar street lights, solar lanterns, calculators, mobiles etc. Solar energy is available abundantly in countries like India, China, US and others. It is considered to be one of the most resourceful sources of energy for future.

2) Wind energy:

The energy obtained from naturally flowing wind in the atmosphere is called as wind energy. Wind energy is available extensively in specific geographical locations without any costs. The wind in motion carries kinetic energy and it can be converted into mechanical and electrical energy. Presently wind energy is widely used for the generation of electricity.

To tap the energy from wind turbines are used. The wind turbine comprises of large blades looking like the fan. The blades are attached to the hub, which in turn is mounted on a shaft When the moving wind comes in contact with the blades it causes the rotation of the blades, which in turn causes the rotation of the shaft at low speeds. This shaft is connected to the gear box and causes slow rotation of the input gears and fast rotation of output gears and shaft. The output shaft rotates in an alternator that produces electricity. To get sufficient amount of grid power, large number of wind turbines are required at a specific location, which is called as wind farm or wind power plant.

3) Hydropower:

The power obtained from the flow of water is called as hydraulic power or hydro power or water power. The alternative energy from water can be obtained in a number of ways, the most popular being the hydroelectric power plants. In these power plants huge dams are built across the flow of the river. The water is stored in the dam at large heights and it carries potential energy. When the water flows down the potential energy is converted into kinetic energy. The flowing water comes in contacts with the large water turbines and makes them rotate in the transformer that produces electricity. Hydroelectric power plants are important source of electricity in a number of countries including US, China, India, Russia, and others.

Alternative energy obtained from the tides of the oceans is called as tidal energy. The waves in the waters of the oceans can also be utilized to produce electricity.

4) Geothermal Energy:

The heat energy obtained from the deep layers of earth is called as geothermal energy. The heat is produced continuously in the deep layers of earth, which can be utilized for various purposes like heating water, operating the heat pumps, producing electricity etc. Large amount of heat is generated in the core of earth and it gets conducted through the surrounding layers of rock. It comes to the surface of the earth in various forms like lava, hot springs etc, while other heat is stored below the surface of the earth. This heat is the geothermal energy and is available in unlimited quantity.

5) Biomass energy:

Biomass is the organic material obtained from the plants. The plants absorb energy from the sun by the process of photosynthesis so the energy is store in them. The biomass is the garbage leftover by the plants in the form of fallen leaves, broken branches, dead trees, wood chips, wasted crops etc. A number of other garbage and waste materials can be considered to be biomass. The energy obtained from the biomass is called as the biomass energy.

When the biomass is heated, the chemical energy within it is converted into heat energy, which can be used for heating water, producing steam, cooking food etc. Biomass can also be used to produce the methane gas, which can be used as the fuel. Rotten garbage and human waste can also be considered as biomass that can be used to produce methane, which is called as landfill gas or biogas. Biomass can also be converted biodiesel, which can be mixed with the traditional diesel fuel to run the vehicles.

Indirect land-use change (ILUC) means that if you take a field of grain and switch the crop to biofuel, somebody somewhere will go hungry unless those missing tonnes of grain are grown elsewhere.

Economics often dictates that the crops to make up the shortfall come from tropical zones, and so encourage farmers to carve out new land from forests.

Burning forests to clear that land can pump vast quantities of climate-warming emissions into the atmosphere, enough in

theory to cancel out any of the benefits that biofuels were meant to bring.
The European Commission has run 15 studies on different biofuel crops, which on average conclude that over the next decade Europes biofuels policies might have an indirect impact equal to 4.5 million hectares of land – an area the size of Denmark.
Some in the biofuels industry argue that the Commissions science is flawed and that the issue could be tackled by a major overhaul of agricultural strategy to improve productivity or by pressing abandoned farmland back into action. Waste products from biofuels production can also be fed to animals, they say, so reducing the pressure on land resources.

Conventional biofuels like biodiesel increase carbon dioxide emissions and are too expensive to consider as a long-term alternative fuel, a draft EU report says.

The study ‘EU Transport GHG [greenhouse gases]: Routes to 2050’ estimates that before indirect effects are counted, the abatement cost of reducing Europe’s emissions with biofuels is between €100-€300 per tonne of carbon.

At current market prices, this would make their CO2 reduction potential up to 49 times more expensive than buying carbon credits on the open market at €6.14 a tonne.   

But the EU’s authors conclude that it “it is not possible (and useful) to determine cost effectiveness figures for [conventional] biofuels” because their indirect effect - measured in cleared forests and grasslands (‘ILUC’) - make it a CO2-emitting technology.

The latest report will feed a growing unease about the reasons for the EUs original biofuels policy - justified in environmental terms - and the way it has developed since.

“The truth is that policy makers inside and outside Europe are doing biofuels for other reasons than environmental ones,” said David Laborde, a leading agricultural scientist and author of key biofuels reports for the European Commission.

“It’s a new and easy way to give subsidies to farmers, and it’s also linked to industrial lobbies that produce these biodiesels, and also what they will call energy security,” he told EurActiv.

“They want to diversify the energy supply, and keep their foreign currencies instead of buying oil from the Middle East. They prefer to keep it for something even if it is not efficient or even green,” he added.

The 10% target

In 2007, the EU first set a 10% target for the use of blended biofuels in transport by 2020.

Although the target was re-sourced from ‘biofuels’ to ‘renewable energy’ in 2009, analysts say that 8.8% of the EU target will still be provided by biofuels, and up to 92% of that will come from conventional biofuels like biodiesel.

Industrial associations disagree, putting the EU’s ratio of sugar-based ethanol, one of the best-performing biofuels, to biodiesel, one of the worst, at 22%-78%.

But both the original announcement and the Renewable Energy Directive two years later conditioned biofuel use on subsequently neglected criteria of cost-efficiency, sustainability and, where available, the use of second generation fuels.  

“I don’t think we are there on cost-effectiveness,” said Géraldine Kutas, Brussels representative of the Brazilian Sugarcane Industry Association (UNICA).

“There are no monetary provisions to support this in the directive, and second generation biofuels are still a promise. They are not commercially available yet,” she said.

Even trying to address the issue of indirect sustainability criteria for biofuels had gummed up the EUs policy-making process, she acknowledged. 

French farmers

Research by EurActiv has uncovered evidence that the EU’s original biofuels target was set as much for industrial and political reasons, as environmental concerns.

Claude Turmes, the European Parliament’s rapporteur responsible for steering the Renewable Energy Directive into law, said that business lobbies had influenced his negotiations with the then-French Presidency of the European Council.

“There were two lobbies, the sugar farmers lobby and the German car industry who tried to prevent the EU’s CO2 and cars legislation,” Turmes (Greens/Luxembourg) told EurActiv.

“The origin of the 10% renewables in transport target was the fact that these two lobbies joined forces to impose it on the Commission.”

EU insiders spoken to by EurActiv agreed, saying that biofuels had been a quid-pro-quo demanded for the imposition of ‘greener’ measures in the directive that would encourage wind and solar energy, and cut emissions. 

European sugar farmers had suffered in the 2006 Common Agricultural Policy reform which reduced the guaranteed sugar price by 36% and opened up the European sugar market to global competition.

A guaranteed market for agrifuel made from sugar-based ethanol held out some prospect of compensation. And the strength of the French farmers lobby made removing the 10% target “an absolute no go area” for Paris, Turmes said.

“The farm industry was obviously interested in biofuels, biochemicals and the bio-economy more generally,” Kutas added.

But Europe’s sugar farmers profited far less from the EU’s biofuels policy than growers of feedstocks for biodiesel, better suited to the continent’s diesel-based auto fleet.  

Car industry

EU officials say that the car industry was also instrumental in pushing for the biofuels target to be included as a compromise to bridge the gap between the 130g of CO2 per km that the EU wanted as a target for 2012 and the 140g that the car industry was prepared to offer.

“It was no secret,” a source told EurActiv. “It was very clear what they were lobbying for and it went all the way up the Commission”.

As a result, officials in the EU’s energy directorate responsible for biofuels did not treat research which questioned the fuel’s environmental credentials in the same light as that which supported it, multiple sources confirm.  

The EU’s biggest error was “that we started to make a policy without knowing the effect it would have,” Laborde said.

“We are now discussing the land use effect after saying for ten years that we need biofuels to reduce emissions,” he went on. “It was a serious mistake.”

Indirect emissions proposal

Brussels is due to publish a proposal measuring the indirect emissions caused by biofuels later this year, distinguishing between low-emitting biofuels such as ethanol and high-emitting ones like biodiesel.

But the EU’s decision-making process has been paralysed by the ongoing dispute between its energy directorate – which does not want ILUC factors considered – and its climate directorate, which does. And there are other problems too.    

Both the Renewable Energy and Fuel Quality directives contain ‘grandfathering’ clauses exempting all existing biofuels installations as of 2014 from further legislation until 2017.

As the biofuels industry’s existing capacity is already on the cusp of meeting the 10% target, according to a new report by the environmental consultants Ecofys, this would create massive overcapacity.  

The Institute for European Environmental Policy has calculated that on current trends, land conversion of between 4.7 million and 7.9 million hectares would be needed to accommodate the extra biofuels production, an area roughly the size of Ireland. 

But the introduction of any ILUC factor would probably rule out high-emitting conventional biodiesels, the majority of Europe’s biofuels production.

That would create a political backlash in EU states such as France and Germany, and potentially tear up the compromise which allowed the Renewable Energy Directive to be passed in the first place.  

For now, the proposal remains stuck in the corridors of an EU that appears equally frightened of the political consequences of admitting a policy mistake and the environmental consequences of denying it.
