Back then, we failed to realize the implications of our actions or the repercussions of a developed society highly dependent on petroleum and incessantly slave to the dictates of the mighty oil barons.

When automated vehicles were first introduced to the world, could anyone have anticipated the vast impact it will have to the economy? Who would have thought that combustion engines would turn out and be the backbone of today’s society? Decades ago, this idea seemed to be too great to fathom. However, its environmental impact was then, not recognized probably because of lack of foresight.



Biodiesel: Pros

•    Right here and now, what we have is biodiesel. This is an alternative for petroleum-based fuel that boasts a cleaner burn as compared to its expensive and environmentally unsound counterparts.

•    Biodiesel is a  renewable fuel source that stems from various resources including vegetable, canola, palm, and soybean oils.

•    In addition, this fuel releases far less nitrogen oxide, carbon monoxide, and unburned hydrocarbons. And since biodiesel processors convert vegetable oil, it is biodegradable and non-toxic. Do not forget the absence of sulfur products as oppose to petro-diesel. Given this lack of sulfur, biodiesel still possesses the required viscosity to fully lubricate diesel engines, which cannot be easily arrived at when dealing with low-sulfur petroleum products.

•    With the proper biodiesel equipment, the fuel output can be used in almost all diesel engines with modifications that are considered discretionary. Also, having a renewable fuel source will moderate our reliance on foreign oil corporations, or dare we say, the Middle East oil tycoons. If local farmers produce the needed raw material for our biodeisel, then we do not need to import oil because we can manufacture it ourselves, right?



Biodiesel: Cons

•    The fuel generated by biodiesel processors is an inherent solvent; meaning, sooner or later it will trigger the deterioration of various rubber components such as hoses and pumps. Though this can be easily replaced by visiting your local dealer. Sometimes extra tubing is included in a biodiesel expansion pack. This package is ideal if you plan to make batches and batches of biodiesel.

•    Also, this solvent characteristic will clean the injectors and the tank, as well as the fuel lines; the downside is that, blockage is inevitable. But this is not a reason to be worried. Just prepare yourself to a frequent filter change for the first couple tanks of biodiesel.

•    As for the gel point, biodiesel posts higher than that of its petroleum equivalent. This connotes that the former coagulates faster. But, this too, can be resolved by using an anti-gel additive.

•    The last issue lies on the recent introduction of biodiesel. This is fairly new and consumers may have a hard time locating biodiesel processors and kits. Well, a quick search in the World Wide Web is the solution for this one.

Whether you prefer it straight up or mixed (20% biodiesel to 80% petroleum diesel), so long as nature is unscathed, then it is all good. This alternative could be one of man’s greatest achievements. Though this time around, we need to take the time to become aware of its pluses and minuses, including the ideal method of generating, regulating, and utilizing this precious liquid we call biodiesel.

Matt Oconnor asked:


The processing of biodiesel may require a number of biodiesel filters in order to ensure that the end product is of excellent quality. When you try to recycle waste vegetable or surplus corn oil and make them into biodiesel, you might need a biodiesel filter for your engine to make sure that contaminants can’t enter into the engine and damage it. Different biodiesel filters may be required for a number of different applications.

Biodiesel filters should have the following properties in order to work best in any given conditions:

1. High Temperature Properties. Almost any filter media can be used for water-based products. But in the case of filtering hot oils, resins and other high temperature products, a filter media that can withstand prolonged exposure to high temperatures is preferred. Biodiesel filters should be able to have excellent high temperature properties to be able to handle the filtration of biodiesel well enough.

2. Excellent Filtering. Biodiesel filters should be able to filter out the contaminants well enough in order to make a better grade product. All filters have a micron rating that determines the size of the particles that can be effectively captured by the filter media. A biodiesel filter having a 5 micron rating is preferred to provide excellent filtering properties.

3. Chemical Compatibility. A biodiesel filter should be able to withstand exposure to such chemicals as solvents, acids and alkaline solutions. A lesser quality filter may break down when exposed to such chemicals. Make sure that the biodiesel filter that you use has the property to withstand breaking down when exposed to such chemicals.

Biodiesel has become a very popular fuel alternative to petroleum-based fuel today. That is why more and more people are trying to make use of biodiesel in order to lessen their reliance on fuels based on fossil oil, which can pollute the environment. With biodiesel, people have the option to make use of a cleaner alternative. Here are just some of the key advantages of using biodiesel:

1. The use of biodiesel produces at least an 80 percent reduction in carbon dioxide emissions. Not only that, biodiesel contains little or even no sulfur content that can result in as much as a hundred percent less sulfur dioxide being released in the air.

2. Biodiesel is the only alternative fuel available that can run in any conventional diesel engine. Other alternative fuels such as waste or straight vegetable oil may require your diesel engines to be modified. This is not so with biodiesel. Anyone can use biodiesel immediately to fuel any conventional diesel engine today.

3. Biodiesel contain less unwanted contaminants that can do some damage to diesel engines. Biodiesel also has better lubricating properties than petroleum-based diesel and can help protect and extend the life of diesel engines. It’s a better solvent than petro-diesel and may therefore help clean the fuel lines and the engine itself by dissolving fuel residues and flush them out.

4. Biodiesel in non-toxic. It is safer to handle and transport. It is also highly biodegradable and has a higher flashpoint than conventional diesel.

5. Biodiesel can be produced from renewable oilseed crops such as soybeans, canola and mustard seed. As a renewable resource, production of this alternative fuel can go on and on as long as cultivation of such crops is continued. There is also research being done in trying to raise and harvest oil-rich algae as another source for the production of biodiesel.

Algae is a major renewable fuel which can be used to manufacture Biodiesel. One of the companies in New Zealand successfully developed a system for using sewage waste as a substrate for algae and then it produce bio-diesel. An alga is considered as the highest yield feedstock for biodiesel that can produce more enough oil compared to soybeans when grew in an acre.

Actual Biomass algae produced from field trials, which is conducted during the NREL’s aquatic species program. It is being converted using the actual oil content of the algae species grown in the specific program.

There are various advantages of producing biodiesel from algae, which include rapid growth of the plant. Using Algae Biodiesel gives high per acre yield. Algae biodiesel does not used to contain sulfur, toxic materials and it is highly biodegradable. There are some species, which are ideally suited for algae biodiesel production, because their high oil contents in some species.

Algae used to develop from small, singled celled organisms to cellular organisms, some algae have complex distinguished form. Algae can be easily seen at places like damp, bodies of water. Algae are common in terrestrial as well as aquatic environments. Like any other plants algae require three elements to spring up sunlight, carbon-di-oxide and water. Plant algae and some other bacteria convert sunlight to chemical energy, which process call as photosynthesis. Algae used to contain 2% and 40% of lipids or oils by weight. If algae have greater oil, it may results in lower yield annual food crops such as soybeans. Currently only 0.3% of the land of the US, it is getting utilized to produce enough biodiesel.

Species of algae with up to 50% oil content have conclude that only 28000km land getting used to produce biodiesel. Unused desert land could be used for effective growing of algae.

GreenFuel Technology, where emissions to Biofuels process, photosynthesis which grows algae, it capture CO2 and it produce high energy biomass. The algae can be economically converted to solid fuel, methane or liquid transportation fuels like biodiesel and ethanol.

Keith McGregor asked:


As November 1st 2008 approaches and the end to UK Red Diesel derogation, yacht owners are sharing an interest in alternative fuels one being Biodiesel. What are the benefits for boat owners and who will supply it?

Biodiesel refers to a non-petroleum-based diesel fuel made vegetable oils or animal fats.

There are many advantages of marine biodiesel as a marine fuel



Biodiesel serves as a drop-in replacement for petro diesel — no conversion necessary.

Biodiesel when used in boats causes less water pollution – there is less smoke and it is safer to store.

Biodiesel production uses a third less energy than petroleum diesel production.

High lubricity extends engine life

Higher cetane rating (46-62) almost always smoothes engine operation

Biodiesel can be blended with petroleum-based diesel at any ratio

Biodiesel contains essentially no sulfur or aromatics. Blends as low as B20 have reduced soot exhaust by 83%. Biodiesel removes deposits in tanks and fuel systems left by petro diesel.

Cheaper than the current red diesel prices of 88pence per litre even before the additional 54.94p in duty to be added from 1st Nov 2008.



Disadvantages



Doesn’t store as well as petro diesel

Possibility of blocked filters as it cleans the lines out and failed rubber seals as Biodiesel is a better solvent than mineral diesel

Blends of more than 5% (B5) to 95% (B95) may invalidate engine warranties

No Bio Diesel suppliers and blending facilities in marinas or boatyards at present.



Conclusion

Whilst at present there are no direct suppliers of marine biodiesel for boat owners, there are plans for the 2009 Portland Marina in Dorset to supply biodiesel and several marinas advise they have spare tank capacity to store another grade of oil.

A recent farm-based bio-diesel plant in North Wales has been reported as receiving interest from yacht and boat owners already. BML Biofuels, based at Llanfihangel GM, near Corwen is the first plant in Wales - and only the second in Britain - to extract oil by cold pressing oilseed rape (OSR). At the resulting cost 45p-55p/litre for the first 2,500 litres plus tax, it’s then no surprise BML Biofuels has already received maritime inquiries as far afield as Portsmouth since its official June opening.

With the higher cost or red diesel and a government under pressure to meet renewable fuel targets Biodiesel is likely to become a key ingredient in the refueling of motor yachts over the next decade.
