Is plant oil needed to be made into biodiesel for use in engines to generate electricity in the Megawatt range?

Would appreciate knowing of engine manufacturers making engines to run on Biodiesel %26amp; /or Plant oilIs plant oil needed to be made into biodiesel for use in engines to generate electricity in the Megawatt range?
Vegetable oil oil is required for converting into bio diesel. This process of conversion is known as esterification in Chemistry. Any vegetable oil can do for this purpose. Even used oil can be converted. Any engine which runs on Diesel can run n bio diesel as well. I don't know if there is any manufacturer of engine who is producing engine which will run on bio diesel, since there is nothing special required in the enginer part to run on bio diesel. Hope this helps.Is plant oil needed to be made into biodiesel for use in engines to generate electricity in the Megawatt range?
Plant oils have different calorific values, so you have to be quite specific. Some plant oils must be processed to remove toxic substances contained in it, as well as to remove particles that might clog the injectors etc. Also there is considerable amount of impurities in plant oils that might affect performance.

Rubber seed oil is a good oil to be used in generating power in a general purpose diesel engine. (You should not use it in engines that have common rail system) But it has to be filtered properly and cannot be stored for long periods without deteriorating.

You first have to get a sample of the oil and test the calorific value, then you can calculate the amount of fuel needed to power the specific diesel generator you have. The manufacturer's manual for the engine will give you a rough indication of the amount of fuel you need. Remember you have to go through a few processes to convert the rubber seeds to obtain the oil.
The larger diesel engines such as those found in ships are designed to run on a wide variety of low grade oils as fuel. This is because there are no emission regulations in international waters, they want to be able to refuel at any port of call and they want to use the least expensive fuel possible. There's no need to transesterify vegetable oil into bio-diesel for these engines, they can burn the vegetable oil directly. The normal fuel for these engines is grade C bunker oil which is truly a horrendous quality of fuel, waste vegetable oil would be a treat to these engines. It's common for the used cooking oil to be simply tossed into the fuel bins on a ship.

These large engines are first started by a smaller engine as not only do they have to warm up but they are two stroke engines and require compressed air at the intake hence an auxiliary engine is needed to run the supercharger. Two stroke engines have double the number of power strokes in a cycle then four stroke engines.
you don't need an air compressor to run the diesel engine.

A 1 MW generator would consume about 2000 gallons/day of bio-diesel.
i really dont know abt rubber seed oil..but i used Pongamia oil on a small household genset and it burnt 1 liter in abt 2.5hrs on my small 2KVA unit

it was perfect and very encouraging..only problem is i find it difficult to source biofuel in my area on a regular basis

now coming to ur specific of the users has given a very very good reply..DIRECT veg oil and waste cooking oil can both be used in most non CRDI engines with varying efficiency..and without the need for ne major engine modifications.Pollution norms in cities are a different issue altogether though.

Biofuels derived from non edible plant oils like Pongamia and Jatropha need the process of transesterification to derive the usable biofuel from raw seed extract.
I don't know but maybe you can sell me some of that oil?

I'm in Massachusetts.

Email me on the price.
no only micro organisms.
I agree with other answers.
