In summary, Sir Richard Branson put on another display that highlighted some technical and business advances on the use of biofuel instead of the traditional kerosene source for jet fuel. The demonstration involved flying a 747 Sunday from London to Amsterdam using one of the four engines using a bio/traditional mix. Meanwhile, Branson drank of a shot of his new fuel.

Showman Sir R. Branson put on another display that highlighted some technical and business advances on the use of biofuel instead of the traditional kerosene source for jet fuel. Branson's Virgin Airways flew a 747 Sunday from London to Amsterdam w/ one of the four engines using a bio/traditional mix. Meanwhile Branson drank of shot of his new fuel.

Notables:
  1. Production of a biofuel that won't freeze at jet altitude: -47C
  2. Cold temp bio jet fuel made by: http://www.imperiumrenewables.com/"
    - Seattle based
    - Founded 4yrs ago by John Plaza
    - Planter likes algae for his future bio crop; likes sewage processing tanks as a major algae source
  3. Branson pitching tax breaks to EU governments for using bio jet fuel

Baby steps, though. Branson's got his heart in the right place, but he readily acknowledged that this was a feasibility demonstration. We've got a long way to go before we can make this type of fuel plentiful, sustainable, and environmentally-friendly. I have high hopes for the algae-oil guys like Ivan and hope that they can feed those little rascals with processed sewage so as to reduce the energy-costs of sewage treatment and get some energy back out. One thing to watch is methane production. It is a potent greenhouse gas, and it can form in copious quantities in anaerobic digestion processes.

Sure its a start. I should have emphasized the breakthrough more: cold weather biofuel. People were saying this would never be done at aviation temperatures.

You're right about that. We don't have the details, though. Most biofuels in transportation applications have to be pre-heated to keep them from gelling at low temperatures, even in mundane uses like supplementing diesel fuel in cars and trucks. Normally, you'll have to run a vehicle on diesel for a period, and use the waste heat from that engine to pre-heat and liquefy the biofuel before you can start bleeding the biofuel into the fuel stream. This is a problem that students at Unity College here in Maine have been tackling. We have cold winters, extremely high fuel prices, and long commutes between where you might live and where there might be a job that pays enough to support your family.

The only comment in the WSJ piece is "Imperium came up with a process that yields fuel that won't freeze at minus-47". The IR website has absolutely no further relevant tech. details. I think its safe to assume no mechanical alterations would be allowed to the fuel system of the aircraft (like additional fuel heating) so the cold weather enabler in this case has to be all in the in fuel composition.

There was a thing about this kind of technology on the Science channel. Basically, the airlines and Boeing have said "We won't change our engines to run your fuel, you must change your fuel to run on our engines." They did something with pressure and, I think, an autoclave process to convery WVO more or less, into a fuel that was very close and fully interchangeable with kerosene.
 

1. What is biofuel and how does it differ from traditional jet fuel?

Biofuel is a fuel derived from renewable biological resources such as plants, algae, and waste materials. It differs from traditional jet fuel, which is typically derived from fossil fuels, in its source of production and its potential to reduce greenhouse gas emissions.

2. Why is biofuel being considered as an alternative for jet fuel?

Biofuel is being considered as an alternative for jet fuel because it has the potential to reduce the environmental impact of air travel. It produces fewer greenhouse gas emissions and can help airlines meet their sustainability goals. Additionally, as traditional jet fuel prices continue to fluctuate, biofuel offers a more stable and potentially cost-effective option.

3. What steps are being taken to incorporate biofuel into the jet fuel market?

Several steps are being taken to incorporate biofuel into the jet fuel market. This includes research and development to improve the production and efficiency of biofuels, partnerships between airlines and biofuel producers, and government initiatives and incentives to encourage the use of biofuels in aviation.

4. How does the use of biofuel in jet engines affect their performance?

The use of biofuel in jet engines has been shown to have similar or even improved performance compared to traditional jet fuel. Biofuels have a higher energy density, which can result in increased engine power and efficiency. They also have a lower freezing point, making them more suitable for use in colder climates.

5. What are the potential benefits and challenges of incorporating biofuel into the jet fuel market?

The potential benefits of incorporating biofuel into the jet fuel market include reduced greenhouse gas emissions, improved energy security, and potential cost savings. However, there are also challenges such as the limited availability and scalability of biofuel production, potential impacts on food production, and the need for further technological advancements to make biofuel a viable alternative for large-scale commercial aviation.
