Synthetic Biology For Natural Fuel

CoolBeans writes "Making ethanol is easy. Making enough ethanol to fill every gas tank in a developed country is tricky. The Department of Energy has promised $125 million to the Joint BioEnergy Institute, a team of six national labs and universities that will be run like a startup company. They intend to create new life forms that are optimized for alcohol production. The genes of crops that produce large amounts of cellulose will be tweaked to improve the yield per acre and to increase drought and pest resistance. Microbes that produce sugar from cellulose and ethanol from sugar will be built for speed and efficiency." The article mentions as an aside that earlier this year, "the energy giant BP gave $500 million to Berkeley, Lawrence Berkeley lab, and the University of Illinois at Urbana-Champaign for similar alternative energy research. That gift will fund the Energy Biosciences Institute, which will operate separately from the JBEI." So UC Berkeley and LBL are both participating in two separate energy-biotech research programs.

With modern particulate traps, new exhaust catalyst designs to reduce NOx output, and urea gas injection to reduce NOx output even further, today's diesel engines with their common-rail pressurized direct fuel injection are quiet, powerful and don't generate the bad exhaust of older diesel engines. Also, diesel fuel is full compatible with the current fuel distribution network for gasoline/diesel fuel, which is not true for delivery of E85 fuel and hydrogen for fuel cells.

    3) unlike algae it's grown by agricultiure so Archer Daniels Midland can get their cut of the pie.

    two reasons:
    1) Now matter how you produce it, evenif a miracle in effciency happened, at the end of the process any ethanol produced is going to be dissolved in water. Drying it out is going to eat the efficiency.

    2) Cellulose and Ligno-cellulose is desinged by trees to be indigestible and energetically inaccessible. If it were easy to digest the bacteria and termites would have eaten the whole forest a long time ago. Trees would not be huge cellulose containers. That should be a clue.

    Now it is true that man made enzymes can in some instances beat natural ones by an order of magnitude of more. But this is one place where nature has had a lot of different creatures all working on the same problem independently for quite some time.

    One the other hand it's almost commerically viable now. So we only need maybe a factor of ten improvement to open up wide spread production. However then other scaling issues will raise their heads. Farmland will be used. in many case it will be existing farm waste, but in others, say poplar trees, it will be for non-edible products. And if we try to open up new farmlands to compensate then were back to having a water budget problem.

    Algae making diesel would seem to bypass a lot of these problem. It can be grown off croplands, in many cases using sea water or brackish water. And it's easy to separate the oils from the water. the product has a higher energy value than Ethanol per volume and per weight. And it does not produce as much toxic waste in the production process (ethanol uses acid treatment and produces loads of crap to dispose of).

  18. Reference other than cypress hill ?? by sillyphisher1 · · Score: 2, Insightful

    The version I am familiar with is an acre of hemp producing as much as 4 acres of trees. My question is always: are we talking about the same acre of land? Or are we comparing Ohio farmland with Oregon forest land? What kind of trees? A lot of forest production in the western U.S. is on land too steep or rocky to be cultivated and planted with an annual crop. Even in your hybrid poplar production systems proposed for riparian areas, we are talking about land that we don't want to be tilling every year for the production of an annual crop. From a physiological basis, I doubt that a C3 plant like hemp could outyield a c4 plant like corn or switchgrass (panicum spp.) in a favorable environment

    It seems unlikely that biodiesel would all of a sudden start being produced in immense quantities while petrol suddenly disappears. Cheap, available biodiesel might help people buying a new cars consider diesel which is a step in the right direction.

    It is not as if ethanol is magically "compatible" with the majority of cars already on the road. My car won't take E10 let alone something with a significant ethanol component.

    There are no magic fixes. All solutions will take time to have an impact and no solution is an ultimate solution, rather we need to look to a variety of solutions together, put them out there and see what works.
