Not exactyly sure the point so don't want to infer, but would say that such could be done without a carbon tax or regulation. Just need the cost of the algae fuel to be competitive in the market.
And a lot of space...
I'm all for alternative energy, algae based fuel, firiing boimass, solar, etc. I just believe it should be market based and winners and losers shouldn't be picked by beauracrats dabbling in social engineering with other people's money.
Green Star, for instance has created a micronutrient that makes algae increase its lipid production by 34%. Their technique combined with the use of municipal waste water will provide ideal conditions for algae growth.
Joule Biotechnologies has a process that it says can make 20,000 gallons of biofuel per acre per year. Their process will be competitive with crude oil at $50 a barrel. ExxonMobil is predicting 100,000 gallons of bio-fuel per acre per year. They are working on genetic engineering methods to create super algae that not only will produce oil, but also methane, natural gas and hydrogen gas.
The big thing is the use of CO2 from coal fired plants. “The reason algae is so interesting is that it can directly convert CO2 into biomass very quickly, more efficiently than anything else we know of,” says Rodney Andrews, director of UK’s Center for Applied Energy Research. This effort will make available an alternative fuel that may become cheaper than petroleum based fuels. And it will use CO2 as a biomass food. CO2 is really our friend.
