Even better, algae could efficiently absorb the carbon being put out by fossil fuel power plants, producing a biofuel that is close to being carbon neutral.

更好的是，藻类可以有效地吸收化石燃料发电厂排放出来的碳，制造出近乎碳中和的生物燃料。

Trent acknowledges that challenges remain in figuring out the right algae strains, and in engineering the system to make algae biofuels a cost-effective alternative to existing fossil fuels.

特伦特承认，在塑料袋中计算出藻类合适的株数，以及在工程系统中使藻类作为一种可替代现有化石燃料的低成本燃料，具有一定的挑战性。

Algae has become one of the hotter commodities in the quest for fossil fuel alternatives, said Michael Frohlich, a spokesman for the National Biodiesel Board, a Missouri-based trade organization.

位于密苏里州的行业协会——国家生物柴油委员会的发言人Michael Frohlich曾说到，在寻求化石能源替代物的道路上，海藻正成为越来越热门的候选品之一。

But he is hard at work. He and his team currently are trying to make algae that can change carbon dioxide back into fossil fuel.

According to a life-cycle analysis, the land-based crops all were found to sequester more carbon than that incurred in growing them, while the contrary was true for growing algae, meaning that replacing fossil fuels by algal fuels could cause an overall increase in carbon emissions.

Algae can be fed from waste-streams of CO2 from fossil-fuel power stations as a carbon elimination strategy and can also decontaminate groundwater, so there is a potential mix of environmental solutions in aid of a common goal of fuel beyond oil.
