International Energy, Inc. has announced the development of new nutrient delivery protocols for more efficient and enhanced growth of hydrocarbon accumulating microalgae.
Nitrogen and phosphate nutrients are among the biggest costs in cultivating algae for biofuels. Sandia molecular biologists Todd Lane and Ryan Davis have shown they can recycle about two-thirds of those critical nutrients, and aim to raise the recycling rate to close to 100 percent. Recycling nitrogen and phosphate has benefits that go far beyond cost. While nitrogen can be produced through a costly artificial nitrogen fixation process using natural gas and atmospheric nitrogen, phosphate is a limited natural resource that can be toxic at high concentration.
This spring farmers responded to the ethanol industry's demand for grain by increasing their corn acreage by 19 percent over last year, according to U.S. Department of Agriculture estimates. What if that happens again next year?
Unlike today’s energy crops, such as corn and soybeans, growing kelp doesn’t require land, fresh water or fertilizer. And giant kelp can grow over a foot per day under ideal conditions.
How can we radically collaborate to make the right choices – and the right investment decisions – to mobilize global markets and accelerate the establishment of a sustainable, low-carbon economy?
A nascent biochar industry is emerging in connection with biomass power technologies that coproduce electricity and char via gasification and pyrolysis.
A unique bioreactor at the Energy Department's National Renewable Energy Laboratory (NREL) can help find the ideal locations for farms to produce algae that could someday compete with renewable diesel, cellulosic ethanol, and other petroleum alternatives as transportation fuel.
Farmers in the UK are still discussing the merits of anaerobic digestion, but in Italy things are moving on along. When the European Union first set out its environmental sustainability parameters, the Italian government responded with an incentive scheme to encourage small farms to generate electricity from biomass energy crops using anaerobic digestion. One of those farms was the Azienda […]
Intensive animal farming produces large amounts of waste – about 75 kg per cow, per day – that is both a source of methane pollution and a potential groundwater pollutant. Using anaerobic digestion to treat animal slurry can provide a solution to this problem, as well as renewable energy. Germany has 2500 farms producing power from on-farm plants, so what would it take for the US to follow suit? Brent A. Gloy looks at the technology, the issues, and the way forward.
OriginOil Inc. announced the recent filing of its Patent Cooperation Treaty, or PCT application, entitled "Apparatus and methods for photosynthetic growth of microorganisms in a photobioreactor." This filing consolidates previous OriginOil inventions and adds new developments since the original filings.
