International Energy Develops Protocols for Algal Growth

International Energy Develops Protocols for Algal Growth

International Energy, Inc. has announced the development of new nutrient delivery protocols for more efficient and enhanced growth of hydrocarbon accumulating microalgae.
Algae Nutrient Recycling is a Triple Win

Algae Nutrient Recycling is a Triple Win

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.
The Sustainability of a Bioeconomy

The Sustainability of a Bioeconomy

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?
Move over, corn and soybeans: The next biofuel source could be giant sea kelp

Move over, corn and soybeans: The next biofuel source could be giant sea kelp

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.
Decarbonization requires radical collaboration

Decarbonization requires radical collaboration

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?
Could Biomass Technology Help Commercialize Biochar?

Could Biomass Technology Help Commercialize Biochar?

A nascent biochar industry is emerging in connection with biomass power technologies that coproduce electricity and char via gasification and pyrolysis.
Unique Bioreactor Finds Algae’s Sweet Spot

Unique Bioreactor Finds Algae’s Sweet Spot

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.
Generating Biogas from Biomass

Generating Biogas from Biomass

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 […]
Biogas: what options for Slurry power in the US?

Biogas: what options for Slurry power in the US?

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.
