Georgia Tech prototype triboelectric nanogenerator could extract energy from ocean waves

Green Car Congress

Researchers at Georgia Tech have developed an inexpensive and simple prototype of a triboelectric nanogenerator that could be used to produce energy from ocean waves by making use of contact electrification between a patterned plastic nanoarray and water. A report on their work is published in the journal Angewandte Chemie. —Lin et al.

Ryder’s natural gas fleet surpasses 20 million miles

Green Car Congress

a leader in commercial transportation and supply chain management solutions, reports that its fleet of over 500 natural gas vehicles has surpassed 20 million miles (32 million km). In 2013, Ryder opened the first natural gas fueling stations in its North American network to serve both the general public and Ryder lease and rental customers.

NREL/UGA study finds microbial enzyme digests cellulose ~2x fast as current leading commercial cellulase; implications for biofuels cost

Green Car Congress

NREL researchers put CelA to the test and found that it produced more sugars than the most abundant cellulase in the leading commercial mixtures, Cel7A, when acting on Avicel, which is an industry standard to test cellulose degradation. This discovery could reshape the landscape of commercial cellulase cocktail design.

Westwater Resources is building a facility in Alabama to process one of the largest graphite deposits in the US

Charged EVs

We first met Jon Jacobs back in 2013, when he was working at Wildcat Discovery Technologies, a battery research firm that developed an innovative process to rapidly synthesize and evaluate energy storage materials. Just one of SK’s plants in Kentucky or Georgia or Tennessee would require roughly that amount of graphite.

NREL enzyme enables conversion of biomass to sugar up to 14x faster than current alternatives; changing the economics of conversion

Green Car Congress

In one scenario, the best commercially used enzyme converted sugars at a 30% extent in seven days. CelA converted to double that extent. Conventional cellulases such as Cel7A (left side of figure) use a surface ablation strategy to deconstruct cellulose, converting single layers of cellulose strands. —Berlin (2013).
