DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

These methodologies will significantly decrease the levelized cost of energy (LCOE) of the final HKT design. The innovative new turbine designs, along with distributed load control and regulator concepts, significantly reduce the levelized cost of energy. It has a low maintenance cost, resulting in a lower cost of energy.

USC study shows promising potential for giant-kelp-based biofuel with depth-cycling approach

Green Car Congress

physically moving the macroalgae between deep nutrient-rich water at night and shallow depths within the photic zone during the day to optimize growth. 13 C values suggesting that the depth-cycled kelp were not nitrogen-deficient and assimilated nutrients from deep water. The researchers used a depth-cycling approach—i.e.,

DOE reports show major potential for wave and tidal energy production near US coasts

Green Car Congress

These new wave and tidal resource assessments, combined with ongoing analyses of the technologies and other resource assessments, show that water power, including conventional hydropower and wave, tidal, and other water power resources, can potentially provide 15% of our nation’s electricity by 2030.
