How Governmental Greenhouse Gas Science Has Been Weathered Through Time And Why It Matters, Christopher Apple
How Governmental Greenhouse Gas Science Has Been Weathered Through Time And Why It Matters, Christopher Apple
STAR Program Research Presentations
Global consumption of materials and energy is accelerating. The rate of plant and animal species extinction is accelerating. On a finite Earth with a growing population, current consumption cannot continue sustainably. Greenhouse gases (GHGs) tell us an important part of this story. The Global Greenhouse Gas Reference Network, managed by scientists at NOAA’s Earth System Research Laboratory, is the largest greenhouse gas analysis network in the world. It has been shaped by scientific questions, stagnant funding despite rises in research costs, and the task of understanding how the Earth system will respond to a changing climate. The Network began by …

Nutrient Removal & Greenhouse Gas Abatement With Co2 Supplemented Algal High Rate Ponds, Ian Woertz, Laura Fulton, Tryg Lundquist
Civil and Environmental Engineering
High rate algae ponds fed clarified domestic wastewater and CO2-rich flue gas are expected to remove nutrients to concentrations similar to those achieved in mechanical treatment technologies, such as activated sludge. However, the energy intensity of wastewater treatment with CO2-supplemented high rate ponds (HRPs) would be less than that of mechanical treatments. In conjunction with anaerobic digestion of algal biomass and co-substrates, the algae-based system would produce a substantial excess of electricity. Greenhouse gas abatement from such CO2-HRP/digestion systems would stem mainly from energy conservation and the offset of fossil fuel electricity with biogas-derived …
