Estimating global, on-shore potential for power from wind

Experts say wind power has the potential to supply a much larger portion of global energy. But how much more? PNNL scientists used higher-resolution, on-shore wind speed data to estimate how much power wind could provide regionally and globally, and at what cost. They also investigated the uncertainties that surround wind supply estimates, such as land use suitability, turbine cost and financing assumptions. For example, estimates can vary greatly based upon how land suitability is measured, such as the assumed amount of cropland that can be used for wind development. Less impactful to the estimate is the cost of connecting wind resources to the existing transmission grid. PNNL's Yuyu Zhou and his team will present a poster that explains the research and results.

GC41D-0861: Global Onshore Wind Energy Potential and Its Uncertainties. Dec. 8, 8 a.m. - 12 noon, Moscone South, Halls A-C. Media contact: Annie Haas, anne.haas@pnnl.gov, (509) 375-3732.

Getting to know the in-betweens of carbon sequestration

A new kind of nuclear magnetic resonance analysis can help scientists better evaluate the potential of underground sites to safely sequester greenhouse gas carbon dioxide emissions. The technique, called high-pressure magic angle spinning NMR, allows researchers for the first time to understand the details of the multi-step chemical reactions that turn supercritical carbon dioxide into solid mineral compounds in situ, or under the same conditions that they would occur underground. Those details include identifying the reaction intermediates, which could help evaluate how well specific si
