The presentations from the annual Peer Review of US DOE funded geothermal projects are now posted online. AZGS presented the progress and results on the National Geothermal Data System we run on behalf of the Association of American State Geologists. NGDS is in a beta test mode, with over 17,000 data sets comprising more than 5 million records currently. That number is expected to double or triple by year end.The Geothermal Technologies Office funds 154 research and development projects leveraging nearly $500 million in total combined investment, and 95 of the those projects presented at the annual Peer Review event. Each project represents a growing technology sector in conventional hydrothermal, low-temperature and co-produced, or Enhanced Geothermal Systems (EGS) technologies, as well as technical and non-technical research and analysis.
Each year, DOE requires a rigorous review of investments by independent, qualified peers to assess key achievements in geothermal development and to meet strategic DOE guidelines. Peer Review offers geothermal stakeholders an opportunity to learn about the projects funded by DOE across a wide spectrum of technical complexity and funding magnitude, from research and development to demonstration and analysis. The event also opens a dialogue with other respected researchers in geophysics, geochemistry, modeling, tools, and more.
The announcement says "Glen Canyon Dam,
completed in 1964, is anchored in Jurassic Navajo Sandstone, the oldest
formation exposed in the map area. Jurassic and Cretaceous strata are
cut by a few small faults and warped by broad shallow folds. Surficial
deposits consist of extensive river and stream terrace gravel, eolian
sand, and minor alluvium and talus. The map is based on new field
mapping and aerial photograph interpretation and is provided as two
plates in PDF format with a 12-page explanatory booklet that describes
map units."
Arizona mining companies are having a hard time finding qualified candidates for even high paying jobs, and that's symptomatic of the industry nationwide.
