Systems Analysis Geothermal Regulatory Roadmap for more information on Systems Analysis, visit the GTO website or contact geothermal@ee.doe.gov. User Testing at the Geothermal Energy Association’s annual Expo provided valuable feedback to Dr. Sam Zheng, a senior research scientist with Siemen’s Corporate Research, and GTO’s Data Steward and Technology Manager Arlene Anderson. “We have started working on the low-hanging fruit fixes,” said Zheng. User Interface Testing at the Geothermal Energy Expo Geothermal Prospector A team at the NREL has developed a Geothermal Prospector tool to provide data exploration and spatial analysis capabilities that support geothermal exploration. This application will be updated in 2014 to allow users to launch the Geothermal Prospector directly from NGDS datasets compliant with the Open Geospatial Consortium, a network of standard coding that enables interoperability among and between diverse geospatial data stores, providers, and applications. The Prospector will provide access to visualization and analysis capabilities for NGDS data. This new capability will also provide an opportunity to test and validate data listed in the NGDS. This year, the GTO NGDS team—Arlene Anderson, Dave Cuyler, and Jodi Deprizio—met with Dan Getman and his Data & Visualization staff to foster a partnership on geothermal mapping. NREL’s Geothermal Prospector Team (above), led by Dan Getman, has released a helpful tool to navigate the NGDS.

International Collaborations Since the inception of geothermal energy development at DOE in the 1980s, the Geothermal Technologies Office has partnered with international organizations to improve science and engineering knowledge within the geothermal sector and promote education and information sharing worldwide. Asian and European organizations are active in EGS research and have funded long-term investigations with backing from the public and private sectors. In fact, government investment from the United Kingdom, Japan, and Germany helped to underwrite research that led to breakthroughs in EGS. This ongoing collaboration has yielded mutual benefits—under the framework of the International Energy Agency’s Geothermal Implementing Agreement, signed in 1996—by facilitating technological advancements, avoiding duplication, and leveraging limited resources. Collaboration with international scientists involved in similar R&D continues to be a key component of the Energy Department’s EGS R&D strategy. Recent cooperation between the United States and Japan led scientists at Kansas State University to collaborate with Japanese researchers to plan flow tests at the Hijiori, Japan research site. The results at Hijiori and at Fenton Hill, New Mexico strongly suggest that better imaging of fluid flow and temperature distribution in EGS reservoirs could dramatically improve injection and production well performance. The research in superresolution seismic imaging using time-lapse vertical seismic profiling and micro-earthquake data— undertaken at Los Alamos National Laboratory—has spurred field testing internationally. Jay Nathwani, GTO’s chief engineer, facilitates international collaborations for the program. 23 The Raft River geothermal site, now commercially owned and operated, was formerly an Energy Department demonstration field site, where research investments yielded a deployable geothermal operation. Today, Energy Department EGS demonstrations are still tested adjacent to the operating hydrothermal field. Regulatory Roadmap Spurs Geothermal Energy Development At this year’s annual meeting of the Geothermal Resources Council in early October, the GTO conducted user testing of the NGDS in preparation for its scheduled deployment in 2014. The Geothermal Energy Association’s concurrent Expo was the perfect venue to gain feedback on the NGDS. At the NGDS exhibit booth, visitors from industry, research, and government tested both end-user and data- consumer viewpoints. Test scenarios covered map, library, and faceted searches, user ratings, resources, and tools. The NGDS design team received a solid day’s worth of input to help improve the NGDS functionality. Dr. Sam Zheng, a senior research scientist with Siemens Corporate Research of Princeton, New Jersey, also conducted similar user testing last year at the Stanford Reservoir Engineering Workshop and at GEA’s Expo. This latest round of input is much improved. The new data system received both positive feedback and practical suggestions for optimizing the network. Participants indicated the system was easy to use and that they would access the NGDS frequently once it is up and running. They found the search options easier than typical library searches and gave feedback in key areas: replacing the Data Watch section with more relevant data, linking the main image to Geothermal News, enhancing images, and changing Resources to a Tools tab—a dynamic page where users will be able to upload their own application for analyzing data. Overall, this third tier of user testing met with very positive feedback and applicable recommendations that will further streamline the NGDS user experience. In an Energy Department report published in 2011, industry stakeholders identified the permitting timeline as a major barrier to increasing geothermal power plant development. To address this concern, the GTO collaborated with NREL to create a Geothermal Regulatory Roadmap that will help developers navigate regulatory requirements at every level of government to deploy geothermal energy projects. In partnership with the Bureau of Land Management, U.S. Fish and Wildlife Service, and U.S. Forest Service, NREL convened key federal, state, and local permitting officials, along with industry representatives, to identify potential opportunities for streamlining the efficient and responsible development of geothermal energy in the United States. The roadmap will help strengthen collaboration between federal and state agencies, speed the review of proposed projects, and implement steps that advance efficient and responsible evaluation. Streamlining the permitting process also helps lower development costs and reduces financial risk for utilities. The roadmap includes distinct flowcharts that address all federal and state regulatory requirements for developing a geothermal resource—from land use and leasing plans, to drilling exploratory wells, to developing a geothermal power plant. These comprehensive flowcharts have now been completed for ten geothermal- rich states: Alaska, California, Hawaii, Idaho, Montana, Nevada, Oregon, Utah, Colorado, and Texas. The roadmap is now available, and also includes links to permit application forms, policies, and supporting documents. Permitting resources for the first tranche of states are now complete and available and can be accessed on the Tools and Resources page of this report.
