Geothermal Technical Working Papers:
Interagency Collaboration with DOE's Geothermal Technologies Office and DOI's Bureau of Land Management

The Department of Energy's (DOE) Geothermal Technologies Office (GTO) and the Department of the Interior's (DOI) Bureau of Land Management (BLM) committed to develop and implement a formalized working agreement that will facilitate a technical evaluation of environmental impacts of geothermal technologies. This analysis will provide a comprehensive reference document which can form an analytical basis for future agency National Environmental Protection Act (NEPA) documents. The analysis will take the form of technical working papers that will be integrated into the NEPA processes of participating Agencies via internal mechanisms: BLM could issue an Instruction Bulletin/Memorandum; and DOE could issue guidance documents to Program and Field Offices. Technical working papers have been drafted for the following five topics:

  • Pre-production Drilling
  • Production Drilling
  • Downhole Fluids
  • Produced Fluids
  • Hydraulic Stimulation

These papers are currently under Agency review and will be available for public comment upon completion.

There is enormous untapped potential for geothermal. It is a renewable and diverse energy solution for the United States—providing reliable and flexible electricity generation and delivering unique technology solutions for America's heating and cooling demands. Geothermal resources can be found nationwide, are "always on," and represent vast domestic energy potential. Only a fraction of this potential has been realized, however, because of technical and non-technical barriers that constrain industry growth. For example, through regulatory reforms alone, geothermal capacity could double. With technology improvements that focus on exploring, discovering, developing, and managing geothermal resources, geothermal electric power generation could increase nearly 26-fold from today.

Increasing Geothermal Electricity Generation 26-Fold by 2050

To evaluate the potential for geothermal energy to contribute to America’s energy future, the U.S. Department of Energy’s Geothermal Technologies Office initiated the GeoVision analysis—a detailed research effort to explore opportunities for increased geothermal deployment and the pathways necessary to overcome technical and non-technical barriers to such deployment. The analysis evaluated opportunities for successful geothermal deployment based on three key objectives:

  • Increased access to geothermal resources
  • Reduced costs and improved economics for geothermal projects
  • Improved education and outreach about geothermal energy.

The GeoVision analysis used rigorous quantitative models to assess geothermal deployment potential under scenarios that considered a range of technologies, market conditions, and barriers. The analysis determined that achieving all three key objectives can reduce risk and costs for geothermal developers, increase growth potential for geothermal energy, and provide the United States with secure, flexible energy that offers economic benefits to the geothermal industry and environmental benefits nationwide. The analysis projected that, through technology improvements, geothermal electricity generation capacity has the potential to increase to more than 60 gigawatts by 2050—providing 8.5% of all U.S. electricity generation.

Benefits of Geothermal Energy

To realize geothermal energy's full potential, stakeholders must reduce risk and costs by overcoming significant technical and non-technical barriers. The GeoVision analysis calculated the opportunities for increasing geothermal deployment by reducing these barriers. Such increased deployment can leverage the capabilities and unique features of geothermal energy, including:

  • Secure, "always-on" renewable electricity generation with flexible and load-following capabilities that provide essential services to support the grid of the future
  • Nationwide, affordable solutions for electricity generation and for heating and cooling at residential, commercial, and district levels
  • Existing commercial technologies that are already proven in the market, augmented by innovative technologies with vast potential to increase electricity generation and heating and cooling solutions
  • Economic benefits to the geothermal industry and environmental benefits for the nation
  • Revenue potential for federal, state, and local stakeholders, as well as royalty potential for leaseholders.

The GeoVision analysis confirmed that improving the tools, technologies, and methodologies used to explore, discover, access, and manage geothermal resources would reduce costs and risks associated with geothermal developments and facilitate access to previously untapped sources of geothermal energy. In addition, optimizing permitting timelines alone could double geothermal capacity by 2050.

Data Provision Instructions for All DOE Geothermal Technologies Office Funds Recipients


As required by DOE Geothermal Technologies Office (GTO) Funding Opportunity Announcements for Financial Assistance awards, all GTO funds recipients including national laboratories must provide data to the DOE Geothermal Data Repository (DOE-GDR).  In most cases, performers provide data to the DOE-GDR no later than the end of the quarter in which the data are generated. 


The data must be sufficiently complete, in a format acceptable to DOE, and include all files required for an independent analyst to reproduce and verify the work.  The data will be submitted to DOE-GDR at  While most data formats may be uploaded to the DOE-GDR, DOE prefers reusable, structured data that supports conclusions communicated in project quarterly and other reports. Use of National Geothermal Data System (NGDS) data exchange models is highly encouraged. For example, data generated from rare earth element analysis may be entered into a NGDS aqueous chemistry structured format available at

The data will be made publicly available via the NGDS once they have been submitted and accepted into the DOE-GDR system.  If the data are protected or subject to a moratorium, they will not be made publicly available until the moratorium has expired, and they will be held in a secure section of the DOE-GDR.  Protected Data will be treated according to the Intellectual Property Provisions.



You must register for an account at the data submission site prior to submitting any data. Registration establishes a user account with ID and password, and authorization to submit data to the DOE-GDR. Visit the DOE-GDR website at to initiate your account registration and perform all actions associated with data submission. For technical assistance with the registration or data submission interface, contact GDR Help at


Once registered, you must log into the data submission site at to submit data. You must complete the data submission form for each data resource (e.g. excel file, word document, pdf, or data containment software), including:


•  Provide appropriate metadata and contact information
•  Agree to the data handling terms of the DOE-GDR
•  Specify the release date for any Protected Data (if applicable), consistent with your Intellectual Property Terms
•  Attach the data

After your data have been submitted, you will not be able to edit them for the duration of the review and curation process. It is recommended that you retain a copy of the submitted data.
For information and assistance concerning preparation of data files, metadata, unique data requirements, and the data curation process, contact GDR Help at or visit


Data submitted to the DOE-GDR and identified as “Protected Data” are subject to the terms and conditions set forth in your Intellectual Property Terms incorporated into your Award. During the period prior to the public release date, Protected Data are held in a secure data store with restricted access pursuant to the Intellectual Property Provisions.  All other data will be made publicly available via the NGDS once they have been submitted and accepted into the DOE-GDR system.


You may cancel a submission at any time prior to public release. Cancellation will terminate the curation process and remove any copies of the originally submitted data from the system. If you wish to edit data or metadata after submission, you will need to cancel and resubmit.

Specific questions pertaining to your award should be addressed to the DOE Technical Project Officer.
