GLJ’s dedicated in-house geothermal team works with our clients to support the implementation and evaluation of geothermal resources for heat and power applications. We provide independent 3rd party evaluations for geothermal assets which can be used for public disclosure, fair market value assessment, asset transactions, financial reporting, investment decisions and legal proceedings. GLJ applies globally recognized geothermal classification systems to estimate reserves and resources.

Main reporting codes:

  • United Nations Framework Classification (UNFC) for Geothermal Resources (2016)
  • CanGEA Canadian Geothermal Code for Public Reporting
  • Australian Geothermal Energy Association (AGEA) – The Geothermal Reporting Code

NI51-101 Reporting is applicable if Geothermal is related to Oil and Gas

Our comprehensive market assessments provide invaluable insights into geothermal electricity and heat. Through detailed geothermal technology reviews and thorough evaluations of geological potential, we uncover the untapped opportunities in this renewable energy sector. Additionally, our assessments include in-depth analyses of power and heat markets, considering regulatory frameworks and limitations. Whether you are a company exploring geothermal opportunities, government or regulatory organization, investor or financial stakeholder, our market assessments equip you with the knowledge and confidence to navigate the dynamic landscape of geothermal energy. Let’s collaborate to unlock the immense potential of geothermal energy together, paving the way for a greener and more sustainable future.

GLJ supports geothermal technology startups, future stakeholders and established industry leaders by conducting independent technological reviews on emerging geothermal innovations.

Two transformational unconventional geothermal technology pathways have emerged:

  • Advanced Geothermal Systems (AGS), which utilizes conduction instead of producing liquid to extract heat. This unlocks the potential of “Geothermal Everywhere,” which expands the scope of geothermal resources.
  • Enhanced Geothermal Systems (EGS) and Super Hot Rock Geothermal, which create fracture networks to collect heat from the Earth, in some cases at supercritical temperatures and pressures.

Through comprehensive assessments, GLJ ensures these new geothermal technologies are scrutinized for technical feasibility and commercial viability to meet your project needs.
