TEVERRA Highlights Subsurface Thermal Energy Storage at IRENA Dialogue on Green Data Centers in Malaysia

October 2026 | Atlanta, Georgia

TEVERRA's founder and President, Dr. Hamed Soroush, participated in an international technology dialogue organized by the International Renewable Energy Agency (IRENA), through its Alliance for Industry Decarbonization (AFID) and Utilities for Net Zero Alliance (UNEZA), to explore solutions for supporting the rapid growth of green data centers in Malaysia.

Held on October 22, 2026, the dialogue brought together renewable energy developers, technology providers, utilities, and industry stakeholders to identify critical technology gaps and practical pathways toward more sustainable data center infrastructure.

A central message of the discussion was that meeting the rapidly growing electricity demands of artificial intelligence requires more than expanding power generation capacity. Improving energy efficiency, particularly in data center cooling, must be an equally important priority.

During the discussion, Dr. Soroush highlighted the potential of ResStor™, a subsurface thermal energy storage technology developed by TEVERRA and being commercialized by EnEarthia, to significantly reduce data center cooling electricity and water demand.

By utilizing underground reservoirs as large-scale thermal storage resources and heat sinks, ResStor offers an innovative approach to cooling that can reduce reliance on conventional energy- and water-intensive cooling systems.

"Every megawatt saved on cooling is a megawatt available for computing," said Dr. Soroush. "As AI infrastructure expands, we need to focus not only on generating more electricity but also on using the energy we already have far more efficiently."

Advancing Integrated Solutions for Green Data Centers

The dialogue identified three important technology priorities: grid stability, efficient cooling, and digital innovation.

Participants also emphasized several considerations for accelerating green data center development, including:

• Energy efficiency first: Reducing electricity demand before expanding supply.

• Reliable clean energy verification: Strengthening transparency through hourly matching, geographical correlation, and additionality.

• Project bankability: Addressing contract structures, demand growth, and risk allocation to attract investment.

• Integrated infrastructure: Combining renewable generation, energy storage, efficient cooling, and grid technologies to deliver reliable and sustainable operations.

Subsurface thermal energy storage was highlighted as one of the promising approaches to reducing cooling-related electricity and water demand.

TEVERRA's participation reflects its commitment to advancing geothermal energy, subsurface engineering, and innovative thermal energy technologies that support the global energy transition.

Through the development of ResStor and its broader subsurface technology portfolio, TEVERRA continues to explore opportunities to improve energy efficiency, strengthen infrastructure resilience, and support the sustainable expansion of energy-intensive industries.

The outcomes of the IRENA dialogue are expected to contribute to a white paper outlining priority recommendations for green data center development, scheduled for publication by AFID and UNEZA by the end of 2026.

TEVERRA thanks IRENA, AFID, UNEZA, and the participating organizations for facilitating this important international discussion.
