Alessandro F. Rotta Loria, Ph.D.
Chief Executive Officer & Co-founder
Alessandro Rotta Loria is an engineer, scientist, inventor, and entrepreneur committed to unlocking the energy potential of the underground and transforming the subsurface into an active component of sustainable buildings, infrastructures, and cities. Throughout his career, he has worked across the boundaries of academia and engineering practice to advance how geothermal energy harvesting and storage technologies are understood, designed, and deployed. His contributions span the development of new concepts for underground thermal energy harvesting and storage, the creation of analysis, prediction, and design tools for advanced geothermal systems, and their installation into buildings and major infrastructure projects.
Combining scientific expertise with hands-on experience in engineering, consulting, entrepreneurship, and technology transfer, Alessandro has contributed to bringing innovative geothermal solutions from concept to real-world application. A central theme of his work is the use of underground structures and spaces not only for their conventional functions, but also as energy assets capable of harvesting, exchanging, storing, and supplying thermal energy. His vision is to make the subsurface a fundamental part of the clean-energy transition—turning the ground beneath cities and territories into an accessible, distributed, and largely untapped source of sustainable energy.

What we do
We harness the world beneath our feet—the subsurface—to provide buildings, infrastructures, and cities with clean thermal energy, 24/7, irrespective of the weather, and everywhere on earth. The core of our activities focuses on the conceptual development, analysis, design, monitoring, and optimization of shallow geothermal technologies, including vertical and horizontal boreholes, as well as thermally activated underground structures and infrastructures, including energy piles, energy walls, energy slabs, and energy tunnels. Our work also addresses deeper geothermal technologies, including geothermal plants for power production, as well as underground and aquifer thermal energy storage systems. In a nutshell, we are experts in harnessing and repurposing underground energy to meet the massive energy demand of the built environment and decarbonize its carbon footprint.

Our vision
Our total approach strives to establish sustainable built environments through affordable and demonstrated underground energy solutions that transform today the cities of tomorrow. These solutions can sense and react to the needs of people while harnessing and storing clean energy through the underground for the benefit of humanity and the world—across individual buildings, neighborhoods, and entire cities. We envision a world where the underground plays a central role in energy harvesting, storage, and conversion.
