Geothermal Developer Ignis H2 Energy Raises $12.5M in Series a First Close

Ignis H2 Energy Inc. (“Ignis Energy”), a geothermal exploration and development startup, announced today the successful first closing of its Series A funding round, securing $12.5 million from a consortium of investors, including leading funds and private individuals. The funding round was led by alfa8 and includes a commitment from drilling contractor Nabors Industries, alongside investments from existing shareholders, private individuals, and family offices.

Advancing a Global, Risk-Balanced Geothermal Portfolio

Unlike other startups in the geothermal industry, Ignis Energy does not rely on a single technology or opportunity. Instead, it manages a risk-balanced portfolio of geothermal power-producing opportunities across high-enthalpy environments worldwide. By leveraging proven technologies and insights from a distinguished panel of geothermal experts, Ignis Energy diversifies risk while ensuring a steady pipeline of sustainable energy projects. The company has already secured promising geothermal opportunities in Turkey, Alaska, California, Nevada, and Italy.

Driven by a mission to provide affordable, reliable, and sustainable baseload geothermal energy, Ignis Energy integrates extensive expertise from the oil and gas sector into geothermal exploration and development. The company is pioneering the use of cutting-edge machine learning models to predict, locate, and explore geothermal resources more efficiently, leading to better drilling outcomes and lower project risk.  With a portfolio spanning multiple geographies and geological formations, Ignis Energy is targeting the development of one gigawatt of documented producible geothermal reserves by 2030.
