EarthSafe sets the stage for a transformational leap in the exploration and assessment of deep geothermal energy and critical minerals. As humanity approaches the third energy transition, the demand for low-carbon and renewable energy sources is rising sharply, accompanied by a rapidly increasing need for critical minerals. Predictions suggest a quadrupling of the global supply of critical minerals by 2040, with the EU requiring up to 18 times more lithium, five times more cobalt, and 120 times more neodymium by 2030. The European Union’s dependency on imports for over 95% of these materials emphasizes the urgency for innovative exploration technologies.
At the same time, the EU’s commitment to reducing greenhouse gas emissions by 55% by 2030 and achieving net-zero emissions by 2050, as outlined in the European Green Deal, necessitates rapid shifts to alternative energy sources. Deep geothermal energy, particularly super-hot geothermal systems (≥ 400 °C), presents a promising solution for large-scale, continuous, and sustainable energy generation. However, limitations in current exploration and assessment technologies hinder the full realization of this potential.
Project Pathway to Impact
The EarthSafe project’s primary goal is to create transformational data-fusion platforms that integrate satellite and land-based datasets using cutting-edge Machine Learning (ML), probabilistic inverse theory, and computational modelling. These platforms will enable global and regional exploration of geothermal and mineral resources, provide pre-competitive data and models for greenfields and brownfields exploration, and support cost-efficient, globally applicable technologies to accelerate the transition to clean energy and green technologies.
EarthSafe aligns closely with the objectives of the European Green Deal, addressing both the decarbonization of energy systems and the reduction of social and regional disparities. By fostering innovation in exploration methodologies, the project supports achieving eight United Nations Development Goals (UNDGs), including clean energy (Goal 7), industry innovation (Goal 9), and climate action (Goal 13).
Political and Strategic Context
Recent geopolitical shifts, including the European response to energy disruptions in 2022, underscore the urgency of reducing reliance on fossil fuels and imported critical minerals. Investment in deep geothermal energy, projected to grow by over 60% in the coming decade, is pivotal to Europe’s energy strategy. However, the lack of reliable, large-scale exploration technologies remains a major barrier to unlocking these resources.
Scale and Significance of Expected Impacts
EarthSafe’s expected impacts are multi-dimensional. By advancing exploration capabilities, the project will support the development of deep geothermal reservoirs, providing a sustainable energy source with minimal environmental footprint. Its multidisciplinary approach positions Europe as a leader in sustainable exploration technologies while supporting vulnerable societies with new energy opportunities, addressing energy poverty and inequality.
Integration of Social Sciences and Humanities
Recognizing the importance of public perception and engagement, EarthSafe incorporates social sciences to analyse public perceptions of mineral and geothermal exploration, enhance science communication, and develop socially responsible practices for exploration and resource management. By addressing societal and ethical dimensions, the project ensures that technical innovations align with public acceptance and regulatory standards.
