Spike Renewables is designing and manufacturing technological components to consolidate the operational flexibility of geothermal plants and reduce the problems of silica deposition.
The GEOFLEXHEAT research project aims to further develop the silica retention system in geothermal frost before re-injection into the well. This solution will reduce the re-injection temperature and recover valuable minerals such as silica for further industrial use.
The activities are part of the GEOFLEXheat project co-funded by the EC within the H2020 framework programme.
GEOFLEXheat abstract:
The GEOFLEXheat project aims to revolutionize the European geothermal energy sector by introducing an innovative suite of technologies to enhance the extraction, efficiency and application of geothermal heat across diverse industrial sectors. This initiative is driven by a consortium that synergizes leading research institutions, SMEs, and industry experts to tackle the challenges of scalability, integration, and social acceptance associated with geothermal systems. At the core of project lies the development of a Heat Pipe Heat Exchanger coupled with an advanced Scaling Reactor to improve heat recovery from geothermal brine while simultaneously providing valuable mineral byproducts. This is complemented by a novel High-Temperature Heat Pump that delivers cost-effective and high-temperature heat, crucial for a wide range of industrial processes and beyond. The project will also deliver a state-of-the-art Control Strategy and Digital Twin, optimizing system performance and enabling real-time management of
geothermal plants. Through comprehensive simulation and modelling, the project will showcase the full potential of geothermal energy to provide stable, affordable, and sustainable heat supply. The ambitious goals include fostering Europe’s global leadership in renewable technologies, ensuring reliable energy supply for industries and households, and accelerating the integration of Carbon Capture, Utilization, and Storage with geothermal systems. To ensure the project’s outcomes have a lasting impact, GEOFLEXheat will execute robust commercialization strategy, including the establishment of a spin-off company, extensive environmental and economic assessments, and the creation of a Social Acceptance Guide to facilitate policy influence and community engagement. Embracing a future where geothermal energy is a cornerstone of Europe’s renewable energy mix, GEOFLEXheat is poised to become a catalyst for energy sustainability, economic growth and environmental stewardship.
