Generation of electricity and hydrogen from geothermal energy

Important results from the project

The project has created a 3D model for a thermosyphon system for generating electricity from geothermal energy. Fluid flow, heat distribution and pressure were simulated in different geometric shapes. Support for various systems for electricity production and hydrogen has been produced and compiled, with a focus on electricity production via various thermodynamic cycles. Finally, a "freedom-to-operate" analysis has been performed for the patent area. Over 1000 patents were found and researched. Of these patents, non were identified as obstacles for future business operation.

Expected long term effects

1. To develop a simulation model for the heat flow. The goal has been met and a simulation model for the heat flow has been established. 2. To develop system components for the generation of electricity and hydrogen. The goal has been met and system components have been developed for two different cycles, “Organisk Rankine Cycle” (ORC) and Stirling bicycle for electricity production and hydrogen through electrolysis. 3. To get a clear picture of the patent area. The goal has been met and over 1000 relevant patents have been searched where none proved to be an obstacle.

Approach and implementation

Consultants with knowledge of CFD analysis were hired to carry out the simulation of the 3D model and to develop system components for electricity production and hydrogen through electrolysis. The project was able to show that it is possible to generate a thermosyphon flow that could be suitable for electricity production with the help of system components from an “Organisk Rankine Cycle” and from a Stirling cycle type. A patent engineer was hired to review the patent area. Out of over 1,000 patents, no obstacles were found, which facilitates future development of the system.
