Absstract of: US2022154978A1

The disclosed technology includes methods of extracting geothermal energy, generally comprising the steps of: insertion of a thermal mass into a Heat Absorption Zone, absorbing heat in thermal mass, raising the thermal mass to a Heat Transfer Zone, and transferring the heat from the thermal mass. The acquired heat can be used to generate electricity or to drive an industrial process. The thermal mass can have internal chambers containing a liquid such as molten salt, and can also have structures facilitating heat exchange using a thermal exchange fluid, such as a gas or a glycol-based fluid. In some embodiments, two thermal masses are used as counterweights, reducing the energy consumed in bringing the heat in the thermal masses to the surface. In other embodiments, solid or molten salt can be directly supplied to a well shaft to acquire geothermal heat and returned to the surface in a closed loop system.

ELLISON ENV SERVICES LTD [GB]

GB_2600686_PA

Absstract of: WO2022090687A1

The present invention provides a testing apparatus and an associated method for assessing the performance and integrity of a ground source heat exchanger installation. The testing apparatus is configured to form a fluid tight, pressure resistant connection with the pipework of a ground source heat exchanger so as to create a test system. Fluid can then be pumped through the test system as the flow rate and/or fluid pressure are measured. By collecting this data about the fluid before and after it passes through the pipework the testing apparatus enables an operator to identify differences in the upstream and downstream values that may be indicative of a fault in the pipework. Preferably, fluid is circulated through the pipework in a first flow direction and then a second flow direction and measurements collected for both are compared to provide further detail of possible faults in the pipework.
