Hot Dry Rock

Hot Dry Rock

Hot crystalline rock with essentially no porosity and lacking producible hot water. Geothermal production from hot dry rock reservoirs is the primary goal of EGS (enhanced geothermal system) research in which cold water is injected and hot fluid is produced.

Word of the Week – Conduction

Word of the Week – Conduction

Conduction For geothermal applications, this refers to heat transfer in solids where thermal energy flows via microscopic-submicroscopic collisions of particles, which at a macro level is seen as solid-state diffusion. A vertical conductive thermal gradient is linear...

Word of the Week – Convection

Word of the Week – Convection

Convection Refers to heat transfer by fluid circulation in permeable rocks where thermal energy is transported with the flow of hot fluid (water or steam).

Word of the Week – Cooling Tower

Word of the Week – Cooling Tower

Cooling Tower Plant equipment that is used to dissipate heat into air rather than into a river. Cooling is induced in two different ways. For binary plants, dry cooling towers use fans to draw air across a heat exchanger and this removes heat from a working fluid...
