Thermal energy storage: leading companies?
This data-file is a screen of thermal energy storage companies, developing systems that can absorb excess renewable electricity, heat up a storage medium, and then re-release the heat later, for…
Enhanced geothermal: digging deeper?
…hinging on the enthalpy of hot fluids (page 8), avoiding the energy costs of pumps (page 9) via thermosiphons (page 10), prioritizing heat rather than Rankine cycle power (pages 11-12),…
Geothermal energy: costs and economics?
…electricity, and enhanced geothermal heat. The capex costs for geothermal draw on our models, which capture the costs of drilling wells, heat exchangers and Organic Rankine Cycles. Please download the…
Industrial heating technologies: an overview?
This data-file summarizes different heating technologies, predominantly electric heating technologies, used to supply process heat within industry. The file covers convection heating, infrared radiant heat, immersion coils, electric ovens and…
Established technologies: hiding in plain sight?
…budget was a major consideration). No amount of heating would make this property warm in the winter! For this reason, I have retained some skepticism about converting residential heat to…
AirJoule: Metal Organic Framework HVAC breakthrough?
…turn, is used to reject heat from air (about one-third of the total) and to reject heat from the inevitable condensation of water, as air cools down (about two-third of…
Cool customers: AI data-centers and industrial HVAC?
…as compressors, heat-exchangers, pumps, fans and blowers, storage tanks, piping, VFDs, switchgear, grid connections and engineering and construction. All of the capex ultimately goes somewhere. The economics of commercial cooling…
A new case for gas: what if renewables get overbuilt?
Overbuilding renewables may have unintended consequences, making power grids more expensive and less reliable. Hence more businesses may choose to generate their own power behind the meter, installing combined heat…
Global average temperature data?
…particularly complicated. It takes 80% as much heat to melt 1kg of ice as it takes to boil 1kg of water, which means that the surface temperatures above sea ice…
Gas turbines: what market size in energy transition?
Combined heat and power systems are 20-30% lower-carbon than today’s gas turbines, as they capture waste heat. They are also increasingly economical to backstop renewable-heavy grids. Amidst uncertain policies, the…
