Sandia progressing to demo stage with supercritical CO2 Brayton-cycle turbines; up to 50% increase in efficiency of thermal-to-electric conversion

Green Car Congress

There is a tremendous amount of industrial and scientific interest in supercritical CO 2 systems for power generation using all potential heat sources including solar, geothermal, fossil fuel, biofuel and nuclear. The S-CO 2 system is also very compact, meaning that capital costs would be relatively low. site of contractor Barber Nichols Inc.,

A closer look at why heat pumps are dominating EV HVAC systems

Charged EVs

In an EV, while using the HVAC won’t detract from the maximum output of the traction motor, it does still demand energy from the battery, so there will be a hit to range. Reality is never quite as ideal as theory predicts, but it is nonetheless true that COP for a heat pump is always higher when viewed from the hot side, rather than the cold.
