Thermal energy storage: heat of the moment?
…excess renewable energy, converting it to heat, then heating up a thermal storage medium in some kind of well-insulated tank. The heat can be re-released later. Either directly, or via…
Leading Companies Commercialising Heat Pumps?
Heat pumps can halve the CO2 intensity of residential heating while also lowering costs by c10-35% in some cases. This all creates an exciting opportunity for heat pumps in the…
LNG liquefaction technologies: an overview?
…heat exchangers, which can be more efficient but more expensive than plate fin heat exchangers. Our model assumes 87% net efficiency transferring coldness from the refrigerant into the LNG stream….
Heat pumps: hot and cold?
Some policymakers now aspire to ban gas boilers and ramp heat pumps 10x by 2050. In theory, the heat pump technology is superior. But in practice, there are ten challenges….
Decarbonize Heat?
…prices. Heat pumps can be cost-competitive, if powered from the grid, and our screen of leading heat pump companies is presented on page 6. Running heat pumps purely off of…
Organic Rankine Cycles: the energy economics?
…heat recovery in combination with heat exchangers, or to generate electricity from lower-temperature energy sources such as geothermal. Europe started building ORC plants in the 1980s, and now has 120-150…
Thermal power plant: loss attribution?
…and two-thirds of the exhaust gas waste heat is recaptured via heat-exchangers (e.g. warming up input air, fuel and cold water entering the boilers). Without this heat recovery, the thermal…
Refrigerants: leading chemicals for the rise of heat pumps?
What chemicals are used as refrigerants? This data-file is a breakdown of the c1MTpa market for refrigerants, across refrigerators, air conditioners, in vehicles, industrial chillers, and increasingly, heat pumps. The…
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…
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…
