Energy needed to produce steam: enthalpy and entropy data?
…1-bar (i.e., 1 atmosphere), it takes 4.2 kJ of energy to heat each kg of water by each 1◦C (aka the specific heat capacity of water). So it might require…
Industrial heat: the myth of electrify everything?
…of water and steam make this industry one of the least heat-efficient globally. Heat exchangers and heat pumps can help. But they may actually increase CO2 intensity if electricity replaces…
The laws of thermodynamics: what role in the energy transition?
…cooler reservoir. Entropy is the ratio of heat energy flux to absolute temperature. When the heat energy leaving the heat source divided by the absolute temperature of that heat source…
Heating-melting: how much energy is needed?
How do we quantify the minimum energy needed to heat materials and melt materials? This data-file calculates values, in kWh/ton, from first principles, based on target temperatures, specific heat capacities…
Illustrating industrial energy efficiency in the context of cooking?
…has efficiently transferred heat into the food, but it was not useful heat in the sense of achieving a desired outcome. If the dish is ruined, then all prior heat…
Decarbonize Heat?
Natural gas currently fuels two-thirds of residential and commercial heating, which in turn comprises c10% of global CO2. We have assessed ten technologies to decarbonize heat, including heat pumps, renewables,…
Energy Recovery Inc: pressure exchanger technology?
…End markets for pressure recovery based on patents filed by Energy Recovery Inc. Refrigeration, air conditioning and heat pumps are seen as a growing source of demand. One patent notes…
Machine Learning to Optimise Rod Pumps
…production uplifts using machine learning to optimise 300 wells at the Bahrain oilfield. Hence we constructed a simple model for digitising rod pumps: we estimate $100k of NPV can be…
Post-combustion CCS: what energy penalties?
…much waste heat can be harnessed at a solid fuel power plant? A typical thermal power plant must already be recapturing 50-70% of its theoretically available waste heat if it…
