Energy needed to produce steam: enthalpy and entropy data?
This data-file quantifies the energy needed to produce steam, for industrial heat, chemicals, CCS plants and hydrogen reforming? As rules of thumb, low pressure saturated steam at 100◦C requires 2.6 GJ/ton (720kWh/ton), medium pressure dry steam at 6-bar and 300◦C requires 3 GJ/ton (830kWh/ton) and super-critical steam at 250-bar and 600◦C requires 4 GJ/ton (1,150kWh/ton).

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 and latent heat capacities. A good rule of thumb is 25 kWh of useful energy to heat each ton of material by each 100ºC.

Decarbonize Heat?
Natural gas fuels two-thirds of residential and commercial heating, which in turn comprises c10% of global CO2. We assessed ten technologies to decarbonize heat, including heat pumps, renewables, biogas and hydrogen. The lowest cost solution is to double down on natural gas with nature-based carbon offsets. Global gas demand for heating should continue rising.

Energy Recovery Inc: pressure exchanger technology?
Pressure exchangers transfer energy from a high-pressure fluid stream to a low-pressure fluid stream, and can save up to 60% input energy. Energy Recovery Inc is a leading provider of pressure exchangers, especially for the desalination industry, and increasingly for refrigeration, air conditioners, heat pump and industrial applications. Our technology review finds a moat.

Machine Learning to Optimise Rod Pumps
This data-file summarises progress using machine learning to maximise production from mature wells, by detecting errors and optimising production. There is potential to lower global decline rates by c100kbpd per annum for over a decade, and increase each well’s NPV by $0.1M.

Turbochargers: leading companies?
Six leading companies in turbochargers control two-thirds of the $15-20bn pa global turbochargers market. 55% of ICE vehicles now have turbochargers, which can improve fuel economy my as much as 10%, by enabling smaller and better utilized engines to achieve higher peak power ratings. What opportunities ahead, to adapt for vehicle electrification, or even if…

Air conditioning: energy demand sensitivity?
This data-file quantifies air conditioning energy demand. In the US each 100 variation in CDDs adds 26 TWH of electricity (0.6%) demand and 200bcf of gas (0.6%). Air conditioning already consumes 7% of all global electricity and could treble by 2050.

Demand shifting: electrical flexibility by industry?
Demand shifting flexes electrical loads in a power grid, to smooth volatility and absorb more renewables. This database scores technical potential and economical potential of different electricity-consuming processes to shift demand, across materials, manufacturing, industrial heat, transportation, utilities, residential HVAC and commercial loads.

Thermal power plant: loss attribution?
This data-file is a simple loss attribution for a thermal power plant. For example, a typical coal-fired power plant might achieve a primary efficiency of 38%, converting thermal energy in coal into electrical energy. Our loss attribution covers the other 62% using simple physics and industry average data-points.
