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.

Phosphoric acid production costs?
Phosphoric acid production costs are $500-900/ton, for a 10% IRR on a new facility, with $1,000-2,000/Tpa of capex. This is using the ‘wet process’, where phosphate ores are reacted with sulfuric acid. CO2 intensity is 0.6 tons/ton. However, the numbers depend on product purity. There is also a 10x higher carbon, yet potentially lower-cost process,…

Electric vehicle: battery life?
Electric vehicle battery life will realistically need to reach 1,500 cycles for the average passenger vehicle, 2,000-3,000 cycles after reflecting a margin of safety for real-world statistical distributions, and 3,000-6,000 cycles for higher-use commercial vehicles. This means lithium ion batteries may be harder to displace with novel chemistries?

LNG plant compression: gas drives vs electric motors?
This data-file compares the costs of refrigerant compression at LNG plants, using gas turbines, electric motors powered by on-site CCGTs, or electric motors powered by renewable electricity. eLNG has higher capex costs, but higher efficiency, lower opex, and short payback times. Numbers in $/mcf and $/MTpa can be stress-tested in the data-file.
