Chlor-alkali process: the economics?
This data-file captures chlor-alkali process economics, to produce 80MTpa of chlorine and 90MTpa of caustic soda. Our base case requires $600 per ecu for a 10% IRR and a growth project costing $600/Tpa. Electricity is 45% of cash cost. CO2 intensity is 0.5 tons/ton. Interestingly, chlor-alkali plants can demand shift.

Solar costs: four horsemen?
Solar costs have deflated by an incredible 90% in the past decade to 4-7c/kWh. Some commentators now hope for 2c/kWh by 2050. Further innovations are doubtless. But there are four challenges, which could stifle future deflation or even re-inflate solar. Most debilitating would be a re-doubling of CO2-intensive PV-silicon?

Energy economics: an overview?
This data-file provides an overview of energy economics, across 175 different economic models constructed by Thunder Said Energy, in order to put numbers in context. This helps to compare marginal costs, capex costs, energy intensity, interest rate sensitivity, and other key parameters that matter in the energy transition.
