Absorption chillers: the economics?

This data-file approximates the costs of absorption chillers, which perform the thermodynamic alchemy of converting waste heat (e.g., from a CHP turbine) into coldness.

Today the market is small, around $6bn per annum. But we think systems like these could be increasingly useful, as heatwaves stress increasingly renewables-heavy power grids (note here).

Passable economics. We estimate payback periods are likely around 8-years, with 10% IRRs at a $50/ton CO2 price. Notes, numbers, cost estimates and company comments are broken out in the data-file.
