Same argument as in: #2140
Enhanced Rock Weathering = spreading finely crushed silicate rocks over land, where they react with CO2 in the atmosphere and rainwater to form carbonate minerals that remain stable for thousands of years
Electricity input to capture 1 ton CO2 via ERW (to crush rocks) and costs are already included in the technology-data repository PyPSA/technology-data#256
Potential removal in every region can be estimated assuming that 20% of the arable land is used (CLC Categories non-irrigated arable land, permanently irrigated arable land, and rice fields), applying a filter for regions where the mean annual temperature >10ºC, and assuming 20 μm basalt rocks and an application rate of 150 Mt/Mha (8mm layer)
We have estimated the total removal potential of enhanced rock weathering in Europe as 43 MtCO2/a.

ERW can be modelled as a link that consumes electricity and removes CO2.
This is a description, and a PR will follow.
