This study assesses the direct and upstream socio-economic and environmental impacts of the projected deployment of CSP in China and Europe using Input-Output Analysis. The study finds that CSP has the potential to create employment and reduce carbon emissions, but efforts are needed to decrease its carbon intensity through learning.
Concentrated solar power (CSP) can be a flexible renewable resource on electric grids. Here we assess the direct and upstream socio-economic and environmental impacts of the projected deployment of CSP in China and Europe, using Input-Output Analysis. We first quantify the CSP experience curve, finding a learning rate of similar to 16%, and combine this with future projections for installed capacity from China's National Development and Reform Commission and the International Energy Agency. We find employment intensities of 4.2 and 2.3 person-year/GWh in China and Europe, respectively (higher than PV and wind). The carbon emission intensity of CSP is currently higher than alternatives but this gap may narrow through learning. Carbon intensities are estimated at 129.7 and 99.8 gCO2eq/kWh in 2020 (in China and Europe, respectively) and could drop to 40.4 and 31.1 gCO2eq/kWh by 2050 given the projected expansion. We discuss the importance of including both environ -mental and socio-economic dimensions when assessing the impact of energy technologies and provide context for the role of CSP in the energy transition.
