NASA 2024 Space-Based Solar Power

iv Laboratory (NREL) to assess if the representative SBSP designs are competitive. We compared to NREL’s 2050 cost projections and NREL’s 2021 GHG emissions for nuclear fission, geothermal, hydroelectric, utility-scale solar photovoltaics with storage, and land wind without storage. We use 2021 emissions data because there are no projections for this data. We include land wind without storage for comparison because it has the lowest cost and lowest emission intensity of all electricity production technologies tracked by NREL.
