The cost projections for battery storage systems and other technologies can significantly differ between the Conservative Technology Innovation Scenario and the Advanced Technology Innovation Scenario as outlined by the National Renewable Energy Laboratory (NREL) and other sources. Here’s a breakdown of these differences:
Cost Projection Differences
- Battery Storage Costs:
- Utility-Scale Battery Storage: In the Conservative Scenario, battery costs are projected to decline by 5.8% from 2030 to 2050 for utility-scale systems, with a modest CAPEX reduction of 4% between 2035 and 2050. In contrast, the Advanced Scenario assumes more aggressive cost reductions, leading to a 31% CAPEX reduction during the same period.
- Commercial Battery Storage: Similar patterns are observed for commercial battery systems. The Conservative Scenario predicts a 4% CAPEX reduction from 2035 to 2050, while the Advanced Scenario projects a 31% reduction.
- Pace of Technology Improvements:
The Advanced Scenario assumes rapid technological advancements, leading to sharper cost declines compared to the Conservative Scenario, which anticipates slower improvements. - General Trends:
Across both scenarios, battery pack costs are anticipated to reduce more rapidly than other components like balance of system (BOS) and installation costs. This trend is similar to past experiences with photovoltaic (PV) systems. - Comparison with Other Energy Technologies:
In other sectors like solar PV, NREL’s cost projections also show significant differences between scenarios. For instance, the Advanced Technology Innovation Scenario for solar PV projects sharper declines in costs through 2050 compared to the Conservative Scenario.
Implications of Cost Scenarios
- The choice between these scenarios can significantly impact planning and investment decisions in the energy sector. The Conservative Scenario is typically used for more cautious planning, while the Advanced Scenario offers a vision of what could be achieved through rapid innovation.
- The varying cost projections between scenarios highlight the importance of monitoring technological advancements and changes in market dynamics to accurately predict future costs.
In summary, the Advanced Scenario predicts faster cost reductions and more aggressive technological advancements compared to the Conservative Scenario, influencing how future energy technologies are financed and deployed.
