The battery may be the core of low power.
Carbon energy systems with high share of intermittent renewable energy.
However, it is still believed that investment in batteries is very attractive and therefore policies are needed to support deployment.
Here we show how to potentially reduce the cost of battery deployment by introducing an aspect that has been overlooked in policy debate and basic analysis: one battery can serve multiple applications.
As a result, the battery can not only mine different value streams, but also combine different risk exposures.
To address this gap, we have developed a technology
Economic model and apply it to lithium-
Ion batteries for multiple fixed applications in Germany.
Our results suggest that even if not now, the battery may be attractive to investors.
Remove the market barriers that hinder the application mix.
The current policy debate should therefore be refocused in order to include the removal of these obstacles.
