Environment and Environmental Credits

The use of electricity storage can reduce overall air emissions for fossil fuel plants, the amount depending on the generation plants and fuels used.  For example, by arbitrage because cleaner fuels and more efficient generation plants are typically available off-peak, by load following because changing power output in any way requires excess fuel (efficiency is less during these periods).  The increase in the use of renewables can provide an environmental credit that can be used either directly by the owner of the storage device or can be traded/exchanged for other benefits with users who need, e.g., carbon credits.
