... Energy storage is even more expensive than thermal units' flexibility retrofits. The lithium-ion battery is the most cost-effective electrochemical storage choice, but its cost per megawatts is 1.28 million dollars, which is much higher than thermal generator flexibility retrofits .
Link between the restituted electrical power and the stored energy capacity for different storage techniques: mechanical storage in orange and chemical storage in blue—based on Limpens and Jeanmart (2018).
Comparison of storage technologies according to the global efficiency, CAPEX and LCOES—based on a Hedegaard and Meibom (2012) and Jülch (2016), b Gallo et al. (2016), c Elishav et al. (2017). With respect to these observations, the chemical storage is one of the promising options for long term storage of energy.
The storage of industrial waste heat through thermochemical energy storage (TCES) shows high potential to reduce the dependency on fossil fuels. In this paper the capital cost investment of a TCES system utilizing fluidized bed reactors and the reaction system MgO/Mg (OH) 2 is estimated and a profitability analysis is performed.
It is concluded that for the selected boundary conditions, the specific investment costs per kW stored heat are approximately 900 €/kW and that the systems should not be installed at sites where less than around 5 MW of waste heat are available.
Another contributory reason is that the average capacity factor for coal-fired power plants is assumed to be higher in the recent studies than in the SRCCS. The costs of CO 2 capture and emission avoidance (excluding CO 2 transport and storage) are 46 and 63 USD/t CO 2, respectively. These values are 6% lower than the adjusted SRCCS costs.
