Free QuoteTraditional ways to improve storage technologies are to reduce their costs; however, the cheapest energy storage is not always the most valuable in energy systems. Modern techno-economical evaluation methods try to address the cost and value situation but do not judge the competitiveness of multiple technologies simultaneously.
The ratio of charging/discharging unit power and storage capacity is important. PSH and CAES are low-cost technologies for short-term energy storage. PtG technologies will be more cost efficient for long-term energy storage. LCOS for battery technologies can reach about 20 €ct/kWh in the future.
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
PSH and CAES are low-cost technologies for short-term energy storage. PtG technologies will be more cost efficient for long-term energy storage. LCOS for battery technologies can reach about 20 €ct/kWh in the future. This paper presents a detailed analysis of the levelized cost of storage (LCOS) for different electricity storage technologies.
Power to Gas technologies, once established on the market, may also provide long-term electricity storage at even lower LCOS. Pumped-Storage Hydroelectricity is also the cheapest technology for short-term storage systems. Battery systems at the moment still have high costs but are expected to have a sharp price decrease in the near future.
The energy weighted cost of a storage system (€/kWh) is minimised, without any electricity price signal, by a cost optimisation model that simultaneously maximises the round-trip efficiency of the storage.
