Meanwhile, NDRC and NEA published a roadmap for the country’s energy storage sector for the 14th FYP period. The policy sets out targets for different energy storage sectors in terms of technological breakthroughs and price reductions.
Energy Iceberg’s Note: however, it is critical to notice that the policy did not confirm the total installation target for new-type energy storage, which was proposed by the regulator in the previous (feedback-inviting version.) The drop in the installation target–previously suggested to be 10X of the current size–may indicate a less positive view of the regulator on the commercialization of the sector in the near run.
The policy committed to:
- Promote larger-scale use of non-hydro energy storage technologies at lower costs in order to back up the world’s biggest fleet of wind and solar power plants.
- Reduce the cost of electrochemical energy storage systems by 30% by 2025.
- Achieve technical modification applications on conventional power sources, such as extraction steam energy storage for coal-fired power and nuclear power units
Achieve large-scale demonstrations of 100-MW compressed air energy storage
Advance MW level flywheel energy storage and other mechanical energy storage technologies.
Seek breakthroughs in long-duration storage technologies such as compressed air, hydrogen, and thermal energy, and aim for self-reliance in key fields.
The plan calls for the collective development of various new energy storage technologies, including sodium-ion batteries, new lithium-ion batteries, lead-carbon batteries, flow batteries, compressed air, hydrogen (ammonia), and thermal (cold) energy storage technologies.
In particular, the plan calls for developing demo application projects of various new energy storage technologies, including:
- systematic applications of 100-MW level advanced compressed air
- demon application of Na-ion battery and solid-state lithium-ion battery
- High-safety and large-scale development of lithium-ion batteries
- Industrial application of vanadium flow battery, iron-chromium flow battery, zinc-bromine flow batteries.
- Large-scale application of flywheel energy storage technology
- Pilot of stream-extraction in coal-fired and nuclear power
- Demonstration application of renewable power-to-gas hydrogen (ammonia) and hydrogen-to-electricity solutions
- Hybrid energy storage technology
Energy Iceberg’s Note: based on the sequence of the technology mentioned in the policy and the phrasing, the regulator emphasized the commercialization and large-scale development of lithium-ion BESS, compressed air, and flywheel storage in the coming years. Hydrogen-ammonia remains at a demonstration phase
