Battery

Pros:

  • density

Cons:

  • price
  • degradation

Outlook: going to become cheaper

Category:Batteries

Gravity Battery

Pros:

  • price per MWh stored
  • longevity

Cons:

  • density

Types:

Outlook: cost breakthrough is expected

Long-term storage (better scalability)

Power-to-gas

PEM - older technology, expensive

Alcaline - cheaper, more durable, more pure output gases (https://en.wikipedia.org/wiki/Alkaline_water_electrolysis)

LCOE: ?

good price, problem with longevity (not enought cycles)

Compressed Gas
