      That's a compound annual price reduction rate of 21%, maintained over an 8-year period! In energy technology, only solar PV comes close.https://twitter.com/BloombergNEF/status/1075410072283594753 …

      Our 2018 Battery Price Survey has found that the volume-weighted average price of a lithium-ion battery pack is $176/kWh - the price has fallen 85% in real terms since 2010 due to tech improvements resulting in higher energy density at the cathode material, cell & pack level. pic.twitter.com/BhnA6ezLrd

      However, this does not mean that batteries will be the technology of choice for longer term energy storage. While solar PV can already compete with gas-fired power, battery storage capacity still is thousands of times as expensive as gas storage.

          In UK it’s >60% gas today...WWF say that for windless days like today in UK there is no alternative to gas and they are spot on. What is the plan for windless week back up in NL from 2030?pic.twitter.com/LgkCo1y9Iv

          2030 probably still fossil gas. Later perhaps hydrogen.

          H2 made from fossil gas with CCS as promoted in UK?

          Could be a start. Gradually more green hydrogen, from renewable electricity, will become available.

          Thousands? What price It would have to reach to be competitive on it's own ? Coupled with renewables would be less

          Batteries will never be competitive for long term storage. E.g. hydrogen much more promising candidate for that.

          We need to distinguish between stored energy and stored electricity. Stored energy extracted as heat, will be cheap to get out of gas. However, getting electricity out of gas could add significantly to the cost of stored electricity. Hydrogen and fuel cells could be the way?
