The final list of signatories for pledges on expanding energy storage and grid capacity taken at the UN Cop 29 climate summit, was released today, almost four weeks after the commitment was first finalised, with 58 countries out of almost 200 Cop parties taking part.
Signatories commit to a collective goal of increasing electricity storage capacity to 1500GW by 2030, a sixfold increase from 2022. Another pledge is to add or refurbish 25mn km of grid infrastructure by 2030, and recognise the need for an additional 65mn km by 2040. Lack of firm, clean power generators to back up intermittent renewables is a major barrier to increasing renewable penetration, while distributed resources require large investments in power grids to transport electricity to consumers.
The list of 58 signatory countries includes the so-called troika of Cop host countries the UAE, Azerbaijan and Brazil. The US and all other G7 member states are present, with the exception of France. Also absent among major economies are China and Russia, while Saudi Arabia spoke in support of the pledges during Cop but does not appear on the list of signatories.
In comparison, almost 120 countries had signed a pledge to triple global renewable capacity double global energy efficiency by 2030 during the Cop 28 summit in Dubai last year.
The grids and storage pledges were one of the centrepiece announcements made by the Azeri host, following on from the calls made in Dubai on renewable capacity and energy efficiency, but also on transitioning away from fossil fuels in energy systems.
But divergences on mitigation — actions to cut greenhouse gas emissions — during the summit this year, meant that the completed pledge, as well as any other specific mentions of fuels and energy transition technologies, were not included in final outcome texts.
