Last week’s poll: which approach to battery storage do you favour?

Last week’s poll attracted a strong response of 644 votes, but the results require a little explanation.

The leading single option for battery storage mode was to locate batteries in a decentralised fashion, with units in homes, resulting in a more resilient system. This attracted 15 per cent of total votes, with centralised storage using very large capacity batteries attracting 7 per cent.

However, by far the most popular option, with a clear majority of 57 per cent of votes, was to opt for some mixture of both options. Meanwhile, 18 per cent of respondents believe that lithium-ion storage should not be the target for investment, and three per cent declined to pick an option.

The feedback section was as lively as ever, attracting 34 comments. Richard Masters commented that he didn’t favour any bulk battery storage system: “they’re toxic, unsustainable and very short lived.” His favoured option was for a low rpm motor/generator flywheel system.
