Climate tech (ie hardware and software solutions) is a bad fit for VC money outside of carbon accounting software (which adds little value) benefits.
As well this direct air capture is slightly better than CCS (read: pretty bad) but is also a red herring in terms of climate solutions that will provide a lot of value. I say this because large amounts of money will get diverted into this kind of investment that hasn't proved to be particularly successful but has an easy to understand narrative.
