AI Is Climate Tech’s Newest Hype Layer — The Commercial Problems Are Older

This is a broader industry story with no direct action for your own house, but it's worth knowing about if you follow clean energy news. The piece argues that companies in climate technology keep pairing an old, unsolved engineering problem with whatever new buzzword is popular, without actually fixing the underlying issue. It traces this pattern from blockchain (added to electricity markets around 2018) to hydrogen (added to aircraft and other industries around 2022) to today's trend of pairing AI computing with things like wave-powered ocean platforms and orbital infrastructure.

The examples given: a company called Panthalassa raised $140 million to put AI computing equipment on ocean platforms powered by wave energy, which sidesteps the need for underwater cables but doesn't solve wave energy's older problems with saltwater damage, storms, and cost. Other examples include Destinus, which shifted away from its original hydrogen-aircraft idea toward defense contracts, Aptera, a solar-powered car company that has taken reservations for two decades without shipping a production vehicle, and Gravitricity, a gravity-based energy storage company that added a hydrogen storage side project and then went into liquidation in 2025.

The bigger point: adding a trendy technology to an old problem often makes a pitch sound more fundable without making the underlying product cheaper, simpler, or more reliable. Homeowners aren't affected directly, but it's a reminder to view flashy tech announcements with some skepticism.
