The new process that we, at Hydropunk, are building rethinks the caustic production process and optimizes for direct DC input from solar eliminating power systems performing AC-to-DC conversion.
We have a TRL 6 prototype derisking our process and hardware costs. We are on track to getting to <$400/kW load CAPEX.
If you want to chat about how we do it (our secret sauce), send an email to rakshith@hydropunkindustries.com
