S4E15 - Is Supercritical Water Oxidation a Solution for PFAS, Energy (& More)?
with 🎙️ Kobe Nagar, CEO & Co-Founder at 374Water
💧 374Water is a cleantech company, that builds and develops Innovative physical-thermal technology (Supercritical Water Oxidation - SCWO) for resource recovery from waste and emerging contaminants elimination.
What we covered:
🥖 How Supercritical Water was discovered 200 years by a French engineer: Charles Cagniard de Latour
⚗️ How substances have a critical point, and where that one actually sits for water
🍏 How water's physical properties change when we go past its critical point
🍏 How one can leverage these changes to run supercritical water oxidation
🧮 How supercritical water oxidation (or SCWO) works, and what it can deliver in terms of pollutant removal and resource recovery
⚡ The perks of supercritical water oxidation: how fast it goes and which feedstock it works with (spoiler: all of them)
🧪 How the process can be energy positive by tapping into the chemical energy dissolved in wastewater
🍏 The perks of taking time to evaluate options when developing a new tech (and of leveraging previous experiments)
🧱 How Supercritical Water Oxidation draws on simple building blocks available everywhere
🎚️ How scale effects unlock even better energetical mass balances
📺 How SCWO developed since the 1990s (and how some developments were unnecessary complex)
🍎 How challenging it is to introduce a new technology in the Water Industry (and which technologies SCWO intends to replace)
📈 374Water’s business model and recent (external) growth
🚽 Spinning out of Duke University, Bill & Melinda Gates’ “Reinvent the Toilet” challenge, using Celsius instead of Fahrenheit, great French discoveries, being feedstock agnostic... and much more!
