Top Challenges

  • 1Most sensors get damaged in high-moisture conditions, requiring constant recalibration
  • 2High heat in the electrolyzer module requires gases to be cooled before detection
  • 3Most sensors today fail when exposed to high levels of hydrogen
  • 4Other sensors available cannot endure the harsh conditions inside electrolyzers
  • 5Lack of on-chip intelligence makes it difficult to execute shutdown protocols and alarming logic
  • 6Low availability of sensors due to supply chain bottlenecks
