• Analyst Opinion
  • Shambhu Nath Jha, Principal Consultant at Fact.MR, says 'The water electrolysis machine market is at the center of the global hydrogen economy transition, with government mandates and climate commitments creating demand visibility that extends decades forward. The market will grow nearly fivefold by 2036, making it one of the fastest-expanding industrial equipment categories globally. The critical competitive variable is manufacturing cost reduction speed. Manufacturers that achieve USD 200 to USD 300 per kilowatt stack costs first will capture disproportionate market share as project economics become the primary procurement criterion. Alkaline technology leads on cost and scale, PEM leads on flexibility and footprint, and SOEC offers the efficiency frontier. The market will support all three technologies, but manufacturing scale will determine competitive positioning.'
