Hydrogen Production Industry Solution

Industry Pain Points

  • High Energy Consumption and Costs: Traditional alkaline electrolysis for hydrogen production has an energy consumption of ≥4.5 kWh/Nm³ H₂, with electricity costs accounting for over 70% of the total hydrogen production cost. PEM electrolyzers rely on precious metal catalysts (platinum, iridium), resulting in an equipment investment of up to 12,000 RMB/kW.
  • Poor Adaptability to Fluctuating Power Sources: When the power supply from renewable energy (wind/solar) fluctuates by ±30%, the electrolyzer efficiency drops by 40% and its service life shortens by 50%.
  • Insufficient Hydrogen Purity: The purity of hydrogen from alkaline electrolysis ranges from 99.5% to 99.9%, containing trace KOH mist (≤1ppm), which causes poisoning of fuel cell catalysts.
  • Lack of Green Hydrogen Certification: Existing systems cannot track carbon footprints in real time, making it difficult to meet international green hydrogen standards (e.g., RFNBO).

SYSTEM OVERVIEW

Yipu Hydrogen Production System achieves the following through a technology closed-loop of “non-precious metal electrolysis – wide-frequency adaptation – green hydrogen certification”:

  • Cost Breakthrough: The levelized cost of green hydrogen (LCOH) is reduced to 18 RMB/kg (compared to over 25 RMB for traditional systems).
  • Reliable Operation: Electrode service life of 80,000 hours, adapting to extreme wind and solar power fluctuations.
  • Asset Appreciation: Internationally certified green hydrogen obtains a carbon premium, increasing the project IRR by 3-5%.

Technical Principles

Yipu Three-Stage Low-Carbon Decarbonization Process

  1. Pre-Treatment Enhancement (Stage 1): A cyclonic dust removal-chemical scrubbing tower removes 99% of dust, SOx, and NOx (to <1ppm) to protect subsequent systems.
  2. Efficient Absorption (Stage 2): New low-energy solvent (NE-7):
    • Absorption capacity reaches 2.5mol CO₂/mol amine (only 0.5 for MEA)
    • Regeneration temperature is reduced to 90℃ (120℃ for traditional methods), cutting energy consumption by 40%
  3. Green Regeneration (Stage 3): Solar heat collection + waste heat steam drive the regeneration tower, saving 100% more energy than electric heating.
  4. Intelligent Optimization: AI algorithms dynamically adjust solvent circulation volume to adapt to 5-30% CO₂ concentration fluctuations.
