Abstract

Abstract

En 中文
• Year-long demonstration confirms stable operation of an MH-based green H2 supply chain. • Maximum absorption rate of 59 NL-H2 (h·kgMH)−1 enables full charging within 2 h. • Charging rate governed by buffer tank pressure under active temperature control. • Seasonal ambient temperature has minimal impact on system performance. • Annualized power-to-power efficiency reaches 27%, comparable to alternative H2 logistics.
