Xinao Power and Meiyuan Power Jointly Break Through, Magnesium-Based Hydrogen Storage Power Generation System Empowers Hydrogen Energy Industrialisation

Recently, Xin'ao Power and Shanghai Meiyuan Power Technology Co., Ltd. jointly completed a technological breakthrough, successfully achieving the joint commissioning of magnesium-based solid-state hydrogen storage and a micro gas turbine. A new-type energy system integrating safety, efficiency, and flexibility has been officially unveiled, addressing key technical challenges for the large-scale application of hydrogen energy.

It is reported that the system uses high-performance magnesium-based alloy as the hydrogen storage medium, achieving high-density hydrogen storage under low-pressure conditions, with a hydrogen release rate of 6.5 kg/h, ensuring continuous and stable energy supply. Meanwhile, an innovative design introduces the gas turbine's 600°C high-temperature exhaust gas into the hydrogen storage system, establishing a synergistic "hydrogen-heat-electricity" cycle, with the comprehensive energy utilization rate exceeding 80%, and supporting blended combustion of hydrogen and natural gas as well as dual-fuel direct injection modes. Key test data show that the system stably outputs 135 kW of electricity, has a hydrogen storage capacity of 100 kg, achieves a hydrogen blending ratio of 50%, and operates smoothly.

Currently, the system has demonstrated application potential in distributed energy, enterprise green transformation, ESS peak shaving, and emergency backup power supply, providing a practical and innovative solution for the industrialisation of hydrogen energy and accelerating the industry's shift toward low-carbon and high-efficiency development.
