Can fluctuating PV power output be stored as MCH?

Complete 1 day profiles were applied for MCH production, and MCH with almost the same purity as the target was obtained, indicating that fluctuating PV power output can be stored as MCH without hydrogen buffer tanks and compressors. The results show a promising possibility to achieve simple and low-cost systems for energy storage.

How does MCH work?

In MCH’s case, the organic chemical toluene is used as the base commodity which is then reacted with hydrogen to produce MCH. After the initial hydrogenation step, the energy carriers are transported by truck to an integrated facility “near a region where demand has outstripped the load capacity of transmission lines.”

Can PV power output be stored as MCH without hydrogen buffer tanks?

Of the hydrogen produced by the electrolyzer, 73% was used by the MCH production reaction. Complete 1 day profiles were applied for MCH production, and MCH with almost the same purity as the target was obtained, indicating that fluctuating PV power output can be stored as MCH without hydrogen buffer tanks and compressors.

How much hydrogen is used to produce MCH with 93% purity?

In this investigation, hydrogen utilization was approximately 70% for producing MCH with 93% purity using the PV fluctuating powers. The MCH production system using fluctuating electricity was investigated to realize a simple and low-cost energy storage system.

What is electrochemical energy storage system?

chemical energy in charging process. through the external circuit. The system converts the stored chemical energy into electric energy in discharging process. Fig1. Schematic illustration of typical electrochemical energy storage system A simple example of energy storage system is capacitor.

What are ammonia & MCH?

Ammonia and MCH are two of the three hydrogen vectors that were studied by the Energy Carriers initiative within the Government of Japan’s Strategic Innovation Promotion Program between 2014 and the first quarter of 2019. (Liquid hydrogen is the third.)
