Abstract

In this paper, we propose a system of bidirectional power routing for inter-house multi-energy management systems that utilize electricity and hydrogen as energy carriers. The key is to share private facilities such as photovoltaic panels and batteries among a group of houses along with a common hydrogen system. A power router of line switching type is introduced as a physical interface to realize the sharing economy between households. The proposed system offers a unique measure to address the urgent challenges of today's multi-energy system, namely increasing the renewables' self-consumption, enhancing the energy system's resilience, and providing traceability of hydrogen in terms of renewability certification. We also present an experimental demonstration under a simplified scenario using prototype hardware.
