The first of three stages has been completed in the Nordic Energy Challenge 2022. No less than seven candidates succeeded to the second phase. The next step for these promising participants is to submit their final proposals by August 11th.
Get to know this year’s challengers, one by one, and their ideas in support of the green transition. One of the applicants is Qianwen Xu.
- Name: Qianwen Xu
- Position: Assistant Professor
- Institution: KTH Royal Institute of Technology
- Name of idea: Renewable energy-hydrogen based microgrid for sustainable Arctic communities
- Summary of idea: As the Arctic has large renewable energy resources (RESs), it is attractive to develop RES based microgrids for the electricity supply of the Arctic region. But RESs have high fluctuations, and energy storage is required for stable operation and consistent power supply. Compared with expensive battery, hydrogen storage is clean and cost-effective. Extra RES generation can be stored as hydrogen through electrolysis technology, and used later through fuel cell technology. Moreover, extra hydrogen can be exported for use in industry (e.g., steel and mining) and transportation (e.g., ship and truck). The aim of our project is to design and control a RES-hydrogen based microgrid for self-sufficient Arctic communities with zero emission.
One of the challengers will be selected winner and receive their award at the conference The Future of Maritime Fuels on October 5–6th in Nuuk, Greenland.
