VIRTUAL MEETING | Cryogenic Energy Storage for a Net Zero Carbon Future
LOCATION
SPEAKER| Prof Yulong Ding, University of Birmingham
BIOGRAPHY| Yulong Ding is Professor of Chemical Engineering at the University of Birmingham and Director of the Birmingham Centre for Energy Storage. He joined Birmingham in 2013 and before that he was Professor and Director of the Institute of Particle Science and Engineering at the University of Leeds. Previous roles included time at Imperial College London and the University of Science and Technology at Beijing. Yulong was the founding director of the joint Institute for Energy Storage between the University of Leeds and the Institute of Process Engineering of the Chinese Academy of Sciences.
The global impacts of the changing climate have become increasingly visible in recent years. To address such a colossal challenge, the UK took the lead in the world to adopt a highly ambitious target in 2019 to reduce greenhouse gas emissions to net-zero by 2050. This target, together with legislated carbon budgets, imply the needs for more radical emissions cuts across the economy and significantly greater renewable penetration into our energy systems.
This talk started with a short overview of the world final energy consumption, together with recent renewable penetration and energy efficiency data, aimed to illustrate true challenges from a decarbonisation perspective. Brief remarks were made on the most popular emerging energy technologies, including electrification of transport, hydrogen economy, and carbon capture and storage, aimed to highlight the urgent needs for substantial energy efficiency enhancement of these technologies through a multi-vector-based whole system approach.
The majority part of the talk was on cryogenic energy storage (CES). The CES technology uses a cryogen (e.g. liquid air, nitrogen, or carbon dioxide) as a medium and also a working fluid for energy storage and release processes. I took liquid air as an example -
• During off-peak hours when electricity is cheap and demand is low, liquid air is produced in an air liquefaction plant and stored in a cryogenic tank at around -190Co and close to the atmospheric pressure.
• During peak hours, the stored liquid air is heated up by the environmental heat first, and then superheated by waste heat recovered from the air liquefaction process as well as other heat sources if available. The boiling of the liquid air forms a high-pressure gas which drives an expansion device to produce shaft power.
This was a 45-minute talk followed by a 15 minute Q&A. The meeting opened from 5:50pm for attendees to join and the event started promptly at 6:00pm.
