Cryogenic technologies use cryogens i.e. natural gas, nitrogen, helium, hydrogen, argon and oxygen as main working fluids. These cryogenic technologies and cryogens are emerging in the fields of energy storage, power generation and as eco friendly fuels.  Recently, researchers have proposed to integrate cryogenic systems with power generation systems i.e.  Nuclear power plants and wind turbines to store surplus energy during the off-peak hours and use it during the peak hours. The basic idea is to convert air or some other cryogen in liquid during the off-peak hours and expand it during the peak hours to run turbines. Whereas in shipping industry; LNG is being considered as an alternative fuel to gasoil to meet the future emissions criteria of IMO.  LNG not only reduces the vessel’s emissions but also it is cheaper than heavy fuel oils.  As every technology has some pros and cons, the efficiency of cryogenics power generation systems is low i.e. about 25% but work is being done to improve its efficiency and to find alternative applications.

This article discusses the applications, advantages and drawbacks of cryogenics technologies and fuels for energy generation and storage applications. It also focuses on the challenges which are being faced by this technology and possible ways to outcome them.

POWER-ICONE - Virtual Conference

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
