数据中心（DC）正在成为一个大型工业部门，消耗约3%的全球电力供应，贡献约2%的温室气体排放总量，并且DC使用的能源量每四年翻一番。尽管华盛顿特区的能源管理系统采用了可再生能源解决方案，以减少能源消耗并限制其碳足迹，但多达一半的电力用于冷却目的，最终被浪费为热量。这里介绍了一种创新的系统，它集成了直流冷却过程与零排放的电力和冷却利用一种新的低温发动机技术。这种集成使DC能够利用热管理而不是电力的机会，通过低温储能来控制峰值温度环境和降低电价。已讨论了直流能源效率的大幅提高以及温室气体排放的减少。
Data Centres (DCs) are emerging as a large industrial sector, consuming about three percent of the global electricity supply, contributing for about two percent of total greenhouse gas emissions and the amount of energy used by DCs is doubling every four years. Despite the innovations in energy management system in DC that incorporate renewable energy solutions to reduce energy consumption and cap their carbon footprint, as much as half of electricity is used for cooling purposes and is ultimately wasted as heat. An innovative system is presented here which integrates a DC cooling process with a zero-emissions power and cooling utilising a novel cryogenic engine technology. The integration enables DCs to take advantage of opportunities for thermal management, rather than electrical power, to control peak temperature environments and electricity price mitigation through cryogenic energy storage. Substantial improvement in DC energy efficiency together with reduction in greenhouse gas emission has been discussed.
