Hong Kong looks to underground data centers
The Hong Kong government is looking to setup data centers in underground caves, according to The Register. Plans for these facilities are progressing, says Hilary Cordell of real estate law firm Cordells, who spoke at the Datacentre Space Asia conference last week.
The Hong Kong Special Administrative Region, or SAR, is densely populated with property prices among the highest in the world, resulting in a chronic shortage of land for new data center facilities. The idea entails developing existing rock caverns that remain naturally cool.
The initial feasibility report by Hong Kong's Civil Engineering and Development Department, and engineering consultancy Arup, last year, identified two-thirds of the SAR as having "high to medium suitability" for digging rock caverns.
Some locations that were identified include Mt Davis on Hong Kong island, Lion Rock at Kowloon, Tuen Mun and Sha Tin in the New Territories, and Siu Ho Wan at Lantau. You can read the report here (pdf).
Of course, the government's hands off approach means that the responsibility will lie with the private sector. In addition, practical problems may need to be addressed, including issues like how to supply power from power stations and how to fit the centers with emergency power generators. Also, they would need to vent diesel fumes and dehumidify the area first.
