Bloom Energy’s product is proving an increasingly popular choice for data centres and in March 2012 the company launched its ‘Mission Critical Practice’, a service that aims to secure the energy supply for critical government and business IT systems.

Bloom Energy has already garnered two very substantial data centre orders in 2012: eBay is to install 6 MW of fuel.
