Diesel powered generators have long provided support to data
centres if there are power outages or other disruptions to service
– they are expensive and rarely used. Microsoft's
announcement on Monday that hydrogen fuel cells have powered a row
of data centre servers for 48 consecutive hours has exciting
possibilities both for the data centre sector as well as
renewables.
Not only is using green hydrogen firmly in line with the
sustainability policies of many datacentre operators, but the
datacentre operators could put that hydrogen to good financial use.
Microsoft say that with the right kit installed, a data centre
could store renewable energy generated as hydrogen. That hydrogen
could in turn generate electricity for the grid and be used in
pumps for hydrogen-powered long-haul vehicles.
