DATA CENTRES

Some of the world’s largest data centres can each contain many tens of thousands of IT devices and require more than 100 megawatts (MW) of power capacity—enough to power around 80,000 U.S. households (U.S. DOE 2020). 40% of the power use from a typical onshore data centre is used to cool equipment.

Data Centres

The substantial electricity use of data centres also gives rise to concerns over carbon dioxide (CO²) emissions from processing and storage to data communication. Our expertise can help owners and operators of data centres and data hubs to transition to wave power for their cooling systems as well as a facility’s complete power supply. WaveRoller® is an ideal technology to be combined with both onshore and offshore data centre energy needs as filtered seawater can be used to replace inefficient air cooling and supply data centres with green electricity to reduce emissions and substantially reduce operational costs.

ADVANTAGES

WaveRoller supplied data centres located onshore or on the seabed, have a number of advantages, both in terms of efficiency and security.

EFFICIENCY

Efficient cooling of data centres is an important method to reduce energy consumption. For new data centres in cool climates Climate Neutral Data Centre Pact has targeted 0.3 kWh of energy used for cooling for each 1 kWh used for IT equipment. In warm climates that increases to 0.4 kWh. Sea water surrounding a subsea data centre provides a natural cooling medium. In addition, the subsea location provides additional security by preventing access.

YEAR ROUND

WaveRoller power profile complements solar and wind, thus enabling security of supply. For example, in California during the winter months solar and wind produce less energy, whereas wave energy increases in the winter, thus enabling data centres to efficiently source renewable energy year-round.
