Problem: the need for connectivity and bigger servers is increasing, but they are hugely energy intensive.
Solution: Give the produced heat a purpose, to create energy savings somewhere else and prevent energy wastage.
- Data centers require a large number of fans and cold water to keep them cool. The fans are really loud, and the heat produced is usually wasted.
- Stockhold Data Parks runs in partnership with the city’s government, Fortum Värme (heating and cooling agency) to try to optimize the use of this heat.
- Cold water feeds through pipes to the data centre, where it is heating through the data centre’s cooling process, and then runs back to Fortum’s plants where it is used for heating.
- Stockholm Data Parks expects to generate enough heat to warm 2,500 residential apartments by 2018, but the long term goal is to meet 10% of the entire heating need of Stockholm by 2035.
- Possible commercial customers (shopping malls etc)
- Residential buildings – 10 MW of energy is needed to heat 20,000 modern residential apartments, whereas an average Facebook data centre uses 120 MW.
- Companies with data centers
- City governments and local utility providers
- List and contact stakeholders (listed above)
- Model partnerships between heat producers and consumers which are geographically efficient.
- Value the cost incentive – will it save money overall with the new infrastructure investment?
Comment on CyberRain:
This technology could have the potential to be expanded to cities that make use of rainwater for other uses, or monitor city-wide water management during unpredictable rainfall seasons and drought conditions. It could also be incorporated into water payment systems to create incentives for water savings on irrigation.
