Meanwhile, to suppress the volatility of PV power generation and reduce the operation costs of the data center during peak periods of power grid, a suitable compressed air energy storage (CAES) with five stages of compression and four stages of expansion is proposed. During the day, the extra electricity from PV system is stored in CAES.
As the world shifts toward renewable energy, one major challenge remains: efficient energy storage. An EU-funded research team is exploring the use of compressed air to store excess energy collected from solar panels.
In the system they are developing, low-cost renewable electricity is used to compress air for storage during the day, while concentrated solar power feeds a thermal energy storage system. When energy demand is high, the thermal energy is used to heat the compressed air as it is released from storage to drive turbines.
The system parameters are analyzed. In order to develop the green data center driven by solar energy, a solar photovoltaic (PV) system with the combination of compressed air energy storage (CAES) is proposed to provide electricity for the data center. During the day, the excess energy produced by PV is stored by CAES.
“Compressed-air storage is not a new concept and has been demonstrated already at commercial scale,” said Zaversky. Currently, there are three compressed-air energy storage plants operating globally, in Germany, the US and China. Other sites are being explored and developed.
