Heat exchange system to transfer waste heat from electrical load to compressed air energy storage system

A system comprising:

• a compressed air energy storage (CAES) system comprising:
• compressed air storage configured to store compressed air;
• a compressor train configured to receive electrical power from a renewable energy source (RES) to compress ambient air into the compressed air storage;
• and
• an expander train configured to decompress the compressed air from the compressed air storage to provide electrical power to a co-located data center;
• and
• a heat pump configured to transfer waste heat from the co-located data center to the expander train of the CAES system to heat the compressed air from the compressed air storage, wherein the heat pump upgrades the waste heat by collecting the waste heat at a lower temperature from the co-located data center and delivering the waste heat at a higher temperature to the expander train.

A system comprising:

• a renewable energy source (RES) configured to provide electrical power to a co-located data center and an air energy storage (AES) system comprising:
• high-potential air storage configured to store high-potential air;
• a first energy converter configured to receive electrical power from the RES to convert ambient air into high-potential air for storage in the high-potential air storage;
• and
• a second energy converter configured to convert potential energy of the high-potential air into electrical energy for the co-located data center;
• and
• a heat exchange system configured to transfer waste heat from the co-located data center to the second energy converter of the AES system to heat the high-potential air during conversion of the potential energy of the high-potential air into electrical energy, wherein the heat pump upgrades the waste heat by collecting the waste heat at a lower temperature from the co-located data center and delivering the waste heat at a higher temperature to the expander train.
