Captured data center waste-heat is used as the input energy for carbon capture plant. Energy in the form of waste-heat is first captured from servers and other apparatus within the data center and optionally directed as the input to a heat-pump before being directed to the input of carbon capture plant, enabling carbon capture using a data centers waste-heat. Also disclosed are systems and apparatus for data center operators or cloud services to offer carbon negative or carbon neutral services to their customers. Cloud customers are offered options to select a carbon negative or carbon neutral service, the cloud operator storing their choice and then operating or managing carbon capture services to meet their requests.

A nuclear fuel decay heat utilization system usable for space heating in one embodiment comprises a nuclear generation plant building housing a spent fuel pool containing submerged fuel assemblies which emit decay heat that heats the pool. Plural fluidly isolated but thermally coupled heat removal systems comprising pumped flow loops operate in tandem to absorb thermal energy from the heated pool water, and transfer the thermal energy through the systems in a cascading manner form one to the next to a final external heat sink outside the plant building from which the heat is rejected to the ambient environment. A programmable controller operably regulates the intake and flowrate of water from the heat sink into the heat removal systems and monitors ambient air temperature inside to building. The flowrate is regulated to maintain a preprogrammed building setpoint air temperature by increasing fuel pool water temperature to a maximum permissible limit.

A process of transferring heat from a first relatively cold medium to a second relatively hot medium features rotating a contained amount of a compressible fluid about an axis of rotation, thus generating a radial temperature gradient in the fluid, and heating the second medium by the fluid in a section of the fluid relatively far from the axis of rotation. An apparatus for carrying out the process includes a gastight drum rotatably mounted in a frame, and a first heat exchanger mounted inside the drum relatively far from the axis of rotation of the drum.
