BR1: Hydrogen4GreenIT

This dissertation project creates the methodological basis for modular, hydrogen-powered, and container-based data centres (hydrogen for green IT).

For the overall system of a small modular data centre, consisting of computer, hydrogen generator, and hydrogen tank, a simulation is created that plans a throughput-optimised, load-balanced computing operation in order to be able to compensate for the fluctuating availability of natural energy through energy storage in conjunction with suitable scheduling and configuration strategies. In particular, the question of how long computing jobs can be processed with specific configurations of the hardware and energy infrastructure, how the load must be distributed among the processors for this purpose, and how the overall throughput of the data centre can be increased is investigated. Here, methods of energy-conscious configuration, which have already been developed at the applicant's chair for classic software and hardware, are extended to energy storage and scheduling strategies. For this purpose, the already existing energy consumption contracts for software and hardware components must be extended to hydrogen generators and hydrogen tanks, which requires the modelling of continuous energy flows in the overall system. As a result of the dissertation, the world's first energy contract system for computer systems embedded in their energy environment will be created and evaluated (through comparative simulation).
