This project report presents the main features of the three Key Enabling Technologies that are being developed within HYPERGRYD. The technologies under investigation are Modular Heat Pump with short-term PCM storage, a Sorption Thermal Energy Storage, and a Reversible micro-CHP with steam engine and steam buffer. The report delves into the main specifications and technical drawings of each technology, demonstrating the current advancement level of the development within HYPERGRYD project. The Modular Heat Pump with short-term PCM Storage technology offers a scalable and efficient solution for heating and cooling applications. It employs phase change materials (PCM) to store thermal energy for DHW, releasing it during peak demand, thus optimizing energy consumption. The Sorption Thermal Energy Storage introduces a novel approach to energy storage through reversible physical-chemical reactions. This closed-loop system utilizes composite materials to store and release energy in the form of heat, demonstrating excellent energy density and prolonged storage durations for both heating and cooling. The Reversible micro-CHP with steam engine and steam buffer combines heat and power generation, achieving enhanced system efficiency through waste heat recovery. By utilizing a reciprocating piston engine, it simultaneously produces electricity and captures waste. This recovered heat finds applications in heating, or industrial processes, making the cogeneration unit a versatile and fuelflexible choice. The report is a document intended for HYPERGRYD consortium members, in particular to the pilot owners where the Enabling Technologies will be installed and the owners of tools from HYPERGRYD platform, who can use the provided drawings and specifications as inputs for the tools/platform.
