WP05

Combination of renewables, heat transformation and storage for medium and high temperature heating as well as cooling

Abstract:

The aim of this work package is to develop and showcase system level solutions for heating at medium and high temperatures (approx. 90°C and above) as well as for cooling. Solutions shall propose usage of different kinds of renewable energy sources as specified in WP01 and strive for low or even negative CO2 emissions. Heat transformation and storage technologies will be incorporated to allow for technologically and socio economically optimal systems solutions. Topics such as different supply and demand profiles, peak load management, simultaneous heating and cooling, control strategies, pathways to quick market integration, etc. will be addressed. The main focus is on standalone/grid-independent settings, grids will only be taken into account as heat sources and heat sinks whenever available. Based on the assessments and learnings from the case studies, a tool will be developed proposing optimum systems solutions on demand patterns.

Objectives:

  1. Tailor combinations of which available renewable resources, heat transformation and storage technologies can be combined for heating at medium (80-200°C) and high (over 200°C) temperature levels as well as for low temperature cooling at different power levels.
  2. Showcase system solutions to gain insight into operational aspects (safety, robustness, controllability, etc.), risks (technical, financial), policy measures, legal aspects as well as business models, and how to overcome the challenges of implementation based on (mostly 3rd party funded) case studies. Deduce transformation strategies from already integrated technologies (linked with WP02).
  3. Simulation based investigation of the combination of new technologies to allow optimal matching of spatial and temporal demand at various time and length scales to avoid short term and seasonal peaks.
  4. Develop tool that helps users identify the optimal combination of renewable energy sources, storage temperatures, and heat transformation technologies for specific demand profiles (temperature, power, temporal match) based on the temperature bands developed in WP04.
  5. Initiate third party funded research and P&D projects to further develop and demonstrate the technologies (WP11) deemed most favorable in this work package, which is concentrating on systems level analysis.
