P2H-Pot - Potentials, economic feasibility and system solutions for Power-to-Heat

P2H-Pot will identify economically feasible potentials for Power-to-Heat (P2H) in urban regions. The suitability of different technical system configurations are investigated using thermodynamic simulation and considering experiences from Scandinavian cases. The assessment of short, medium and long term relevance and economic feasibility of P2H is accomplished by simulating model-based scenarios up to 2050 of the Austrian and German electricity and heat market. In cooperation with a district heating company three case studies will be carried out.

Short Description

Status

ongoing

Summary

Starting point / motivation

The need for more flexibility of the electricity demand increases with the growing share of volatile renewable energy. Results from recent projects and international studies show that the use of electricity in the heating sector combined with heat storage (Power-to-Heat) shows the most promising economic potentials to achieve this high flexibility.

Contents and goals

The objective of this research project is to identify the technical and economical potentials of innovative P2H system solutions in urban regions for the years 2020/2030/2050 and to determine the required legal, fiscal and regulatory framework conditions.

Methods

For this purpose, we will start with detailed thermodynamical simulations of innovative P2H solutions and investigate potentials, regional and temporal availability of various heat sources for Austrian district heating grids, the potentials and barriers for efficient combined heat and cooling plants and the impact of a targeted management of initial flow and return flow temperature in district heating grids.

A basic precondition for analyzing the economics of P2H solutions is to consider the whole relevant electricity market (for the case of the project P2H-Pot: Germany and Austria), rather than single urban regions, because the overall electricity market determines the volatility of electricity prices and thus the operation periods of P2H, the optimum system design of P2H and the economic framework conditions. This analysis will be carried out with the model HiREPS, which is an optimization model of the German and Austrian electricity and heating sector.

For all investigations we take into account a detailed assessment of possible future regional distribution of heating and cooling energy demand and of the installed heating and hot water systems, based on the well proven and validated model Invert/EE-Lab. The practical relevance of the analyses will be shown in three case studies of Austrian district heating grids.

Expected results

The core results of the project P2H-Pot are:

  • system configurations for the technical implementation of P2H including an assessment of the energetic and exergetic efficiency,
  • economic potentials and the relevance of power-to-heat in various framework conditions of the central European electricity and heating sector and for the development of the heating and cooling demand,
  • a concrete assessment of the technical and economical feasibility of P2H for three case studies,
  • identification of barriers against P2H and approaches for overcoming these barriers and
  • high impact of the project through comprehensive and target group oriented dissemination activities.

The high-level consortium guarantees a highly qualitative and professional study. The Danish project partner ENERGIANALYSE.DK will provide practical experiences from Scandinavia.

The involvement of Energie AG, the review Workshop, the international advisory board and the intensive stakeholder dialogue make sure that the assumptions correspond to practical experiences and that the investigated research questions are highly relevant for the companies in the energy field.

Comprehensive dissemination activities guarantee a target group oriented dissemination of project results and a high impact of the project beyond the project duration.
