The German Federal Office of Economics and Export Control (BAFA) funds feasibility studies with up to 60 percent of the eligible expenses (funding module I) and a maximum funding amount of 600,000 euros.
A fourth-generation heating network is an innovative heating network with a predominant share of renewable energies. The heat networks distribute heat either as usable heat of about 60 °C (with a low return temperature of about 30 °C) or as so-called anergy of about 20 °C to 0 °C as a heat source for heat pumps.
As part of the feasibility study, we are developing and comparing various innovative concepts for grid-based heat supply technically and economically. At least 50% of the heat demand shall be provided by renewable energies, with a maximum of 25% biomass. The energy supply should be designed efficiently and contain forward-looking components, such as intelligent use of sector coupling (heat, cold, electricity) and a monitoring concept.
Our feasibility studies offer you planning expertise with utmost ecological and economical benefit and application-specific elaborations, e.g. on:
- Possible innovations in the heat network system
- Target temperature level of the network flow for all variants to be investigated
- Identification of heat sinks (connections)
- Calculation of the load curve
- Dimensioning of heat sources
- Use of heat storage facilities
- Climate compatibility of the energy sources used
- Legal permissibility
- Sector coupling and electricity market efficiency
- Efficient design of the house transfer stations
- Concept of online monitoring
On this topic, also take a look at our web seminar on "Introduction to the planning of anergy networks". Dr.-Ing. Bernd Vogl discusses cold local heating networks together with Dipl.-Ing. Hubert Graf from GRATEC GmbH and Christian Fritz from GF Piping Systems GmbH. Here you can watch the recording from 03 February 2022 - it is in German only without subtitels: https://lnkd.in/dcEbGsq5
