Current developments in heat pumps, supported by innovative business models, are driving several industry sectors to take a proactive role in future district heating and cooling networks in cities. For instance, supermarkets and data centers have been assessing the reuse of waste heat as an extra source for the district heating network, which would offset the additional investment in heat pumps. This innovative business model requires complete deregulation of the district heating market to allow industrial heat producers to provide waste heat as an additional source in the district heating network. This work proposes the application of innovative market designs for district heating networks, inspired by new practices seen in the electricity sector. More precisely, pool and market designs are addressed, comparing centralized and decentralized market proposals. An illustrative case of a Nordic district heating network is used to assess the performance of each market design, as well as the potential revenue that different heat producers can obtain by participating in the market. An important conclusion of this work is that the proposed market designs are in line with the new trends, encouraging the inclusion of new excess heat recovery players in district heating networks.
The paper performs an assessment of the decarbonisation potential in utilizing industrial excess heat to meet the baseload heating requirements of a district heating network in Portugal. The excess heat source considered was a municipal waste-to-energy plant located 5km from a district heating and cooling network. It performed an economical comparison between two integration procedures: (i) extending the existing pipeline to the excess heat source; and (ii) using a continuous supply of portable thermal storage modules. For the excess heat characterization and tecno-economic assessment, the EMB3RS platform was used. The analysis demonstrated the pipeline alternative more economically feasible (with a levelized cost of heat of 17,25 €/MWh), meeting the baseload consumption with a decarbonisation reduction potential of 30 %. The higher levelized cost of heat of the portable thermal storage solution is mainly due to the high daily replacement cost for the thermal stores.

District heating systems become more distributed with the integration of prosumers, including excess heat producers and active consumers. This calls for suitable heat market mechanisms that optimally integrate these actors, while minimizing and allocating operational costs. We argue for the inclusion of network constraints to ensure network feasibility and incentivize loss reductions. We propose a network-aware heat market as a Quadratic Program (QP), which determines the optimal dispatch and a set of nodal marginal prices. While heat network dynamics are generally represented by non-convex constraints, we convexify this formulation by fixing temperature variables and neglecting pumping power. The resulting variable flow heating network model leaves the sign and size of the nodal heat injections flexible, which is important for the integration of prosumers. The market is based on peer-to-peer trades to which we add explicit loss terms. This allows us to trace network losses back to the producer and consumer of these losses. Through a dual analysis we reveal loss components of nodal prices, as well as relations between nodal prices and between seller and buyer prices. A case study illustrates the advantages of the network-aware market by comparison to our proposed loss-agnostic benchmark. We show that the network-aware market mechanism effectively promotes local heat consumption and thereby reduces losses and total cost. We conclude that the proposed loss-aware market mechanism can help reduce operating costs in district heating networks while integrating prosumers.

This paper assesses the decarbonisation potential of utilizing industrial excess heat to meet the baseload heating requirements of a district heating network (DHN) located in the Portuguese capital. It performs an economical comparison between two integration procedures: (i) extending the pipeline to the excess heat source; and (ii) using a continuous string of portable thermal storage modules. In this scope, this work assesses the integration of the excess heat from a municipal waste-to-energy plant located 5km from a district heating and cooling network and the decarbonisation potential achieved by meeting the baseload heating requirements of the DHN. For the characterization of excess heat and economic analysis, the EMB3RS platform was used. The analysis showed that laying out a new pipe route was more economically feasible (with a levelized cost of heat of 17,25€/MWh), meeting the baseload consumption with a decarbonisation reduction potential of 30%. The higher levelized cost of heat (LCOH) of the portable thermal storage solution is mainly due to the high daily replacement cost for the thermal stores.
The integration of prosumers (consumers who can both consume and produce energy) in a current district heating network (DHN) brings new challenges to the market and DHN operation, since they can change the thermal flow in the DHN and increase competition in the district heating market. In this scope, this work proposes the implementation of a coordination methodology based on a peer-to-peer (P2P) market to enable bilateral energy trades between producers, prosumers and consumers, coupled with the DHN operation. A Nordic DHN containing prosumers is used to test and validate the proposed methodology. The results point out that the coordination methodology is able to provide compromise solutions between the market negotiation and the DHN operation. An important conclusion is that the coordination methodology encourages prosumer integration in DHN, increasing market competition that may pull down the energy costs for consumers while avoiding DHN's operating and management burdens.

Developing an excess Heat/Cold (re)use matching platform for industry and end users.
16 companies and institutes from across Europe have joined forces as part of the EU-funded project EMB3Rs to add value to waste heat and help make better use of renewable energy sources. A novel tool, to be developed by August 2022, will allow energy-intensive industries and other excess heat and cold sources to explore ways of reusing their excess thermal energy. This will improve their energy performance and contribute to a healthier future for everyone.
Users, like industries that produce waste heat, will provide the essential parameters, such as their location and the available excess thermal energy. The EMB3Rs platform will then autonomously and intuitively assess the feasibility of new business scenarios and identify the technical solutions. End users such as energy communities will be able to determine the costs and benefits of industrial excess heat and cold utilisation routes and define the requirements for implementing the most promising solutions. Matching excess heat providers with end-users will enable win-win partnerships and reduce CO2 emissions.
Seven case-studies will deliver data to create and validate the platform including the re-use of excess heat from a cement producer and a metal casting company, an industrial park and local supermarkets in district heating networks. The project kicked off in September 2019 and will last for three years.
The four key messages of EMB3Rs
–             Easy matching between sources and sinks for residual heat and cold (HC)
–             Exploring of economically viable business cases for the use of excess HC
–             Optimisation of techno-economic parameters of proposed solutions
–             Lower energy costs, improved competitiveness and reduced environmental impacts
EMB3Rs stands for “User-driven Energy-Matching & Business Prospection Tool for Industrial Excess Heat/Cold Reduction, Recovery and Redistribution.
