Cooling for the Future
Heat pumps – the mere term implies that the technology is used for heating. And heating has been in focus for the Heat Pumping Technologies TCP over the years. But this is slowly changing. As ever more people can afford installations for cooling, there is a rising need for novel cooling technologies world-wide, preferably without refrigerants with high climate impact. Therefore, the topic for this issue of HPT Magazine is "Cooling for the Future". We hope that this will be of interest to even more than the present HPT member countries!

Below is a list of articles included in the Magazine. The articles in bold can also be found further down, in versions shortened by the HPC.
  • Foreword: Cooling and refrigeration: what lies in the future? By  Van D. Baxter
  • Column: Why we should take a closer look at Eastern Europe, by Thomas Fleckl
  • Heat Pumping Technologies News
  • News in focus: Positive energy districts in Europe – a definition is on its way
  • Annexes in HPT TCP: 43, 47, 48, 49, 52, 53, 54, 55
  • Strategic Outlook for the Netherlands: Climate Agreement, by Marion Bakker

Strategic Outlook for the Netherlands: Climate Agreement
Historically, the Netherlands rely heavily on natural gas for heating of buildings. But current environmental goals are challenging that situation. According to the National Climate Agreement, the emission of greenhouse gases should be reduced by 49% until the year 2030, compared to the emission levels in 1990.

The way forward on how to fulfil this Agreement has been carved out through a joint work between the government, businesses and NGOs. In total, more than a hundred stakeholders have co-operated on proposals on how to reach the target. The work has been divided between five sector platforms, focusing on Built environment, Mobility, Industry, Electricity, and Agriculture and land use, respectively. This article focuses on the results regarding Built environment.

Electrochemical Membrane Technologies for use in Energy Systems
To a layman, a heat pump seems to magically draw heat from thin air. But behind that perceived magic is a construction with mechanical compression of fluids, supplying the work needed for useful heating and cooling. This article presents an alternative to the mechanical compression, moving away from the use of moving parts. Instead, the compression is done through a chemical process. The phenomenon, called electrochemical compression (EC), has the potential to be used in applications such as heat pumps, energy storage and dehumidification.

Elastocaloric Cooling
Current heat pumping technologies use a vapor compression cycle with a liquid refrigerant. In recent years there has been an increased interest in systems using a solid refrigerant instead, eliminating the negative environmental impact of today’s refrigerants. It is common that they either deplete the ozone layer or contribute to the global warming. This occurs when the refrigerant leaks, a phenomenon that you won’t have with a solid refrigerant. A group of interesting solid-state materials for this purpose are so-called caloric materials.

Development of an Underground Thermal Battery for Enabling Ground Source Heat Pump Applications and Shaping Electric Demand of Buildings
Ground source heat pumping is an energy efficient technology for space heating, space cooling, and water heating. But a large-scale market introduction, at least in the United States, is hindered by high installation costs of the connected heat exchanger. And the cost-reduction efforts tested so far have restricted potential due to the sizing of the borehole.

Recently, a new type of ground heat exchanger was developed, which could change this. It is an underground thermal battery, showing promising results in lab tests. According to them, this type of heat exchanger could achieve the same performance as the conventional type, to a cost that is lowered with 39% according to preliminary cost analyses.

Industrial Heat Pumps in the Danish Energy System – Current Situation, Potentials and Outlook
Denmark has a target to meet 55% of its energy demand with renewable production until 2030. While the electricity was already 64% renewable in 2017, the challenge lies within the heating sector. This creates perfect conditions for wide implementation of heat pumps. Two areas of interest for implementation are district heating systems and industrial applications. For district heating, this is already demonstrated through several successful installations. The focus there now lies on upscaling and operation as well as on exploiting further benefits. The development regarding industrial installations is not as strong. There the focus lies on simplifying the optimal integration of heat pumps and enabling higher supply temperatures.
