Redesigning District Heating Networks for Cooling Capacity

In the city of Helsingborg in Sweden, the municipal energy company Öresundskraft supplies District Cooling to a variety of customers in the downtown area. Customers include large users such as a pharmaceutical production facility and a major hospital together with an array of offices and other commercial buildings. The system that has been in operation since 1999 has now been reengineered to allow for an expansion to 30 MW (thermal) cooling capacity and to significantly improve energy efficiency and environmental performance.

A master plan for creating a hydrogen valley in Spain

In 2003, a hydrogen strategy was developed by the Government of Aragon. Its main objective is the development of new hydrogen technologies integrated with renewable energies and the promotion of Aragon’s incorporation to economic activities related to the use of hydrogen as an energy vector. To that end, the organisation, management, and execution of a wide range of actions in order to generate, store and transport hydrogen for its use in fuel cells, in transport applications or for the generation of distributed energy is carried out. The Government of Aragon aims to encourage research, technological development, cogeneration and industrial adaptation, contributing to industrial modernisation and the improvement of competitiveness. The implantation of projects based on sustainable energies that provide technological innovation and promote the energetic and environmental sustainability are favoured. Nowadays there are 73 members of the hydrogen strategy which are part of its Board and they belong to different sectors of interest.

Solar Heating and Cooling in an Energy Efficient Residential Building

Within a privately owned residential building a variety of technologies are implemented to reduce the energy consumption. Both a solar heating system and heat pump are connected to a boiler for the heating of water. This water is used as sanitary hot water. Space heating and cooling is achieved from fan coil units (FCUs); where hot or cold water circulates inside the convectors depending on the need. Finally, underfloor heating is established through a closed water pipe system, with a heat pump as heating source. The monitoring of the entire system takes place in one control unit.
