The business case for ULTDH using the RELaTED concept – Residential & commercial customers, and heat producers

The use of ULTDH network in combination with CHP, reversible heat pumps for heating & cooling, solar systems, and waste heat increases the energy performance in every case. Photo by jiawei cui from Pexels The RELaTED project assessed the business case for ULTDH using a decentralized approach to heat production, i.e. heat can be collected from multiple points within the district heating (DH) network, not just one location. This assessment was applied to the DH customer case for residential and non-residential buildings, and heat producers (DH company). For DH customers, the use of building integrated solar panels, heat pumps, and triple function substations were applied to the DH networks of Belgrade, Serbia, and Tartu, Estonia. For Heat producers, [...]

District heating cost modelling

The district heating (DH) cost modelling assessment addresses the long-term energy planning of DHs, considering the evolution of systems towards greater efficiency, lower distribution temperatures, greater shares of renewable energy and the incorporation of distributed renewables in the context of an increase of nearly zero energy efficient buildings (NZEBs). Photo: Magda Ehlers (Pexels). The cost modelling is one of the topics included in the report D4.6 (download report D4.6 here >>). The RELaTED project has addressed this issue in WP4 – Economic feasibility & business analysis. The report, D4.6, serves as a summary of the main findings for this WP as it relates to the profitable operation of the RELaTED DH networks. Heat production costs The assessment is [...]

Lessons Learnt from Substation Inspection on Low Temperature District Heating Networks

by Antonio Garrido-Marijuan, Tecnalia, Basque Research and Technology Alliance (BRTA), Olaia Eguiarte, ENEDI Research Group, Department of Energy, Roberto Garay-Martinez, Tecnalia, Basque Research and Technology Alliance (BRTA), Margus Raud, Gren Tartu AS, 51014 Tartu, Estonia, and Indrek Hagu, Gren Tartu AS, 51014 Tartu, Estonia. Abstract Tartu DH network (Estonia), with the demo area highlighted in blue. District heating networks are considered to be a key element for the decarbonization of Europe. The RELaTED project seeks to contribute to the decarbonization of these infrastructures with the demonstration of low temperature district heating networks. One of the demonstration sites consists of more than 50 substations within a subsection of a larger network in the city of Tartu (Estonia), where the [...]

“RELaTED project has proven that de-carbonised and efficient district heating can be achieved”

Roberto Garay, RELaTED Project Coordinator RELaTED has been active since 2017. At that time, we envisioned a future where de-carbonised and efficient district heating could be achieved. We have actually done so. By the end of 2021, we have proven the feasibility of our concept. Furthermore, we have applied it in several networks representative of the diverse District Heating context in Europe. With progressive distribution temperature reductions, our experience in the Tarkon area is now extended over the full DH network in Tartu. Together with our local partner GREN, RELaTED has already tested the capacity to reduce distribution network loss by ca 5%. Belgrade has seen the renovation of the DH network in Vinogradski Venac. With this modernization, [...]

VIDEO: Conoce el innovador sistema de calefacción urbana implantado en Iurreta (Bizkaia)

El innovador sistema de calefacción urbana implantado en el complejo de la Ertzaintza en Iurreta (Bizkaia) puede distribuir calor a una calefacción de distrito a ultra baja temperatura, lo que posibilita ahorrar energía y extender el uso de las energías renovables. Se trata de una district heating (calefacción urbana) que suministra agua caliente sanitaria, así como calefacción y refrigeración, a un complejo de la policía vasca compuesto por un conjunto de 14 edificios. Estas novedosas instalaciones, desarrolladas en el marco del proyecto europeo RELaTED, han sido financiadas por la Unión Europea y el Gobierno Vasco, con la colaboración de un total de 14 empresas e instituciones de 8 países, entre ellas, Ente Vasco de la Energía, Tecnalia, Innometal o NIBE.

RELaTED presenta el innovador sistema de calefacción urbana implantado en Iurreta

El proyecto RELaTED ha presentado la innovadora infraestructura desarrollada en las instalaciones de la Ertzaintza, en Iurreta (Bizkaia). La puesta en funcionamiento de este sistema demuestra que se puede distribuir calor a una calefacción de distrito a ultra baja temperatura, lo que posibilitará ahorrar energía y extender el uso de las energías renovables en otras zonas de Europa. El Vicelehendakari y Consejero de Seguridad, Josu Erkoreka, y la Consejera de Desarrollo Económico, Sostenibilidad y Medio Ambiente, Arantxa Tapia, han visitado las instalaciones de la Ertzaintza en Iurreta (Bizkaia) para conocer los resultados del proyecto de investigación europeo RELaTED, Renewable Low Temperature District, en el que participan catorce empresas e instituciones de 8 países europeos. El Gobierno Vasco ha invertido 813.630 euros en la puesta en [...]

Seminario: Estudio de consumo de energía mediante métodos de análisis de datos

El pasado mes de noviembre, Roberto Garay, coordinador del proyecto RELaTED, participó como ponente junto con Mikel Lumbreras, en los cursos de doctorado en Eficiencia Energética y Sostenibilidad en Ingeniería y Arquitectura (EESIA), que imparte la Universidad del País Vasco. Presentacion CursoBajo el título “Estudio de consumo de energía mediante métodos de análisis de datos”, se abordaron diferentes aspectos de la medición de cargas términas en edificios: sistemas, herramientas y aplicaciones. Durante el seminario, los asistentes tuvieron la oportunidad de conocer las aplicaciones prácticas de estos sistemas a través de las mediciones reales, como las desarrolladas para el proyecto RELaTED. Los ponentes realizaron la revisión de un número relevante de métodos aplicados desde la época del PRISM, pasando por el [...]
