Energy Hub

Energy-Hub for residential and commercial districts and transport

E-Hub is a collaborative €11.66 million European project, part funded by the EU, which aims to demonstrate the full potential of renewable energy by providing 100% on-site renewable energy within an "Energy Hub District". ICAX has been invited to join the collaborative project for its expertise in pavement solar thermal collectors.

Energy Hub

An Energy Hub is a physical cross point, similar to an energy station, in which energy and information streams are coordinated across a local Smart Grid, and where different forms of energy (heat, electricity, chemical, biological) are converted between each other or stored for later use.

The Energy Hub exchanges energy via the smart energy grids between its members (households, renewable energy plants, offices), who may be both consumers and suppliers. The members exchange information on their energy production and energy needs with the Energy Hub. The Hub then distributes the available energy in the most efficient way.

To match supply and demand, the Energy Hub converts and stores energy and performs load shifting. The members will be connected to the Energy Hub by means of bi-directional energy grids (low and high temperature heat grids, electrical grids (AC and DC) and gas grids (hydrogen, biogas, syngas).

Renewable energy may be generated by individual members (e.g. from PV on residences) or by central means (a ground source energy or a large combined heat and power plant) located within the district that may be fueled by solar energy, biofuel or hydrogen.

The Energy Hub brochure illustrates the ideas that have been studied in the E-Hub project.

District Heating and Cooling from On-Site Renewable Energy

The Energy Hub idea covers all types of energy flow, from heating and cooling to electricity, biogas and hydrogen, and may be connected not only to households but also to (electric) cars, commercial buildings and industry.

The aim of the project is to develop the Energy Hub as a system, to develop technologies that are needed to achieve the system successfully, to develop business models in order to overcome institutional and financial barriers, and to demonstrate a live Energy Hub with further feasibility studies to extend the principle.

ICAX joins a distinguished group of companies from across the European Union researching into a successful Energy Hub District, led by TNO of the Netherlands.
