Alternative Energy Hub
The Port of Antwerp selected ENGIE as concession holder and commercial operator for 30 years to develop a new concept: an Alternative Energy Hub for transport and mobility in the Port of Antwerp.
The project is a cooperation between multiple ENGIE Group subsidiaries. As the concession holder, ENGIE LNG Solutions will take care of the commercial exploitation. ENGIE Fabricom will build the facility, and for maintenance and operation it will call on ENGIE Cofely. It will be a zero-emission facility thanks to the boil-off optimisation process (see below). The first part of the infrastructure will be operational by the end of 2017.
In order to be able to implement this project, a consortium was set up consisting of multiple companies (ENGIE LNG Solutions, Antwerp Port Authority, Anglo Belgian Corporation (ABC), Somers NV, Fockedey Truck S.A., Instituut voor Landbouw- en Visserijonderzoek (ILVO), Vlaams LNG Platform and Laurentia Rijn BV/ Danser Group BV) that want to be involved in boosting the sustainability of the mobility sector and to contribute to the energy transition.

How the Alternative Energy Hub will work?
The hub will contain different parts:
- a LNG shore-to-ship LNG bunkering station for inland navigation
- an LNG and CNG filling station for road trabsport
- Charging stations for electric vehicles
LNG shore-to-ship bunkering station for inland navigation
The LNG bunker and filling station will consist of a standalone unit with the appropriate permanent LNG storage capacity and a flexible bunkering arm. Depending on the volume and the size of the connector on the ship’s LNG fuel tank, one or both pumps can be used for bunkering. The same connection will be used to connect an LNG feeder ship for filling the LNG storage tank.
LNG & CNG filling station for road transport
An LNG and CNG filling station for trucks, buses and cars will be built at the same location. There will also be a permanent storage tank for the LNG and CNG station. The CNG will be produced on the site itself from the LNG storage tank via the boil-off management process (see further). There will be one island with two LNG dispensers for trucks and one island with two CNG dispensers for trucks, buses and cars. Diesel will also be available on the site, primarily to supply dual-fuel trucks with their fuels.
Charging stations for electric vehicles
The site will have rapid charging facilities for electric vehicles. The electricity for this part of the facility will come from the boil-off gas management system. The gas created from heating up LNG will be used as fuel by a generator that produces the electricity for the charging stations.
Zero emission installation
When LNG (-169°C) is stored, and not drawn off, it warms up under the effect of ambient heat and becomes gaseous and evaporates (boil-off gas). This causes a slow pressure build-up in the storage tank. In order to control this process, the boil-off gas can be used efficiently as a fuel for generating electricity that will then supply electric charging stations or be injected into the grid. If there is no demand for electricity, the gas can be cooled back down, and becomes liquefied. It is then channelled back to the LNG storage tank for reuse. Finally LNG can efficiently be transformed to CNG.
This entire optimisation process ensures that there are no atmospheric emissions.
