About Us

Since the CleanMobilEnergy project’s official start date in 2017, the city of Arnhem in the Netherlands has been making strides towards connecting renewable energy to their maintenance harbour’s medium-sized ships adjacent to the city’s industrial area through a “cold ironing” (shore-to-ship charging) system – which is optimised through REMove. This means that instead of using the ship’s own diesel engine, electricity is provided by the nearby solar and wind fields, with REMove balancing the inflow and production of energy to the harbour.

REMove has been integrated across the Arnhem City Pilot with the core of the pilot’s attributes integrated into the city’s industrial area nearby the 14 MWp solar plant including 4 wind turbines of 6.5MW.

Connected to the solar field, Arnhem has jointly developed and or connected to the REMove system:

1. A Lithium-ion storage facility of 500 kWh, including all hardware (cables, small buildings etc.);
2. A cold ironing (shore to ship power supply) installation for 18 river barges in the ‘Nieuwe Haven’;
3. All public charging stations in the city of Arnhem (about 250);
4. A REMove-system location (computer plus software) to govern the Arnhem City Pilot system energy flows.

One notable feature about this pilot city is its charging plazas. The charging plaza featured in the images above was installed in Arnhem for public use and is composed of 16 charge points on one grid connection.

A computer directs different levels of power to different vehicles, depending on the vehicles' need. Additionally, Arnhem aims to connect cold ironing (shore-to-ship power) to solar and wind field through effective RES storage and the REMove system.

Notable to this REMove testbed location is that energy generation, storage and energy-consuming devices are remotely placed and have individual electricity connections, contacts and direct interaction is limited. In contrary to situations where these devices exist behind one connection, metering and billing system.

With REMove, the utilisation of energy provided by the Arnhem solar and wind fields will be further enhanced, aiming to reduce CO2 emissions on an even larger scale, and to investigate how the ships in maintenance and EV charging stations will use the highest percentage of locally made renewable energy.

REMove has also been tested in the City Pilot of Nottingham, a medium sized city in the UK with a large share of its energy production sourced from renewable energy sources. Nottingham has large ultra-low emission vehicles (ULEV) funds, as well as the UK’s largest solar installation and the first Municipal Energy Company. Even before CME, Nottingham has a medium sized renewable energy storage capacity (is the most energy autonomous city in the UK), as well as electric vehicles and bi-directional chargers in controlled areas or depots.

In Nottingham, electric vehicles themselves are used to power the buildings and depot by using innovative bi-directional chargers controlled by the REMove system.

REMove has optimised the bidirectional energy production and consumption flow within the context of:

1. 40 fully electric vans and cars operated by Nottingham City Council and based overnight at the depot;
2. Installation of a fast-charging hub with up to 5 Electric Vehicle charging points;
3. Installation of 88kWp of PVs;
4. The PV will feed into the building’s electrical infrastructure and be used either for EV charging, or in the building’s current energy load;
5. Installation of a 378kW/676kWh lithium ion battery controlled by a site energy management centre;
6. Installation of 40 “vehicle 2 grid” (V2G) bidirectional charge points to enable the vehicles to be used for energy storage and grid balancing.

Piloted the REMove system in Stuttgart, the capital of the German state of Baden- Württemberg, has provided data on light electric vehicle (LEV) mobility in connection to the REMove system at church organisations. This unique mobility use case has enabled:

1. CO2 reduction by replacement of ICE Cars with LEVs powered by renewable energy;
2. Testing of an attractive system to quickly implement Change of ICE Cars to LEVs based on flexible MaaS turnkey elements;
3. Trial REMove in the context of the vehicle fleets operated by churches and church organisations;
4. Potentially industrialise the key elements utilising the power of the REMove system.

The final testbed site of the REMove system, Schwäbisch Gmünd, is a small city in Germany with a population of around 60,000 citizens. Although Schwäbisch Gmünd boasts the 2nd largest solar park of Germany, the city utilises a small amount of renewable energy in relation to its total energy production. Here, there are small scale RES storage facilities, and electric bikes are being used in residential areas.

The REMove system was tested here in the following contexts:

1. Various houses with solar PV systems installed and supplied with domestic battery storage, all linked to the REMove;
2. Each house will include 84 battery tubes connected to the installed PV, focused on charging low emission vehicles (LEVs), especially for short distances;
3. Charging and exchange stations for batteries serve as a temporary storage and are integrated in the electricity grid;
4. Analysis of data usage and electricity flows, etc.;
5. Establishment of a lease and rental vehicle infrastructure with integrated LEV and battery exchange stations;
6. Use of smart battery storage system for grid regulation.

The goal of REMove in the context of Schwäbisch Gmünd has been to induce a high level of energy autonomy at small city scale. REMove has allowed for this by managing various solar installations and implementing LEV-charging infrastructure and buildings where energy is consumed and stored. The REMove system will manage and optimise this energy production and consumption.
