Who set up this information portal and why?
The h2-map.eu website is set up and managed by the Clean Hydrogen Joint Undertaking (Clean Hydrogen JU). The Clean Hydrogen JU is an EU body, set up under the form of a unique public private partnership that supports research and development and demonstration (RTD) activities in fuel cell and hydrogen energy technologies in Europe. Its aim is to accelerate the market introduction of these technologies, realising their potential as an instrument in achieving a carbon-clean energy system.
Fuel cells, as an efficient conversion technology, and hydrogen, as a clean energy carrier, have great potential to reduce carbon dioxide emissions, dependence on hydrocarbons and to contribute to economic growth. The objective of the Clean Hydrogen JU is to bring these benefits to Europeans through a concentrated effort from all sectors.
The three members of the Clean Hydrogen JU are the European Union (represented by the European Commission), fuel cell and hydrogen industries represented by Hydrogen Europe and the research community represented by Hydrogen Europe Research.
Where does the information on the portal come from?
The static information on site location of each HRS is updated manually by the HRS operators who have individual access to the operators' portal of the E-HRS-AS (GPS coordinates, opening hours, services on site, customer notification on events etc.). The dynamic availability information is an automated signal sent by either the HRS itself via an on-site hardware or via a software interface from the operators' plant monitoring system. The information on Clean Energy Partnership (CEP) approval is provided by the CEP working group.
How frequently is the station status updated?
HRS that send signals directly from the E-HRS-AS hardware provide availability status updates once per minute. HRS connected via the software interface provide availability data whenever there is a status change, or at a minimum, once every 60 minutes. The time stamp of the last status update is shown in the upper right on the pop-up box for each station.
Why are there stations without real-time status information?
HRS whose availability status is unknown are shown with a blue icon. There are two reasons the availability of an HRS could be unknown:
I know of an HRS which is not on this map! How can I add it to the map?
If you know of, or operate a publicly accessible HRS not shown on h2-map.eu we will be happy to add the station as soon as possible. You can contact us via email on e-hrs-as@clean-hydrogen.europa.eu.
Is there a mobile version or app of h2-map.eu?
The map has been optimized to fit both smartphones and tablets. There is currently no stand-alone app version of this map. On Android devices, however, an app version that displays the map in full screen separately from the web browser can be viewed by using the "Add to Home screen" function of your browser. To do so, simply touch the prompt that is presented on the first visit to the map (https://h2-map.eu/) or manually choose the option "Add to Home screen" in the Chrome menu bar at any later time. You may also decide to use a third party app that receives their information from the European database.
Will I be tracked when visiting the website?
The information provided by h2-map.eu is non-commercial and free for use. Our aim is to make this information readily available and used as widely as possible to support the roll-out of hydrogen mobility in Europe. We therefore do not track any visitors of our website. For more information please see our privacy policy.
May I refuel my hydrogen car at every station shown on the map?
Before driving to an HRS, you should check whether this station offers the correct fuelling option: 350 bar or 700 bar. Most cars are 700 bar and cannot be refuelled at a 350 bar HRS or can only be refueled to less than half their storage capacity. A 350 bar vehicle cannot be refuelled at a 700 bar station.
Please also check the authorization and the payment method before driving to the station as it may require an authorization card or special payment (e.g. pre-registration). In case you have any questions regarding authorization and / or payment, please use the contact information shown on the HRS site of interest.
How can I find out if I need to refuel 350 bar or 700 bar?
The pressure level of your car is indicated in the inside of the tank cap.
Why is the availability of my local station not shown on the map?
If your neighbourhood station is not shown on the map, we may not yet know of it. Please send us an email notifying us so we can connect it to our system and provide availability and site information in the future: e-hrs-as@clean-hydrogen.europa.eu.
It should be noted the h2-map.eu map only shows stations that allow public access and some site owners may refuse to participate and provide real-time availability information on the station. You may wish to ask the HRS operator and indicate your interest if you would benefit from this service.
The availability of my station is displayed incorrectly. Who can I contact to change it?
If the availability information of your station is displayed incorrectly, please do the following
Who may I contact in case I have a problem with refuelling my car or want to complain?
Please contact the helpline of your station, if you have any problems with refuelling your car or are not satisfied with the service of the station. You will find the phone number under "contact information" of the pop-up box of the station.
Is there on-site assistance at the HRS?
Some stations display information leaflets or stickers on-site explaining the refuelling process. If you need on-site assistance for refuelling you should contact the HRS operator via the hotline or ask service personnel on site.
I know other HRS availability maps that show different availability information. Why are these different?
There are a variety of different information systems in place, with different definitions for availability, including those that accept less frequent signal updates or use manual instead of automated signals. The main goal of our E-HRS-AS is to harmonize signal definition, the quality of the signal source, signal transmission and update frequencies, and share this information with all interested service providers.
If you encounter a map with different availability information, it can be that the service provider uses a different source of information or decided to only communicate parts of the harmonized information provided by the common European database. For example: You might find that availability information on another map is simply distinguished between "yes" and "no" although the E-HRS-AS platform shares a total of five different states (yes, no, limited, outside opening hours, unknown). Then it is likely that the three missing states are replaced by either "yes" or "no" according to a non-standard method.
What are the requirements to participate in the E-HRS-AS?
Please send an email to e-hrs-as@clean-hydrogen.europa.eu to express your interest in participating in the E-HRS-AS. Everybody is welcome to join.
What are my responsibilities as an owner or operator when participating in the E-HRS-AS?
First, you will need to name a contact person we can approach to organize the integration of your system into the platform. As soon as your HRS has been integrated, we will send you an access to the operators' platform to complete the static HRS site information in the portal and upload a picture of your station.
My HRS is not yet displayed on the map. Whom should I contact?
If you want to participate in the E-HRS-AS platform and have your station integrated, please send an email to e-hrs-as@clean-hydrogen.europa.eu
How can I change the station availability or metadata if it is incorrect or incomplete?
Every HRS operator or owner receives login credentials to the operator's portal where they are able to change the site information and issue or schedule customer notifications (metadata). A manual change of the station availability information is only possible when:
These changes can be done in the customer notification area. Manual changes of availability signals from "not available" to "available" are not possible.
I don't want to participate in the E-HRS-AS anymore. How can I cancel my involvement?
