Hydrogen Refuelling Infrastructure
Overview
H2ME stations deployed
45+ stations are planned as part of the project
This €170 million demonstration project is co-funded with €67 million from the European Union's Horizon 2020 programme through the Fuel Cells and Hydrogen Joint Undertaking (now Clean Hydrogen Partnership), a public private partnership supporting fuel cell and hydrogen energy technologies in Europe.

This project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking (now Clean Hydrogen Partnership) under Grant Agreement No 671438 & No 700350.
Aside from the actual vehicle technology the creation of a fuelling station network is essential to the market development of these new vehicles. FCEVs can be refuelled in 3-5 minutes at a hydrogen refuelling station (HRS), offering refuelling times similar to those of conventional petrol or diesel cars.
H2ME has helped to expand the limited number of networks in each partner country.
Safety
When hydrogen is in a tank, there is no danger of explosion. Hydrogen is an energy source that is – as is the case with every other fuel – flammable in contact with air. Risk assessments show however, that hydrogen is no more dangerous than petrol or natural gas for example. In addition, hydrogen has also been used commercially safely for more than 100 years in large quantities, including in the chemical industry.
The energy content of hydrogen tanks in vehicles is typically less than that of regular petrol or diesel vehicles. The automotive industry has agreed globally on a pressure of 700 bars for hydrogen in cars – the pressure of hydrogen storage systems is mechanically controllable. Hydrogen vehicles driven in demonstration trial programmes have all undergone the automotive manufacturers’ complete development cycle, including crash tests, and are cleared for road use. The vehicles are therefore as safe as conventional vehicles.
Technology and advancements
Various refuelling strategies were investigated under H2ME:
Grid balancing services and optimisation strategies. Some of the HRSs to be deployed under H2ME will be designed to provide grid balancing services and other smart electricity price optimisation strategies.
Hydrogen production off site with hydrogen delivery by tanker, which is how current petrol and diesel supplies are transported to stations. These stations have the advantage to be more easily integrated into current forecourt stations and can be less expensive to commission.
Hydrogen production on site with hydrogen generated using surplus renewable energy supplies and water using an electrolyser. These stations have the advantage to offer renewable clean fuel and eliminate the need for fuel deliveries.
Hydrogen refuelling network
FCEVs and the associated refuelling infrastructures were at that time in the very early stages of the market introduction. The current priority was to introduce vehicles in markets where a strategy was in place to support their use with an appropriate infrastructure for hydrogen fuel supply, distribution and sale.
In the early years, this infrastructure was inevitably expected to grow slowly as demand for vehicles increased. During the introduction phase (i.e until 2020), the number of stations remain low but will increase faster than the demand for hydrogen to ensure an adequate hydrogen refuelling network coverage allowing FCEV sales to a broader market. This requires a deployment of 100’s of stations per country.
The HRS investment costs will remain relatively high in the early years and with equivalent low utilisation, station investors require support in the early years to justify the challenging early investments in the stations before vehicles arrive in large numbers. As demand on the stations increases, they can become profitable investments.
A mature market (i.e self-sustaining) is expected to be reached by 2025, beyond which point all that will be required to sustain this environmentally valuable market is a favourable regulatory regime.
