How EODev Connects Its Hydrogen Generators Worldwide Through IoT

Decarbonization doesn’t happen from a desk. It happens in the field – at ports, on construction sites, at the foot of remote 5G towers. For EODev, a pioneer in hydrogen-powered electric generators, IoT connectivity isn’t an add-on: it’s the central nervous system of their entire operation.

An exceptional industrial challenge

EODev manufactures next-generation industrial power generators – not diesel-powered machines, but hydrogen-fueled systems designed to cleanly and silently power critical infrastructure: telecom towers, vessels, construction sites.

Their machines are deployed worldwide: France, Belgium, the Netherlands, the UK, Italy, Spain, Dubai, Saudi Arabia. Varied environments, often isolated, often mobile. On a vessel offshore, a 5G tower in a coverage gap, or a construction site with no fixed network infrastructure.

The common thread across all these deployments? The need to transmit operational data in real time, wherever the machine is located.

IoT at the heart of the customer experience

Cellular connectivity isn’t just about knowing whether a machine is running. At EODev, it powers an entire customer service layer.

Every connected generator feeds a dedicated after-sales portal, accessible to end clients. This portal displays real-time operational data: temperatures, pressures, fault codes, and operating history. A technician in Paris can diagnose a machine in Riyadh without travelling, and guide the on-site operator through the fix.

But the use goes further. The data collected also drives:

• Internal R&D: digital modelling of machines, comparison between real and expected behaviour, continuous product improvement.
• Client reporting: every connected machine generates an energy performance and avoided emissions report. The results are concrete and measured – EODev’s hydrogen generators avoid more than 70% of CO₂ emissions and diesel consumption compared to traditional generators during operational phases. For rental companies and operators who need to demonstrate their environmental impact to clients and shareholders, this data isn’t a nice-to-have: it’s the proof.

Connectivity, then, is not a technical tool. It is a commercial and environmental argument.

The SIM card as the deployment standard

In such varied environments, WiFi is rarely available. Ethernet is out of the question for mobile machines. The SIM card has become the default solution.

Before choosing Transatel, EODev evaluated several providers. Two criteria proved decisive: a usage-based billing model, suited to machines that don’t run continuously and whose data consumption varies, and unified multi-country coverage, making it possible to deploy the same SIM across France, Belgium, the Netherlands, or Dubai without managing local operator agreements. Their previous provider could not meet both requirements at once.

EODev selected Transatel’s multi-operator SIM cards, integrated directly into the data loggers embedded in each machine. The result: seamless global coverage, centralised fleet management from a single platform, and usage-based billing suited to their operational reality.

“The SIM cards are integrated directly into our machines and embedded computers. We never hear about them – which means they work. That’s a good sign.” – Sébastien Trédan, EODev.

Managing a global fleet without complexity

One of the challenges of international deployment is managing data costs across countries. EODev chose a pay-per-use model – each SIM consumes what it consumes, without volume commitments. An approach that fits their reality: machines that aren’t always actively running, and stable, predictable data consumption thanks to a systematic transmission program.

The Transatel platform allows them to monitor consumption per SIM, per machine group, and per geography – a useful level of granularity for anticipating costs as the fleet grows.

Connectivity as proof of decarbonization

There is a dimension often underestimated in industrial IoT projects: the evidentiary value of data.

At EODev, this value is measured and documented. Every connected machine produces an energy performance report that precisely quantifies CO₂ emissions and diesel consumption avoided – with a demonstrated impact of over 70% compared to a traditional generator. These are not estimates: they are calculated from real data transmitted by each machine through Transatel connectivity.

For companies renting or operating these generators, this is a decisive argument – for their ESG reports, their clients, their shareholders. Without reliable connectivity, these reports don’t exist. With it, EODev turns every hour of operation into documented proof of environmental impact.

What this use case illustrates

EODev is a perfect example of a new type of IoT customer: industrial manufacturers who don’t want to make connectivity their core business, but need it to make their own service smarter and more credible.

For these players, the criteria for choosing a SIM partner are straightforward:

• Reliable global coverage, without managing operator agreements country by country
• A simple management platform that doesn’t require a dedicated team
• Flexible billing, suited to variable volumes and usage patterns
• A responsive partner when a technical issue arises

That’s exactly what Transatel brings to EODev – and to every equipment manufacturer connecting their machines to better serve their customers.
