Behind every innovation and new technology there is a human: case green hydrogen in Finland

Green hydrogen is playing a key role in shaping Europe’s clean energy future. The EU has set an ambitious goal to produce 10 million tonnes of green hydrogen by 2030 — and Finland is set to deliver 10% of that target. Turning that promise into reality needs experts.

Let me start by briefly explaining the technical background of green hydrogen. Green hydrogen, produced using renewable electricity without carbon dioxide emissions, stands apart from grey and blue hydrogen, which rely on fossil fuels or nuclear power. At the heart of green hydrogen production lies electrolysis — a process where water is split into hydrogen and oxygen using electricity. A crucial device in running a hydrogen plant is the electrolyser – a true masterpiece of engineering. But even this elegant process doesn’t mean much without people, because no substance or invention will save us unless there’s a human in between to make it work.

Hydrogen is the smallest molecule in existence, notoriously hard to contain, and requires engineering solutions that can withstand extreme pressure and stress. This is not plug-and-play technology, it’s precision work.

Human expertise is essential in Finland’s first green hydrogen plant

In the small town of Harjavalta in Western Finland, Enersense operates and maintains Finland’s first green hydrogen plant, owned by P2X Solutions. The plant began its hydrogen production in 2025. With a nominal production capacity of 20 megawatts and a dedicated team of about 50 Enersense professionals, the plant is remotely controlled around the clock and operated on-site. Our experts ensure continuous, safe and efficient performance, every day, every hour.

We’ve been involved in the entire construction process of the plant — from installing the electrolysers to building the complex piping systems and large, high-spec steel structures required to handle hydrogen’s demanding properties. We’re also responsible for transferring the produced hydrogen to the customer safely and reliably.

Technology, science, and innovation are essential — but they aren’t enough on their own. A green hydrogen plant doesn’t build, run or deliver on its promise without people. Behind every valve, every pipe, and every line of code are skilled professionals making it all work. Our people are the reason this plant operates.

We are proud to be the first company in Finland with the capabilities to design, construct, operate, and maintain a green hydrogen facility. We have also strengthened the electricity grid around it by building substations and high-voltage lines, thus laying the groundwork for the green transition.

Without people, even the finest piece of engineering wouldn’t run. That’s why we must take care of people’s skills and well-being – and be proud of the expertise we have here in Finland.
