Coverage from the Estonian Hydrogen Days 2021

Estonian Hydrogen Days started on the 5th of July with Conference and Expo day, which followed with a day of Science in the University of Tartu, Institute of Chemistry.

Video Recordings:


Hydrogen Conference was held at Science Centre AHHAA

To warm up the visitors of the conference 4 hydrogen cars were presented to start with. It’s nothing new about using hydrogen in Estonia. The most experienced and oldest car was presented by Estonian hydrogen and electric vehicles enthusiast Enn Siemann. This 15 years car is still in service and has a notable tiny hydrogen consumption of 0.2 g hydrogen per 100 km travelled. Hydrogen equipment installed is delivered from Ecomotus and is one of the 30’th similar installations/retrofits of the vehicles on Estonian roads today.

Another 2 Mirais and also portable Hydrogen Refuelling Station was presented by Atrado. The latest state of the art technology Toyota Mirai 2021 was of great interest to visitors.

Collection of hydrogen technologies got an addition when the Deputy Mayor of the City of Tartu / Hydrogen mayor of Estonia arrived by a Hydrogen Bicycle. A Hydrogen drone by SKYCORP was landed next to the European Space Agency (ESA) rocket in the centre of the exhibition area. It had also received an update, apparently a world’s first, since it was also able to act as an off-grid generator (at the event, used to charge phones)

PowerUp Energy Technologies showcased actual hydrogen-powered off-grid generators meant to replace polluting and noisy diesel generators.

An unknown hydrogen device was also introduced, and the organizers are asking for help in identifying the device. It is said to be a hydrogen burner, but explanatory information is welcome 😏.

Roundtable discussion – What could be the Estonian solution?

Kristo Reinsalu, Ain Laidoja, Patrick Cnubben

Estonian solution, from where hydrogen is coming from and in which sector consumed.
For what we need hydrogen at all was the first question asked by moderator Tanel Talve.

Topics like Climate, transport on road and railway was discussed, but also aviation.
How to attract the private sector to get involved in Hydrogen Business?


“Jan Palmer, CEO of Xfly and President of the European Regions Airline Association, getting design inspiration for their planned hydrogen version of the ATR72-600”

Aviation in Europe, DG MOVE – Mr. Henrik Hololei.
Estonia – future for aviation?,
Minister of Entrepreneurship and Information Technology – Mr. Andres Sutt.
Aviation is one of the sectors difficult to decarbonise and using batteries to power aircraft is a real challenge. Hydrogen is foreseen as the solution provider for aviation by proposing hydrogen as a light energy carrier. “By 2035, aircraft with highly efficient propulsion systems and 30% less fuel consumption, could become available” was noted by Jan Palmer, CEO of Xfly.

Panel Discussion

Enn Lust, Grzegors Pawelec, Thomas Thomberg, Gunnar Nurk

If you, thought that scientists always agree with each other, then you are wrong.
Should we ban Internal Combustion Engines and gas turbines even for peak shaving in electricity networks?
Is a hydrogen-powered vehicle better and greener than Battery one ?
Hydrogen to balance electricity system and what is the cost of transporting hydrogen in the gas grid.

Tour of the demo centre and  laboratories

Warm welcomes and handshakes from the University of Tartu

Batteries, Supecaps, fuel cells and electrolyser cells were found in labs.
No secrets, tonnes of questions were asked (both, wise and foolish ones ), proper science-based answers were delivered in return.
But that’s not all. For enthusiasts were given a guide to making fuel cells at home (DIY).

Estonian Hydrogen IPCEI

Hydrogen Hub – New opportunities for seaport terminals.

Estonia receives 23 hydrogen project applications in IPCEI call with the total value of € 1.5 billion.

Despite the fact that the IPCEI call was open with very short notice only for 3 weeks, a lot of local interest was shown up by the Estonian private sector and industry.

List of projects.

Among many others Port of Tallinn foresees itself as a part of the green economy, proposing to develop a Hydrogen Hub in Port of Paldiski. Location is superior, connecting railway and the main road and also next to existing natural gas pipeline Baltic Connector (3400 MW) and HVDC interconnection to Finland (Estlink). About 13 GW Off-Shore wind parks have been proposed by developers, and the port could be the perfect place to accommodate construction and service points for wind parks.

Webinar “Hydrogen – Driver of the Estonian (green) future”

on April 14, 2021 at 10:00 – 12:40 (EEST) in ZoomRegister here

Many countries and organisations are in the middle of defining their hydrogen policies, roadmaps and strategies. Expectations are high that this old but newly re-discovered renewable energy carrier will play an important role in reaching the climate targets and it seems to be inevitable that hydrogen will shape our future energy sector. The question is: who will be the first to mobilise their forces and what happens to those who will not come along?

Hydrogen technologies save €350 million for rail

Hydrogen technologies, instead of catenary electrification need to be developed for our railway.

Stadler’s diesel powered multiple unit on estonian railway.

The Estonian Association of Hydrogen Technologies proposes to take up hydrogen technologies instead of catenary electrification. Hydrogen technologies would save €350 million for the state and compared to catenary electrification allows reaching Estonia’s climate goals by 3 times and renewable energy targets 6 times cheaper.

In the proposal sent to the ministries and parliament it is recommended to hold plans for electrification until a result is achieved on the deployment of hydrogen technologies on rail.

Reducing the carbon footprint in transportation and rail is one of the key challenges for Estonia in the coming years. The current plan is to achieve renewable energy goals by electrifying rail and it is expected to cost €428 million. The government made this principle decision in the summer of 2019 and Estonian Railways announced the procurement of design work in May this year.

The train traffic is too sparse on Estonian railway, which gives the opportunity for hydrogen technologies.

It is now the last chance to make a strategic decision to adopt hydrogen technologies on rail, make Estonia lead the world in this field of technology, save €350 million for other projects and help us reach climate- and renewable energy goals times cheaper. The failure to make forward-looking decisions now would mean decades-long entanglement with yesterday’s wasteful technologies and an aggravation of the development gap. However, the savings effect of the introduction of next generation technologies would provide an additional opportunity to make additional investments in railways, such as achieving the speed of passenger traffic suitable for a modern European country.

By implementing these proposals, perhaps by 2030 it will be possible to travel from Tallinn to Tartu by a more efficient, cleaner hydrogen train instead of a diesel. With the money saved, opportunities could be created to improve the railway in the direction of Narva and Tartu, perhaps even allowing passenger trains at speeds beyond the current ambition of 135 km/h but also allowing for more efficient services, additional trains and smarter systems.”

The proposals also indicate that hydrogen production based on rail transport can be further developed to include hydrogen for road vehicles. With the introduction of hydrogen technology on the railway, it is possible to create preconditions for covering the whole of Estonia with universal hydrogen infrastructure.

Estonian Hydrogen implementation vision

We have a plan H2 instead.

The Estonian Association of Hydrogen Technologies made a proposal to the Municipality of Tallinn to participate in the EU funded FCH Regions.
The project is fully funded by FCH JU and if approved, will provide the following:

  • Financial analysis
  • Technical analysis
  • Removal of market barriers
  • Expert advice on reaching both environmental and climate goals
  • Co-financing assistance on any project deployments.

We are not afraid of new insights!
Such FCH JU aid is estimated by us to be worth about 250 000 €. The project lasts for up to 12 months, would be just the first stepping stone and would help complete the upcoming Estonian Hydrogen Roadmap.

Eligibility criteria

  • Read and understand what is required of us and offered in return
  • Put the left foot forward
  • Accept the offered knowledge, assistance and know-how


The entire project is planned to be as observable as possible. Furthermore, additional “observers” will be included in all projects to get the latest updates and outcomes of the fulfilling of the set hydrogen economy visions.

Estonia’s task-force for the adoption of Hydrogen Technologies

Estonian Ministry of Environment initiated the hydrogen working group on 25th October 2019. The goal is to analyze and set up The Hydrogen Roadmap for Estonia. Usage of hydrogen and fuel cell technology are the key elements guiding Estonia to the carbon-neutral economy to achieve climate targets.

Hydrogen working group set up the first goals towards to carbon-neutral Estonia

The current meeting was to follow up Hydrogen Initiative signed by Estonia 2018 in Linz (Austria). Estonian Climate and Energy committee, which is led by prime minister analyzed the climate and economic impacts to achieve EU climate neutrality by 2050.
On the 03rd of October 2019 Estonia joined long term vision of EU climate neutrality 2050.

On kick-off meeting the first goal was set up, which is to issue Hydrogen Roadmap for Estonia. Next hydrogen working group meeting is scheduled in early November, where we are planning to discuss more specifically policy and technical measures to be considered.
