A hydrogen generator on a car trailer has started a presentation tour of Europe, from Tallinn to Madrid 

The Spanish company COOLERGY, specialising in LH2 solutions, has introduced COOLERGIZER, an environmentally friendly and low-noise hydrogen fuel cell mobile charger.
COOLERGIZER is designed to power and charge aircraft at airports, yachts in harbours, mobile refrigerators, electric automobiles and other applications. 
COOLERGY team reported that it began the Great Hydrogen Voyage with the COOLERGIZER from Tallinn to Madrid on 22 April 2025.
The first stop of the journey was the area in front of the central office of Eesti Energia/Enefit in Tallinn. Coolergy S.L. specialists demonstrated to partners from the largest energy company in the Baltics the efficiency of a mobile charger that uses hydrogen as fuel.
Volunteers – owners of electric cars – arrived for the presentation. Thus, Nikita Kirichenko and Natalia Efimova became the first drivers in the Baltic States whose electric cars were charged by a hydrogen electric generator. Using COOLERGIZER allows to completely eliminate the use of fossil fuels for the delivery of electricity where there are no local power plants from renewable sources.
Representatives of COOLERGY and Enefit/Eesti Energia, who are already cooperating on hydrogen projects in Estonia, discussed further steps to hydrogenize the Baltic economies.
The presented COOLERGIZER has a power output of up to 40 kW with the possibility of increasing to 80 kW, as well as a voltage of 27 to 380 V. It is intended for autonomous power supply or recharging of objects remote from public networks and without access to green energy. 
Autonomous energy capacity of COOLERGIZER – 360kWh ( infinite when external hydrogen cylinders are connected). Approximate system mass -600kg. Service life -10 years.
