Estonia’s Olgina Airport, located near Narva, and the European company COOLERGY, specialising in hydrogen solutions, performed Estonia’s first charging of aircraft batteries on the airfield using a COOLERGIZER mobile hydrogen generator. 
The Wilga 35A aircraft, which provides transport and drop of parachutists, was the first aircraft in the history of the Baltic States to be charged with a Coolergizer hydrogen generator.
‘We have been interacting with the Olgina Aerocomplex for several years, discussing a hydrogen aerotaxi project between Estonia’s Narva and Finland’s Kotka,’ says CEO of COOLERGY, Kirill Lyats.It’s only a 15-minute flight. And now, the first hydrogen has arrived in the field. For now, in an electric generator. As you probably know, aircraft use ground power before launch and after landing to conserve on-board fuel, and before launch to optimally switch on on-board generation. External power is also used during repairs. We already have orders for such facilities specifically for servicing business jets in Spain, but for now we decided to test the possibility itself. And, voila, the contact is there. Many thanks to Vadim Orlov, aviation lover and enthusiast of Narva city, for many years of co-operation and help in this event”.
COOLERGIZER, the name of the electric generator, is an environmentally friendly and low-noise mobile charger powered by hydrogen fuel cells.
COOLERGIZER is designed to power and charge aircraft at airports, ships at ports, mobile refrigerators, electric vehicles and other applications.
The presented COOLERGIZER has an output power 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 designed for autonomous power supply or recharging of objects remote from public networks and without access to “green” energy.
Earlier it was reported that local companies intend to begin construction of a modern airport and business park on the basis of the Olgina airfield, as part of the ER201 “Narva-Olgina Air Gateway” project.

For this purpose, the Ida-Virumaa Investment Fund (IVIA) submitted an application to the Estonian Ministry of Regional Development and Agriculture to transfer the site within the planning boundaries to the ownership of IVIA, Gazeta.ee wrote. So “green”, mobile energy will be very useful in this complex.
Earlier, the COOLERGY team reported that on April 22, 2025, they began the “Great Hydrogen Journey” with COOLERGIZER from Tallinn to Madrid.
The first stop of the journey was the site in front of the Eesti Energia/Enefit central office 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.
Representatives of COOLERGY and Enefit/Eesti Energia, who are already cooperating on hydrogen projects in Estonia, discussed further steps to hydrogenate the economies of the Baltic states.
Volunteers — owners of electric cars — came to the presentation. Thus, Nikita Kirichenko and Natalia Efimova became the first drivers in the Baltics whose electric cars were charged by a hydrogen electric generator. The use of COOLERGIZER allows to completely abandon the use of fossil fuels for the supply of electricity and autonomous power supply or recharging of objects remote from public networks where there are no local power plants from renewable sources, the manufacturer claims.
