Coolergy has started an important stage in the production of the world's first LH2 shunting locomotive

COOLERGY, which is realising the project of converting the old diesel-electric TGM4 shunting locomotive to liquid hydrogen, has started the work of dismantling the old and assembling the new equipment of the locomotive in the port of Riga.

Previously COOLERGY stated, that the first refurbished TGM4 with a hydrogen power plant is expected to be ready for operation in the port of Riga by the end of the 2024 year.
The agreement between COOLERGY and Hanko Trans, Estonia, was signed in early 2024 to upgrade 12 TGM4 diesel locomotives operating in Riga. Each vehicle will be equipped with four 80 kW Toyota fuel cells. The Riga Free Port has agreed to pilot operation, so it will continue to use all 12 locomotives after the conversion to liquid hydrogen.
Most of the work to convert the diesel locomotives will be carried out in Riga, while the fuel will be produced in production and liquefaction facilities with an output of up to 2 t of hydrogen per day, to be built by the Spanish company in Estonia.
