Fuel Cells Works, Stargate Hydrogen to retrofit & deliver 40 hydrogen fuel cell locomotives to rail company Operail in Estonia

Hydrogen solutions company OÜ Stargate Rail has signed a letter of intent with AS Operail, the international rail company, to convert diesel-electric locomotives to zero-emission fuel cell electric locomotives.

As part of the retrofit, the diesel gensets that power the locomotives will be replaced by a zero-emission powertrain consisting of polymer-electrolyte-membrane fuel cells and lithium-ion batteries. After the conversion, the locomotives will operate as shunting locomotives.

The partnership with Operail is planned in two phases. Initially, a prototype of a fuel cell electric locomotive will be constructed by the end of 2022. In the second phase of the project, the parties intend to convert an additional 40 locomotives to fuel cell power. Each converted locomotive will save 370 tonnes of CO2 emissions per year, equivalent to the annual emissions of 80 average passenger cars.

Rainer Küngas, Chief Technology Officer at Stargate Rail, commented: “Retrofitting ageing diesel locomotives to zero-carbon alternatives is already an economically sustainable solution and will be even more so in the future. Retrofitting also allows the reuse of existing diesel-electric locomotives that would otherwise end up as stranded assets once they no longer meet future emission standards.”

Raul Toomsalu, Chairman of the Management Board at Operail, said: “Operail has focused its activities on environmental sustainability. In Estonia, this is achieved via electrification of the main railway lines, but this does not resolve the issue of emissions in shunting operations. The team at Stargate has outstanding international experience and world-class technological capabilities, while our professionals at the Tapa depot have the skills and knowledge for building modern locomotives. As a result of this collaboration, we can offer innovative and environmentally sustainable solutions in all our target markets.”

Henrik Hololei, Director-General for Mobility and Transport at the European Commission, added: “Even if rail is already largely electrified, energy-efficient and our most sustainable transport mode, it is certainly no time to be complacent. For example, around 20% of our engines in the EU still run on diesel. There is no doubt that we need innovative solutions to enable the wider use of alternative fuels such as green hydrogen. We are keen on exploring, together with Shift2Rail and Fuel Cells Hydrogen Joint Undertakings, how fuel cell and hydrogen can be integrated into rail operations and how to turn ideas into actual projects and applications.”

The completion of the first hydrogen locomotive prototype is planned for the end of 2022.

OÜ Stargate Hydrogen is a privately owned company developing turn-key green hydrogen solutions in Estonia. Stargate Rail’s core business is the conversion of diesel-electric locomotives to fuel cell alternatives. Stargate is aiming to become a global leader in hydrogen solutions. Innovation is an essential tool that will strengthen the company’s ambitious growth strategy, with activities focused on developing the next generation electrolyser and fuel cell solutions for locomotives. Stargate Hydrogen is a member of European Clean Hydrogen Alliance, Estonian Association of Hydrogen Technologies and Latvian Hydrogen Association.

Operail is an Estonian state-owned railway company whose main business activities are freight transport, repair and construction of locomotives and wagons, and rolling stock rental. In addition to the parent company AS Operail, the group also includes Operail Holding OÜ, Operail Repairs OÜ and AS Operail Leasing, as well as subsidiaries in Finland – Operail Finland Oy and Operail Leasing Finland Oy. Operail Repairs OÜ main business is the maintenance of rolling stock and the construction of locomotives, AS Operail Leasing and Operail Leasing Finland Oy are wagon rental companies, and Operail Finland Oy offers freight transport services in Finland.
