Hydrogen as an energy revolution
in industry and transport
The hydrogen economy represents a groundbreaking approach to sustainable energy, where hydrogen is used as a clean, flexible, and efficient energy carrier. This technology offers hope for reducing dependence on fossil fuels, provides an alternative for storing excess renewable energy, and can play a key role in decarbonizing various sectors—from transport to industry.
The implementation of the JESS hydrogen economy project is currently underway at the EMPARK Trnava site, as a pilot project for hydrogen production using a 1 MW PEM electrolyser. The aim is to produce high-quality green hydrogen intended for public, regional, and freight transport vehicles as a tool to improve the environmental situation in Slovakia by reducing the transport sector’s carbon footprint.
In its second phase, the project’s annual production volume will reach up to 160 tons of hydrogen. This amount of hydrogen, when used in suburban and urban bus public transport, can support transport operations covering up to 1.3 million kilometres per year, equivalent to the annual mileage of approximately 20 buses.
The pilot deployment of hydrogen technology in Slovakia aims to support the development of permitting and siting rules for such technologies in built-up areas. It also seeks to establish the core infrastructure necessary for the production and distribution of hydrogen in Slovakia, primarily generated from domestic renewable energy sources.
The project will contribute to the development of national know-how for the effective production, storage, and subsequent distribution of green hydrogen. In its final stage and full scope, the project is expected to achieve annual CO₂ savings of up to 1,000 tons.
Key benefits of the hydrogen economy
for a sustainable future
Reduction of greenhouse gas emissions
The hydrogen economy offers a way to significantly reduce greenhouse gas emissions, especially when hydrogen is produced from renewable energy sources. Using hydrogen as a fuel in transport and industry can replace fossil fuels and substantially lower carbon emissions.
Diversification of the energy mix
The hydrogen economy enables diversification of the energy mix. Hydrogen can be used as a storage medium for surplus energy from renewable sources, increasing their efficiency and reliability. This helps to balance fluctuations in energy supply from renewables such as solar and wind power.
Support for sustainable transport
Hydrogen fuel cells offer a promising alternative to fossil fuel-powered vehicles. Hydrogen vehicles produce zero emissions, with water being the only byproduct of their operation. This can have a significant impact on reducing air pollution in cities and improving air quality.
Support for sustainable industry
The hydrogen economy can also have a positive impact on industrial production by providing clean fuel for processes that have traditionally relied on fossil fuels. This includes the production of steel and cement, as well as other industrial processes that are major sources of carbon emissions. Using hydrogen in these applications can significantly contribute to the decarbonization of industry.

How does
the hydrogen economy work?
The hydrogen economy is a system in which hydrogen is used as a key energy carrier for various applications, including transport, industry, and heating. Hydrogen can be produced in several ways, most commonly through electrolysis – a process in which an electric current is used to split water molecules into hydrogen and oxygen.
The produced hydrogen can then be stored and transported, either in gaseous or liquid form, to locations where it is used as an energy source. In the transport sector, hydrogen is used in fuel cells, where it reacts with oxygen from the air to generate electricity to power vehicles. This process produces only water as a byproduct, helping to reduce emissions from transportation.
In the industrial sector, hydrogen can be used as a clean source of heat or as a feedstock for chemical processes. The benefits of the hydrogen economy lie in its flexibility, its potential to reduce dependence on fossil fuels, and its contribution to achieving climate change goals.
