HYDROGEN-POWERED CHP PLANT FOR SERBIA POWER PLANT

Innio will provide a 1 MWe combined heat and power plant (CHP) which runs on a Jenbacher engine fuelled by hydrogen produced 100% from an array made up of solar photovoltaics.

A Jenbacher J420 engine has been chosen by PAN-LEDI d.o.o. for the project in Nova Pazova, Serbia. The contract calls for the delivery of a containerised CHP unit built to generate about 1 MWe.

The electricity will be used by PAN-LEDI for its electric vehicle (EV) charging station, with excess energy provided for the Serbian grid and the engine waste heat sold to a nearby commercial customer.

The CHP unit consists of a Jenbacher container and a complete heat recovery system. The Jenbacher CHP plant is expected to be delivered and commissioned in late 2023.

The Jenbacher J420 is based on Innio’s proven Type 4 platform of more than 6,000 delivered engines generating about 7 GW of power worldwide.

Leading the way with next-generation technology innovation, the J420 delivers as much as 4% more output - up to 1,560 kW - and up to 1% point of additional electrical efficiency compared to respective J420 B versions.

The J420 D/E genset, for example, delivers a robust concept with a compact footprint with a 0.6-metre reduction in length compared to previous Type 4 genset versions.

The CHP plant at Nova Pazova, will be fuelled by hydrogen generated via an electrolyzer which, in turn, is powered by a solar photovoltaic (PV) plant located near Cuprija.

The electrolyzer is used to produce green hydrogen for interim storage before the hydrogen is transported from Cuprija to Nova Pazova.

This achieved in the following process: water molecules (H2O) contain hydrogen (H). The H2 is separated from the O in a process called the electrolysis of water. Electrolysis is the technique used to produce hydrogen which consists of “breaking” the water molecules using an electric current in an electrolyzer in order to extract the dihydrogen H2. The electricity must itself be carbon-free in order to consider this hydrogen as green or renewable.

Most of the hydrogen will be produced during the summer in Serbia when the output produced by solar plants is high.

In times of low hydrogen supply, the CHP plant will run on natural gas, to ensure the continuous provision of energy. The Jenbacher team will work with its distributor, STI d.o.o., to implement, install and service the hydrogen CHP unit.

Combined Heat and Power Module (CHP Module) solutions like these allow customers to generate power and heat simultaneously at a very high total efficiencies, reaching 90% and even more.

Advanced design features

Jenbacher Type 4 engines have the same design, emissions control, and waste gas-to-energy capabilities as their Type 2 and Type 3 counterparts, plus high power density and outstanding efficiency in their power range.

The high-power turbocharger allows optimal operation at higher air intake temperature and altitude.

A four-valve cylinder heads f eatures enhanced swirl and channel geometry using advanced calculation and simulation methods, resulting in optimal cooling and combustion conditions. The Type 4’s connecting rod reduces bearing wear and is easy to maintain.

Combined Heat and Power Module (CHP Module) solutions incorporating Jenbacher Type 4 engines allow customers to generate power and heat simultaneously at a very high total efficiencies, reaching 90% and even more, says Innio.

Such CHP Modules can generate hot water or steam at various parameters and can be integrated with existing heat infrastructure.

Clients can select the option whch fits a project’s needs from among the various heat recovery schemes provided by Jenbacher.

The scope of supply can be extended further with various balance of plant options (BOP)offered by Jenbacher.

The right auxiliary equipment is of critical importance in ensuring that a power solution is economically feasible and provides a particular business with the most benefits in terms of reliability, availability and efficiency, says Innio.

Delivering carbon-free electricity when hydrogen is available Dr. Olaf Berlien, president and CEO of INNIO, commented on the Nova Pazovaproject:“Our H2-engines provide the flexibility and sustainability to meet PAN-LEDI’s pioneering requirements. INNIO’s technology will deliver carbon-free electricity when hydrogen is available, while maintaining continuity of power generation when hydrogen is scarce.”

Slobodan Vujovic, CEO PAN-LEDI d.o.o. concludes“Using hydrogen or natural gas to operate our combined heat and power plant is critical for our EV charging station strategy. INNIO’s Jenbacher CHP solution will provide our operation with the flexibility required for a sustainable EV mobility and use hydrogen at high CHP utilisation rates.” www.innio.com www.jenbacher.com
