Hydrogen systems are more advantageous than battery storage: Study presents the potential in mobility and logistics ^↺

For a successful transition to sustainable energy, Bremerhaven University of Applied Sciences researchers have spent two years exploring hydrogen technologies as an alternative to fossil fuels. As reducing CO₂ emissions is crucial to meet climate protection targets, the hydrogen economy may play a significant part in achieving a greener energy supply.

The technical feasibility of employing hydrogen as a molecular energy storage medium is ideal for decentralized production, storage, and usage. Nonetheless, its marketability and competitiveness require further testing, as well as establishing an infrastructure for this energy source. The "Hydrogen - green gas for Bremerhaven" project, financed by the ERDF, is examining possible applications for energy supply, vehicle propulsion, logistics usage (such as forklift trucks), and e-fuel experiments.

Even a hydrogen oven has been developed. The "Microgrids - self-sufficient units" study explored the possibility of powering an entire industrial area solely with renewable energy. The "IWAS - Lune Delta" project is examining the economic viability of adopting hydrogen as an alternative for industrial corporations.

From an environmental perspective, the hydrogen storage system is superior over the entire lifespan in comparison to battery storage. Additionally, expanding the storage capacity of hydrogen systems proves to be easier. However, battery systems possess more maturity and for smaller storage systems, they are more cost-effective than hydrogen systems.

Hydrogen in logistics and mobility

As transportation plays a key role in a sustainable economy, the "Hydrogen in Logistics and Mobility" sub-study conducted research on the latest trends in the mobility sector. The instance of forklift trucks highlights that despite being equipped with battery storage, their performance deteriorates as the battery level depletes and charging times are lengthy. Conversely, hydrogen can be refuelled rapidly and without generating CO₂ emissions.

Acceptance is crucial for use in companies as employee feedback was immensely positive. The hydrogen-powered lorry showed outstanding work performance and was comparable to the battery-operated lorries used. Furthermore, the truck's possible operating time was sufficient for the drivers' daily working hours.

While companies are receptive to adopting new technology, they remain hesitant to invest. Therefore, Prof Fichter suggests implementing technological advancements in incremental stages and ongoing processes. The project was financed by the state of Bremen and the European Regional Development Fund (ERDF) for approximately 20 million euros.
