Renault Group, a prominent player in the electric vehicle market, recognizes the importance of advancing electric cars to decarbonize mobility. While electric vehicles have significantly evolved in terms of battery energy density and efficiency, challenges such as range and refueling times still persist compared to traditional internal combustion engine vehicles. In response to this, Renault is exploring dual-energy hydrogen-battery electric powertrains as a solution to enhance the range and versatility of electric cars. The incorporation of hydrogen as an energy source alongside batteries offers a promising synergy. Hydrogen, known for its abundance, green production methods, and quick refueling capabilities, presents a viable option for powering electric motors. Renault's research into fuel cells, which utilize both batteries and hydrogen to extend vehicle range, demonstrates the potential of this technology. Renault is actively developing dual-energy battery-hydrogen technology for passenger cars. This innovative approach ensures a balanced power delivery from both energy sources, enabling long-distance travel without compromising performance. The Renault Emblème demo car, unveiled at the 2024 Paris Motor Show, exemplifies this technology by combining a rechargeable battery with a hydrogen fuel cell. With this configuration, the Emblème can cover up to 1,000 km in a single journey, requiring only brief hydrogen refueling stops. By leveraging the advantages of both hydrogen and batteries, Renault is spearheading the advancement of long-range electric mobility. The dual-energy approach not only enhances vehicle range but also contributes to a more sustainable and efficient transportation ecosystem.
