Nikola Corp's CEO, Steve Girsky, shared his optimism regarding the company's competitive stance in the electric vehicle (EV) market, particularly in the face of rivals like Tesla Inc. The company's recent success can be attributed to its fuel cell trucks, which are proving to be more efficient than battery electric trucks in certain conditions. Girsky highlighted the limitations of battery electric trucks in cold weather and high altitudes, pointing out the advantages of Nikola's hydrogen fuel cell trucks. Despite facing initial setbacks with battery electric trucks, which were recalled due to fire incidents, Nikola has shifted its focus towards hydrogen fuel cell trucks, a move supported by the company's CFO, Tom Okray. This strategic decision has paid off, with Nikola reporting increased sales and production figures in the second quarter, surpassing analyst expectations. On the other hand, Tesla's CEO, Elon Musk, continues to express skepticism towards hydrogen as a viable energy source, favoring batteries. Despite differing opinions on fuel sources, Nikola's stock closed higher, reflecting positive market sentiment towards the company's growth trajectory.
