Nikola, the electric and hydrogen-fueled truck maker, experienced a significant surge in its stock price following the disclosure of 72 hydrogen truck deliveries in the second quarter, surpassing its own projections. The deliveries of HYLA Class 8 hydrogen-powered trucks to wholesalers, which included a new customer in Walmart Canada, nearly doubled the previous quarter's numbers. Nikola's CEO highlighted the company's progress in dominating the zero-emissions Class 8 truck segment in North America. The article discusses the advantages of hydrogen as a zero-emission fuel, particularly in addressing the weight concerns present in electrifying long-haul trucks. While acknowledging the energy required to produce hydrogen, Nikola remains optimistic about the potential cost reductions as more hydrogen trucks enter the market and infrastructure improves. Despite the positive news, caution is advised for investors due to Nikola's financial challenges, including significant cash burn and the need for profitability. Additionally, the article offers insights into the retail price of hydrogen, currently at $32 per kg, and how Nikola anticipates this cost to decrease over time. The stock surge is viewed as partially driven by short-covering and the company's efforts to recover from past issues. Investors are encouraged to wait for Nikola to demonstrate sustainable profitability before considering investments in the company.
