The surge in Plug Power's shares was driven by investors' optimism regarding a new market opportunity rather than direct news from the hydrogen power company itself. The Federal Energy Regulatory Commission's rejection of a power increase request from a nuclear plant to supply an Amazon data center led to a 19.9% increase in Plug Power's shares. Talen Energy, the operator of the nuclear plant, aimed to enhance power supply to an Amazon Web Services (AWS) data center, potentially creating a market for Plug Power's hydrogen electrolyzers. Plug Power is actively developing its hydrogen ecosystem to offer clean power solutions, such as using electrolyzers to produce green hydrogen from renewable sources, which could be utilized to power data centers. The company recently announced a significant agreement with an Australian company to supply 3,000 MW of electrolyzer capacity for ammonia production. While data center operators have considered nuclear power and modular reactors for energy supply, the adoption of Plug Power's electrolyzers may not be immediate due to the associated costs and the company's lack of profitability. Investors are advised to approach stock investments cautiously and not solely rely on the potential new business from data centers as a catalyst for immediate gains.
