According to CoinMeta, after years of testing, hydrogen energy stocks provided two different reasons for optimism in August 2026: one company is gradually approaching profitability after a severe restructuring, while another has profited from the wave of artificial intelligence (AI). Plug Power (Nasdaq: PLUG) and Bloom Energy (New York Stock Exchange: BE) are worth watching. The stock price of Plug Power has fallen by more than 90% from its historical high, but it has risen by 40% in the past 12 months. In the second quarter of 2026, Plug had an adjusted loss of only $0.07 per share, exceeding expectations, with revenue reaching $178.3 million and a gross margin close to break-even. Bloom Energy's solid oxide fuel cells have become one of the most popular power sources for AI data centers, with operating revenue in the second quarter of 2026 increasing by 680% year-on-year, exceeding $1 billion. Management stated that this is not accidental and has raised their performance expectations.
