Investors weighing fuel cell stocks in 2026 face a compelling choice between two companies with very different financial profiles and growth strategies.
Bloom Energy Corp (NYSE: BE) focuses on solid oxide fuel cell systems for on-site power generation, primarily targeting data centers and industrial customers across the United States and South Korea.
Plug Power Inc (NASDAQ: PLUG) takes a broader approach, building an end-to-end hydrogen ecosystem that covers production, storage, and fuel cells for material handling and heavy-duty transport.
Bloom Energy posted revenue exceeding $2 billion in FY 2025, representing approximately 37% growth over the prior year, though the company still reported a net loss of roughly $88.4 million.
The company achieved positive free cash flow of roughly $57.2 million for the year, a milestone that signals meaningful operational progress for a business long associated with losses.
Key partners for Bloom include American Electric Power Co (NASDAQ: AEP), which signed a strategic agreement for fuel cells targeting artificial intelligence applications, and Brookfield Infrastructure Partners LP (NYSE: BIP).
Plug Power generated $709.9 million in revenue during FY 2025, reflecting nearly 13% growth, but reported a net loss of approximately $1.6 billion, around $500 million narrower than its 2024 loss.
Walmart Inc (NASDAQ: WMT) remains one of Plug Power’s primary revenue contributors, underscoring the company’s deep penetration into the material handling and logistics sectors.
Plug Power is also partnered with Orica for the Hunter Valley Hydrogen Hub in Australia, reflecting its ambition to scale electrolyzer technology across five continents.
From a valuation standpoint, Bloom Energy carries a forward P/E of approximately 80x and a price-to-sales ratio of 19, while Plug Power trades at a P/S ratio of just 3.6x with no meaningful forward P/E due to negative earnings estimates.
Wall Street analysts expect Bloom Energy’s revenue to leap approximately 85% to $3.75 billion in fiscal 2026, with projections pointing to a swing to net income of around $440 million.
Plug Power’s fiscal 2026 revenue consensus sits at roughly $814 million, representing nearly 15% growth, with the net loss expected to narrow to approximately $500 million.
Bloom Energy faces risks around market adoption, supply chains for rare materials, and potential changes to government tax credits or interconnection tariffs that could dampen demand for its systems.
Plug Power faces significant liquidity risks stemming from years of operational losses and is currently defending itself against securities class action lawsuits regarding its past disclosures.
Plug Power also contends with competition from large industrial players including Alphabet Inc (NASDAQ: GOOG), Amazon.com Inc (NASDAQ: AMZN), Cummins Inc (NYSE: CMI), and Ballard Power Systems (NASDAQ: BLDP).
Despite Bloom Energy’s impressive near-term growth trajectory, the argument for a deeper competitive moat is harder to make, as building a generator and connecting it to a data center is a relatively replicable business model.
Major Plug Power customers Amazon and Walmart are approaching replacement phases in their product cycles, which could generate substantial recurring revenue for the company in coming years.
The European Union’s mandate requiring 42% of industrial hydrogen to be renewable by 2030 further strengthens the long-term demand backdrop for Plug Power’s green hydrogen platform.
Considering its lower price-to-sales ratio, long-term ecosystem positioning, and improving loss trajectory, Plug Power represents the more compelling fuel cell investment heading further into 2026.
