BE vs FCEL: How Bloom Energy and FuelCell Energy Compare (2026)
Short answer
BE (Bloom Energy) and FCEL (FuelCell Energy) are often compared because they share investment themes, but they are different businesses. Bloom Energy (BE) designs and manufactures solid-oxide fuel cell systems that generate electricity on-site for commercial and industrial customers. FuelCell Energy designs, builds, operates, and services stationary fuel-cell power platforms, most notably its carbonate fuel-cell technology, which generates electricity through an electrochemical reaction rather than combustion. Neither is universally better: pick by which thesis you are expressing and what you already own. This is descriptive, not a recommendation.
What does Bloom Energy (BE) do?
Bloom Energy (BE) designs and manufactures solid-oxide fuel cell systems that generate electricity on-site for commercial and industrial customers. Its flagship product, the Bloom Energy Server, converts natural gas, biogas, or hydrogen into electricity through an electrochemical process that is cleaner and more efficient than combustion, providing reliable, always-on power independent of the grid. Customers use Bloom's systems for resilient primary or backup power, to reduce emissions, and increasingly to power energy-intensive facilities like data centers that need large amounts of dependable electricity quickly, often faster than utilities can deliver new grid capacity. Bloom also develops solid-oxide electrolyzer technology to produce hydrogen, positioning it for a potential hydrogen economy. The company sells equipment and offers service and financing arrangements, building a base of long-term service revenue. The investment story centers on distributed, resilient clean power and surging electricity demand from AI data centers. Founded in 2001 and headquartered in San Jose, California, Bloom Energy is a higher-risk clean-energy growth company working toward sustained profitability.
What does FuelCell Energy (FCEL) do?
FuelCell Energy designs, builds, operates, and services stationary fuel-cell power platforms, most notably its carbonate fuel-cell technology, which generates electricity through an electrochemical reaction rather than combustion. The company earns money four ways, and its $1.14 billion backlog (as of April 30, 2026) shows the mix: a small product segment (~$36 million) selling power plants outright, a service segment (~$155 million) maintaining customer-owned plants under long-term agreements, a large generation segment (~$928 million) where FuelCell owns projects and sells the power under long-term purchase agreements averaging about 15 years, and a small advanced-technology segment (~$15 million) that includes its ExxonMobil carbon-capture work. The generation backlog is the recurring, visible piece; product revenue is lumpy and depends on winning new orders. In fiscal Q2 2026 (quarter ended April 30, 2026) the company reported revenue of ~$35.6 million, down about 5% year over year, a net loss of ~$77.6 million, and adjusted EBITDA of ~$(17.1) million, while holding ~$440.9 million in cash and restricted cash supported partly by ongoing share sales.
BE vs FCEL: how do they differ?
Both fit overlapping themes, but they are not interchangeable. Bloom Energy is best understood through its own drivers, and FuelCell Energy through its. The useful comparison is which set of drivers and risks you want exposure to.
- BE drivers: Data center power demand; Resilient distributed power.
- FCEL drivers: AI data-center power pivot; Long-term generation backlog.
BE vs FCEL: how they make money and what they cost
BE. Bloom Energy is a growth-stage clean-energy company, so it is valued on revenue growth, gross-margin improvement, and the path to sustained profitability rather than current earnings. The valuation embeds optimism about data center demand and distributed power adoption, making the stock highly sensitive to order momentum, clean-energy sentiment, interest rates, and incentive policy.
FCEL. Figures are approximate and tied to the asOf date; verify live numbers before acting. FuelCell has no meaningful earnings, so a traditional price-to-earnings ratio does not apply; the market values it on backlog, pipeline, and the data-center narrative rather than current profit. That makes the stock highly sensitive to deal headlines and sentiment, which is why the 52-week range spans from under $4 to nearly $38, and why the figures matter most as a gauge of how much optimism is priced in.
Headline figures (approximate, early 2026): BE shows revenue (ttm) ~$1.3-1.6 billion, operating margin Thin to negative (approaching profitability), gross margin Improving, ~20-30% range; FCEL shows revenue (fiscal q2 2026 quarter) ~$35.6 million, down ~5% year over year, net loss (fiscal q2 2026) ~$77.6 million, or ~$(1.45) per share, adjusted ebitda (fiscal q2 2026) ~$(17.1) million. A cheaper-looking multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is actually compounding.
Which fits which kind of investor
Both share a theme, but they suit different temperaments. Bloom Energy's case leans on data center power demand, and FuelCell Energy's on ai data-center power pivot. A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Bloom has a long history of losses and has struggled to reach consistent profitability, relying on growth and financing to fund operations. For FCEL, the central risk is that FuelCell is still deeply unprofitable and burns cash: fiscal Q2 2026 brought a ~$77.6 million net loss on ~$35.6 million of revenue, and revenue actually fell about 5% year over year.
BE or FCEL: which should you pick?
The bottom line: BE vs FCEL
BE and FCEL are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.

FAQ
What is the difference between BE and FCEL?
+
Bloom Energy (BE) designs and manufactures solid-oxide fuel cell systems that generate electricity on-site for commercial and industrial customers. FuelCell Energy designs, builds, operates, and services stationary fuel-cell power platforms, most notably its carbonate fuel-cell technology, which generates electricity through an electrochemical reaction rather than combustion. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is BE or FCEL the better stock?
+
Walnut is informational, not investment advice. Neither is universally better; BE and FCEL suit different views and risk levels. Compare what each does, how they make money, and the risks, then decide which fits your thesis and what you already own.
Should you own both BE and FCEL?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both before you add the second.
What are the risks of BE vs FCEL?
+
BE: Bloom has a long history of losses and has struggled to reach consistent profitability, relying on growth and financing to fund operations. The economics of its systems depend on natural gas prices, electricity prices, and government incentives, which can change. Its fuel cells most often run on natural gas, so the clean-energy positioning is partial and exposed to shifting policy and emissions standards. The company faces competition from grid power, gas turbines, batteries, and other distributed-generation technologies, and the data center opportunity, while large, is contested. Bloom carries debt and has had cash-flow pressures, and the stock is highly volatile, sensitive to clean-energy sentiment, interest rates, incentive policy, and order timing. FCEL: The central risk is that FuelCell is still deeply unprofitable and burns cash: fiscal Q2 2026 brought a ~$77.6 million net loss on ~$35.6 million of revenue, and revenue actually fell about 5% year over year. Much of the exciting data-center pipeline is non-binding, so it may not convert into firm, funded orders on the timeline the stock has priced in. The company has repeatedly raised money by selling shares, which dilutes existing holders, and it executed a 1-for-30 reverse split in late 2024 after its share price collapsed. Its backlog declined about 10% year over year as revenue was recognized without enough new bookings to replace it. The stock is extremely volatile (a 52-week range from under $4 to near $38), it faces well-funded competitors, and clean-energy policy shifts and subsidy changes can swing demand for its projects.
