The story

The company was founded as Energy Research Corporation (ERC) in 1969 by chemical engineers Bernard Baker and Martin Klein. From the 1970s to 1990s, with sponsorship from U.S. military and other utility companies, the company extended to low-temperature fuel cell area and high-temperature carbonate fuel systems.

It completed its IPO in 1992 and was renamed as FuelCell Energy, Inc. It spun off its battery division, Evercel, in 1999. FuelCell Energy began expanding globally in 2007 through a partnership with POSCO Energy, targeting markets in Asia, particularly South Korea, but the company announced the termination of the partnership in 2020.

In 2012, the company's European facility was established with German-based FuelCell Energy Solutions, GmbH. In the same year, it completed a joint venture with Fraunhofer IKTS and acquired Versa Power Systems, Inc.

Beginning in 2012, FuelCell entered into a partnership with ExxonMobil to remove carbon dioxide from the exhaust of Exxon's power plants for carbon capture and sequestration (CCS). In 2019, the two companies renewed their joint-development agreement.

In 2017 FuelCell entered an agreement with Toyota to develop a 2.25 MW facility at Long Beach, California. Also in 2017, FuelCell was tapped by the Office of Naval Research to provide assistance on the Large Displacement Unmanned Undersea Vehicle (LDUUV) program.

In 2018, FuelCell Energy earned a $1.5 million research grant from the U.S. Department of Energy (DOE) to develop the company's fuel cell technology to aid the nuclear industry by converting excess power back into hydrogen. That same year, FuelCell began the construction of two plants in Hartford and New Britain as part of a clean energy procurement process for the Connecticut Department of Energy and Environmental Protection (DEEP).

In November 2018, FuelCell acquired a 14.9-MW fuel cell project in Bridgeport, Connecticut from Dominion Energy for $37 million. FuelCell had developed, built and been operating the plant since 2013. The plant is powered by five FuelCell stationary fuel cell power plants and an organic rankine turbine that converts heat from the fuel cells into additional electricity, which is sold to Connecticut Light & Power.

In 2019, FuelCell entered an agreement with Drax Power Station in the UK to study the use of the company's carbonate fuel cells to capture carbon dioxide emissions from Drax's biomass boilers. In August 2019, Jason Few was named FuelCell's new president and CEO.

In May 2021, the company obtained $8 million from the DOE for solid oxide fuel cell (SOFC) technology development.

In June 2021, FuelCell completed construction on a project with the city of San Bernardino Municipal Water Department (SBMWD) where a fuel cell treats anaerobic digester gas to produce electricity and thermal energy.

Products and brands

The company today has fuel cell projects that run on natural gas and biogas. The cells can produce hydrogen in addition to power and thermal energy. Additionally, the company is developing fuel cell-based carbon capture, long-duration energy storage and solid-oxide based electrolysis.

FuelCell's proprietary technology uses carbonate fuel cells to capture and concentrate carbon dioxide from large industrial sources. Combustion exhaust is directed to the fuel cell, which produces power while capturing and concentrating carbon dioxide for permanent storage.

Risk factors and legal proceedings

The risks FuelCell Energy names in Item 1A of its 10-K filed Dec 18, 2025: 43 risks under these headings, as written.18

  • Risks Related to Our Business, Industry and Supply Chain
  • We have incurred losses and anticipate continued losses and negative cash flows.
  • Our cost reduction strategy for manufacturing may not succeed or may be significantly delayed, which may result in our inability to deliver improved margins.
  • We have debt and finance obligations outstanding and may incur additional debt in the future, which may adversely affect our financial condition and future financial results.
  • We rely on project financing for our generation operating portfolio, which includes debt and tax equity financing arrangements, to realize the benefits provided by investment tax credits and accelerated tax depreciation. In the event that interest rates rise or there are changes in tax policy, our financial results could be harmed.
  • Unanticipated increases or decreases in business growth have resulted and may continue to result in adverse consequences to our financial condition and business strategy.
  • Our workforce reduction may cause unintended consequences and our results of operations may be harmed.
  • If our intangible assets and long-lived assets (including project assets) become impaired in the future, we may again be required to record a significant charge to operations.
  • Our Advanced Technologies contracts are subject to the risk of termination by the contracting party and we may not realize the full amounts allocated under some contracts due to the lack of Congressional appropriations or early termination.
  • Utility companies may resist the adoption of distributed generation and could impose customer fees or interconnection requirements on our customers that could make our products less desirable.
  • Utility companies commonly charge fees to larger, industrial customers for disconnecting from the electric grid or for having the capacity to use power from the electric grid for back up purposes. These fees could increase the cost to our customers of using our SureSource products and could make our products less desirable, thereby harming our business prospects, results of operations and financial condition.
  • We depend on third party suppliers for the development and timely supply of key raw materials and components for our products.
The other 32 risks
  • An increase in energy costs may materially adversely affect our business, financial condition, and results of operations.
  • Failure to meet Environmental, Social, and Governance (“ESG”) expectations or standards or to achieve our ESG goals could adversely affect our business, results of operations, financial condition, and stock price.
  • Risks Related to Sales of our Products
  • We derive significant revenue from contracts awarded through competitive bidding processes involving substantial costs and risks. Our contracted projects may not convert to revenue, and our project awards and sales pipeline may not convert to contracts, which may have a material adverse effect on our revenue and cash flows.
  • We have signed product sales contracts, EPCs, PPAs and long-term service agreements with customers subject to contractual, technology, operating, commodity (i.e. natural gas) and fuel pricing risks as well as market conditions that may negatively affect our operating results.
  • We extend product warranties for our products, which products are complex and could contain defects and may not operate at expected performance levels, which could impact sales and market adoption of our products, affect our operating results or result in claims against us.
  • We currently face and will continue to face significant competition, including from products using other energy sources that may be lower priced or have preferred environmental characteristics.
  • Our plans are dependent on market acceptance of our products.
  • Our development timeline for bringing our solid oxide electrolysis technology to market has shifted as a result of delays in adoption of clean energy technologies generally and implementation of our recent global restructuring actions, which have re-focused our business on our core carbonate technologies. In addition, our timeline for bringing our carbon capture technology to market will be subject to conditions outside of our control.
  • Our products use inherently dangerous, flammable fuels, operate at high temperatures and use corrosive carbonate material, each of which could subject our business to product liability claims.
  • Risks Related to Privacy, Data Protection and Cybersecurity
  • Our reliance on information technology continues to grow, and disruptions, failures, or security breaches could materially impact both our operations and the operations of our power plant platforms. Furthermore, the rise in information technology security threats and increasingly sophisticated cybercrime presents ongoing risks to our systems, networks, products, and services.
  • Tax, Accounting, Compliance and Regulatory Risks
  • We are required to maintain effective internal control over financial reporting. In a prior fiscal year, our management identified a material weakness in our internal control over financial reporting. If other control deficiencies are identified in the future, we may not be able to report our financial results accurately, prevent fraud or file our periodic reports in a timely manner, which may adversely affect investor confidence in our Company and, as a result, the value of our common stock.
  • Our results of operations could vary as a result of changes to our accounting policies or the methods, estimates and judgments we use in applying our accounting policies.
  • We may be affected by environmental and other governmental regulation.
  • A negative government audit could result in an adverse adjustment of our revenue and costs and could result in civil and criminal penalties.
  • Exports of certain of our products are subject to various export control regulations and may require a license or permission from the U.S. Department of State, the U.S. Department of Energy or other agencies.
  • Our business currently benefits from the availability of rebates, tax credits and other financial programs and incentives, and changes to such benefits could cause our revenue to decline and harm our financial results.
  • Risks Related to Our Need for Additional Capital
  • We will need to raise additional capital, and such capital may not be available on acceptable terms, if at all. If we do raise additional capital utilizing equity, existing stockholders will suffer dilution. If we do not raise additional capital, our business could fail or be materially and adversely affected.
  • Risks Related to our Intellectual Property and Technology Licenses
  • We depend on our intellectual property, and our failure to protect that intellectual property could adversely affect our future growth and success.
  • The U.S. government has certain rights relating to our intellectual property, including the right to restrict or take title to certain patents.
  • Risks Related to Our Common and Preferred Stock
  • Our stock price has been and could remain volatile.
  • Our failure to meet the continued listing standards of The Nasdaq Global Market could result in a delisting of our common stock, which could limit investors’ ability to make transactions in our common stock and subject us to additional trading restrictions.
  • Future sales of substantial amounts of our common stock could affect the market price of our common stock.
  • Provisions of Delaware and Connecticut law and of our certificate of incorporation and by-laws may make a takeover more difficult.
  • Our By-laws provide that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a judicial forum deemed favorable by the stockholder for disputes with us or our directors, officers or employees.
  • The rights of our Series B Preferred Stock could negatively impact our cash flows and dilute the ownership interest of our stockholders.
  • The Series B Preferred Stock ranks senior to our common stock with respect to payments upon liquidation, dividends, and distributions.
  • General Risk Factors
  • Litigation could expose us to significant costs and adversely affect our business, financial condition, and results of operations.
  • Financial markets worldwide have experienced heightened volatility and instability which may have a material adverse impact on our Company, our customers and our suppliers.
  • Weakness in the economy and other conditions affecting the financial stability of our customers could negatively impact future sales of our products and our results of operations.
  • Our results of operations could be adversely affected by economic and political conditions globally and the effects of these conditions on our customers’ businesses and levels of business activity.
  • Our future success will depend on our ability to attract and retain qualified management, technical, and other personnel.
  • We are subject to risks inherent in international operations.

Legal proceedings

From time to time, the Company is involved in legal proceedings, including, but not limited to, regulatory proceedings, claims, mediations, arbitrations and litigation, arising out of the ordinary course of its business (“Legal Proceedings”). Although the Company cannot assure the outcome of such Legal Proceedings, management presently believes that the result of such Legal Proceedings, either individually, or in the aggregate, will not have a material adverse effect on the Company’s consolidated financial statements, and no material amounts have been accrued in the Company’s consolidated financial statements with respect to these matters.
