Fortum is pushing its district heating portfolio toward a lower-carbon future with the new Beyond Hydro combined heat and power (CHP) plant concept in Espoo, designed to run on natural gas today and be converted to hydrogen or other clean gases over time. The project underpins the company’s goal of phasing out coal-based heat in the Helsinki region while maintaining stable heat and power for tens of thousands of customers. Fortum’s own documentation describes Beyond Hydro as a flexible, hydrogen-ready gas CHP solution that can complement renewable electricity and eventually use clean fuels in place of fossil gas. Fortum’s announcement of the Beyond Hydro concept outlines the main design parameters and its role in the Espoo Clean Heat transition.

Hydrogen-ready CHP for a coal-free Espoo

The Beyond Hydro plant is part of Fortum’s Espoo Clean Heat program, a multi-year initiative to replace coal-based district heating with a mix of electric boilers, heat pumps, bioenergy and gas-fired capacity that can move to hydrogen and renewable fuels as they become available. Fortum has said that the CHP concept is being engineered to start on natural gas and later switch to low-carbon gases, giving the company a way to support security of supply today while aligning with tightening climate targets in Finland and the European Union. According to the company’s project description, the hydrogen-ready design focuses on high-efficiency turbines, modern flue-gas treatment and integration with the existing district heating network in the Espoo region, which currently serves hundreds of thousands of people and businesses.

Technically, the Beyond Hydro CHP configuration combines gas turbines, heat recovery and district heating interfaces so that the plant can produce both electricity and hot water with a high overall efficiency compared with separate generation. Fortum notes that the concept is being developed with a clear path to burn hydrogen-rich fuels in the future, a shift that would sharply lower direct combustion emissions once sufficient low-carbon hydrogen is available at competitive prices. The plant is intended to support a portfolio of assets in Espoo that already includes large heat pumps capturing energy from wastewater and seawater, industrial-size electric boilers, and smaller backup units, allowing Fortum to dispatch the most suitable asset depending on weather, power prices and demand patterns. In that setup, a flexible CHP unit that can eventually run on hydrogen functions as a balancing element alongside fully renewable assets.

From a customer perspective, the expansion of low-carbon heat in Espoo aims to reduce the climate footprint of residential and commercial buildings that rely on district heating while keeping service continuity during Finland’s long and cold winters. Fortum has framed Beyond Hydro as a way to support both Finland’s national climate targets and the company’s own ambition to align its power and heat portfolio with European decarbonization pathways, positioning the hydrogen-ready CHP as a bridge technology that can evolve as the broader hydrogen economy and gas infrastructure mature. Policymakers and industrial customers have shown growing interest in solutions that can initially reduce emissions with high-efficiency gas and then move to renewable gases, and Fortum’s concept responds directly to that demand.

The Beyond Hydro concept also sits against a backdrop of credit-rating agencies closely tracking Fortum’s investment plans and risk profile after the divestment of its German-based Uniper operations and a refocus on Nordic power and heat. Fitch Ratings, for example, recently affirmed Fortum’s long-term issuer default rating at BBB+ with a stable outlook, citing the company’s strong Nordic hydro and nuclear base as well as its relatively conservative balance sheet while also noting the execution risk around new investments and potential exposure to power price volatility. The rating report highlights that Fortum’s strategy now revolves around low-carbon generation in the Nordics and customer-oriented heat and power solutions, a context in which a hydrogen-ready CHP plant in Espoo fits as part of a more flexible, less carbon-intensive portfolio. Fitch’s June 2026 rating commentary on Fortum discusses how planned capital expenditure and asset mix inform the current rating stance.

Strategically, Fortum has called Espoo one of its key test beds for transforming district heating, complementing its established hydro and nuclear assets that dominate earnings and cash flow. The company argues that the hydrogen-ready CHP concept offers an option value on future fuel choices: it can secure heat and power today using natural gas while keeping a technical route open to hydrogen or other renewable gases once regulatory frameworks, carbon pricing and hydrogen infrastructure support a full switch. For investors, the project illustrates how Fortum is trying to maintain a balance between climate commitments, customer reliability and capital discipline at a time when energy systems across Europe are being reshaped by decarbonization and security-of-supply concerns. Fortum is listed on Nasdaq Helsinki, and its shares (ISIN FI0009007132) most recently traded on the Helsinki Stock Exchange, where live quote data show the utility remains closely tied to Nordic power price expectations and regulatory developments.
