What Dynelectro does

Dynelectro ApS is a Danish solid oxide electrolyser (SOEC) original equipment manufacturer founded in 2018 by Søren Højgaard Jensen and headquartered in Viby Sjælland, Denmark, with engineering operations in Copenhagen. The company designs and sells modular, MW-scale reversible Dynamic Electrolyser Units (DEUs) in 250 kW, 1 MW, 5 MW, and 20 MW configurations for green hydrogen production, energy storage, and reversible power generation. Its core technology centres on a patented AC:DC operating method that periodically relieves electrical stress through voltage reversal, extending SOEC stack lifetime from the industry average of approximately two years to 7–10 years while delivering up to 90% electrical efficiency and 27 kg of hydrogen per MWh(e), with stack degradation measured below 0.1% per 1,000 hours across 25,000 hours of testing.

The product portfolio is underpinned by additional proprietary assets, including the ReScale manufacturing method for SOEC steam electrodes and electrolytes, and an AI-supported Virtual Power Plant layer for electricity price forecasting, grid balancing, and predictive degradation modelling. Dynelectro monetises through direct enterprise sales of hardware systems supplemented by project engineering, integration, and commissioning services, with systems quoted on a project basis under multi-year contracts and lead times of 12 months for sub-1 MW units and 24 months for larger systems. Go-to-market is content-led at the top of the funnel via the corporate newsroom, LinkedIn, and industry conferences (European Hydrogen Week, SOFC-XIX), converting at the bottom of the funnel through an Expression of Interest / Request for Quote process.

Target customer segments include industrial decarbonisation (chemicals, steel, refineries), sustainable mobility and e-fuels producers (eSAF, e-methanol, ammonia), energy storage and grid services, the agricultural sector, and biogas/e-methane operators. Named deployments and partnerships include Syntholene Energy (250 kW DEU for Iceland eSAF demonstration, Húsavík), Rainbow Colors (1 MW SOEC system at Dutch tulip nursery, Andijk), a biogas plant in the DynEfuel project (250 kW for e-methane), a Power-to-X collaboration with Siemens Gamesa, technology supply from SolydEra and assembly support from Eltronic PtX, and participation in EU-funded consortia HySPRINT, ViPES2X, and R2P2X. To date the company has secured approximately €20 million in cumulative innovation funding, grants, and equity, led by an €11 million round in July 2024 led by Denmark's EIFO with participation from Shell, the European Innovation Council, Yara Growth Ventures, PSV Hafnium, Footprint Fund, and Vsquared Ventures.

Core offering

Dynelectro designs, manufactures, and sells MW-scale reversible solid oxide electrolyser (SOEC) systems branded as Dynamic Electrolyser Units (DEUs) in 250 kW, 1 MW, 5 MW, and 20 MW configurations. The DEUs use Dynelectro's patented AC:DC operation method to convert renewable electricity into green hydrogen, store energy, and generate power for industrial customers in sectors such as chemicals, steel, refineries, sustainable aviation fuel (eSAF), e-methanol, ammonia, biogas upgrading, and agricultural energy applications. The company also provides project engineering, system integration, and commissioning services for deploying DEUs at customer sites.

Product overview

Dynelectro is a Danish solid oxide electrolyser OEM offering a modular product line of Dynamic Electrolyser Units (DEUs) ranging from 250 kW to 20 MW capacity. The product portfolio includes four core systems: the 250 kW DEU for validation units, the 1 MW DEU for commercial deployment, the 5 MW DEU for larger industrial applications, and the 20 MW DEU for multi-MW industrial installations. All units are built on proprietary reversible solid oxide electrolysis (SOEC/SOFC) technology with the company's patented AC:DC methodology, enabling dynamic operation without traditional trade-offs between flexibility, efficiency, and stack lifetime. The systems deliver up to 90% electrical efficiency and support hydrogen production, energy storage, and power generation within a single platform for industrial decarbonisation and renewable energy integration.
