Overview

Dynelectro has delivered its inaugural 250kW Dynamic Electrolyzer Unit (DEU) to Syntholene Energy’s power-to-sustainable aviation fuel (e-SAF) demonstration project in Húsavík, Iceland. This deployment aims to gather vital operational data for the optimization and scale-up of green hydrogen production. Notably, Syntholene Energy’s geothermal-integrated Solid Oxide Electrolysis Cell (SOEC) facility was completed six months early, fast-tracking the path to viable e-SAF.

In Depth

Background

The aviation industry faces immense challenges in decarbonization, making the rapid adoption of Sustainable Aviation Fuels (SAF) an urgent global priority. Among these, e-SAF, synthesized from green hydrogen and captured CO2, is emerging as a highly promising pathway to substantially reduce emissions. Leveraging its abundant renewable energy resources, particularly geothermal power, Iceland is uniquely positioned to become a leading hub for green hydrogen and e-SAF production. The collaborative project between Dynelectro and Syntholene Energy serves as a critical, tangible demonstration, aiming to prove the commercial viability and accelerate the realization of e-SAF production at scale.

Key Findings

Dynelectro has successfully delivered its inaugural 250kW Dynamic Electrolyzer Unit (DEU) to Syntholene Energy’s e-SAF demonstration project in Húsavík, Iceland. This pivotal deployment, coupled with Syntholene Energy’s ahead-of-schedule completion of its geothermal-integrated Solid Oxide Electrolysis Cell (SOEC) facility, marks a significant acceleration in the project’s timeline and the overall feasibility of e-SAF production.

The 250kW DEU is specifically engineered for optimal integration with variable renewable energy sources, such as Iceland’s robust geothermal power. Dynamic electrolyzers are crucial for maximizing renewable electricity utilization by rapidly adjusting to power fluctuations, thereby ensuring stable and cost-effective green hydrogen production. Syntholene Energy’s SOEC technology further enhances efficiency by operating at elevated temperatures, intelligently leveraging waste heat from geothermal processes for improved overall energy utilization. These advanced electrolysis technologies are foundational for creating a sustainable and economical hydrogen supply, which, when combined with captured CO2, forms the basis of e-SAF.

The combined operation of Dynelectro’s DEU and Syntholene Energy’s SOEC facility is poised to generate invaluable operational data and insights, critical for optimizing the efficiency and economics of future e-SAF manufacturing. This initial data will inform the design and scaling of large-scale commercial plants, pushing the aviation industry closer to its decarbonization targets. A successful demonstration will not only solidify Iceland’s emerging leadership in sustainable fuel production but also present a tangible investment opportunity in the rapidly expanding e-SAF market. This integrated technological approach holds immense potential as a vital pathway for the global aviation fleet to achieve its ambitious net-zero emissions goals.
