Green Hydrogen and Electrons for Carbon-based Chemistry
Carbon-based chemicals are everywhere: in our homes, in our vehicles and in our workplaces. However, the chemical industry currently heavily relies on fossil resources, producing large CO2 emissions. As the demand for carbon-based materials continues to rise, new sustainable carbon sources are essential. HyCARB addresses this challenge by developing technologies that reuse CO₂ as a renewable carbon source, powered by green hydrogen and renewable electricity. This approach reduces emissions, increases circularity and supports the broader Dutch and European climate goals.
HyCARB is a national innovation programme that brings together universities, research institutes and industry partners to develop new technologies for converting captured CO₂, green hydrogen and renewable electricity into sustainable fuels and chemicals. With more than 100 researchers and 45 partner organisations, HyCARB strengthens the Netherlands’ position as a leader in circular carbon chemistry and supports the transition to a climate neutral chemical industry.
HyCARB focuses on a full chain of CO₂‑conversion technologies. This includes catalytic processes that turn CO₂ and hydrogen into fuels and essential chemical feedstocks, electrochemical systems that convert CO₂ using electricity, and electrified reactors designed to replace fossil‑based heating. All technologies are designed to work with intermittent renewable energy, ensuring compatibility with future energy systems.
A major part of the project is dedicated to system integration. HyCARB develops digital twins and modelling tools to understand how these technologies behave under real‑world conditions, and it builds pilot‑scale demonstrations to validate performance outside the laboratory. This includes a containerised e‑methane unit that operates directly on fluctuating solar and wind power.
Entrance plays a central role in the fourth research line (task D), bringing HyCARB technologies into practice. At our living lab, researchers test CO₂‑conversion systems under realistic energy conditions, using data from weather forecasts, energy markets and on‑site renewable production. Entrance also leads the Life Cycle Assessment (LCA) for the e‑methane pilot and contributes to the Techno‑Economic Analysis (TEA), offering partners clear insight into the environmental impact and cost competitiveness of each technology.
By combining pilot data, predictive models and sustainability analysis, Entrance helps the consortium determine which CO₂‑conversion pathways are most promising for industrial scaling.
By the end of the four-year project, HyCARB will have delivered a new generation of sustainable CO₂‑conversion technologies ready for pilot‑scale deployment. This includes advanced catalysts, electrolysers and electrified reactors that retain high performance even when powered by variable renewable energy. The project will also produce fully validated digital twins and detailed LCA/TEA studies, providing industry and policymakers with reliable guidance for future investments.
Beyond technical advances, HyCARB strengthens the Dutch innovation ecosystem. The project stimulates new business opportunities in catalyst development, electrochemical systems, CO₂‑capture materials and electrification equipment, while training a new generation of engineers and researchers in circular carbon technologies. Together, these outcomes support economic growth, improve sustainability and position the Netherlands as a European frontrunner in green chemistry and hydrogen‑powered industry.
HyCARB is a GroenvermogenNL project. The grant is provided by NWO.
