HIPOLE Jena creates environmentally friendly processes and materials that contribute to a sustainable future.
The goal is to develop polymers from renewable raw materials that can be recycled after being used.
We combine innovative polymer and material development with sustainable chemical processes, thus contributing to a more environmentally friendly future.
Utilization of CO₂ as a raw material for polymers
CO₂ is filtered from the air or from point sources of emissions and converted into energy-rich molecules, including carbon monoxide, methanol, and ethylene. These molecules serve as the fundamental building blocks for polymers. The entire process is powered by electrical energy from renewable sources, making it particularly environmentally friendly.
To make such processes energy-efficient, HIPOLE develops special combinations of polymers and carbon materials. These materials are designed to selectively absorb CO₂ even in the presence of other gases and then convert it electrochemically. The goal is to ensure that CO₂ conversion requires as little energy as possible and delivers usable products that can be further processed into polymers in subsequent steps.
Development of environmentally friendly polymer materials for ion exchange membranes (IAMs)
These membranes are a key component of electrolyzers and fuel cells. Until now, they have been based almost exclusively on fluorine-containing polymers, whose production and disposal are problematic for the environment. HIPOLE Jena is therefore working on fluorine-free alternatives based on biopolymers that can compete with established membranes in terms of performance and durability.
In addition to researching new materials, we are also testing their practical applicability. For example, our polymer-based catalysts are being tested for their efficiency in application-oriented electrolysis processes. This is done, for example, by spray-coating gas diffusion electrodes to improve gas transport to the catalyst surface. These electrodes are designed to effectively convert CO₂ while being robust and durable.
