Introduction

Applied and basic research (experimental coupled with targeted modelling and simulation activities) carried out by our group is designed in the context of holistic approaches to key technological areas. The aim is to make such approaches mature for industrial exploitation while promoting innovative products and processes for sustainable, environmentally friendly and energy and resource efficient power generation for stationary and mobile applications, in line with the principles of circular economy and industrial symbiosis.

Main technological targets:

  • Deep decarbonization of energy-intensive industries and long distance transportation
  • Carbon capture storage and utilization
  • Development of novel combustion concepts utilizing alternative, low-carbon and non-carbon fuels.
  • Membrane-based physicochemical processes
  • Emissions mitigation and environmental protection
  • Exploitation of low cost, non-toxic materials and industrial byproducts for agricultural, environmental and energy related applications in the context of circular economy

Areas of Research & Development

A. Deep decarbonization of energy-intensive industries and long distance transportation:

Fossil fuels will remain a major energy source for the power and process industries, as well as for long distance transportation. Decarbonization of energy-intensive industries and hard-to-electrify systems and process can be accomplished through switching to low-carbon and non-carbon fuels and by the integration of post-combustion carbon capture utilization and storage (CCS) in existing systems and processes. CCS combined with plant operation on zero-carbon fuels (incl. biofuels) is one of the few alternatives for Net Zero Carbon Emissions. Integrated solutions for the maritime sector: The maritime industry is facing a unique challenge as currently enforced and forthcoming stringent emission and generally environmental regulations are transforming the ship powerplant by introducing a complete chemical plant including emissions mitigation and control. This has to be dynamically coupled with the main propulsion and power generating modules (increasingly operated with alternative fuels) and the overall ship design. Ship designers and operators usually lack the necessary training and expertise to integrate chemical processes.  The Chemical Digital Ship services provide integrated multiscale modelling and simulation tools for the shipping industry including computational materials, component, process and systems simulation, techno-economic, LCA and MCA assessment. The Chemical Digital Ship services target Shipping companies, Shipyards, Classification Societies, OEM Companies, Engineering Consulting Companies.
