ExpACT: Exposome ACTions perspectives for a healthy air quality environment
Date: 8/11/2024
We are proud to announce that TDLab is part of an interdisciplinary consortium that has received a € 6,7 million grant from NWO within the Research on Routes by Consortia (ORC) programme line of the Dutch Research Agenda (NWA-ORC).
Our project ExpACT: Exposome ACTion perspectives aims to focus on an actual societal problem impacting the public health: an increased exposure of citizens to potentially harmful air emissions of emerging chemical and biological substances.
The quality of air we breathe when we walk, at home or at workplace is changing continuously together with the world around us. The current societal transitions (i.e., mobility, energy, circularity, food systems) have a large impact on the air components. We are witnessing daily political and societal debates about (emerging) industrial and agricultural emissions, urban pollution and exposure at workplace. In all these discussions, the uncertainty about the exposure to pollutants and their potential health effects plays a central role.
There is a clear need to improve our ability to dynamically measure air quality in situ and in real-time. Therefore, one of our ambitions in ExpACT is to develop methodologies to go beyond citizens science, and stakeholder engagement and including the ethical, legal and societal aspects of the technologies.
In this project, the TDLab team received € 840,000 to develop and apply two innovative techniques for in-situ detection and monitoring of the chemical exposome in air at different length scales.
(1) The field-deployable mid-IR coherent open-path spectroscopy (COPS) instrument to measure chemical exposome components in air. This will be combined with the satellite spectroscopy for mapping the air pollutants with unprecedented accuracy, high spatial and temporal resolution.
(2) Mobile Time-of-Flight Mass Spectrometry (ToF-MS) for real-time chemical analysis of volatile organic compounds and (organic) aerosols. Here, we go beyond the state-of-the-art by including an innovative particle inlet system that will allow the extension of the range of detectable molecules to semi-volatile, intermediate-volatile and low-volatile organic compounds (e.g. polyaromatic hydrocarbons - PAHs).
“I am grateful to my team members Amir Khodabakhsh and Joris Meurs who help me with taking this important role in such a unique project and we are looking forward to it!” (Simona Cristescu).

Date: 26/9/2024
Researchers from TDLab have teamed up with 58 international parties from research and industry to work together on more sustainable production of hydrogen by electrolysis & plasma technology.
The HyPRO project received a subsidy of €34.5 million and a total budget of €50 million within WP1 of the GroenvermogenNL, becoming the largest R&D project into green hydrogen in the Netherlands to date.
GroenvermogenNL
Like the rest of the world, the Netherlands is faced with an immense climate challenge. As part of the Nationaal Groeifonds, GroenvermogenNL is the Netherlands’ approach to transform a fossil-based society and industry towards a green future. Green hydrogen acts as a tractive force to support this transition. Large scale process industry, as well as decentralized applications need green hydrogen as a key element in the transition to carbon neutrality.
Plasma-based methane conversion to hydrogen through offers a promising route for sustainable hydrogen production, thanks to its high efficiency, flexibility, and product customization possibilities.
Industrial residual gas valorization
Centralized large-scale conversion of industrial waste methane to hydrogen and C2 molecules in the context of the tail gas from naphtha crackers is a national priority. Rather than burning the methane for energy, better use it to produce plastic precursors, like ethylene or acetylene, and effectively increase the carbon efficiency in the process. Together with plasma specialists from Univ. Maastricht, TDLab will be involved in performing research on the efficiency of industrial residual gas valorisation by methane pyrolysis in innovative plasma reactors. In particular, we will design a multispecies gas detection system to measure the products relevant for optimizing the plasma conversion and improve the current prediction models. “We are looking forward to this broad collaboration and connection with the industrial parties.” (Simona Cristescu).

NWO Open Technology Grant on green chemical industry
Date: 4/6/2024
The project "Accessing ultrafast timescales to achieve a climate neutral chemical industry", a collaboration between the Life Science Trace Detection Laboratory (TDLab) and Brightsite Plasmalab of Maastricht University (Group of Gerard van Rooij), has been awarded a NWO Technology Grant. The Open Technology Programme, funded by the Dutch Research Council (NWO), provides funding for application-oriented technical-scientific research that is free from disciplinary boundaries. The programme offers companies and other organizations an accessible way to participate in scientific research that is intended to lead to societal and/or scientific impact.
About the project
As the chemical industry shifts to electrified and circular chemical processes, methane will increasingly become a bottleneck in closing the carbon cycle. It is crucial that methane is valorised rather than burned for energy to avoid CO2 emissions. This project develops ultrafast plasma pyrolysis of methane to ethylene as an innovative and economically viable technology for methane valorisation. It requires fundamental understanding of the chemical kinetics taking place on time scales of microseconds, which is within reach by combining an advanced pulsed microwave plasma reactor and a unique infrared spectroscopy method so called time-resolved dual-comb spectroscopy.
This project is a collaboration with Brightsite Plasmalab of Maastricht University (Group of Gerard van Rooij) located at Brightlands Chemelot campus. Plasmalab builds a pulsed microwave discharge plasma reactor capable of incorporating laser-based spectroscopy instruments for time-resolved monitoring of the reaction dynamics. TDLab will develop a state-of-the-art ultra-broadband time-resolved dual-comb spectroscopy system with both high spectral and temporal resolution. The partners then combine the two instruments to study the plasma-chemistry in depth and enhance the efficiency of ethylene formation.

HyTROS initiative into large-scale hydrogen transport and storage technologies
Date: 12/10/2023
Researchers from TDLab have teamed up with 32 parties from research and industry to work together on developing safe and cost-effective solutions for HyTROS - “Hydrogen Transport, Offshore and Storage” within the WP2 of the GroenvermogenNL.
Among other aspects, the safety of the operation and the quality of the delivered hydrogen is one of the focus points that is addressed in HyTROS, an 18 million euros subsidy from the Dutch government and 18 industrial partners. Researchers from TDLab in association with the Dutch national metrology institute (VSL) and University of Applied Sciences Nijmegen (HAN) will develop and test analytical solutions and instruments for reliable measurement of impurities in the hydrogen. TDLab will investigate the sources of hydrogen contaminations to find the most important species and their potential concentration levels expected in the real-life application. Based on the outcome of the study, TDLab will design a multispecies gas detection system for the detection of these contaminants.
This provides a tailored solution for the detection of hydrogen contaminations arising from different infrastructures previously used for natural gas and guarantees the utilization of the state-of-the-art trace detection technologies in our green hydrogen ecosystem, being developed in coming years.
