ACTNXT survey

To reach its climate neutrality goals Europe needs to rely heavily on Power-to-X (PtX) technology to replace the many applications of fossil fuels that are not easily electrified. Many PtX technologies are however still immature or not ready for deployments yet, highlighting the need for a sustained R&D effort in the field.

Neutron- and synchrotron sources can play a crucial role in this effort, however lack of key instrumentation is limiting the current possibilities.

ACTNXT will upgrade the instrumentation at current neutron- and synchrotron sources to enable it to provide crucial knowledge within PtX areas such as efficiency, safety, price, raw material consumption, and durability. This will be done by developing instrumentation for:

1. Operando measurements of processes and flow inside PtX components

2. Materials behaviour under hydrogen exposure

3. Reliable and high throughput investigation of novel materials

4. Operando measurements of hazardous chemical reactions

The new instrumentation will be designed for broad adaptation as upgrades for many existing research instruments across Europe. Prototypes of all 4 instrumentation types will be constructed at leading research infrastructures and their capabilities tested and demonstrated. This is supplemented by a common knowledge platform addressing common challenges such as safety and planning of complicated experiments.

During the project, the consortium will have a very strong dialogue with the user communities to ensure that the developed instrumentation matches its needs and that it is ready to take full advantage of the instrumentation also after the end of the project. In doing so ACTNXT aims to give the European green industry a huge boost and ensure that it captures a major part of an emerging trillion Euro PtX market.

Thank you for participating in this survey. The purpose of the following questions is to ensure that the instrumentation developed in ACTNXT will have the maximum impact on the PtX community.

This data will be used only for the purpose of gathering information for the ACTNXT project and will be erased after that.

To proceed, we kindly ask you to check the box below. For more details see our privacy policy.

We are sorry but you can't proceed without first agreeing to our survey data policy.

I agree to my answers being saved in a database for the purposes of gathering information for the ACTNXT project.

D4: Would you be interested in the utilization of an in-line glovebox for (operando) neutron imaging experiments?

In case you would like to know more about neutron imaging and its broad range of applications, please visit the following websites (What is Neutron Imaging ? | Applied Materials | PSI) (Research at Applied Materials Group | Applied Materials | PSI). Alternatively, more detailed information about the state-of-the-art neutron imaging can be found in the recently published book (Neutron Imaging - Book - IOPscience).
