xemX – The proper catalysts at the right time


With the help of a gigantic database, xemX want to provide assistance to the most important players in the hydrogen world on the subject of noble metals.

To meet the rapidly increasing demand for catalysts for the worldwide production of hydrogen, new, more available and more powerful catalysts are needed.Lars Banko, xemX

The big hydrogen hype is encountering various hurdles. One of them is called noble metals. To ensure that the key players in the industrial transformation can nevertheless maintain their course towards hydrogen, xemX is compiling a database that encompasses chemically complex electrocatalysts. Founder Lars Banko tells us exactly what this database looks like, which target group will benefit from it and what challenges the team is still facing before the founding.

Who are you and what do you want xemX to stand for?

At xemX we generate the largest experimental database of chemically complex electrocatalysts to provide our customers with customized high-performance materials. We enable our customers to power the green energy transition by offeringthem catalysts adapted to their needs in terms of performance, availability, and sustainability.

Noble Metals are central in the current hydrogen market. What is the problem here? 

Today, roughly eight elements, mostly noble metals, from the entire periodic table are used as catalysts. Using currently available catalysts and technology fulfilling the hydrogen strategy of the German government alone would need more than the annual production of iridium. To meet the rapidly increasing demand for catalysts for the worldwide production of hydrogen, new, more available and more powerful catalysts are needed.

What makes your catalysts the solution to this challenge?

It is rather our research approach. xemX uses data-driven high-throughput experimentation to find new high-performance catalysts. We can perform up to 5.000 experiments a week and there are already 800 years of traditional experimentation in our database. Our research approach is enabling us to identify rapidly the right material candidates for the specific needs of our customer.

You are still in the start-up phase - but how would you define your target group up to now?

We guide the planning of further R&D efforts by clear surveys and benchmarks of potential catalyst materials based on our customers boundary conditions. Our target groups are manufacturers of catalysts, fuel cell and electrolyzer components.

At the H2UB Start-up Sprint you receive a lot of support from experienced mentors and industry experts. What are your biggest challenges that you want to tackle?

We are facing two main challenges: (1) developing, validating, and deciding on a business and revenue model for our services and (2) demonstrating the transfer from high-throughput screening to application testing of our catalysts.

About the H2UB Sprint produced by BRYCK:  

It is a 10 week coaching program, that takes place twice a year. It is specifically designed to help start-ups accelerating their business by providing the right impulses, adapted to their needs. During the program the founder teams concentrate their efforts on selected core challenges, supported by group and 1:1 coaching sessions with dedicated business mentors of our partner BRYCK and hydrogen industry experts. The kick-off, interim and investor pitch presentations are organized as on-sites at our BRYCK tower in the heart of Essen, to enjoy the dynamical team spirit of the group, whereas most of the coaching sessions take place in a virtually workspace. The H2UB Sprint program is fully funded by H2UB, supported by its corporate partners and the state of North Rhine-Westphalia.
