Internships HyGear

Arnhem, Gelderland, NetherlandsInternships

Job description

For the HyGear engineering department we are looking for interns! The following internships / graduation assignments are available. Apply using the apply button and select the (graduation) internship you are interested in.

Optimization of CO2 capture system

HyGear has developed a CO2 capture system to reduce the emissions from its hydrogen generation systems and from other flue-gases. The system is still in development and lots of different parameters can be adjusted to improve its performance (e.g. reduce electricity costs, remove NOx and SOx, increase capture rate). During this internship you will learn a lot about CO2 capture with PSA technology and with this knowledge you will model different cases to reduce electricity costs and increase the CO2 capture rate. 

Your tasks:

  • Map all the different parameters influencing the performance of CO2 capture; 
  • Model different parameters to figure out the main influencers;
  • Define a test plan to optimize the operational conditions;
  • Test and validate the new operational conditions.

Techno-economic analysis electrolysers

Suitable only for Master Students

Electrolysis in combination with renewable electricity is seen as a low-emission hydrogen production technology. However, there are multiple different ways to perform electrolysis in terms of different membranes and operating conditions (using steam or water). During this internship, different technologies will be compared on a technical and economic point of view, consisting of process modelling, cost calculations and market analysis. After this internship you will become an electrolysis expert.

Your tasks:

  • Compare processes and model different electrolysis technologies (AE, AEM, SOE, PEM, PCE);
  • Optimize different process models;
  • Compare the different technologies in a cost breakdown (CAPEX and OPEX);
  • Define different markets where these technologies could fit best.

Techno-economic analysis high pressure reforming

The hydrogen generation systems at HyGear produce hydrogen up to 10 bar(g) with the use of (bio)-methane in a steam methane reforming reactor. With an increasing hydrogen mobility market, the aim is to increase this pressure up to 30 bar(g). In this internship, you will model the high pressure system (30 kg H2/h), define different cases and come up with the best configuration in terms of technical and economical scope.

Your tasks:

  • Define different PFD’s for a high pressure SMR system;
  • Model the different PFD’s and create heat and mass balances;
  • Define the best case in terms of technical and economic feasibility;
  • Define the risks and opportunities of the chosen PFD.

Regional Subsidy Internships

Suitable only for Master Students Technical Business Administration

Hydrogen is considered as the important energy carrier for the future. This opens new market opportunities. The regional governments are subsidizing the energy transition by hydrogen. In offer to provide best advice for our customers, we help them with the most economical hydrogen solutions for the installation as well as the operation. Within the European Community as well outside EC different ways of subsidies exist as well as definitions of types of hydrogen. During this internship, different technologies and different national calculations will be compared on a technical and economic point of view, consisting of process modelling, cost calculations and market analysis. After this internship you will become an international sales engineer.

Your tasks:

  • Compare processes and subsidy models different per country and per technology;
  • Optimize different sales and cost calculation models;
  • Compare the different technologies in a cost breakdown (CAPEX and OPEX);
  • Compare the different definitions of hydrogen (green, low carbon, sustainable);
  • Define different countries where these technologies could fit best.

Job requirements

Who are you?

  • BSc / MSc in Chemical Engineering / Mechanical Engineering / Sustainable Energy;
  • Interested in sustainable energy technology;
  • Plan-minded and independent worker.

What do we offer?

  • Working at the technology forefront of the energy transition;
  • Groundbreaking tech company in the field of biofuels, carbon capture and thermal conversion;
  • Minimum wage based on 40 hours per week for interns with an EU working license / Monthly fixed fee of € 400 based on 40 hours per week for students without an EU working license. Please note: it depends on your type of internship at HoSt which fee you receive;
  • Lots of responsibility and room for own initiatives;
  • Professional support, guidance and insights;
  • Interesting international environment only a 5-minute walk from the ‘Kennispark’ train station in Enschede;
  • Nice and sustainable welcome gift;
  • A dynamic, energetic, passionate young team;
  • Flexibility in working from home / office.
