Internships Bright Renewables

Enschede, Overijssel, NetherlandsInternships

Job description

For the Bright Renewables 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.

CO2 Liquefaction

Bright has developed technology for liquefaction CO2 from biogas upgrading or carbon capture installations. The first installations are installed and currently in starting-up or running. During this internship you will monitor the installations, collecting and analyze data. The main goal is to identify the CO2 recovery and energy consumption and improve energy efficiency and/or recovery the installation.

Your tasks:

  • Monitoring and analysis of plant data;
  • Recommendations for improvement;
  • Research options for heat recovery and integration;
  • Setup and execute test plans to confirm hypotheses.


Bright delivers biogas upgrading systems, in these systems methane and carbon dioxide are separated using membrane technology. Thereby, the methane quality is enriched for injection in the natural gas grid. Before the biogas is ready to processed in the membrane, sulphur compounds (H2S) need to be removed. In this internship you will design and engineer a novel method for desulfurisation of biogas.

Your tasks:

  • Setup of process flowsheet and PID;
  • Preparing mass and energy balances;
  • Design of heat exchangers systems for heat recovery;
  • Engineering of sulfur removal system.

Landfill Gas Upgrading

Bright is already a global leader in the upgrading of biogas. Another source of renewable gas are landfills all around the world. Our upgrading technology is (partly) suitable to upgrade these gasses, however another technique is additionally required to achieve our well-known biomethane and liquid CO2 products. Recently, this technique has become well-known in the HoSt Group. Hence, in this internship you will do the basic design of the overall system (mass- and energy balance, optimalization).

Your tasks:

  • Collection all necessary information within the HoSt Group of all required techniques;
  • Create a Mass- and energy balance over each technique and overall;
  • Perform a parameter sensitivity study to define the parameter limits;
  • Advice regarding optimal configuration.

Simulation of Carbon Capture under Dynamic Conditions

Only  MSc

Bright Renewables has a brand-new system which can capture CO2 from point sources. These point sources can be flue gasses from Combined Heat and Power installations, but also other processes. This system is entirely simulated in Aspen Hysys to understand the behaviour of the system (steady-state and the beginning of dynamic conditions). This internship goes further into detail regarding dynamic simulation of the Carbon Capture system. For instance, the dynamic behaviour during day-night rhythms, the effect of system size, during short start-stops of the CHP, what short term impurities (SOX, NOX) have effects on the CO2 purity 

Your tasks:

  • Background information about dynamic process and control;
  • Aspen Hysys simulation set-up;
  • Simulate and understand the effect of dynamic external effects;
  • Give a clear advice for Bright Renewables how to deal with these effects.

Membrane testing

Bright delivers biogas upgrading systems, in these systems methane and carbon dioxide are separated using membrane technology. Thereby, the methane quality is enriched for injection in the natural gas grid. In this internship you will experimentally determine the performance of (novel) membranes for application in production of BioLNG. For this application CO2 needs to be removed almost completely, down to 50ppm.
Part of the assignment is installing the membrane setup, validating the experimental method. Experimentally proof we can reach CO2 levels below 50ppm and optimize operation conditions for this deep removal of CO2.

Your tasks:

  • Installing of membrane setup;
  • Validating experimental method;
  • Planning and performing experimental work on (biogas) test location;
  • Processing and analysis of experimental data;
  • Ecommendations for process design.

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.
