Hello! I’m Kelly Jones and I’m learning overseas at Denmark Technical College (DTU) in Copenhagen. I examine Supplies Science and Engineering and have a focus in Supplies for Renewable Power.
Upon being accepted to check at DTU, I used to be ready to decide on what lessons I’d take throughout my examine overseas. My main focus is in Supplies for Renewable Power, which drove me to have a look at DTU’s lessons that concentrate on sustainability. I used to be delighted to see what number of choices I had. I used to be capable of fulfill practically all of my technical electives with lessons that targeted on strong renewable power applied sciences: from gasoline cells to batteries and in all places in between. I made a decision to join DTU’s class referred to as “Inexperienced Fuels and Energy-to-X” (P2X). Not completely certain what the category would entail, I used to be intrigued by the final description of the course, and it fulfilled my final technical elective requirement, so I confirmed my enrollment.
From the primary day of sophistication, I rapidly discovered that P2X refers back to the fully renewable course of and inexperienced electrification of every part! This usually includes the manufacturing of inexperienced hydrogen or artificial and sustainably produced fuels and chemical compounds. The category targeted on the completely different processes to provide e-fuels, that are artificial fuels usually produced from hydrogen and carbon dioxide, all powered by renewable power. I used to be launched to the intricacies of methanol, ethanol, and ammonia for gasoline. The professor not solely defined how every of those e-fuels might be created, but additionally how all of those applied sciences might be included into current digital and gasoline based mostly techniques. The curriculum went over the the present applied sciences for using every gasoline and the way environment friendly they’re for every use-case. The category additionally featured talks from trade professionals from firms in Denmark that specialised in these applied sciences. For instance, an individual got here and spoke about gasoline cells and electrolyzers and the way their merchandise could be used because the beginning molecules for e-fuels. Moreover, the curriculum defined carbon seize and the way it may be utilized to provide blue hydrogen (blue hydrogen nonetheless produces carbon, however by way of steam reforming one other different processes, the carbon will be separated and saved underground as an alternative of being launched into the ambiance). An trade skilled spoke about biomass and his firm’s growth of carbon seize expertise to make the manufacturing of e-fuels extra sustainable.
The ultimate undertaking of this class tasked my group with designing a totally renewable system utilizing one of many e-fuels. My group determined to mannequin the manufacturing of ammonia and analyze how the fluctuations of wind and photo voltaic power in Denmark would influence the method if the ammonia manufacturing was absolutely renewable. The 40 web page paper my group turned in was the outcomes of weeks of labor and actually put the inexperienced transition into perspective. I discovered precisely how a lot land and energy could be required to provide a certain quantity of ammonia, and my group analyzed the ammonia for use in long-haul maritime transport. I’m grateful that I had the chance to design a totally sustainable system and evaluate it to different typical fuels as a result of not solely do I essentially perceive what infrastructure must be carried out to permit for inexperienced power to take over, however I can take data I discovered and apply it to different e-fuels for various makes use of. Due to my experiences on this class and the broad data I discovered about renewable power sources and e-fuels, I’m excited to start my profession after commencement to assist hasten to inexperienced transition by analysis completely different strategies and serving to develop new expertise.
Listening to from all of those folks about their actual world experiences and studying concerning the completely different ways in which fuels will be transformed to greener means gave me hope in the way forward for the planet. Rising up within the US, I knew that local weather change was an ever looming situation and was straight impacting the entire globe, however I used to be by no means certain if there was a technique to divert people from the trail of fossil fuels. It felt like environmental coverage by no means aligned with the scientific data the world had about local weather change, and I had an ever current feeling of dread and pessimism concerning general actions for making the world extra sustainable. I desperately wished to assist the atmosphere, however was unaware of the applied sciences and the way they might be carried out to make the world extra sustainable. Taking this class opened my eyes to all the potentialities for a way firms and governments can change the trajectory of local weather change. I’m impressed by the actions and funding of nations around the globe and was excited by what number of younger engineers wished to deal with the local weather drawback. I now perceive attainable options to standard fuels and perceive the selection and developments that must be made to public infrastructure to hasten and permit for the inexperienced transition. Being within the class gave me hope that there are such a lot of engineers around the globe, all working collectively to make this transition occur. I discovered that among the expertise won’t be there but, however the primary issue holding the implementation of those fuels again is the dearth of infrastructure and industrialization of those fuels. Lots of the applied sciences are able to producing huge quantities of electrical energy and chemical compounds to provide the fuels, however there’s an general lack of funding from governments and the personal sector. The nation of Denmark has made nice strides in changing into reliant on inexperienced power and investing in personal firms that concentrate on the event of inexperienced applied sciences, so I hope that they’ll function a mannequin for different international locations to comply with.
