Study Abroad: Clean, Renewable Energy in Iceland

Published August 23, 2018

By

Zoe Ketola, Systems Engineering undergraduate, studied renewable energy in Iceland this summer.

Zoé Ketola enrolled in the The Green Program, which offers short-term, experiential education about the world’s most pressing issues in sustainable development. Ketola took classes through Reykjavik University School of Energy, and also traveled extensively around Iceland. In Ketola’s group there were about 20 others students, coming from Penn State, University of Michigan, Colorado State, and some Canadian universities, to name a few.

Here at Michigan Tech, Ketola is turning her innovative ideas into a reality with a BSE degree in systems engineering—an engineering degree she can customize to fit her interests. She wants to work on improving and overhauling the US electrical grid—facilitating the transition from traditional to clean energy sources.

Why did you decide to go to Iceland for your study abroad?
Iceland is what fell into my lap. It is considered the world’s renewable energy capital and renewable and clean energy are my passion. I never set out looking to go to Iceland (or anywhere, really) but when the department chair of Engineering Fundamentals, Professor Jon Sticklen, told me about the opportunity I couldn’t think of a better place to learn about what I love. Plus, have you seen pictures of the place? It’s a dream if you like the outdoors.

What was your main project while you were there?
I worked on a project that detailed providing personal solar arrays to impoverished communities within the United States. My group focused on communities in West Virginia and we looked into providing the equipment, doing install, how we would run our company, etc. We did this outside of taking courses on hydropower, geothermal, biofuels, and icelandic culture/history.What did you learn about culture and society in Iceland?
The Icelandic people are very hearty. They are independent and they kind of do their own thing. The most interesting things to me included how independent the children are and just how important keeping their public places clean is. You don’t wear your shoes in homes or the public pools. The pools also have a monitor who makes sure you shower before swimming.

“Iceland changed my life. I know that sounds cliche but I felt like I was losing my fire to make things better. I met people who cared about the same things as me and wanted to save the world. Nothing felt better than that. I can never thank my professor enough for helping me to get there.”

How has studying abroad impacted or changed your outlook?
Well, I’m itching to go back to Iceland and have been since I landed back stateside. I’m now looking more seriously at pursuing a masters dealing with energy, maybe even in Iceland. Iceland reignited my passion to help the planet and to focus on improving the renewable/clean energy sector.

Through the Green Program, Zoé Ketola studied abroad in Iceland with a strong focus on clean renewable energy

What was your most memorable experience?
I hiked a little over 10 miles at Fimmvörðuháls in the Icelandic highlands. When we got to the top of our hike, I couldn’t believe I was there. I was standing in between two glaciers with 20 fantastic people from all over the world and it was so surreal. The world is so big yet we all ended up there together.

Outside of working and studying, what was everyday life like? What did you do for fun?
Mostly spent time outside. I hiked everywhere it feels like, including near the southern coast and in the highlands (where I also camped). We visited hot springs, public pools, mountains, glaciers, and a local hostel where we got to meet a band we had started listening to that morning on the bus. We also visited Iceland’s largest geothermal plant and two hydropower plants, one of which was built in the 1960s.

What are your career goals?
I want to work on improving and overhauling the US electrical grid and facilitating the transition from traditional energy sources to clean energy sources. I don’t know what that means yet because it doesn’t look like anyone is doing exactly what I feel like needs to happen but I’ll figure it out along the way. If I quit every time I wasn’t sure of how to move forward I would never get anything done.

Advanced Sustainable Iron and Steel Making at Michigan Tech — Advanced Sustainable Iron and Steel Making Laboratory (ASISC) at Michigan Tech

International industry leaders and research engineers from mining and mineral processing are on the Michigan Tech campus Thursday and Friday for the 7th annual meeting of the Advanced Sustainable Iron and Steelmaking Center (ASISC). The meeting features speakers from India, China, Chile, Brazil, United Kingdom, Sweden, South Africa, Columbia and the U.S., as well as Michigan Tech faculty and students.

A total of 25, 30-minute presentations will take place during the meeting. This year’s theme: “New Paradigms in Mineral Processing.”

ASISC members pool resources to address a diverse spectrum of interdisciplinary research questions. During the annual meeting, they share their work and experiences to further the development of a new generation of sustainable, economical mineral processing technologies.

The meeting kicked off with Komar Kawatra, professor of chemical engineering at Michigan Tech and founder and director of ASISC, welcoming participants. Todd Davis, area manager of Tilden Mine Plant Operations for Cleveland-Cliffs, delivered the first presentation. Following Davis, Anna Edigar, also of Cleveland Cliffs spoke about the role of government relations in the iron ore industry. She also shared an update on the Cliff iron ore operation.

Janet Callahan, dean of the College of Engineering at Michigan Tech, welcomed attendees at today’s lunch at 1 p.m.

Callahan holds a PhD in materials science, an MS in metallurgy, and a BS in chemical engineering, all from the University of Connecticut at Storrs, where she is a member of the Academy of Distinguished Engineers. “Bringing together world experts to focus on sustainable ways to process iron and steel is important,” she remarked. “Each gain we make has a multiplying effect across the world.”

A Pilot Scale Carbon Dioxide Scrubber for the Michigan Tech Steam Plant

Sam Root and Sriram Valuri at work on the carbon dioxide scrubber

Meanwhile at Michigan Tech, chemical engineering undergraduate Sam Root, along with Kawatra and chemical engineering PhD student Sriram Valluri are making plans to install a pilot scale carbon dioxide scrubbing column in the Michigan Tech steam plant.

“The new equipment will scrub carbon dioxide from a sample stream of less than one percent of the main exhaust from the steam plant,” Root explains. “This will allow us to study the effects of real flue gas on carbon dioxide capture. The findings of this research will be applied in the future when designing a full-scale scrubbing operation.”

“The Michigan Tech steam plant currently produces a flue gas that is 10 percent carbon dioxide by volume,” says Kawatra. “Our goal is to use the scrubber to reduce those emissions to zero.”

The steel industry currently produces a flue gas that is 16 percent carbon dioxide by volume, adds Kawatra. Carbon dioxide scrubbers are not yet widely used in the steel industry, at least not yet.

“Making our scrubber compatible with real flue gas is the biggest challenge we’ve faced on this project. Flue gas is released from the boiler at high temperatures. It contains particulates that may be harmful to the packing inside the column. The equipment used to filter and cool the flue gas must be carefully selected to ensure that all materials are chemically compatible with the flue gas,” Root explains.

“Carbon dioxide levels are increasing, and this contributes to climate change. Capturing carbon dioxide on a large scale would be a huge step forward in mitigating anthropogenic climate effect. I am excited to work on such an important project as a young engineering student.” – Sam Root, chemical engineering senior at Michigan Tech

Master Machinist Jerry Norkol and Research Associate Stefan Wisniewski, both staff in the Department of Chemical Engineering, worked with the students to design the new scrubbing column, and also built the experimental setup. Larry Hermanson, director of energy management for Michigan Tech Facilities, is also involved in project planning and installation. In just a few months, once the test pilot scrubber is installed on the steam plant, the team will begin to examine how impurities in flue gas, such as sulfur dioxide and nitrogen oxide, as well as depleted oxygen levels, affect its ability to absorb carbon dioxide.

A Long Time In the Making
Kawatra and his graduate students have spent the past 15-plus years developing the scrubbing column technology at Michigan Tech with support from Carbontec Energy Systems in Bismarck, North Dakota. Carbontec is a developer of technologies for the energy, oil and gas and iron and steel industries. John Simmons, chairman of Carbontec, earned a BS in metallurgical engineering at Michigan Tech in 1953. He is a member of the Chemical Engineering Academy at Michigan Tech, a native of Ironwood, Michigan, and a strong supporter of Michigan Tech.

Root and Valluri will present a poster on the pilot carbon dioxide scrubber project at the ASISC annual meeting poster session.

Study Abroad: Designing Water Systems in Rural Panama

A community woman uses buckets to carry water for her family in Nidori, in the province of Bocas del Toro, Costa Rica — A community woman uses buckets to carry water for her family in Nidori, in the province of Bocas del Toro, Panama

In 2014, an I-Design team from Michigan Tech advised by Civil and Environmental Distinguished Professor David Watkins traveled off the grid to rural Panama to partner with the Ngöbe, a group of indigenous people in Nidori, in the province of Bocas del Toro. The team assessed the needs of the community, gathered data on existing water sources, and completed a survey for a new water distribution system. Below is the story of their experience.

But first, what are these Michigan Tech alumni doing now?

Kellie Heiden earned her BS in Environmental Engineering at Michigan Tech in 2015. She is now a Project Engineer at August Mack Environmental, Inc.
Tia Scarpelli earned a BS in 2015 and MS in 2016, both in Environmental Engineering. She is now a graduate student at Harvard University.
Adam Tuff earned a BS in Civil Engineering in 2014. He is now a Construction Inspector at HDR in Bellevue, Washington.
Madie Martin earned a BS in Civil Engineering in 2015. She is now a Engineer II at Kiewit in Houston, Texas.
Logan Anderson earned a BS in Civil Engineering in 2015. He is a world traveler and teacher at VIPKid and Rustic Pathways.

Grueling journey
“It was very difficult just to make it to the community,” recalls team member Adam Tuff. “To get there we flew into Panama City, took a bus to David District and stayed there for the night, then in the morning took a bus to Chiriqui Grande, then a small boat. The community is definitely off the grid.”

The rural area is part of the Ngöbe-Buglé Comarca, one of the areas set aside by the government for the various indigenous groups of Panama. The Ngöbe people rely on water transportation throughout the community, often by canoe, due to the location of the homes and schools, as well as the rough surrounding terrain.

Quebrada y pozo
“Our project was a little complicated, as we serviced one community with two smaller aqueducts,” explains team member Kellie Heiden. “The first portion of our project came from the newly found quebrada ‘mountain stream’ water source. We utilized this source by designing a stream dam that siphoned water through PVC pipes to five homes that currently have no water distribution system at all. This means that they carry buckets to and from a water source a few times a day to get adequate water. The second portion of our project collected water from the pozo ‘spring’ water source. This required the designing of a spring box and a distribute tion line that feeds into a concrete tank. The water collected in the tank will be used to service twelve homes that have a water distribution system only during the wet season.”

The team designed a stream dam that siphoned water through PVC pipes to five homes that had no water distribution system at all

Working closely with community members
“It was difficult to figure out how we could design a simple system that would last,” adds Tuff. “It is not the same as designing a system in America where the people and parts needed to fix problems are readily available.” The team worked closely with the community members to figure out what they would be able to maintain.

Good prep for the Peace Corps
Back on campus, they produced a report in both English and Spanish detailing the design process, technical design components, construction, maintenance, feasibility, recommendations, and impact their project will have on the community.

“Our time in Panama was difficult due to factors like weather—full days of rain—and access limitations. Just getting to the sites was an adventure,” says team member Tia Scarpelli. “But the field experience was very rewarding. The people of Nidori really wanted to know how they could help.”

Adds Scarpelli: “Studying abroad and especially programs like iDesign are very helpful if you’re considering something like the Peace Corps—it will give you a great snapshot of what that sort of experience is like without the full-on commitment.”

Study Abroad: Investigating Myocardial Graft Materials in Hannover

Published July 30, 2018

By

Michigan Tech MSE student Jacob Braykovich studied abroad at Leibniz University Institute of Materials Science.

Jacob Braykovich, a materials science and engineering major at Michigan Technological University, had spent two years working in the Michigan Tech Surface Innovations lab, helping to develop biodegradable zinc-based cardiac stents. He had a summer internship at start-up InPore Technologies, working on polymeric water filtration systems. But he wanted to do something different during the last summer before earning his undergraduate degree.

Braykovich thought about going overseas, and began looking into options. That’s when he discovered the RISE program, or Research Internships in Science and Engineering. The RISE program is for students in the USA, Canada, or UK who want to spend a summer researching science or engineering at German universities. Braykovich applied for and won a scholarship to attend Leibniz University in Hannover, Germany.

Braykovich joined a team of researchers at Leibniz University Institute of Materials Science working on myocardial graft materials. Myocardial grafts, both biological and synthetic, are used to help restore damaged myocardium, or heart muscle. Whether from heart attack or disease, damage to the myocardium can result in scar tissue, which can diminish the heart’s ability to contract and pump blood effectively.

“The Liebniz team, led by Hans Jürgen Maier, has developed a biodegradable magnesium alloy scaffold designed to mechanically support a myocardial graft and then gradually lose its function as the graft develops its own strength,” Braykovich explains.

Biodegradable scaffolds are cut with a water jet at Leibniz University Institute of Materials Science

“The work was similar to my research here at Michigan Tech, so I was able to hit the ground running,” he says. Braykovich worked on perfecting the abrasive water injection jet cutting strategy employed to produce the scaffolds—analyzing design, cutting-edge roughness, and burr generation. “I ultimately determined the optimum pressure, flow rate, abrasive size and material, traverse rate, and orifice diameter of the cutting technique,” he says.

He started each day with coffee and a pastry from a local bakery and headed to work on the train. His tasks at work ranged from cutting samples in the manufacturing facility to using the 3D laser microscope to take images of the cuts, which he then analyzed.

“Through the experience, I found the hierarchy of the education/research system at Liebniz to be much different than what I have known, and with that the expectations were much different. But through making mistakes, I gradually began to understand and appreciate the diverse culture,” he says.

Leibniz University Institute of Materials Science

Outside the lab each weekend Braykovich traveled solo to a new city or country. Berlin, a short 90-minute train ride from Hannover, was his favorite city. “There are people living in Berlin from almost every country you can possibly imagine, making the cultural dynamic something unlike I have ever experienced,” he says.

“Ultimately, working in a foreign country has allowed me to see past my current horizon onto new ideas and experiences,” adds Braykovich. “It taught me how to take a leap of faith into any unknown situation.”

Jacob Braykovich earned a BS in Materials Science and Engineering at Michigan Tech in 2015. He is now a PD Quality Engineer at Ford Motor Company in Dearborn, Michigan, where he is responsible for delivering quality of all interior functions for future Ford F-150 trucks.
