Integrated Framework to Measure Sustainability of Desalination

Team Develops First Index to Account for the Sustainability Performance of Desalination Technologies

In water-scarce urban environments like those of the UAE, desalination technologies play a central role in transforming plentiful saline and brackish water to create freshwater that meets the population’s needs. In the UAE, natural gas-powered thermal desalination is estimated to produce around 80% of the country’s domestic water.

However, desalination is not an entirely benign process, with associated economic, environmental and social impacts. This makes ensuring that desalination does not harm the very environments and populations that they are meant to help support an ongoing challenges. In response to this need, a Khalifa University research team has collaborated with both international and regional experts to develop the first universal integrated framework to assess the sustainability of desalination technologies.

“As far as we could find out, there was no unified sustainability metric to measure the sustainability of a desalination plant in the UAE. That is why we decided to formulate a comprehensive framework for the UAE, to generate a sustainability index that takes into account the four factors of sustainability, which are environmental, social, technical, and economical,” explained Dr. Faisal AlMarzooqi, Assistant Professor of Chemical and Environmental Engineering at Khalifa University.

A paper on the framework titled “An integrated framework for sustainability assessment of seawater desalination” was recently published in journal Desalination, co-authored by research associate Yazan Ibrahim, Dr. AlMarzooqi, Professor of Chemical and Environmental Engineering Dr. Hassan A. Arafat, and Professor of Engineering Systems and Management Dr. Toufic Mezher, all from Khalifa University.

“What makes desalination a different and more urgent challenge than ever before, is the rapid evolution of this region in its social, environmental, and economic contexts. This led to a significant dependence on desalination as a reliable freshwater alternative due to the geographical and geological structure of the UAE that limit the number of natural water resources,” Ibrahim shared.

The framework developed by the team combines different desalination-related sub-factors and covers the four sustainability factors. It took a unique methodological approach to integrate the different framework components to be able to assess the sustainability of any desalination technology worldwide. The framework consists of three levels, the first being the goal sought to be reached, the
second level being the main sustainability factors and the third being the sub-factors assigned to each factor.  The framework was then demonstrated by assessing the sustainability of the three main desalination technologies in the UAE, which are multi-stage flash distillation (MSF), multiple-effect distillation (MED), and seawater reverse osmosis (SWRO).

“SWRO, which is a membranes-based process, is the most widely adopted technology worldwide, with a global share of around 68% in 2018. It is characterized with low environmental impacts, low cost, reduced land use, and ease of operation. On the other hand, MED and MSF, which are thermally-based technologies, are known for their reliability and robustness as well as their high environmental footprint. Therefore, the challenge for sustainable desalination today lies in the ability to find a tradeoff between the economic, social, and environmental aspects of these technologies,” Yazan explained.

Overall, the three main sustainability factors were environmental, techno-economic and social, each of which had 5-6 desalination-related sub-factors, which were selected from published literature and expert opinion on the topics. The technical factor demonstrated the technically feasible of the technology. This is closely related to the economic factor. Therefore, the team decided to combine those two factors into one representative factor namely techno-economic. Some of the sub-factors included water extraction and discharged brine impacts in the environmental factor, quality of produced water and scaling and fouling propensity in the techno-economic factor, and technology safety and level of noise in the social factor.

When the framework was applied to the three major types of desalination technologies used in the UAE, SWRO was found to be the most sustainable technology followed by MED and MSF.

“This was due to the unique local conditions and parameters of the UAE – like the relatively low price of natural gas and the relatively higher weightage of environmental impact. That is why it is important to calculate the sustainability of a technology in a way that is specific to its local application. In the future if new technologies emerge, these too can be added to the index and framework,” Dr. Al Marzooqi explained.

The team is now working on the technological aspects of sustainable desalination and hope that opportunities are generated in the near future to further develop sustainability indices.

“Till date, the economics and efficiency of sustainable desalination technologies are not able to fully replace traditional desalination technologies. Sustainable desalination technologies are still awaiting a technological breakthrough to give it a competitive advantage against traditional desalination technologies. This research will serve as a performance metric for sustainable desalination. This will benefit the UAE and the world by enabling the government and regulatory bodies in measuring the
current sustainability of desalination plants and setting future targets which will help in achieving other sustainability related targets such as climate change and other,” Dr. Arafat added.

And though the team’s framework was developed to test the sustainability of desalination technologies in the UAE, it can be universally applied to other desalination technologies and/or other countries.

Their research has also been presented through two conference presentations – one at the International Desalination Workshop that was held in Busan, South Korea in November 2017, and another at the Desalination for the Environment Conference of the European Desalination Society that was held in September 2018 in Athens, Greece.

Four Electrical Engineering Students Selected for Stanford Fellowship

Student Projects to Increase Campus Engagement and Become Agents of Change

Four students from the Khalifa University Bachelor’s in Electrical Engineering program have become the first-ever group to be selected from the UAE for the University Innovation Fellows (UIF) program at Stanford University in the US.

The global program run by Stanford University’s Hasso Plattner Institute of Design (d.school), empowers student leaders to increase campus engagement with innovation, entrepreneurship, creativity and design thinking. It encourages students to become agents of change at their schools, and work towards ensuring that their peers gain the knowledge, skills and attitudes required to compete in the economy of the future and make a positive impact on the world.

The four – Hajer M. Almahri (2020), Maryam Abbas Sajwani (2019), Ruba Nasser (2019), Buthaina Alkhayat (2020) – have now completed their six-week online training program. The team, along with faculty mentor Dr. Nicholas Dimmitt, Associate Professor, Department of English, will now be invited to the Silicon Valley Meetup in California, US, where they will attend experiential workshops and exercises focused on topics including movement building, innovation spaces, design of learning experiences, and new models for change in higher education. The team’s visit will also include a day of activities and learning at the headquarters of Google (Alphabet) in March 2019.

Additionally, in Spring 2019, the team will attend as ‘special guests’ in the Eastern Hemisphere Meetup in Dubai, organized for teams from China, India and Far-East Asia.

Dr. Arif Sultan Al Hammadi, Executive Vice-President, Khalifa University of Science and Technology, said: “The selection of our students by Stanford illustrates the relevance of Khalifa University’s innovation and entrepreneurship ecosystem and our faculty expertise in skill-building. Our students need to be encouraged to come up with such practical, need-based projects that are useful, and concepts that can be implemented by the university. We believe our students will bring more honor to our university through such innovative projects that they will co-create with stakeholders in the coming months, ready for presentation at Stanford and elsewhere in the world.”

The four Khalifa University students will now begin to plan and activate their projects that are the outcome of their training.

Ruba Nasser and Buthaina Alkhayat are working together on two projects. Their LabAID project is a resource-design around laboratories that helps better understand what the lab sessions talk about and includes a demonstration of experiments.

Nasser said: “I plan to complete my project to collaborate with one of the lab instructors who taught me a lab that I already took and create the videos, and observe the difference on how well the students are grasping the lab experiments.”

The ‘Workshops on emotional intelligence’ project aims to help students build self-confidence and raise self-expectations as well as focus on achieving specific goals despite daily distractions.

Alkhayat said: “Right now, Student Services hosts various workshops to encourage students to practice introspection and reflection, which are fundamental aspects of emotional intelligence.  Also, a one-credit course is also being developed to focus on the fundamental skills university students need, introducing habits of mind and provides real life scenarios for students to approach. A student led group will be creating an online portal that encourages registration for this course and provides feedback.”

The project by Maryam Abbas Sajwani focuses on ‘Facilitating students’ engagement through communication systems’, and aims to help students distinguish events that are happening on-campus, allowing them to be more interactive with specific interests.

Sajwani said: “My next step to make this project a reality is to create a web-based preliminary application, incorporate possible events and test its functionality. I wish to work on it in small sections, then collate all to make a fully furnished app design.”

Hajer Almahri’s project, ‘Freshman Year Experience’ (FYE) program or ‘Freshmen Success Program’, is designed to facilitate transition from high school to university, while helping students to interact with one another socially.

Almahri’s said: “The FYE program will cover two main aspects, educational and social. For the educational aspect, it will consist of a three-credit course that will introduce the students to different majors in the university. For the social aspect, it will make sure students remain engaged on-campus by attending events and workshops, and off-campus by attending exhibitions and fieldtrips.”

Throughout the year, the four UIF students will have many opportunities to learn from one another, Stanford mentors, and leaders in academia and industry, while presenting their work and facilitating workshops at events and conferences around the world.

Students Develop Patient Care Apps with Sheikh Zayed Institute for Pediatric Surgical Innovation

Apps developed during Eight-Week Internship at Children’s National Medical Center in Washington DC

Two of Bachelors of Computer Engineering students have successfully developed prototype apps for patient care as part of their internships at the Sheikh Zayed Institute (SZI) for Pediatric Surgical Innovation at the Children’s National Medical Center in the US.

The two apps – Online Treatment Recovery Assistant for Concussion in Kids (OnTRACK) and BearGenes – were developed by students Hazza Daiban and Mohammad Al Mansoori during their eight-week internship in Washington, DC. The students worked under the guidance of Kevin Cleary, PhD, Professor of Radiology, Surgery, and Pediatrics at George Washington University and leader of the Bioengineering Initiative at the Sheikh Zayed Institute. OnTRACK was developed with Gerry Gioia, PhD, Director, Safe Concussion Program, while BearGenes was developed with Natasha Shur, MD, and Marshall Summar, MD, from the Children’s National Rare Disease Institute.

Dr. Arif Sultan Al Hammadi, Executive Vice-President, Khalifa University of Science and Technology, said: “Our students are offered various channels including internships to demonstrate their creativity and make use of their knowledge for the benefit of the community. The patient care apps developed by the two Khalifa University students illustrate the learning and expertise they have gained in Abu Dhabi and the guidance they received while interning at the Sheikh Zayed Institute in Washington DC. We believe institutions such as the SZI offer our students the right platform to not only widen their knowledge horizon but also serve as an instrument to sharpen their skills in areas including healthcare.”

The OnTRACK mobile app prototype that Daiban worked on is intended to help in concussion management by using ecological momentary assessment (EMA) of symptoms and to prompt patient treatment strategies. It is designed to provide support for patients five years and older who are identified with concussion. The developers are keen to incorporate the feedback currently being received from end users.

The BearGenes mobile app prototype that Al Mansoori worked on is designed to provide a trusted educational and informative platform for the patients and the public about genetic counseling and genetic conditions. It also provides information on where to access genetic expertise, such as the Children’s National Rare Disease Institute. The team is planning to create a web version of the platform that will be linked with the mobile app. Videos and information are being created by Children’s National Rare Disease Institute and will be added to the mobile app prototype database. Once uploaded to Play Store and App Store, mobile devices with the app will be offered to interested patient families.

Research professor and engineer Dr. Kevin Cleary said: “It was a great pleasure to have Hazza and Mohammad as interns. They made a positive contribution to our institute and hospital and did an excellent job developing the prototype apps.”

Dr. Cleary leads SZI’s interdisciplinary bioengineering team and focuses on technology development for pediatric medicine, working with the clinical team and other colleagues at Children’s National.

In addition to creating the Sheikh Zayed Institute for Pediatric Surgical Innovation, the Children’s National Medical Center has also named its primary campus in downtown Washington DC, the Sheikh Zayed Campus for Advanced Pediatric Medicine.

Improved Switching Algorithm Helps Balance High-Voltage Power Converter

Modular Multi-Level Converter Can Provide Greater Efficiency in Wind, Solar, Oil and Gas, and EV Applications

A Khalifa University research team has developed a new switching algorithm for modular multi-level converters (MMC) — a promising electrical power system that has the potential to benefit the clean energy and oil and gas sectors.

The team, led by Associate Professor Dr. Abdul Rahman Balanthi Beig with graduate students Safia Babikir Bashir and Yan Yan, have developed a new switching algorithm to improve the performance of MMC. They recently published a paper in the international journal ‘Electrical Power and Energy Systems’ on their research. The MMC is expected to facilitate major changes in the way next-generation power systems are connected and operated.

“With the emergence of multi-level converters, the whole concept of the way electricity is generated, transmitted and consumed is changing. Today efficiency is the key objective in the electrical energy sector. The more energy mankind requires, the more scientists and engineers have been tasked with the challenge of transferring power over long distances and connecting various types of power systems and grids in the most effective and efficient manner possible, to reduce losses and cost. The MMC has potential to solve some of these challenges, but itself had some unresolved issues that we have attempted to address to increase its voltage balancing and overall reliability,” Dr. Beig explained.

An MMC is a type of multi-level voltage-source converter that can convert electric power from high voltage direct current (HVDC) to high voltage alternating current (HVAC), and vice versa. The modularity of the MMC makes them relevant to many functions and industries that can benefit from their ability to control a voltage source without an isolated direct current (DC) bus voltage, which eliminates the need of an additional isolation transformer, making the system more compact, economical and efficient. MMCs are now the most rapidly growing type of voltage source converters and are used in medium voltage applications, like integrating wind generators or large solar plants to electrical grids.

Dispatching electrical energy in direct current (DC) form is economical and efficient when large amounts of power, approximately a few megawatts, is transferred over a long distance at very high voltages of about 600kV to 1600kV. This technology is known as High Voltage Direct Current (HVDC) transmission. HVDC was not sufficiently reliable, efficient and simple to operate until the multi-level voltage source converter (ML-VSC) system was invented in the early 21st century. With this enabling technology, the electric power generated from sources such as large photovoltaic farms and wind farms can be integrated easily into HVDC networks.

In comparison, the AC form of power is economical when a few hundred kilowatts of power is distributed to several consumers in an industrial or residential area, and when that power is distributed at different voltage levels. So with MMC, the existing vast AC network is still useful, as ML-VSC links the electrical energy from HVDC to AC networks. The ML-VSC can also transfer power from an AC network to a DC network and vice versa.

Multi-level converters based on the MMC configuration also offer modularity, which makes them the very attractive from the manufacturing and operational point of view. An MMC is a stack of several identical single phase converter units. The manufacturing industry has the advantage of repeatability where one type of small converter (known as a cell) is manufactured in a large number, allowing parallel production line.

In spite of the many MMC advantages, technicians have found some limitations due to differences in voltage across the cells and large circulation current in the converter power circuit due to this imbalance. This degrades the converter efficiency. Therefore, the Power Electronics and Sustainable Energy (PEASE) lab research team at KU has developed a new switching algorithm for MMC, which results in less cell voltage variation, thus reduced circulation current.

“We are working on developing a new switching algorithm that will eventually improve the performance of MMC and also working on optimizing the size of capacitor and arm inductors that are essential components of MMC. Another area of research is developing new control algorithms to connect these inverters between HVDC and AC networks,” Dr. Beig explained.

The team demonstrated the successful use of their algorithm to a MMC-based DC-to-AC converter connected to different types of AC grids. This work is published as a paper in the international journal ‘Electrical Power and Energy Systems’. The team is currently in the process of demonstrating the successful use of their algorithm for a MMC-based AC-to-DC converter and published their initial work in the IEEE Industry Applications Annual meeting and Conference (IEEE-IAS 2018) at Portland USA, which took place Sept 21-27, 2018.

Electrical engineering graduate students contributed to the project with the support from PEASE Lab engineer Saikrishna Kanukollu. Currently the team headed by Dr. Beig and electrical engineering graduate student Yan Yan has developed an experimental prototype of MMC. The next step is to develop another similar prototype and demonstrate the power transfer between two AC networks through and HVDC link.

Now Dr. Beig and other researchers at the PEASE lab are working on further developing the findings from the project and other related applications at Khalifa University’s newly launched Advanced Power and Energy Center.

“New MMC applications being developed include compact substations using power electronic transformers. One of the challenges is to keep these converters in operation without going out of control when large changes in the AC network takes place,” Dr. Beig explained.

Dr. Beig is also working with Professor Dr. Igor Boiko to develop self-tuning algorithms for these converters so that the converters continue to have stable operation under such conditions.

“This project has great promise for industry applications and further development. If the identified problems with MMC are addressed, then MMC based regenerative drives will become very popular and find applications in heavy industries like oil and gas, all electric ships and all electric aircraft, in addition to the renewable energy systems,” Dr. Beig concluded.
