Dear Morgan

I hope that you are doing well!

I also hope that my request below are not presumptuous, but … 😊

1. From August I will be directing the College of Engineering Master’s program in Energy Systems. A you know, this is an interdepartmental program attracting students from across the board (electrical, civil, chemical, nuclear, mechanical, agricultural, computer, …). Part of the program expects students to work on real industry problems, either via an internship or by solving a client’s energy-related problems and communicating designs/solutions with clients. In Fall we have around 25 master’s students but that number will soon double.
   It will be a privilege if our students could perhaps work on F&S energy-related projects. I know that Rizwan Uddin and John Abelson previously had some students work on project for F&S, and for which our students managed to secure some SSC funds. I was hoping that would again be possible. Please can you indicate if you might have any immediate needs for our master’s students to assist F&S with any energy-related design/redesign work? It would be a privilege if they could benefit from such a “real-world” experience.
2. Andre Nel will again visit UIUC and he would love to again meet with you, please! He arrives here around noon on August 16 and leaves around 4 p.m. of the 17th. Is there perhaps any chance that he could again exchange ideas with you? Andre has brought about some interesting changes at the University of Johannesburg, including a 2-MW PV canopy located on parking areas. South Africa has immense electricity supply problems and you can imagine that running a campus with up to 11 hours of blackouts every day is exceedingly challenging. He has also purchased who-knows-how-many massive diesel generators to cope with blackouts. Totally unsustainable but it does the job for the time being.
   Please can you indicate if you might perhaps be able to meet for lunch at Houlihan’s on August 16th (around 1 p.m.)? Or, if you prefer, Andre could meet you at F&S or at iSEE. (I have also written to Madhu as Andre would like to also meet her.)   

Thank you in advance for your attention to my requests.
I look forward to hearing from you!

Kind regards
Leon

Hi Leon,

Thanks for reaching out and congrats on becoming the point person for the Masters of Energy Systems!

I'm adding Rob Roman here, so he can help connect your students with energy focused projects in Utilities and Energy Services (UES). Rob is the director of UES, and he is highly engaged with and supportive of the iCAP efforts.  Can you extend the lunch invite to him as well?

I will also pull together a few project ideas for your students. Can you remind me what the timeframe is for their projects?

For lunch, I'll need to reschedule something to be able to join you, so let me confirm next week.  It would be great to hear of the changes Andres has implemented and share some of our new projects as well. 

Thanks!

Morgan

Good afternoon Morgan, Rob

Thank you for your lightning-quick and positive response, and for introducing me to Rob! Rob, I look forward to collaborating with you.

• The “professional development” part of the M.Eng. (Energy Systems) degree comprises a 4-credit-hour project that can be taken in the Fall or Spring semester. (I believe that some students have also done this in summer, although UIUC faculty have to be available to act as advisors if that were to happen.) Students usually work alone on topics but they could also be given teamwork if the task demands that.

Where required, our students will also apply for SSC funding for your projects. But, as you know, our students are only here for a year (or perhaps 18 months) so there is only a slight chance that they might be able to participate in the projects for which they will be seeking SSC funding.

• I appreciate your positive response regarding potentially meeting with Andre! Apologies for the schlep regarding rescheduling your other appointment. Many thanks though for all your efforts. If you cannot reschedule that meeting, I think that Andre will have some time available on the 17th before his meeting with Karl Gnadt at the MTD --- Karl however must still confirm meeting times, etc. I therefore hope that you will indeed be able to accommodate Andre on the 16th, together with Madhu.

Looking forward to your further communication and wishing you the best
Leon

Hi Leon,

I hope you are well!  I’m looking at older emails, and I am worried I dropped the ball on this.  Are you still looking for something from me?

Thanks!

Morgan

Good morning Morgan

Great to hear from you 😊.

Thanks for your follow-up.
I attended one of Rob Roman’s meetings with his Assoc. Directors --- and they enthusiastically responded with some excellent project recommendations. I summarize the main suggestions below this email.

If you have any (additional) energy projects that you’d like to recommend for 2024, that would be super. Thank you in advance! I greatly appreciate your support and advice.

Best wishes,

Leon

SUMMARY OF SUGGESTION FROM ROB ROMAN’S TEAM:

1. Protection of our campus energy systems infrastructure from physical and cyber threats. Potential targets across campus include: Abbott Power Plant; electrical sub-stations, distribution center, and load centers; steam tunnels; high-pressure gas piping; domestic water piping system; chiller plants; storm sewer system; etc. We have had an increased frequency of malicious events across the country in recent times and this topic has been trending.
2. Promoting, marketing, and selling a campus approach to investing in retro-commissioning and control system modernization/optimization. The University of Illinois F&S teams in UES have saved millions of dollars over many years by dedicating staff and financial resources in these areas. This type of project could give students the opportunity to learn the value of a career path in technical sales and the types of companies that utilize these type of staff members. A focus on developing high-level communication skills and strategic sales skills in conjunction with engineering education can be a lucrative path for some students.     
3. Cost and Environmental Comparison of Fossil Fuels Cogen Plant with Renewable Energy Plant: This project would involve a comprehensive study of providing 100 MW of FIRM (24-7-365) from a plant fired by a fossil fuel fired co-gen plant as compared to a plant that is 100% renewable. I would recommend that for the cogen plant the project focus on a Gas Turbine/HRSG combination that is natural gas fired, and that for the renewable energy plant the project focus on solar/wind as the generation source with the storage required to provide the 24-7-365 reliability from 100 MW. The storage will likely need to be provided by batteries. Incentives/rebates can be considered and used to develop a “current cost” comparison, but I would recommend that a fully loaded cost be included so that there is an apples to apples comparison. Would recommend that the total carbon footprint of each project also be considered.
4. Chiller Plant Optimization: The University is in the process of developing an optimization model/system for the chilled water system. This model will monitor the system demand as well as the performance of the major pieces of equipment at each of the plants, and optimize the operation of the major pieces of equipment to increase the efficiency (lower the energy usage) of the overall system. This project would involve working with the contractor and controls engineer at UES to understand what does into developing the model, what are the keys aspects of optimizing the system/plants, and perhaps assisting with certain facets of the project. We would need to discuss this project with the company performing the optimization to insure they are agreeable to working with the students.
5. Solar Farm 2.0 Operator Project: The operator of Solar Farm 2.0 committed to partnering with the university on education as it relates to solar power. If a student were particularly interested in a solar power project, we could setup a conversation with Sol Systems to inquire if there was something in particular they would work with a master student on. They are helping with an undergraduate sustainability class, so I am assuming they would be interested in working with a masters student, but I don’t have a specific project in mind at this time.
6. Grid Reliability based on Increase Integration of Renewables into the Grid: Grid stability and reliability has been and will continue to be impacted significantly by the integration of more and more intermittent generation sources into the grid. This project would largely be research based to understand the nature of the issues that are being created, perhaps identifying the tipping point at which the % of intermittent resources will result in problems, and most importantly identify the steps that need to be taken to alleviate these issues.
7. Power Plant Projects: Mike Larson did not have anything specific in mind but would be willing to generate a suitable topic based on student interest in this area.
8. Study on Geothermal Use in Large Institutional Buildings at UIUC: We have investigated the use of geothermal on both large and smaller buildings on campus, and have not yet found compelling evidence the geothermal is a great option on our campus. This project would research the technology, it’s uses and applications, and the practicality of using it on our campus. The project could investigate large institutional projects that have included geothermal (Ball State and EPIC in Madison Wisconsin are two that come to mind), and assessing their viability on the UIUC campus.    
9. Protection of our campus energy systems infrastructure from physical and cyber threats. Potential targets across campus include: Abbott Power Plant; electrical sub-stations, distribution center, and load centers; steam tunnels; high-pressure gas piping; domestic water piping system; chiller plants; storm sewer system; etc. We have had an increased frequency of malicious events across the country in recent times and this topic has been trending.
10. Promoting, marketing, and selling a campus approach to investing in retro-commissioning and control system modernization/optimization. The University of Illinois F&S teams in UES have saved millions of dollars over many years by dedicating staff and financial resources in these areas. This type of project could give students the opportunity to learn the value of a career path in technical sales and the types of companies that utilize these type of staff members. A focus on developing high-level communication skills and strategic sales skills in conjunction with engineering education can be a lucrative path for some students.

Below is an email exchange between Jim Sims and Tom Keller:

Mike or Tom,

The EMT is discussing the advantages of converting building heating systems from steam to hot water with steam distribution. Would one of you be able to clarify this benefit?

Thanks,

Jim

---------------------------

Jim,

Hot water is more efficient than steam because it is easier to control. This also adds comfort to the occupants. Steam can be easier to leak and it is hotter, so there are some small safety concerns. Steam tends to be a bit noisier than hot water. Hot water can be easier to maintain than steam.

There are quite a few other reasons. This is why hot water heating systems have become the industry standard.

Thanks,

Tom

-----------------------------

EMT,

I asked Tom Keller and Mike Halm to provide some feedback regarding the advantages of hot water versus steam within buildings. Please see Tom Keller’s response below for our information. Please let me know if we would like for Tom would like to further explain “quite a few other reasons” or his primary benefits listed below.

Thanks,

Jim

Kane County Department of Environment and Water Resources, Management Coordinator, Ivy Klee reached out to get some information about solar panels. Specifically, they are proposing a solar project that is across some residential homes. The residents of those houses have growing concerns about living across from an eight acre solar field due to potential radiation. Ivy wants to know if this is a legitimate concern and if there is any research on this subject. Professor and Director at the Grainger Center of Electric Machinery and Electromechanics, Philip Klein, explained that any electromagnetic radiation stems from inverters and wiring, not from the panels themselves. Certified residential inverters must meet FCC Class B limits (similarly to air conditioners and other residential appliances). The only potential concern is communications interference which has only been an issue when solar farms have been installed very close to aircraft navigation radars or military radars. For more information visit: http://www.nrel.gov/docs/fy17osti/67440.pdf. 

Other information was shared regarding solar PV by Mechanical Engineering Emeritus Professor, Ty Newell:

-As homes electrify (heat pumps for comfort conditioning, heat pumps for water heating and heat pumps for clothes drying), along with EVs (Electric Vehicles), all solar energy (including wind) converted to electricity for powering our homes, buildings and vehicles is released back into the environment at exactly the same amount that was temporarily diverted to keep our food preserved, buildings comfortable, and providing transportation....unlike fossil (stored solar energy) that is an additional release of energy to the environment (along with a lot of other stuff)

-Every dollar removed from fossil fuel related electricity production creates 10 times more jobs in manufacturing and construction for building heat pumps, constructing solar and wind fields, and improving our buildings (~0.2to 0.3jobs per million$ of revenue for fossil fuel industry, similar to investment banks and health insurance companies versus 2-4jobs per million$ of revenue for jobs in manufacturing and construction...Fortune 500 data)

-Improving home and building efficiency will create a surplus of electric energy for a seamless transition to EV transportation

-EVs require about 200square feet of solar array (size of a garage car space) for 10-12,000 miles of driving per year

-The coal industry employs fewer people (less than 8000) in Illinois than the Univ of Illinois graduate each year.....clean energy and sustainable living technologies will provide those jobs

Description:

The 2015 iCAP, chapter 3, objective 3, is "Expand the purchase of clean energy. By FY20, obtain at least 120,000 MWh, and by FY25 at least 140,000 MWh from low-carbon energy sources. These targets represent 48% and 56% of our expected 2050 electricity demand, respectively." There are several methods for increasing campus clean energy use: on-campus renewable energy generation (such as the Solar Farm), off-campus power purchase agreements (such as the Wind PPA), the purchase of Renewable Energy Certifications (such as the FY15 RECs purchase), and clean energy provided through the grid purchased electricity (see MISO).

Background: 

Generate Renewable Energy On-Campus

Renewable energy on campus is one of the most important clean energy sources. Solar farm is the main project, geothermal is a promising method, combined with biomass, etc., the proportion of renewable energy is increasing.

Enter into Power Purchase Agreements

A power purchase agreement (PPA) is a contract with an energy generation facility. A long-term PPA with a renewable energy generation facility could enable the construction of new renewable energy generation. At the time of this writing, the most economical renewable PPAs are for wind energy from large farms of wind turbines, but we expect that other types of renewable PPAs may become affordable in the future.

Although nuclear power is not considered renewable, an existing nuclear power plant produces no carbon dioxide emissions and can help us meet our emissions goals. A PPA with a nuclear power plant would enable us to purchase energy from a zero-carbon source.

Buy Renewable Energy Certificates

Electrical output from both renewable and nonrenewable power sources are combined in a regionaltransmission grid. In order for a consumer to claim the use of renewable energy, it must own the associated Renewable Energy Certificates (RECs), each of which represents the environmental attributes of 1 MWh of renewable electricity generation.

Only the owners of RECs can claim that they are using renewable energy. For example, if a wind farm operator sells its electricity to one party but sells the associated RECs to a second party, only the second party can claim to be using green energy. To qualify as renewable, any energy the campus purchases must be bundled with RECs, and the campus must retain the RECs for any renewable energy it produces. Therefore, the forthcoming Solar Farm will count toward our renewable energy goals only so long as campus does not sell the associated RECs.

Another method to increase our use of renewable energy is to separately purchase “unbundled” RECs, without purchasing power from the same generation source. For example, we could purchase power from a coal plant, but purchase a corresponding number of RECs from a wind farm (in this case, the wind farm would sell its electricity without the environmental attributes to a customer who is not willing to pay for the environmental attributes). The purchase of unbundled RECs reduces our carbon footprint according to generally accepted carbon accounting procedures, but it is not clear if it adds renewable energy to the grid.

In 2015, there was exceptionally low demand for RECs in our local grid region because there are no effective government standards requiring the purchase of renewable electricity. At the same time, a significant number of wind farms have been built and are profitable even without selling RECs (due in large part to a federal tax credit for wind production), leading to a very large supply of RECs. Given the low demand and the oversupply, prices for RECs are very low, and therefore it is not clear that the purchase of RECs really provides an incentive for generators to produce more renewable electricity, or that it leads to an actual reduction in overall global CO2 emissions.

When unbundled RECs are purchased as part of a long-term contract, this can facilitate the construction of new renewable energy generation facilities. Long-term RECs contracts would also have the economic advantage of “locking in” the current low prices. Conversely, the voluntary purchase of short-term unbundled RECs from existing facilities does not add new renewable energy to the grid. For these reasons, the campus would have a greater environmental impact by purchasing long-term RECs contracts, either bundled with renewable energy in a PPA, or unbundled.

Low-Carbon Grid Purchased Electricity

Approximately half of the campus electrical demand is purchased through the MISO grid.  In FY15, the grid purchased electricity included over 10% from low-carbon sources.  Because the RECs are not included when campus buys the energy, it is unclear who can claim the use of that clean energy.  With the new energy bill passed in 2017, there are changes to the requirements for campus’ participation in the Renewable Portfolio Standard.  As these requirements and associated benefits of low-carbon energy in the grid become clarified, it may be determined that the grid’s clean energy can be included in the total campus clean energy usage.
