Hinetics

Three out of the 68 research and development projects nationwide aimed at developing disruptive technologies to strengthen the U.S. advanced energy enterprise were awarded to POETS faculty, including Professor Kiruba Haran.
Led by the Department of Energy’s Advanced Research Projects Agency-Energy, the OPEN 2021 program prioritizes funding high-impact, high-risk technologies that support novel approaches to clean energy challenges.
Professor Haran’s startup company, Hinetics, will lead an OPEN 2021 project, Cryogen-fRee Ultra-high fIeld Superconducting Electric (CRUISE) Motor, which was awarded $5.7 million. The company, alongside UIUC and POETS researchers, will develop and demonstrate a high-power density electric machine to enable electrified aircraft propulsion systems up to 10 MW and beyond. Hinetics’ technology uses a superconducting machine design that eliminates the need for cryogenic auxiliary systems yet maintains low total mass. The concept features a sub-20 K Stirling-cycle cooler integrated with a low-loss rotor, magnetic fields on an order of magnitude higher than conventional machines, and a novel coil suspension and torque transfer system with tensioned fibers that cut the cryogenic heat-load by a factor of 10 to eliminate the need for external coolers. This design could enable a 10 MW, 3000 RPM aircraft propulsion motor weighing less than 250 kilograms that rejects up to 10 times less total heat to the ambient environment—achieving more than 99% efficiency.

ECEB Lobby Energy Display: 0-Net Energy, Learning about Energy Efficiency, and Solar Phone Charger Drawing

Posted on by
Elaine is a Computer Science major who had a class in the Grainger Auditorium and stopped to interact with the energy kiosks and the large display screen depicting an ECEB energy efficiency. She chose to conserve heat and ac and turn off the lights and unplug appliances when not in use. Elaine walks or takes the bus to save energy for transportation to classes. She thought perhaps in the future we could run a contest for conserving energy.

The UIUC Student Sustainability Committee funded an energy display in the ECEB lobby to accomplish three goals. The first uses kiosks to teach students, faculty and campus visitors about energy use while presenting relatable and significant ways they can reduce energy-consumption patterns. The second is to show on a large screen energy being produced by the ECEB solar array, energy being used by ECEB, and ECEB’s allotment from Solar Farm 2 to reach zero net energy. The third is to demonstrate ECEB’s energy efficiencies and document its progress toward certification as the first zero-net energy building on campus.
To achieve the first goal, two touch-activated kiosks were installed and programmed identically for Engineering Open House 2021 https://ecebenergykiosk.web.illinois.edu/ by a Computer Science RSO headed by undergraduates Mitchell Bifeld and Smit Purohit. Kiosk visitors choose from several options and pledge to save energy. Their names are entered into random drawings twice a year: Energy Efficiency Day in October, and Earth Day in April. The first solar phone charger was awarded to Elaine Minghui Wang. Joyce Mast is handing her the charger.

Energy-saving choices. Other screens list UIUC classes on sustainability and ways to help save energy on campus, including Friday Night Lights Out.

Enough Power for EVs?

Posted on by

“With the rush to move to all electric vehicles, have the electric power generation companies been consulted? With all of the coal fired power plants being phased out, and no new nuclear plants coming online, will wind and solar be able to pick up the load? Worst case is we are building another bottle-neck that could raise utility rates for all of us, and make electric vehicles much more expensive.” Question from Tom’s Mailbag from the News-Gazette, February 4. 2021.


“It is a little hard to call it a ‘rush,’” said Phil Krein, a professor emeritus at the Grainger Center for Electric Machinery and Electromechanics at the University of Illinois. “The research community, transportation industry, and electric power industry have been engaged intensively on this issue over the past 25 years or so. Our regional utility, Ameren, is taking a leadership role.”
“In Illinois the growth in wind and solar electricity sources is far outpacing the growth in load from electric transportation,” Krein said. “The Federal Highway Administration’s 2016 Highway Statistics Report indicates about 10 million cars and trucks registered in Illinois. A transition of a few million of these to electrical energy is well within projected resource growth.”
“There’s plenty of generating capacity in Illinois and the Midwest to meet the demand,” he said. “And utility companies will incentivize consumers charging electric vehicles at times when power demand is lower.”
“Some will charge at night, some will charge at work. But the economic incentives will be such that it will tend to spread (demand) out,” said Krein. “They already have some of those rates in place.”
“A million (electric vehicles) is only 10 percent (of vehicles on the road in Illinois). It might get dicey when you get to 50 or 60 percent but by that time we should have our act together in many other ways as well. All the studies have shown that at 10 percent the impact on the grid is pretty minimal.”
“Illinois is better off than other states for a few reasons,” he said.
“Number one, despite their age and issues, we have a substantial nuclear power base. That’s a positive. Second is that although we don’t have the kind of wind resources that North Dakota or Nebraska have, we’ve got good wind resources and good solar resources. The other thing is that Illinois, in a sort of technical sense, is in the middle of the power grid and power flows through Illinois and we have really strong interconnections to resources. So when things go wrong we can be buying power from Tennessee and Indiana and Michigan and wherever.”

Illinois ECE Professor Alejandro Domínguez-García and Research Engineer Olaolu Ajala are part of a $25 million Department of Energy-funded consortium that is addressing the reliability challenges involved in integrating more solar and wind energy onto the nation’s electric grid.
The Universal Interoperability for Grid-Forming Inverters (UNIFI) consortium brings together leading researchers from more than 40 university, industry, and utility organizations to evaluate and design grid-forming inverter solutions that will enable the seamless integration of inverter-based renewable resources while ensuring the grid’s stability and reliability.
“What we aim to do is figure out how to operate the power grid with a very large amount of renewable-based generation instead of using fossil fuel generating units,” said Alejandro. “The technology we need to use to achieve that is very different from the technology we currently have in the grid for generating power.” Alejandro and Olaolu will apply their expertise in control algorithm design, modeling, and simulation, to ensure that a future renewable-based system operates reliably.
“You don’t have the luxury to [validate your designs] in a real power system because it is already in operation,” Olaolu added. Instead, the Illinois researchers will perform testing and validation of their algorithms in a hardware-in-the-loop emulation environment, a sophisticated simulation technique of a real system that has been used by the automotive and aircraft industries for years. They’ll also examine how to scale their emulation schemes to large-scale power grids.
UNIFI is led by the National Renewable Energy Lab, the University of Washington, and the Electric Power Research Institute.

Annabelle Epplin, the 2020 winner of The Grainger CEME Undergraduate Research and Leadership Award, and Joyce Mast, Coordinator for The Grainger Center for Electric Machinery and Electromechanics, demonstrated making s’mores with a solar oven while discussing the Electrical and Computer Engineering Building (ECEB)’s solar array.

ECEB has about 950 solar panels producing about 275 kilowatts of energy during peak usage. This is about one fifth of the building’s needs. Sixty panels (see arrow, center right, below) are dedicated to student and faculty research. Each panel can immediately convert energy produced into ready-to-use ac energy, directly connecting to the university’s power grid. ECEB’s panels comprise one of the largest ac solar installations of its kind and allow a 30% reduction in energy emissions, which is about 200,000 pounds of carbon dioxide per year. The solar panels figured strongly into ECEB’s achieving LEED Platinum certification.
