si New Carrier Fluid Makes Hydrogen Way Easier to Transport By spectrum.ieee.org Published On :: Thu, 31 Oct 2024 12:00:03 +0000 Imagine pulling up to a refueling station and filling your vehicle’s tank with liquid hydrogen, as safe and convenient to handle as gasoline or diesel, without the need for high-pressure tanks or cryogenic storage. This vision of a sustainable future could become a reality if a Calgary, Canada–based company, Ayrton Energy, can scale up its innovative method of hydrogen storage and distribution. Ayrton’s technology could make hydrogen a viable, one-to-one replacement for fossil fuels in existing infrastructure like pipelines, fuel tankers, rail cars, and trucks.The company’s approach is to use liquid organic hydrogen carriers (LOHCs) to make it easier to transport and store hydrogen. The method chemically bonds hydrogen to carrier molecules, which absorb hydrogen molecules and make them more stable—kind of like hydrogenating cooking oil to produce margarine. A researcher pours a sample of Ayrton’s LOHC fluid into a vial.Ayrton EnergyThe approach would allow liquid hydrogen to be transported and stored in ambient conditions, rather than in the high-pressure, cryogenic tanks (to hold it at temperatures below -252 ºC) currently required for keeping hydrogen in liquid form. It would also be a big improvement on gaseous hydrogen, which is highly volatile and difficult to keep contained.Founded in 2021, Ayrton is one of several companies across the globe developing LOHCs, including Japan’s Chiyoda and Mitsubishi, Germany’s Covalion, and China’s Hynertech. But toxicity, energy density, and input energy issues have limited LOHCs as contenders for making liquid hydrogen feasible. Ayrton says its formulation eliminates these trade-offs.Safe, Efficient Hydrogen Fuel for VehiclesConventional LOHC technologies used by most of the aforementioned companies rely on substances such as toluene, which forms methylcyclohexane when hydrogenated. These carriers pose safety risks due to their flammability and volatility. Hydrogenious LOHC Technologies in Erlanger, Germany and other hydrogen fuel companies have shifted toward dibenzyltoluene, a more stable carrier that holds more hydrogen per unit volume than methylcyclohexane, though it requires higher temperatures (and thus more energy) to bind and release the hydrogen. Dibenzyltoluene hydrogenation occurs at between 3 and 10 megapascals (30 and 100 bar) and 200–300 ºC, compared with 10 MPa (100 bar), and just under 200 ºC for methylcyclohexane.Ayrton’s proprietary oil-based hydrogen carrier not only captures and releases hydrogen with less input energy than is required for other LOHCs, but also stores more hydrogen than methylcyclohexane can—55 kilograms per cubic meter compared with methylcyclohexane’s 50 kg/m³. Dibenzyltoluene holds more hydrogen per unit volume (up to 65 kg/m³), but Ayrton’s approach to infusing the carrier with hydrogen atoms promises to cost less. Hydrogenation or dehydrogenation with Ayrton’s carrier fluid occurs at 0.1 megapascal (1 bar) and about 100 ºC, says founder and CEO Natasha Kostenuk. And as with the other LOHCs, after hydrogenation it can be transported and stored at ambient temperatures and pressures.Judges described [Ayrton's approach] as a critical technology for the deployment of hydrogen at large scale.” —Katie Richardson, National Renewable Energy LabAyrton’s LOHC fluid is as safe to handle as margarine, but it’s still a chemical, says Kostenuk. “I wouldn’t drink it. If you did, you wouldn’t feel very good. But it’s not lethal,” she says.Kostenuk and fellow Ayrton cofounder Brandy Kinkead (who serves as the company’s chief technical officer) were originally trying to bring hydrogen generators to market to fill gaps in the electrical grid. “We were looking for fuel cells and hydrogen storage. Fuel cells were easy to find, but we couldn’t find a hydrogen storage method or medium that would be safe and easy to transport to fuel our vision of what we were trying to do with hydrogen generators,” Kostenuk says. During the search, they came across LOHC technology but weren’t satisfied with the trade-offs demanded by existing liquid hydrogen carriers. “We had the idea that we could do it better,” she says. The duo pivoted, adjusting their focus from hydrogen generators to hydrogen storage solutions.“Everybody gets excited about hydrogen production and hydrogen end use, but they forget that you have to store and manage the hydrogen,” Kostenuk says. Incompatibility with current storage and distribution has been a barrier to adoption, she says. “We’re really excited about being able to reuse existing infrastructure that’s in place all over the world.” Ayrton’s hydrogenated liquid has fuel-cell-grade (99.999 percent) hydrogen purity, so there’s no advantage in using pure liquid hydrogen with its need for subzero temperatures, according to the company.The main challenge the company faces is the set of issues that come along with any technology scaling up from pilot-stage production to commercial manufacturing, says Kostenuk. “A crucial part of that is aligning ourselves with the right manufacturing partners along the way,” she notes.Asked about how Ayrton is dealing with some other challenges common to LOHCs, Kostenuk says Ayrton has managed to sidestep them. “We stayed away from materials that are expensive and hard to procure, which will help us avoid any supply chain issues,” she says. By performing the reactions at such low temperatures, Ayrton can get its carrier fluid to withstand 1,000 hydrogenation-dehydrogenation cycles before it no longer holds enough hydrogen to be useful. Conventional LOHCs are limited to a couple of hundred cycles before the high temperatures required for bonding and releasing the hydrogen breaks down the fluid and diminishes its storage capacity, Kostenuk says.Breakthrough in Hydrogen Storage TechnologyIn acknowledgement of what Ayrton’s nontoxic, oil-based carrier fluid could mean for the energy and transportation sectors, the U.S. National Renewable Energy Lab (NREL) at its annual Industry Growth Forum in May named Ayrton an “outstanding early-stage venture.” A selection committee of more than 180 climate tech and cleantech investors and industry experts chose Ayrton from a pool of more than 200 initial applicants, says Katie Richardson, group manager of NREL’s Innovation and Entrepreneurship Center, which organized the forum. The committee based its decision on the company’s innovation, market positioning, business model, team, next steps for funding, technology, capital use, and quality of pitch presentation. “Judges described Ayrton’s approach as a critical technology for the deployment of hydrogen at large scale,” Richardson says.As a next step toward enabling hydrogen to push gasoline and diesel aside, “we’re talking with hydrogen producers who are right now offering their customers cryogenic and compressed hydrogen,” says Kostenuk. “If they offered LOHC, it would enable them to deliver across longer distances, in larger volumes, in a multimodal way.” The company is also talking to some industrial site owners who could use the hydrogenated LOHC for buffer storage to hold onto some of the energy they’re getting from clean, intermittent sources like solar and wind. Another natural fit, she says, is energy service providers that are looking for a reliable method of seasonal storage beyond what batteries can offer. The goal is to eventually scale up enough to become the go-to alternative (or perhaps the standard) fuel for cars, trucks, trains, and ships.

si Wireless Signals That Predict Flash Floods By spectrum.ieee.org Published On :: Mon, 04 Nov 2024 19:00:04 +0000 Like many innovators, Hagit Messer-Yaron had a life-changing idea while doing something mundane: Talking with a colleague over a cup of coffee. The IEEE Life Fellow, who in 2006 was head of Tel Aviv University’s Porter School of Environmental Studies, was at the school’s cafeteria with a meteorological researcher. He shared his struggles with finding high-resolution weather data for his climate models, which are used to forecast and track flash floods.Predicting floods is crucial for quickly evacuating residents in affected areas and protecting homes and businesses against damage.Hagit Messer-YaronEmployer Tel Aviv UniversityTitle Professor emeritaMember grade Life FellowAlma mater Tel Aviv UniversityHer colleague “said researchers in the field had limited measurements because the equipment meteorologists used to collect weather data—including radar satellites—is expensive to purchase and maintain, especially in developing countries,” Messer-Yaron says.Because of that, she says, high-resolution data about temperature, air quality, wind speed, and precipitation levels is often inconsistent—which is a problem when trying to produce accurate models and predictions.An expert in signal processing and cellular communication, Messer-Yaron came up with the idea of using existing wireless communication signals to collect weather data, as communication networks are spread across the globe.In 2006 she and her research team developed algorithms that process and analyze data collected by communication networks to monitor rainfall. They measure the difference in amplitude of the signals transmitted and received by the systems to extract data needed to predict flash floods.The method was first demonstrated in Israel. Messer-Yaron is working to integrate it into communication networks worldwide.For her work, she received this year’s IEEE Medal for Environmental and Safety Technologies for “contributions to sensing of the environment using wireless communication networks.” The award is sponsored by Toyota.“Receiving an IEEE medal, which is the highest-level award you can get within the organization, was really a surprise, and I was extremely happy to [receive] it,” she says. “I was proud that IEEE was able to evaluate and see the potential in our technology for public good and to reward it.”A passion for teachingGrowing up in Israel, Messer-Yaron was interested in art, literature, and science. When it came time to choose a career, she found it difficult to decide, she says. Ultimately, she chose electrical engineering, figuring it would be easier to enjoy art and literature as hobbies.After completing her mandatory service in the Israel Defense Forces in 1973, she began her undergraduate studies at Tel Aviv University, where she found her passion: Signal processing.“Electrical engineering is a very broad topic,” she says. “As an undergrad, you learn all the parts that make up electrical engineering, including applied physics and applied mathematics. I really enjoyed applied mathematics and soon discovered signal processing. I found it quite amazing how, by using algorithms, you can direct signals to extract information.”She graduated with a bachelor’s degree in EE in 1977 and continued her education there, earning master’s and doctoral degrees in 1979 and 1984. She moved to the United States for a postdoctoral position at Yale. There she worked with IEEE Life Fellow Peter Schultheiss, who was known for his research in using sensor array systems in underwater acoustics.Inspired by Schultheiss’s passion for teaching, Messer-Yaron decided to pursue a career in academia. She was hired by Tel Aviv University as an electrical engineering professor in 1986. She was the first woman in Israel to become a full professor in the subject.“Being a faculty member at a public university is the best job you can do. I didn’t make a lot of money, but at the end of each day, I looked back at what I did [with pride].”For the next 14 years, she conducted research in statistical signal processing, time-delay estimation, and sensor array processing.Her passion for teaching took her around the world as a visiting professor at Yale, the New Jersey Institute of Technology, the Institut Polytechnique de Paris, and other schools. She collaborated with colleagues from the universities on research projects.In 1999 she was promoted to director of Tel Aviv University’s undergraduate electrical engineering program. A year later, she was offered an opportunity she couldn’t refuse: Serving as chief scientist for the Israeli Ministry of Science, Culture, and Sports. She took a sabbatical from teaching and for the next three years oversaw the country’s science policy.“I believe [working in the public sector] is part of our duty as faculty members, especially in public universities, because that makes you a public intellectual,” she says. “Working for the government gave me a broad view of many things that you don’t see as a professor, even in a large university.”When she returned to the university in 2004, Messer-Yaron was appointed as the director of the new school of environmental studies. She oversaw the allocation of research funding and spoke with researchers individually to better understand their needs. After having coffee with one researcher, she realized there was a need to develop better weather-monitoring technology. Hagit Messer-Yaron proudly displays her IEEE Medal for Environmental and Safety Technologies at this year’s IEEE Honors Ceremony. She is accompanied by IEEE President-Elect Kathleen Kramer and IEEE President Tom Couglin.Robb CohenUsing signal processing to monitor weatherBecause the planet is warming, the risk of flash floods is steadily increasing. Warmer air holds more water—which leads to heavier-than-usual rainfall and results in more flooding, according to the U.S. Environmental Protection Agency. Data about rainfall is typically collected by satellite radar and ground-based rain gauges. However, radar images don’t provide researchers with precise readings of what’s happening on the ground, according to an Ensia article. Rain gauges are accurate but provide data from small areas only.So Messer-Yaron set her sights on developing technology that connects to cellular networks close to the ground to provide more accurate measurements, she says. Using existing infrastructure eliminates the need to build new weather radars and weather stations.Communication systems automatically record the transmitted signal level and the received signal level, but rain can alter otherwise smooth wave patterns. By measuring the difference in the amplitude, meteorologists could extract the data necessary to track rainfall using the signal processing algorithms.In 2005 Messer-Yaron and her group successfully tested the technology. The following year, their “Environmental Monitoring by Wireless Communication Networks” paper was published in Science.The algorithm is being used in Israel in partnership with all three of the country’s major cellular service providers. Messer-Yaron acknowledges, however, that negotiating deals with cellular service companies in other countries has been difficult.To expand the technology’s use worldwide, Messer-Yaron launched a research network through the European Cooperation in Science and Technology (COST), called an opportunistic precipitation sensing network known as OPENSENSE. The group connects researchers, meteorologists, and other experts around the world to collaborate on integrating the technology in members’ communities.Monitoring the effects of climate changeSince developing the technology, Messer-Yaron has held a number of jobs including president of the Open University of Israel and vice chair of the country’s Council for Higher Education, which accredits academic institutions.She is maintaining her link with Tel Aviv University today as a professor emerita.“Being a faculty member at a public university is the best job you can do,” she says. “I didn’t make a lot of money, but at the end of each day, I looked back at what I did [with pride]. Because of the academic freedom and the autonomy I had, I was able to do many things in addition to teaching, including research.” To continue her work in developing technology to monitor weather events, in 2016, she helped found ClimaCell, now Tomorrow.io, based in Boston. The startup aims to use wireless communication infrastructure and IoT devices to collect real-time weather data. Messer-Yaron served as its chief scientist until 2017.She continues to update the original algorithms with her students, most recently with machine learning capabilities to extract data from physical measurements of the signal level in communication networks.A global engineering communityWhen Messer-Yaron was an undergraduate student, she joined IEEE at the suggestion of one of her professors. “I didn’t think much about the benefits of being a member until I became a graduate student,” she says. “I started attending conferences and publishing papers in IEEE journals, and the organization became my professional community.”She is an active volunteer and a member of the IEEE Signal Processing Society. From 1994 to 2010 she served on the society’s Signal Processing Theory and Methods technical committee. She was associate editor of IEEE Signal Processing Letters and IEEE Transactions on Signal Processing. She is a member of the editorial boards of the IEEE Journal of Selected Topics in Signal Processing and IEEE Transactions on Signal Processing.In the past 10 years, she’s been involved with other IEEE committees including the conduct review, ethics and member conduct, and global public policy bodies.“I don’t see my career or my professional life without the IEEE,” she says Full Article Climate change Climate tech Ieee awards Ieee member news Signal processing Type:ti
si U.S. Chip Revival Plan Chooses Sites By spectrum.ieee.org Published On :: Tue, 05 Nov 2024 18:51:46 +0000 Last week the organization tasked with running the the biggest chunk of U.S. CHIPS Act’s US $13 billion R&D program made some significant strides: The National Semiconductor Technology Center (NSTC) released a strategic plan and selected the sites of two of three planned facilities and released a new strategic plan. The locations of the two sites—a “design and collaboration” center in Sunnyvale, Calif., and a lab devoted to advancing the leading edge of chipmaking, in Albany, N.Y.—build on an existing ecosystem at each location, experts say. The location of the third planned center—a chip prototyping and packaging site that could be especially critical for speeding semiconductor startups—is still a matter of speculation. “The NSTC represents a once-in-a-generation opportunity for the U.S. to accelerate the pace of innovation in semiconductor technology,” Deirdre Hanford, CEO of Natcast, the nonprofit that runs the NSTC centers, said in a statement. According to the strategic plan, which covers 2025 to 2027, the NSTC is meant to accomplish three goals: extend U.S. technology leadership, reduce the time and cost to prototype, and build and sustain a semiconductor workforce development ecosystem. The three centers are meant to do a mix of all three. New York gets extreme ultraviolet lithography NSTC plans to direct $825 million into the Albany project. The site will be dedicated to extreme ultraviolet lithography, a technology that’s essential to making the most advanced logic chips. The Albany Nanotech Complex, which has already seen more than $25 billion in investments from the state and industry partners over two decades, will form the heart of the future NSTC center. It already has an EUV lithography machine on site and has begun an expansion to install a next-generation version, called high-NA EUV, which promises to produce even finer chip features. Working with a tool recently installed in Europe, IBM, a long-time tenant of the Albany research facility, reported record yields of copper interconnects built every 21 nanometers, a pitch several nanometers tighter than possible with ordinary EUV. “It’s fulfilling to see that this ecosystem can be taken to the national and global level through CHIPS Act funding,” said Mukesh Khare, general manager of IBM’s semiconductors division, speaking from the future site of the NSTC EUV center. “It’s the right time, and we have all the ingredients.” While only a few companies are capable of manufacturing cutting edge logic using EUV, the impact of the NSTC center will be much broader, Khare argues. It will extend down as far as early-stage startups with ideas or materials for improving the chipmaking process “An EUV R&D center doesn’t mean just one machine,” says Khare. “It needs so many machines around it… It’s a very large ecosystem.” Silicon Valley lands the design center The design center is tasked with conducting advanced research in chip design, electronic design automation (EDA), chip and system architectures, and hardware security. It will also host the NSTC’s design enablement gateway—a program that provides NSTC members with a secure, cloud-based access to design tools, reference processes and designs, and shared data sets, with the goal of reducing the time and cost of design. Additionally, it will house workforce development, member convening, and administration functions. Situating the design center in Silicon Valley, with its concentration of research universities, venture capital, and workforce, seems like the obvious choice to many experts. “I can’t think of a better place,” says Patrick Soheili, co-founder of interconnect technology startup Eliyan, which is based in Santa Clara, Calif. Abhijeet Chakraborty, vice president of engineering in the technology and product group at Silicon Valley-based Synopsys, a leading maker of EDA software, sees Silicon Valley’s expansive tech ecosystem as one of its main advantages in landing the NSTC’s design center. The region concentrates companies and researchers involved in the whole spectrum of the industry from semiconductor process technology to cloud software. Access to such a broad range of industries is increasingly important for chip design startups, he says. “To design a chip or component these days you need to go from concept to design to validation in an environment that takes care of the entire stack,” he says. It’s prohibitively expensive for a startup to do that alone, so one of Chakraborty’s hopes for the design center is that it will help startups access the design kits and other data needed to operate in this new environment. Packaging and prototyping still to come A third promised center for prototyping and packaging is still to come. “The big question is where does the packaging and prototyping go?” says Mark Granahan, cofounder and CEO of Pennsylvania-based power semiconductor startup Ideal Semiconductor. “To me that’s a great opportunity.” He points out that because there is so little packaging technology infrastructure in the United States, any ambitious state or region should have a shot at hosting such a center. One of the original intentions of the act, after all, was to expand the number of regions of the country that are involved in the semiconductor industry. But that hasn’t stopped some already tech-heavy regions from wanting it. “Oregon offers the strongest ecosystem for such a facility,” a spokesperson for Intel, whose technology development is done there. “The state is uniquely positioned to contribute to the success of the NSTC and help drive technological advancements in the U.S. semiconductor industry.” As NSTC makes progress, Granahan’s concern is that bureaucracy will expand with it and slow efforts to boost the U.S. chip industry. Already the layers of control are multiplying. The Chips Office at the National Institute of Standards and Technology executes the Act. The NSTC is administered by the nonprofit Natcast, which directs the EUV center, which is in a facility run by another nonprofit, NY CREATES. “We want these things to be agile and make local decisions.” Full Article Chips act Euv Chip design Semiconductors
si Millimeter Waves May Not Be 6G’s Most Promising Spectrum By spectrum.ieee.org Published On :: Wed, 06 Nov 2024 17:00:04 +0000 In 6G telecom research today, a crucial portion of wireless spectrum has been neglected: the Frequency Range 3, or FR3, band. The shortcoming is partly due to a lack of viable software and hardware platforms for studying this region of spectrum, ranging from approximately 6 to 24 gigahertz. But a new, open-source wireless research kit is changing that equation. And research conducted using that kit, presented last week at a leading industry conference, offers proof of viability of this spectrum band for future 6G networks.In fact, it’s also arguably signaling a moment of telecom industry re-evaluation. The high-bandwidth 6G future, according to these folks, may not be entirely centered around difficult millimeter wave-based technologies. Instead, 6G may leave plenty of room for higher-bandwidth microwave spectrum tech that is ultimately more familiar and accessible.The FR3 band is a region of microwave spectrum just shy of millimeter-wave frequencies (30 to 300 GHz). FR3 is also already very popular today for satellite Internet and military communications. For future 5G and 6G networks to share the FR3 band with incumbent players would require telecom networks nimble enough to perform regular, rapid-response spectrum-hopping.Yet spectrum-hopping might still be an easier problem to solve than those posed by the inherent physical shortcomings of some portions of millimeter-wave spectrum—shortcomings that include limited range, poor penetration, line-of-sight operations, higher power requirements, and susceptibility to weather. Pi-Radio’s New FaceEarlier this year, the Brooklyn, N.Y.-based startup Pi-Radio—a spinoff from New York University’s Tandon School of Engineering—released a wireless spectrum hardware and software kit for telecom research and development. Pi-Radio’s FR-3 is a software-defined radio system developed for the FR3 band specifically, says company co-founder Sundeep Rangan.“Software-defined radio is basically a programmable platform to experiment and build any type of wireless technology,” says Rangan, who is also the associate director of NYU Wireless. “In the early stages when developing systems, all researchers need these.”For instance, the Pi-Radio team presented one new research finding that infers direction to an FR3 antenna from measurements taken by a mobile Pi-Radio receiver—presented at the IEEE Signal Processing Society‘s Asilomar Conference on Signals, Systems and Computers in Pacific Grove, Calif. on 30 October. According to Pi-Radio co-founder Marco Mezzavilla, who’s also an associate professor at the Polytechnic University of Milan, the early-stage FR3 research that the team presented at Asilomar will enable researchers “to capture [signal] propagation in these frequencies and will allow us to characterize it, understand it, and model it... And this is the first stepping stone towards designing future wireless systems at these frequencies.”There’s a good reason researchers have recently rediscovered FR3, says Paolo Testolina, postdoctoral research fellow at Northeastern University’s Institute for the Wireless Internet of Things unaffiliated with the current research effort. “The current scarcity of spectrum for communications is driving operators and researchers to look in this band, where they believe it is possible to coexist with the current incumbents,” he says. “Spectrum sharing will be key in this band.”Rangan notes that the work on which Pi-Radio was built has been published earlier this year both on the more foundational aspects of building networks in the FR3 band as well as the specific implementation of Pi-Radio’s unique, frequency-hopping research platform for future wireless networks. (Both papers were published in IEEE journals.)“If you have frequency hopping, that means you can get systems that are resilient to blockage,” Rangan says. “But even, potentially, if it was attacked or compromised in any other way, this could actually open up a new type of dimension that we typically haven’t had in the cellular infrastructure.” The frequency-hopping that FR3 requires for wireless communications, in other words, could introduce a layer of hack-proofing that might potentially strengthen the overall network.Complement, Not ReplacementThe Pi-Radio team stresses, however, that FR3 would not supplant or supersede other new segments of wireless spectrum. There are, for instance, millimeter wave 5G deployments already underway today that will no doubt expand in scope and performance into the 6G future. That said, the ways that FR3 expand future 5G and 6G spectrum usage is an entirely unwritten chapter: Whether FR3 as a wireless spectrum band fizzles, or takes off, or finds a comfortable place somewhere in between depends in part on how it’s researched and developed now, the Pi-Radio team says. “We’re at this tipping point where researchers and academics actually are empowered by the combination of this cutting-edge hardware with open-source software,” Mezzavilla says. “And that will enable the testing of new features for communications in these new frequency bands.” (Mezzavilla credits the National Telecommunications and Information Administration for recognizing the potential of FR3, and for funding the group’s research.)By contrast, millimeter-wave 5G and 6G research has to date been bolstered, the team says, by the presence of a wide range of millimeter-wave software-defined radio (SDR) systems and other research platforms. “Companies like Qualcomm, Samsung, Nokia, they actually had excellent millimeter wave development platforms,” Rangan says. “But they were in-house. And the effort it took to build one—an SDR at a university lab—was sort of insurmountable.”So releasing an inexpensive open-source SDR in the FR3 band, Mezzavilla says, could jump start a whole new wave of 6G research. “This is just the starting point,” Mezzavilla says. “From now on we’re going to build new features—new reference signals, new radio resource control signals, near-field operations... We’re ready to ship these yellow boxes to other academics around the world to test new features and test them quickly, before 6G is even remotely near us.”This story was updated on 7 November 2024 to include detail about funding from the National Telecommunications and Information Administration.
