The only cryogenic hydrogen research laboratory in US academia.
Innovating electrofuels since 2010.
Imagine the challenge of storing and reliably dispensing fuel at -421°F, the temperature of liquid hydrogen. Go one step further — try it in microgravity. Not hard enough? If a vapor bubble leaves the bottom of the tank you’ll explode the turbo of your engine.
One of the greatest issues in developing a sustainable hydrogen economy is the issue of infrastructure. This project found that tube geometry can help cool gases, requiring less energy to keep fuel at cryogenic temperatures.
The first liquid hydrogen fueled drone by a University. Fourteen flights proved the airframe, electric propulsion, and guidance systems were working beautifully, and extensive ground testing and characterization of the hydrogen systems showed the fuel cell hydrogen powertrain was up to the task.
Join the CHARGE! — The Consortium for Hydrogen and Renewably Generated Electrofuels at WSU
I’m all charged up this morning about CHARGE — Washington State University’s (WSU’s) new Consortium for Hydrogen and Renewably Generated Electrofuels.
What is an electrofuel?
A high-value, storable, energy product created from hydrogen generated by renewable means like electricity, wind, or solar power. With no fossil fuel resources in the state, Washington has the potential to use electrofuels to eliminate carbon emissions across multiple sectors:
A couple of years ago I looked around the country for a center specifically devoted towards hydrogen and electrofuels — … » More …Read Story
Living hinges can be really cool
This is a preprint of my February column “Cool Fuel” in Cold Facts Magazine by the Cryogenic Society of America.
In the June issue of ColdFacts (V. 36, No. 3 2020) I talked about how we’re learning to be more flexible while keeping our cool (a nod to the pandemic). The fun take away though was the realization that thin film polymer origami bellows could flex 100’s of times immersed in liquid nitrogen without fracturing – my new favorite liquid nitrogen (LN2) demonstration. But it didn’t last long (as my favorite demo that is) due to Francis Dunne, a new PhD student in … » More …Read Story
How to Build a Cryogenic Plumbing Manifold
Plumbing manifolds on a cryogenic system are just as essential for functionality as proper electrical wiring from a simple light switch to an overhead light. Just like a wire sends current from point A to point B, a plumbing manifold can send hydrogen, helium, nitrogen, and other gasses from point A to B. The number of complex functions performed by plumbing manifolds leads to complexity that approaches integrated circuit boards. However, much less information, not to mention engineering standards, are available on how to reliably construct custom plumbing manifolds for research purposes. This post overviews the systems we have developed at HYPER for academic research … » More …Read Story
Why liquid hydrogen?
I’m continually surprised that the HYPER lab remains the only cryogenic hydrogen research lab in US academia. But then again, I find myself continually having to fight for liquid hydrogen, even to hydrogen experts. Hydrogen liquefies at atmospheric pressure only after cooling below 20 K (-420°F), you cannot liquefy hydrogen by increasing pressure. This requirement to make something that cold (a.k.a. cryogenics) is technically challenging. However, in 2012, liquid hydrogen accounted for over 90% of small merchant hydrogen utilization in the US. Yet, only a few legacy companies have the knowledge base necessary to handle liquid hydrogen, and the last academic lab in the US … » More …Read Story
How the alumni changed me for the better
Last week I had the pleasure of talking with Jenna Kriebel and AnneMarie Hunter from the WSU Foundation about the impact of alumni donations and philanthropy for the HYPER laboratory (and my career). Throughout my collegiate experience, first as a student athlete and now faculty, I’ve benefited from the generous donations of Land-Grant alumni. Yes, the Land-Grant institutions are public and state supported, but that public support is often literally the general minimum, which sometimes just isn’t enough. Although I’ve written about the many moments that alumni support was perfectly timed to make a difference in keeping us afloat, the conversation with Jenna and … » More …Read Story
Leidenfrost Dusting as a Novel Tool for Dust Mitigation
Lunar dust is an extremely abrasive material that can critically damage and compromise electronics, clothing, and life support systems. In addition, Astronaut Harrison Schmitt and others experienced an ailment they described as “lunar hay fever” from inhalation of lunar dust. Previous removal techniques using brushes, vacuums, and other fluid washes proved ineffective. These methods provided insufficient dust removal and often could damage systems. However, we may have found a solution using the dusting effect of cryogenic liquids.Read Story
Systemic Logistics of a Hydrogen Economy Part 2: The Production Problem
In this multi-part series I’m considering the many logistical challenges of the upcoming hydrogen economy. In Part 1 I considered the people necessary to start and sustain the hydrogen economy. In the subsequent parts/posts I’ll follow the hydrogen through the logistical supply chain to end use. This post is on hydrogen production. Transfer will be Part 3. End use will be Part 4.
Let me be up front that my expertise is hydrogen properties, storage, and distribution (i.e. logistics), and not production. Back in 2005 I saw everyone running into the production and power side (performance minded folks have a tendency towards power) and … » More …Read Story
Systemic Logistics of a Hydrogen Economy Part 1: The People Problem
Welcome 2021 and the World’s new hope for climate salvation: hydrogen.
Since developing the fundamental hydrogen property codes 15 years ago I’ve been waiting for hydrogen to have it’s moment. Despite all of the new press and excitement from folks suddenly interested in hydrogen, I’m here to say that we’re still going to be waiting many more years for hydrogen’s moment to finally arrive. This is evidenced by the many open questions being asked about the future hydrogen economy. We, as a community of stakeholders, still have not addressed many major challenges facing the hydrogen economy. If the ongoing pandemic and struggling vaccine rollout are … » More …Read Story
Hydrogen in Aerospace
When the HYPER lab was founded in 2010, our inaugural project here in the heartland of the aerospace industry, was to build the first liquid hydrogen fueled drone by a university team. Genii, short for the Latin Pondus Hydrogenii (a.k.a. ph, the hydrogen potential) was designed for a 1 kW proton exchange membrane fuel cell and lithium ion batteries.
Our reasons for aerospace as a founding lab focus are clear:
1. Washington State is the #1 aerospace state in the US.Read Story
2. Aerospace is one of the most challenging sectors to decarborize (as described in this 2020 McKinsey report).
3. The weight and power curves of hydrogen fuel technologies shown in the preceding section are close to ideal for typical aircraft.
4. The solid state drive train of hydrogen fuel cell technologies is more reliable, quieter, has lower thermal signature, and higher excess power available for instruments than other technologies.
5. The logistics of hydrogen fuel allow for production on the deck of aircraft carriers or in other remote locations as long as water and electricity are available.
Mounting a Strain Gauge to Composite Surfaces Utilizing High-Performance Epoxy Resins
If I learned anything from my internship with Unitech Composites, it is that surface preparation is essential in all operations of composite layup and assembly. This is true for bonding as well. Surface preparations, although tedious and seemingly unimportant, are key in establishing properties that their subsequent specifications claim. To ensure that an epoxy resin can perform at a specified temperature range for a long time, adherence to the following procedure is required.
This procedure is specifically written for the application of Vishay’s M-bond 43-B, 600, and 610 adhesives in bonding strain gauges to a composite surface. These adhesive systems are a product of Vishay … » More …Read Story
