Houston startup rings NYSE closing bell

A Houston company got to take the national stage by ringing the closing bell at the New York Stock Exchange, and for Katie Mehnert, founder of ALLY Energy, it was a chance to reflect on the progress the industry as a whole has progressed.

"As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero," Mehnert writes in her guest column. Read the full piece here.

Deadline not to miss: ACCEL

Advancing Climatetech and Clean Energy Leaders Program, or ACCEL, has opened applications for it's second cohort. The program — from Greentown Labs and Browning the Green Space — provides access to funding, networking connections, incubation space, mentorship, resources, and opportunities for energy tech founders of color for a year.

“ACCEL is one of the most impactful, meaningful programs we’ve run to date,” Greentown Labs CEO and President Kevin Knobloch says in a news release. “We are eager to expand upon the great success and momentum of year one, and to welcome another incredible cohort of BIPOC-led startups that are developing much-needed climatetech solutions. We’re equally committed to helping these companies accelerate and deploy their solutions, while also helping to build a more diverse, inclusive climatetech workforce—ACCEL sits at the nexus of those two critical efforts.” Read more about the program.

Founder on ringing the NYSE bell and shining a spotlight on the future of energy in Houston

guest column

As I stood on the platform at the world’s largest stock exchange to ring the closing bell, surrounded by 130 people from across the energy industry, I saw it clearly: how the private sector will play a major role in getting us to an era of net zero. The people who power the energy industry will do the hard work. We’ve already begun. And we’re unafraid of the long journey ahead — something more than 40 of us exemplified that weekend by running a marathon.

The trip to New York City days ago was an exhilarating whirlwind. But it was also something much more: A chance to show the markets, the nation, and the world that Houston is leading the energy transition. (It didn’t hurt that we popped up on Good Morning America.)

From the beginning, the idea behind this pair of events — ringing the bell at the New York Stock Exchange and running the TCS New York City Marathon — was aimed at sending crucial messages. That recognizing climate change and building solutions is an obligation and an opportunity. That the energy industry understands this. That investors have good reason to support climate tech, one of the most exciting and fastest growing sectors. And, last but not least, that people’s perceptions of Houston as being all about oil and gas are simply wrong.

The dozens of us who gathered came from across the country and around the world, But by far, the largest contingent was from right here in Houston. Executives, engineers, entrepreneurs, and other innovators took part. People spearheading projects in every facet of energy, from wind to solar, carbon capture, and other methods of dramatically reducing carbon emissions. All as one team.

Those who traveled from “the energy capital” knew how important it was to highlight our Houston pride. As a new report from the Texas Climate Tech Collective points out, the biggest problem in the city’s climate tech ecosystem is its image. “Outsider perceptions of Houston often draw on negative stereotypes,” the report explains. “The number one disadvantage survey respondents chose – even more than access to VC capital – was Houston’s anti-climate reputation outside the state.”

It’s a problem I’ve been trying to combat for years, including through op-eds in national and international media outlets. Fortunately, the idea is starting to get through. Just days ago, the Financial Times reported that Houston claimed the top spot in this year’s FT-Nikkei Investing in America rankings by “moving beyond oil.” Our city, the paper said, “has become a hub for green energy innovation by building on its hydrocarbon past.”

Houston, and Texas a whole, should be immensely proud of this. But the energy industry has a long history of failing to tell its own stories. It’s time to change that. In fact, the recommendations in the collective’s report include “campaigning to improve Houston’s reputation, improving promotion of Houston’s energy transition initiatives and accomplishments, educating politicians and consumers, reversing anti-climate perception.”

Building bridges

All of the challenges we face, including the perception problem, will only be overcome if we work together. So the era of siloes must end. Climate change is an “all hands on deck” situation. This means companies large and small, as well as businesses focusing on all forms of energy, need to develop a “one-team” mentality.

We also need to step up our engagement with public sector entities. A great deal of public sector investment is being poured into renewable energy programs. Since I’ve served as an ambassador to the Department of Energy’s Equity in Energy initiative and a member of the National Petroleum Council, I’ve met many people in government who are eager to cooperate with us to help ensure that the United States leads the way in the energy transition.

The need for building these kinds of bridges is another reason that many of the participants in our Women & Allies in Energy team saw the New York City marathon as such a strong metaphor. It’s known for its bridges. And having run across all of them — and stopped for a quick selfie on the toughest one of all, the Queensboro Bridge — I’m reminded of their importance. I was happy to see that another recommendation in the collective’s report speaks directly to this. It calls for, “Building bridges between public and private, energy corporates and startups, universities and startups, and startups and mentors; seeking partnerships with other ecosystems; improving resources for early stage startups.”

We also need to build bridges among groups of people. More than ever, the industry needs diversity, equity and inclusion. (See my recent piece for Fast Company about why the C-Suite should double down, not shy away from, DEI.) We need to welcome people with all sorts of backgrounds, experiences, and perspectives. The greatest form of capital the energy sector has in building the future is not financial. It’s human capital. And the greatest natural resource we have is not one form of energy. It’s the people whose hard work, creativity, collaboration, and grit will get us to the finish line.

To help make all this happen, I’m calling for Houston to come together on climate change. Capitalizing on the annual Climate Week in New York City, and building on an event the City of Houston organized in 2021, let’s bring all industries and all people together next fall to show that we recognize climate reality, and are ready to take action together.

The next generation

While I did have the chance to lead the delegation at the NYSE closing bell, I did not hold the gavel — at least, not by myself. Instead, I handed it to my 12-year-old daughter, Ally. (Yes, her name is a big part of the inspiration behind our company name, ALLY Energy.)

As leaders in energy, we have to keep our eyes firmly focused on the next generation. This means not only giving them a strong supply of energy and healthier conditions on the planet. It also means giving them future job opportunities.

It’s up to us to build the pipeline for future talent. We need to improve STEAM (science, technology, engineering, arts and math) education. And we need to demonstrate to people who are currently underrepresented in our industry — such as women and members of minority groups — that they have a future in the world’s most exciting industry.

We can do this. We can get out of our bubble, show our Houston pride to the world, and lead the way to “energy 2.0” — an era of plentiful energy supplies and net-zero emissions. After all, dozens of us have returned from New York City with a mission: capitalize on all that momentum, join together as a team, and run the race to net zero.

Houston researchers develop energy-efficient film for AI chips

AI research

A team of researchers at the University of Houston has developed an innovative thin-film material that they believe will make AI devices faster and more energy efficient.

AI data centers consume massive amounts of electricity and use large cooling systems to operate, adding a strain on overall energy consumption.

“AI has made our energy needs explode,” Alamgir Karim, Dow Chair and Welch Foundation Professor at the William A. Brookshire Department of Chemical and Biomolecular Engineering at UH, explained in a news release. “Many AI data centers employ vast cooling systems that consume large amounts of electricity to keep the thousands of servers with integrated circuit chips running optimally at low temperatures to maintain high data processing speed, have shorter response time and extend chip lifetime.”

In a report recently published in ACS Nano, Karim and a team of researchers introduced a specialized two-dimensional thin film dielectric, or electric insulator. The film, which does not store electricity, could be used to replace traditional, heat-generating components in integrated circuit chips, which are essential hardware powering AI.

The thinner film material aims to reduce the significant energy cost and heat produced by the high-performance computing necessary for AI.

Karim and his former doctoral student, Maninderjeet Singh, used Nobel prize-winning organic framework materials to develop the film. Singh, now a postdoctoral researcher at Columbia University, developed the materials during his doctoral training at UH, along with Devin Shaffer, a UH professor of civil engineering, and doctoral student Erin Schroeder.

Their study shows that dielectrics with high permittivity (high-k) store more electrical energy and dissipate more energy as heat than those with low-k materials. Karim focused on low-k materials made from light elements, like carbon, that would allow chips to run cooler and faster.

The team then created new materials with carbon and other light elements, forming covalently bonded sheetlike films with highly porous crystalline structures using a process known as synthetic interfacial polymerization. Then they studied their electronic properties and applications in devices.

According to the report, the film was suitable for high-voltage, high-power devices while maintaining thermal stability at elevated operating temperatures.

“These next-generation materials are expected to boost the performance of AI and conventional electronics devices significantly,” Singh added in the release.
