More than 6,000 participants in 145 cities around the world gathered virtually for last year's Climathon, a global event put on by Impact Hub Houston to unite innovators and collaborate on climate solutions. When Winter Storm Uri left the Texas energy grid in a state of crisis, one Climathon Houston team's proposal for energy reliability became all the more important.

Last year, the City of Houston unveiled its first Climate Action Plan to address the city's challenges and strive to lead the energy transition. It was the perfect roadmap for Climathon Houston, a hackathon where eleven teams gathered to develop and pitch a concept to align with the city's new plan.

Of the three winning teams, one idea was prescient in its approach to energy. Six energy-focused Texans drew up plans for InnoGrid, a cost-effective strategy to build the first microgrid in Houston. What started as a pitch has become a developed proposal gaining collaborator and city interest in the wake of Uri.

Bryan Gottfried, Edward D. Pettitt II, Andi Littlejohn, Paresh Patel, Ben Jawdat, and Gavin Dillingham created InnoGrid to to help achieve the CAP's energy transition and net-zero emissions goals. With climate events increasing rapidly, the team of innovators saw an opportunity to create a sustainable solution — the first Houston microgrid.

In just an hour and a half of brainstorming, the team sought to create a similar model to Austin's Whisper Valley microgrid — a project that's currently in development. While Whisper Valley is a master plan community, the team wanted to create a microgrid to support a larger picture: the city of Houston.

"I had been following transactive energy models [such as] peer-to-peer electricity trading like Brooklyn Microgrid/LO3 Energy and Power Ledger since their inception. This inspired my vision for a novel microgrid that would demonstrate such technologies in the energy capital of the world that is otherwise primarily focused on oil and gas, and natural resources," explains Patel, founder and CEO of e^2: Equitable Energy.

When Pettitt joined the group, he proposed the growing Houston Innovation Corridor as the home to InnoGrid. The four-mile stretch between the Texas Medical Center and Downtown is already home to green technology, making it an ideal fit.

"You're going into an area that was already being redeveloped and had this innovation kind of mentality already," explains Gottfried, a geoscientist and current MBA student at University of Houston Bauer College of Business.

After winning Climathon Houston, the team continued to meet weekly in hopes of making InnoGrid a reality.

The case for a microgrid

The InnoGrid team started with the goal of making energy reliable and resilient in the face of climate change. While previous storms like Hurricane Ike have left millions of Texans without power, Winter Storm Uri was one of the most destructive tragedies to face Texas. The unexpected February storm left 4.5 million Texans without electricity and resulted in at least 111 deaths.

As InnoGrid's team members struggled with burst pipes and loss of power, the team juggled the task of submitting a grant application to the Department of Energy during a catastrophic winter storm. The timing was not lost on them.

"It underscored the need for us to do something like this," shares Gottfried.

To understand how impactful a Houston microgrid can be, you first must understand how a microgrid works. A microgrid is a local energy grid made of a network of generators combined with energy storage. The microgrid has control capability, meaning it can disconnect from a macro grid and run autonomously.

Ultimately, microgrids can provide reliability and drive down carbon emissions. Using smart meters, the grids can even provide real-time energy data to show the inflow and outflow of electricity. In the instance a microgrid does go down, it only affects the community — not the entire state. Likewise, during a power outage to the main grid, a microgrid can break away and run on its own.

Microgrids have been deployed by other cities to mitigate the physical and economic risks caused by power outages, but the use of a project like InnoGrid feels especially timely given recent events and the limitations of the Texas Interconnect.

The Texas grid is isolated by choice, separated from the eastern and western interconnects. Texas' isolated energy grid resulted in a massive failure, proving deregulation can certainly backfire. Updating the electric grid has an expensive price tag, but microgrids show a promising and cost-effective model for the future.

"I thought if microgrids and mini-grids are enabling millions in off-grid frontier markets at the base of the pyramid [like Asia, Sub-Saharan Africa, etc.] to essentially leapfrog legacy energy infrastructure, why should we not upgrade our aging power system with the latest tech that is digitalized, decarbonized, decentralized/distributed, and democratized at the top of the pyramid," asks Patel.

Many hospitals, universities, and large technology firms have already established their own microgrids to protect equipment and provide safety. Still, smaller businesses and homes in the community can suffer during outages.

InnoGrid's proposal seeks to use existing and proven renewable energy sources like wind, solar and geothermal energy. The storage technologies used would include battery, kinetic, compressed air, and geomechanical pumped storage.

"From the perspective of an early-stage hardware startup, one of the most important things is finding a way to validate and test your technology," explains Jawdat, founder and CEO of Revterra and adviser to the InnoGrid team. He explains that the microgrid "can also be a testbed for new technologies, specifically, new energy storage technologies," through potential partnerships with companies like Greentown Labs, which is opening its Houston location soon.

Battling inequity 

While the outlook for a community microgrid is enticing, there are also challenges to address. One key challenge is inequity, which is a key focus of Pettitt who was drawn to the team's goal of providing stability for companies and residences in Houston.

Pettitt, who is seeking a Ph.D. in urban planning and environmental policy at Texas Southern University, has a background in public health and frequently works with the Houston Coalition for Equitable Development without Displacement. "I'm really looking at the intersection of the built environment and how to make cities healthier for its residents," he shares.

"A lot of companies are trying to prevent this climate crisis where we have climate refugees that can't live in certain areas because of ecological damage. But in the process, we don't want to create economic refugees from the gentrification of bringing all of these companies and higher-wage jobs into an area without providing folks the ability to benefit from those jobs and the positive externalities of that development," explains Pettitt.

The InnoGrid would plan to provide positive externalities in the form of energy subsidies and potentially even job training for people who want to work on the grid.

Power to the consumer

Much like the gamification in feel-good fitness trackers and e-learning tools, reward systems can inspire friendly competition and community engagement. InnoGrid's proposal seeks to challenge other major cities to build their own grids and compete with a gamified system.

The Innovation Corridor is currently undergoing major redevelopment, the first 16 acres of which are being developed by Rice Management Company and will be anchored by The Ion, which is opening soon. The timing of this redevelopment would allow a prospective project like InnoGrid to build in visual and interactive aspects that depict energy usage and carbon offsetting.

The microgrid's statistics would also engage Houstonians by sharing up-to-date data through dashboards, apps, and even billboards to track Houston's carbon footprint. Pettitt paints a picture of interactive sidewalk structures, leaderboards, and digital billboards in the public realm to showcase how energy is used day-to-day. The team hopes to build positive feedback cycles that encourage tenants and building owners to be more energy-efficient.

"If we're having an Innovation Corridor, an innovation district, I think the built environment should be innovative too," explains Pettitt.

The future of InnoGrid

Every innovation has to start somewhere. While InnoGrid is in its early stages, the team is working to establish partners and collaborators to make the project a reality.

Inspired by projects like the Brooklyn Microgrid, InnoGrid is in the process of pursuing partnerships with utilities and energy retailers to form a dynamic energy marketplace that pools local distributed energy resources. The team hopes to collaborate with microgrid experts from around the nation like Schneider Electric and SunPower. Other potential collaborators include The Ion, CenterPoint, Greentown Labs, and Rice Management Company.

Can Houston remain the energy capital of the world as it transitions to a net-zero energy future? The InnoGrid team wants to make that happen. The argument for a microgrid in Houston feels even more fitting when you look at the landscape.

"If we are going to create an innovative microgrid that also functions as a testbed for innovators and startups, [we] have proximity to some of the biggest utilities and power generation players right in that sector," explains Patel, who is also an inaugural member of Greentown Labs Houston.

"The microgrid itself is not novel. I think what makes it compelling is to situate that right here in the heart of the energy capital as we, again, reincarnate as the energy transition capital world," Patel continues.

Research, perhaps now more than ever, is crucial to expanding and growing innovation in Houston — and it's happening across the city right under our noses.

In InnovationMap's latest roundup of research news, three Houston institutions are working on life-saving health care research thanks to new technologies.

Rice University scientists' groundbreaking alzheimer's study

According to the Centers for Disease Control and Prevention, Alzheimer’s disease will affect nearly 14 million people in the U.S. by 2060. A group of scientists from Rice University are looking into a peptide associated with the disease, and their study was published in Chemical Science.

Angel Martí — a professor of chemistry, bioengineering, and materials science and nanoengineering and faculty director of the Rice Emerging Scholars Program — and his team have developed a new approach using time-resolved spectroscopy and computational chemistry, according to a news release from Rice. The scientists "found experimental evidence of an alternative binding site on amyloid-beta aggregates, opening the door to the development of new therapies for Alzheimer’s and other diseases associated with amyloid deposits."

Amyloid plaque deposits in the brain are a main feature of Alzheimer’s, per Rice.

“Amyloid-beta is a peptide that aggregates in the brains of people that suffer from Alzheimer’s disease, forming these supramolecular nanoscale fibers, or fibrils” says Martí in the release. “Once they grow sufficiently, these fibrils precipitate and form what we call amyloid plaques.

“Understanding how molecules in general bind to amyloid-beta is particularly important not only for developing drugs that will bind with better affinity to its aggregates, but also for figuring out who the other players are that contribute to cerebral tissue toxicity,” he adds.

The National Science Foundation and the family of the late Professor Donald DuPré, a Houston-born Rice alumnus and former professor of chemistry at the University of Louisville, supported the research, which is explained more thoroughly on Rice's website.

University of Houston professor granted $1.6M for gene therapy treatment for rare eye disease

A University of Houston researcher is working on a way to restore sight to those suffering from a rare genetic eye disease.

Muna Naash, the John S. Dunn Endowed Professor of biomedical engineering at UH, is expanding a method of gene therapy to potentially treat vision loss in patients with Usher Syndrome Type 2A, or USH2A, a rare genetic disease.

Naash has received a $1.6 million grant from the National Eye Institute to support her work. Mutations of the USH2A gene can include hearing loss from birth and progressive loss of vision, according to a news release from UH. Naash's work is looking at applying gene therapy — the introduction of a normal gene into cells to correct genetic disorders — to treat this genetic disease. There is not currently another treatment for USH2A.

“Our goal is to advance our current intravitreal gene therapy platform consisting of DNA nanoparticles/hyaluronic acid nanospheres to deliver large genes in order to develop safe and effective therapies for visual loss in Usher Syndrome Type 2A,” says Naash. “Developing an effective treatment for USH2A has been challenging due to its large coding sequence (15.8 kb) that has precluded its delivery using standard approaches and the presence of multiple isoforms with functions that are not fully understood."

Stress can impact the human body in a number of ways — from high blood pressure to hair loss — but one Houston scientist is looking into what happens to bodies in the long term, from age-related neurodegeneration to cancer.

Dr. Steven Boeynaems is assistant professor of molecular and human genetics at Baylor College of Medicine. His lab is located at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, and he also is a part of the Therapeutic Innovation Center, the Center for Alzheimer’s and Neurodegenerative Diseases, and the Dan L Duncan Comprehensive Cancer Center at Baylor.

Recently, the Cancer Prevention and Research Institute of Texas, or CPRIT, awarded Boeynaems a grant to continue his work studying how cells and organisms respond to stress.

“Any cell, in nature or in our bodies, during its existence, will have to deal with some conditions that deviate from its ideal environment,” Boeynaems says in a BCM press release. “The key issue that all cells face in such conditions is that they can no longer properly fold their proteins, and that leads to the abnormal clumping of proteins into aggregates. We have seen such aggregates occur in many species and under a variety of stress-related conditions, whether it is in a plant dealing with drought or in a human patient with aging-related Alzheimer’s disease."

Now, thanks to the CPRIT funding, he says his lab will now also venture into studying the role of cellular stress in brain cancer.

“A tumor is a very stressful environment for cells, and cancer cells need to continuously adapt to this stress to survive and/or metastasize,” he says in the release.

“Moreover, the same principles of toxic protein aggregation and protection through protein droplets seem to be at play here as well,” he continues. “We have studied protein droplets not only in humans but also in stress-tolerant organisms such as plants and bacteria for years now. We propose to build and leverage on that knowledge to come up with innovative new treatments for cancer patients.”
