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.

Texas university's innovative 'WaterHub' will dramatically reduce usage by 40%

Sustainable Move

A major advancement in sustainability is coming to one Texas university. A new UT WaterHub at the University of Texas at Austin will be the largest facility of its kind in the U.S. and will transform how the university manages its water resources.

It's designed to work with natural processes instead of against them for water savings of an estimated 40 percent. It's slated for completion in late 2027.

The university has had an active water recovery program since the 1980s. Still, water is becoming an increasing concern in Austin. According to Texas Living Waters, a coalition of conservation groups, Texas loses enough water annually to fill Lady Bird Lake roughly 89 times over.

As Austin continues to expand and face water shortages, the region's water supply faces increased pressure. The UT WaterHub plans to address this challenge by recycling water for campus energy operations, helping preserve water resources for both the university and local communities.

The 9,600-square-foot water treatment facility will use an innovative filtration approach. To reduce reliance on expensive machinery and chemicals, the system uses plants to naturally filter water and gravity to pull it in the direction it needs to go. Used water will be gathered from a new collection point near the Darrell K Royal Texas Memorial Stadium and transported to the WaterHub, located in the heart of the engineering district. The facility's design includes a greenhouse viewable to the public, serving as an interactive learning space.

Beyond water conservation, the facility is designed to protect the university against extreme weather events like winter storms. This new initiative will create a reliable backup water supply while decreasing university water usage, and will even reduce wastewater sent to the city by up to 70 percent.

H2O Innovation, UT’s collaborator in this project, specializes in water solutions, helping organizations manage their water efficiently.

"By combining cutting-edge technology with our innovative financing approach, we’re making it easier for organizations to adopt sustainable water practices that benefit both their bottom line and the environment, paving a step forward in water positivity,” said H2O Innovation president and CEO Frédéric Dugré in a press release.

The university expects significant cost savings with this project, since it won't have to spend as much on buying water from the city or paying fees to dispose of used water. Over the next several years, this could add up to millions of dollars.

Texas female-founded companies raised more than $1 billion in 2024, VC data shows

by the numbers

Female-founded companies in Dallas-Fort Worth may rack up more funding deals and more money than those in Houston. However, Bayou City beats DFW in one key category — but just barely.

Data from PitchBook shows that in the past 16 years, female-founded companies in DFW collected $2.7 billion across 488 deals. By comparison, female-founded companies in the Houston area picked up $1.9 billion in VC through 343 deals.

Yet if you do a little math, you find that Houston ekes out an edge over DFW in per-deal values. During the period covered by the PitchBook data, the value of each of the DFW deals averaged $5.53 million. But at $5,54 million, Houston was just $6,572 ahead of DFW for average deal value.

Not surprisingly, the Austin area clobbered Houston and DFW.

During the period covered by the PitchBook data, female-founded companies in the Austin area hauled in $7.5 billion across 1,114 deals. The average value of an Austin deal: more than $6.7 million.

Historically, funding for female-established companies has lagged behind funding for male-established companies. In 2024, female-founded companies accounted for about one-fourth of all VC deals in the U.S., according to PitchBook.

PitchBook noted that in 2024, female-founded companies raised $38.8 billion, up 27 percent from the previous year, but deal count dropped 13.1 percent, meaning more VC for fewer startups. In Texas, female-founded companies brought in $1.3 billion last year via 151 deals. The total raised is the same as 2023, when Texas female founders got $1.3 billion in capital across 190 deals.

“The VC industry is still trying to find solid footing after its peak in 2021. While some progress was made for female founders in 2024, particularly in exit activity, female founders and investors still face an uphill climb,” says Annemarie Donegan, senior research analyst at PitchBook.
