In Houston, air pollution is usually more of an abstract concept than a harsh reality. But in parts of Chile, the consequences of heating homes with wet wood are catching up to residents.

“Given all the contamination, there are times kids aren’t allowed to go to school. The air pollution is really affecting people’s health,” says Agustín Ríos, COO of Lignium Energy.

Additionally, the methane and nitrous oxide produced by cattle farming are a problem. But Lignium Energy, an international company started in Chile and now headquartered in Houston’s Greentown Labs, has a solution that can solve both problems by upending the latter.

“There’s a lack of solutions with the problem of manure. Methane gases are destroying our planet,” says CEO and co-founder Enrique Guzmán. He goes on to say that most solutions currently being developed are expensive and complex. But not Lignium Energy’s method, invented by co-founder José Antonio Caraball.

Caraball has patented an extraordinarily simple concept. Lignium separates the solid from liquid excretions, then cleans the solid to generate a hay-like biomass. Biomass refers to organic matter that can be used as fuel. What Lignium makes from the cattle evacuations is a clean, odorless and highly calorific biomass.

Essentially, Lignium combats greenhouse gasses with a green fuel that boasts an enviably low carbon footprint. “Our process is very cheap and very simple. That’s why we are a great solution,” explains Guzmán.

Caraball, an industrial engineer, came up with the idea six years ago, says Guzmán. Five years ago, he began working with the company, one year ago, Guzmán and Ríos picked up and moved to Houston.

“We decided to move out of Chile due to market size,” says Ríos. However, the product is already being sold to consumers in its homeland.

Why Houston? The reason was twofold. As an energy company, Ríos says that they wanted to be in “the energy capital of the world.” But Texas is also one of the largest sites of cattle farming on the planet. Lignium prefers to work with farms with more than 500 head to optimize harvesting the waste that becomes biomass.

With that in mind, Lignium has partnered with Southwest Regional Dairy Center in Stephenville, Texas, a little more than an hour southwest of Fort Worth, a town known as the world’s rodeo capital. The facility is associated with Texas A&M, though Guzmán says Lignium is not officially associated with the university.

Guzmán says that the company is currently hiring a team member to help Lignium figure out commercial logistics, as well as four or five other Houstonians who will help them take their product to market in the United States, and eventually around the globe. For now, he predicts that they will be able to sell to consumers in this country by early next year, if not the fourth quarter of 2023.

“We are very committed to the solution because, at the end of the day, if we do good work with the company, we are sure we can give better conditions to the cattle industry,” says Guzmán. “Then we can make a big impact on a real problem.

Houston energy tech company launches B2B carbon footprint calculator

seeing green

Houston-area energy tech startup Syzygy Plasmonics is helping businesses and other organizations get a handle on greenhouse gas emissions.

Syzygy just released a free online tool at CarbonModel.com that enables users to calculate the greenhouse gas emissions and emission-reduction costs in as little as 60 seconds. It’s a more straightforward way of making those calculations than is offered by Argonne National Laboratory’s Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) model, the startup says.

Syzygy says it created the tool in light of heightened interest surrounding clean hydrogen. The recently passed federal Inflation Reduction Act includes tax credits for clean hydrogen projects.

“New and existing hydrogen producers, consumers, and project developers are actively seeking to identify and quantify the impacts that the tax credits will have on project economics and feasibility,” Syzygy says in a news release.

Syzygy co-founder and CEO Trevor Best calls the Inflation Reduction Act “a major tailwind” for energy transition and hydrogen adoption.

“Existing hydrogen producers now have the fiscal support needed to sanction new projects. And companies that had been mulling hydrogen as a new business are incentivized to move more quickly,” Best says. “Both existing and new entrants in the hydrogen market want to know if their hydrogen is clean enough to qualify for [Inflation Reduction Act] tax credits.”

Murtuza Marfani, vice president of finance and corporate development at Syzygy, says tools like GREET are “demanding and complex” when it comes to figuring out tax credits for clean hydrogen projects.

“CarbonModel.com simplifies early-stage analysis,” Marfani says. “We see it contributing to the momentum from the [Inflation Reduction Act] by enabling organizations to quickly assess project viability. It will also help them address any gaps in knowledge before committing to full-project modeling.”

CarbonModel.com currently focuses on hydrogen production, but Syzygy says future versions will provide cost and carbon footprint assessments for ammonia, e-fuels, and other chemicals.

Syzygy has developed reactor technology that uses light from ultra-high-efficiency LEDs to power chemical reactions, eliminating the traditional method of producing hydrogen with heat from burning fuel.

In May, Syzygy said it was relocating its headquarters from 9000 Kirby Dr. in Houston to Pearland. It’s leasing a 44,800-square-foot building in Pearland for its headquarters, R&D operations, and manufacturing facilities. The new facility is at 3250 S. Sam Houston Pkwy.

Founded in 2017, Syzygy has created technology that generates clean hydrogen from various feedstocks. Syzygy’s technology is based on an area of science known as photocatalysis, which uses light from LEDs driven by renewable electricity to conduct chemical reactions. The technology can electrify the production of chemicals such as hydrogen, liquid fuels, and fertilizer.

In 2021, the company — whose technology is based on Rice University research — raised $23 million in series B funding. Syzygy has collected a total of $30 million, according to Crunchbase.

Houston steps to top of list of U.S. cities with lowest carbon footprints

seeing green

People looking to travel to a sustainable city probably don’t have Texas spots at the top of their lists. Images of oil, cars, and blasting air conditioners spring up. The Texas power grid, no one need remind us, is barely hanging on.

But Texas blew other states away for lowest carbon footprint per capita, landing Houston at the top of the list compiled by travel blog Park Sleep Fly. Austin followed (No. 3), then San Antonio (No. 4) and Dallas (No. 9). Only Florida appeared twice in the top 10, and none matched Texas with four cities.

Among the 50 most visited in the U.S., those with the lowest carbon footprint are:

1. Houston
2. Los Angeles
3. Austin
4. San Antonio
5. Tampa, Florida
6. Salt Lake City
7. Phoenix
8. Miami
9. Dallas
10. Portland, Oregon

Houston is not exactly a green place, with less-than-ideal utilization of public transportation. It and Dallas tied for third place among least sustainable cities in the same report.

“Public transit isn’t the most popular mode of transportation in Houston, but it does exist,” an online publication called TripSavvy drably admits. The city takes credit for employing “nearly one third” of the nation’s oil and gas extraction workers.

On the renewable side, however, Houston claims more than 100 solar energy companies, and at least half of its corporate research and development centers pursue “energy technology and innovation.” And its huge population spreads the load, leaving only 14.6 metric tons of carbon dioxide per resident — the same as Los Angeles. Big cities seem to have an advantage in this rating system.

Austin is just behind Houston at 15 metric tons per capita, neck-and-neck with San Antonio at 15.2. These two cities have smaller populations to distribute their total footprint, but are generally seen as eco-friendly. Austin got a big head start in 1991 with the introduction of the Austin Energy Green Building program — the first of its kind in the whole country — which created an evaluation system for individual building sustainability that’s still in use. Dallas' carbon footprint is the largest of the Texas cities in the ranking, at 16.5 metric tons per capita.

As such a multifaceted issue (especially tied up in economic concerns), sustainability is hard to pin down from city to city. The multiplicity of this list is yet another indicator that Texas as a whole is a much more nuanced place than many people think.

Houston expert shares tips for shrinking your lab's carbon footprint

houston voices

Trying to make your lab greener? Here are some practical examples of how to reduce your lab's carbon footprint and increase sustainability. Since China stopped accepting certain types of plastic waste from the United States and Europe in 2017, the need to dispose of hundreds of single-use plastic vials and other materials (per researcher, each year!) has created an avalanche of waste.

The "single use" problem

COVID-19 has led to even more single-use plastics in labs – and in our everyday lives. The sheer number of gloves, testing kits and even masks we throw away is incredible. "The majority of masks are manufactured from long-lasting plastic materials, and if discarded can persist in the environment for decades to hundreds of years," wrote authors from the University of Portsmouth at the Conversation.com.

Reduce, reuse, recycle

Labs are full of other single-use plastics such as pipette tips, weighing boats, tubes, flasks, reagent bottles, cuvettes, and more. 'Reduce, reuse and recycle' is a fine mantra, but how do researchers cut down on plastics when the sterility of equipment is a concern?

According to the UK's Chemical and Engineering News magazine, "Different users have optimized washing protocols to get pipette tips clean enough for different lab techniques, including mass spectrometry or toxicology and immunology assays.

Earlier this year, for example, researchers at the National Institutes of Health's National Center for Advancing Translational Sciences found their washed pipettes gave the same results as new tips for preparing small-interfering-RNA screening libraries." Customers of Grenova, a lab equipment firm, have reported that some tips can reused 25-40 times.

Baby it's cold

In Nature, Jyoti Madhusoodanan wrote: "Scientists are increasingly aware of the disproportionate environmental footprint of their research. Academic research facilities consume three to six times as much energy as commercial buildings, much of that due to refrigeration and ventilation systems." The has led some third-party "green companies" employed by labs to hold entire conferences around ultra-low temperature freezers. In a feature advertisement in Nature Portfolio, a statistic read: "An average Ultra-Low Temperature freezer consumes as much energy as a single-family home (~20 kWh/day)."

Help for scientists

There are non-profits that will help you mitigate the amount of waste produced by your lab. One of these, My Green Lab, said on its website: "Run 'for scientists, by scientists,' we leverage our credibility and track record to develop standards, oversee their implementation, and inspire the many behavioral changes that are needed throughout the scientific community."

And it offers a free training course for "ambassadors" – those who would like to guide their lab toward sustainable practices.

Report: Houston's VC trends so far in 2024 and what to watch for the rest of the year

by the numbers

Houston-based geothermal company Fervo Energy accounted for more than half of the venture capital raised by Houston-area startups in the first quarter of 2024.

The region’s VC haul in the first quarter totaled $462.4 million, according to the PitchBook-NCVA Venture Monitor. That’s up from $290.4 million during the same period in 2023 and from $285.8 million in the fourth quarter of last year. Click here to see the Q1 rounds as reported by InnovationMap.

Fervo’s latest funding round, announced in February, represented $244 million (52 percent) of the region’s VC total for the first quarter of 2024.

A report released in March by PitchBook indicated that VC funding last year for geothermal power reached $431 million across 21 deals. As of late February 25 — four days ahead of the Fervo announcement — $165.5 million in VC funding had been pumped into the geothermal sector this year, according to PitchBook.

“The recent VC deal activity with the geothermal power sector underscores a vibrant and evolving market, but still one that garners far less VC than other renewables,” says the report.

In all, Houston-area startups made 38 VC deals in this year’s first quarter, the PitchBook-NVCA Venture Monitor says. That’s down from 42 in the fourth quarter of 2023 and 43 in the first quarter of 2023. Nationwide, the deal count fell sharply in the first quarter of 2024 vs. the first and fourth quarters of last year.

The PitchBook-NVCA Venture Monitor report shows that nationwide, the $36.6 billion in VC investments recorded during the first quarter of 2024 “remained relatively on pace with the past year.”

“However, it would be a mistake to hyperfocus on the results of a single quarter whose results were a bit farther left on the bell curve than usual. The venture capital … business cycle effectively reset in recent years, and as of early 2024, it still appears to be searching for its level,” says the report.

“It is too early to tell where 2024 is going, but the game is on, and America’s VCs are ready for it,” the report adds. “In 2022, our world changed; in 2023, we accepted it was not changing back; and in 2024, we are building what is next.”

In a bit of good news for the Houston area, the report cites cleantech/energy as one of two sectors that venture capitalists should not overlook. The other sector: cybersecurity.

But in a bit of not-so-good news for the region, the report notes a slowdown in VC deals in the healthcare sector over the past two years in the wake of “pandemic-fueled capital exuberance.”

“Yet the healthcare sector differentiates itself from the rest of the market by demonstrating many unmet needs that could have a profound impact on society, particularly around disease diagnosis and treatment,” the report goes on to say. “On top of the immense opportunity set for disruption within healthcare, investor enthusiasm around AI adoption in drug development further speaks to the demand for better solutions in biotech through groundbreaking innovations.”

Houston dazzles as most diverse large city in U.S., report says

we're No. 1

Living in a multicultural city comes with many benefits. Diverse communities bring new perspectives, greater versatility, and economic boosts, to name a few. And according to a new study by WalletHub, Houston is among the most diverse places in the nation.

Houston is getting some time in the spotlight in WalletHub's annual ranking of the "Most Diverse Cities in the U.S. (2024)," maintaining its position as the No. 1 most diverse large city in America, and the No. 4 overall most diverse. The report compared 501 U.S. cities across 13 metrics in five categories that encompass "diversity" across socioeconomic, cultural, economic, household, and religious factors.

Space City earned 72.37 out of a total 100 possible points, following behind Gaithersburg, Maryland (No. 1), Silver Spring, Maryland (No. 2), and Germantown, Maryland (No. 3). Arlington, Texas rounded out the top five. Houston is still holding strong as the most diverse large U.S. city after first taking the crown in WalletHub's 2021 report.

The city performed the best in two overall major categories for socioeconomic and cultural diversity, earning a respective rank of No. 27 and No. 31 out of all 501 cities in the study. Houston's religious diversity earned it No. 54, while it fell behind when it came to household and economic diversity, earning No. 112 and No. 156.

More specifically, Houston performed the best in the rankings for its linguistic diversity (No. 25), industry diversity (No. 28), and educational-attainment diversity (No. 29). But the city fell the farthest behind in the rankings for age diversity (No. 310) and worker-class diversity (No. 340).

Here's how Houston performed within the study's remaining categories out of all 501 cities:

  • 45th – Racial and ethnic diversity
  • 119th – Household-type diversity
  • 179th – Household-size diversity
  • 206th – Occupational diversity
  • 226th – Income diversity
  • 246th – Marital-status diversity
  • 249th – Birthplace diversity

"The most diverse cities demonstrate diversity in many dimensions – not just in race and gender but also everything from residents’ languages and birthplaces to their job types and household sizes," said WalletHub analyst Cassandra Happe in the report. "These cities blend together a multitude of different perspectives, helping people to better understand the world around them and become more empathetic. This exchange of ideas also tends to increase the economic success of diverse cities."

Besides Houston and Arlington, the only other Texas city to earn a place among the top 10 most diverse cities in the U.S. was Dallas, which ranked No. 8.

Other Texas cities that earned spots in the report include Fort Worth (No. 22), Austin (No. 70), Plano (No. 83), San Antonio (No. 87), Corpus Christi (No. 125), El Paso (No. 253), and Laredo (No. 468).
