The Ion in Midtown has some new tenants taking up residence in its 90 percent-leased building.

Occidental Petroleum Corporation, Fathom Fund, and Activate are the latest additions to the Ion, according to a news release from Rice University and the Rice Real Estate Company, which own and operate the 16-acre Ion District where the Ion is located. With the additions, the building has just 10 percent left up for grabs.

“As the Ion continues to attract leading companies and organizations across industries, it’s clear that our vision of creating a dynamic and collaborative environment for innovation is resonating,” Ken Jett, president of the Rice Real Estate Company and vice president of facilities and capital planning at Rice, says in the release. “We are proud to set the standard for how the workplace can evolve to foster the commercialization and growth of transformative technologies that enhance quality of life in our community and beyond.”

Oxy, which was named a corporate partner of the Ion last year, now has nearly 6,500 square feet on the fourth floor. The build out process is slated to be completed by early 2025.

While Oxy represents the corporate side of innovation, the other two additions have their own roles in the innovation arena. Houston-based Fathom Fund, which launched its $100 million fund earlier this year, is targeting deep-tech venture opportunities and is led by Managing Partners Paul Sheng and Eric Bielke.

Founded in Berkeley, California, Activate, which announced its expansion into Houston in 2023, has officially named its local office in the Ion. The hardtech-focused incubator program recently named its inaugural cohort and opened applications for the 2025 program.

Other recent joiners to the Ion includes Kongsberg Digital, Artemis Energy Partners, CES Renewables, and Eleox.

“The partnerships we’ve forged are vital to shaping the Ion into a vibrant ecosystem for startups, where collaborative innovation is not only driving local economic growth but also positioning Houston as a global leader in the energy transition,” Paul Cherukuri, chief innovation officer at Rice University, says. “With our team leading the programming and activation across the Ion district, we are creating companies that harness cutting-edge technology for the benefit of society—advancing solutions that contribute to social good while addressing the most pressing challenges of our time. This powerful network is redefining Houston’s role in the future of energy, technology, and social impact.”

Houston-based Catalyze, a developer of independent power systems, has teamed up with commercial real estate services powerhouse Cushman & Wakefield to expand installation of solar panels and battery storage technology at U.S. commercial and industrial properties.

The two companies say the partnership will help owners and tenants of office buildings, warehouses, and other commercial properties reduce utility costs, boost operating income, achieve environmental goals and ease stress on the power grid.

“This partnership marks a significant step forward in our mission to accelerate the adoption of renewable energy among commercial and industrial customers, benefiting both tenants and building owners,” Jared Haines, CEO of Catalyze, says in a news release.

The partnership will enable Cushman & Wakefield to decrease greenhouse gas emissions at facilities it manages for clients as well as its own corporate offices. The real estate sector accounts for about 40 percent of greenhouse gas emissions around the world.

“Our strategic partnership with Catalyze is a testament to our shared commitment to decarbonize the built environment by being at the forefront of the clean energy revolution,” says Jessica Francisco, Cushman & Wakefield’s chief sustainability officer. “Together, we are poised to advance the adoption of solar and storage technologies while driving down costs for our clients.”

In May, Catalyze announced that it secured $100 million in financing from NY Green Bank to support a 79 megawatt portfolio of community distributed generation solar projects across the state of New York.

Dow digs up new office space in Houston's Energy Corridor

moving in

Dow Chemical has signed up to be the anchor tenant at the CityCentre Six office tower under construction in Houston’s Memorial City area.

Dow will occupy nearly two-thirds (65 percent) of the 308,000 square feet of office space at the 19-story building, or about 200,000 square feet. The company will relocate employees there from its Houston Dow Center offices at Enclave Plaza in the Energy Corridor.

The current lease expires in 2026. Dow has leased the Energy Corridor space for 15 years.

Houston-based real estate investor and developer Midway recently broke ground on the $87.5 million, 320,000-square-foot CityCentre Six tower, which will be adjacent to the headquarters of Marathon Oil.

“Dow’s commitment as the anchor tenant has been a driving force behind the project’s strong momentum and underscores the strong leasing demand for CityCentre office space, which remains 100 percent leased,” says Chris Seckinger, vice president of investment and development at Midway. “Their presence not only confirms the tower’s status as a premier business destination but also reflects the confidence leading enterprises have in our vision for the district.”

The new tower, set to be completed in 2026, is one of the latest additions to the 47-acre CityCentre mixed-use development.

“Our plans for CityCentre’s north site have been in the works for almost a decade, and CityCentre Six is a significant step towards realizing our long-term vision for the development,” Seckinger said in a January 2024 news release.

Midway’s CityCentre Seven, a six-story office building and hotel, is also under construction at the mixed-use development. The Four Points by Sheraton Houston West hotel currently occupies the site.

Global real estate manager to tap into solar energy to power Houston portfolio

shine on

Commercial real estate manager Brookfield Properties, a major office landlord in Houston, is plugging into solar energy to power its local portfolio.

The New York City-based company plans to rely on a new-build solar power plant to supply all of the electricity for its 10.3 million-square-foot, 10-building office portfolio in the Houston area. Brookfield’s key properties here include:

  • The 3.1 million-square-foot Allen Center complex
  • The more than 1.1 million-square-foot Heritage Plaza
  • The 1.1 million-square-foot 1600 Smith Street tower
  • The nearly 850,000-square foot TotalEnergies Tower

Laura Montross, vice president of communications for Brookfield Properties, tells Realty News Report that the solar power plant will be operating by 2026.

Each year, the company’s Houston portfolio uses about 90,000 megawatt-hours of electricity, “which is unlikely to take up the total capacity of a new solar power plant,” she says, “so the excess capacity will be available to other buyers or the utility grid operator for purchase.”

Montross says Brookfield is in talks with several developers of solar power plants about the Houston project, but neither a site nor a contractor has been chosen yet.

Brookfield announced June 28 that its entire U.S. office portfolio will run on zero-emissions electricity by 2026. The switch is expected to reduce carbon emissions within the more than 70-million-square-foot portfolio by about 80 percent.

“Instead of taking incremental steps or waiting for others to act, we are completely transforming how we power office buildings throughout the United States,” Ben Brown, managing partner of Brookfield Real Estate, says in a news release.

Brookfield Properties says electricity for the nationwide office portfolio will come from four sources: hydropower (49 percent), solar and wind power (33 percent), and nuclear power (18 percent). Outside Houston, the company maintains a large office presence in the New York City, Los Angeles, Denver, and Washington, D.C. markets.

“Not only will [this strategy] significantly advance our goal of transitioning our entire portfolio to net zero carbon,” Brown says, “but also we are confident that both the increased demand for zero-emissions electricity it will create and the industry precedence it will set will be a game-changer for how state-of-the-art office buildings are powered throughout the country.”

Texas ranks low on most energy-efficient states report

by the numbers

Texas has room to improve when it comes to energy efficiency, recent data from WalletHub shows.

The personal finance website ranked Texas at No. 35 on the latest Most & Least Energy-Efficient States list. Texas improved by one spot on the 2025 report, after coming in at No. 36 last year.

The report measured and ranked the efficiency of auto energy and home energy consumption in the 48 U.S. mainland states based on data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration and the U.S. Department of Transportation – Federal Highway Administration.

Texas earned an overall score of 50.60. It was ranked No. 27 for home energy efficiency and No. 41 for auto efficiency. By comparison, No. 1-ranked Vermont earned a score of 85.30, ranking No. 2 for home energy and No. 6 for out energy.

The top five overall states included:

  • No. 1 Vermont
  • No. 2 California
  • No. 3 Washington
  • No. 4 New York
  • No. 5 Massachusetts

South Dakota earned the top rank for home energy efficiency, and Massachusetts earned the top rank for energy efficiency.

“Energy efficiency doesn’t just help save the planet – it also helps save you money by lowering the amount of electricity, gas, oil or other types of energy you need to consume. While there are some steps you can take to become more energy-efficient on your own, living in the right area can give you a big boost," WalletHub analyst Chip Lupo said in the report. "For example, certain states have much better public transportation systems that minimize your need to drive, at least in big cities. Some places also have better-constructed buildings that retain heat better during the winter or stay cooler during the summer.”

According to the report, some progress is being made in increasing energy efficiency across the country. The U.S. Energy Information Administration expects 26 percent of electricity generation in 2026 will come from renewables. A number of them are being developed in the Houston area, including recent announcements like the Pleasure Island Power Collective in Port Arthur.

Still, Houston earned an abysmal ranking on WalletHub's greenest cities in the U.S. report earlier this year, coming in at No. 99 out of 100. Read more here.

Port Houston reports emissions progress as cargo volumes climb

greener growth

Port Houston’s initiatives to reduce emissions have shown some positive results, according to new data from the Port of Houston Authority.

Pulling from the Goods Movement Emissions Inventory (GMEI) report, which tracks port-related air emissions, Port Houston cited several improvements compared to the most recent report from 2019.

The port has seen total tonnage and container volumes increase by 16 percent and 28 percent, respectively, since 2019. However, greenhouse gas emissions have increased at a slower rate, growing only by 10 percent during the same time period, according to the data.

Additionally, emissions of nitrogen oxide fell by 7 percent, and emissions of particulate matter fell by 4 percent, despite adding 280 more pieces of cargo handling equipment.

“These results show that our emission-reduction efforts are working, and we are moving in the right direction,” Chairman Ric Campo said in a news release.

The Port Commission also recently approved items related to the $3 million U.S. Environmental Protection Agency Clean Ports Program (CPP) grant, which it received last year. The items will allow the port to work towards five new sustainability initiatives.

They include:

  1. An inventory of the port’s Scopes 1, 2, and 3 for greenhouse gas emissions
  2. A Port Area Climate Action Plan for the area and surrounding communities
  3. A CPP Truck Route Analysis
  4. Creation of the CPP Trucking Industry Collaborative
  5. Design of a customized website for Port of Houston Partners in Maritime Education, which is a non-profit leading maritime workforce development effort in local schools.

Port Houston aims to be carbon neutral by 2050.

Anning Corporation

Clean energy company Anning Corporation is working to develop geologic hydrogen, a natural carbon-free fuel, using its proprietary stimulation approaches and advanced exploration modeling. The company said that geologic hydrogen has the potential to be the lowest-cost source of reliable baseload electricity in the U.S.

The company was founded by CEO Sophie Broun in 2024 and is a member of Greentown Labs. Last month, it also announced that it was chosen to participate in Breakthrough Energy’s prestigious Fellows Program. Anning raised a pre-seed round this year and is currently raising a $6 million seed round.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTech Nexus LiftOff, and others. Lee is an Activate 2025 fellow.

Eclipse Energy

Previously known as Gold H2, Eclipse Energy converts end-of-life oil fields into low-cost, sustainable hydrogen sources. It completed its first field trial this summer, which demonstrated subsurface bio-stimulated hydrogen production. According to the company, its technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

Eclipse is a spinoff of Houston biotech company Cemvita. It was founded in 2022 by Moji Karimi (CEO and chairman of Cemvita), Prabhdeep Sekhon (CEO of Eclipse), Tara Karimi, and Rayyan Islam. The company closed an $8 million series A this year and has plans to raise another round in 2026.

Loop Bioproducts

Agricultural chemical manufacturing company Loop Bioproducts leverages the physiology of prickly pear cactus grown in Texas to produce bioenergy, food, and remediate industrial wastewater streams. The company uses its remote sensing technology, proprietary image-based machine learning model, and R&D innovation to capture raw biogas from the cactuses and is focused on scaling cactuses as an industrial crop on land.

Rhiannon Parker founded Loop Bioproducts in 2023.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and converts them into pure chemicals and fuels that are free of carbon emissions onsite, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ catalyst program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as chief scientist, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round earlier this year.
