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.”

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.”

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.”

Expert on powering Texas: The promise and challenges of renewable energy

Guest Column

Texas leads the nation in wind and solar energy, but that leadership is being tested as a surge in project cancellations raises new concerns about the future of renewables in the state.

While Texas clean energy has grown significantly in recent years, solar and wind often fall short of meeting peak electricity demand. As extreme weather, rising demand, and project cancellations strain the grid, Texas must confront the growing gap between renewable potential and real-time reliability.

Solar and Wind Energy

Solar generation in the Lone Star State has grown substantially over the past decade. The Texas solar industry is estimated to employ over 12,000 Texans and is contributing billions in local tax revenue and landowner income, and solar and storage are the largest sources of new energy on the Texas grid.

With a significant number of sunny days, Texas’ geography also enables it to be among the states with the greatest energy potential for solar power generation. Further moving to advance the use of solar energy generation, the 89th Texas legislature passed SB 1202 which accelerates the permitting process for home solar and energy storage installations. SB 1202 empowers homeowners to strengthen their own energy security and supports greater grid resilience across the state.

Texas has also led the United States in wind energy production for more than 17 years, with 239 wind-related projects and over 15,300 wind turbines, which is more than any other state. The economic impact of wind energy in Texas is substantial, with the industry contributing $1.7 billion a year to the state’s gross domestic product. With wind electric power generation jobs offering an average annual wage of $109,826, the growing sector provides lucrative employment opportunities.

However, solar and wind currently struggle to meet Texas’ peak electricity demand from 5 pm to 7 pm — a time when millions of residents return home, temperatures remain high and air conditioner use surges. Solar generation begins to decline just as demand ramps up, and wind production is often inconsistent during these hours. Without sufficient long-duration storage or dispatchable backup power, this mismatch between supply and demand presents a significant reliability risk — one that becomes especially urgent during heat waves and extreme weather events, as seen during ERCOT conservation alerts.

Geothermal Energy

Geothermal energy uses heat from beneath the Earth’s surface to provide reliable, low-emission power with minimal land use and no fuel transport. Though it currently supplies a small share of energy, Texas is emerging as a leader in its development, supported by state leaders, industry, and environmentalists. During the 89th legislative session, Texas passed HB 3240 to create a Geothermal Energy Production Policy Council, set to begin work on September 1, 2025.

In 2024, Sage Geosystems was selected to develop geothermal projects at the Naval Air Station in Corpus Christi, expanding its work with the Department of Defense. In partnership with the Environmental Security Technology Certification Program, Sage is using its proprietary Geopressured Geothermal Systems technology to evaluate the potential for geothermal to be a source of clean and consistent energy at the base.

One limitation of geothermal energy is location. Deep drilling is costly, and areas with high water tables, like some coastal regions, may not be viable.

Hydroelectric Energy

While hydropower plays a minor role in Texas’ energy mix, it is still an essential energy source. Its output depends on water availability, which can be affected by seasonal and long-term changes like droughts.

Texas has 26 hydropower plants with a total capacity of nearly 738 megawatts, serving about 2.9 million people as of 2019. Harris County holds 43% of all hydropower generation jobs in the state, and in 2021, hydroelectric power generation contributed $700 million to Texas’ gross domestic product.

Federal funding is helping expand hydropower in Texas. The Southwestern Power Administration has committed about $103 million to support infrastructure, including $32 million for upgrades to Central Texas’s Whitney Dam. The 2021 Inflation Reduction Act added $369 billion in tax credits for clean energy, supporting dam retrofits nationwide. In 2022, the Department of Energy launched over $28 million in new funding through the Infrastructure Law to help meet national clean energy goals by 2035 and carbon neutrality by 2050.

Tidal Energy

Driven by the moon and sun, tidal energy is predictable but limited to coastal areas with strong tides. Although Texas has modest tidal potential, research is ongoing to optimize it. Texas A&M University is developing a floating test platform for hybrid renewable systems, integrating tidal, wave, wind, and solar energy. In addition, St. Mary’s University in San Antonio is prototyping small-scale tidal turbines using 3D printing technology.

While commercial tidal power remains in the research phase, the state’s offshore capabilities, engineering talent, and growing university-led innovation could make it a player in hybrid marine renewable systems. Floating platforms that integrate wave, tide, solar, and wind offer a compelling vision for offshore power generation suited to Texas’ unique coastal conditions.

Biomass Energy

Biomass energy is the largest renewable source worldwide, providing 55% of renewables and over 6% of global energy. While reliable, it can be less efficient, sometimes using more energy to burn the organic matter than it produces, and demand may exceed supply.

In Texas, biomass is a nominal part of the state’s energy portfolio. However, substantial research is being conducted by Texas A&M University to attempt to convert algae and food waste into a cost-efficient source of biomass material. In addition, UK-based biomass and renewable energy company Drax opened its North American headquarters in Houston, which created more than 100 new jobs in Texas’ renewable energy industry.

It’s clear that renewable energy is playing an increasingly important role in shaping Texas’ energy future. But the road ahead demands a realistic view: while these sources can reduce emissions and diversify our generation mix, they do not yet solve for peak load reliability — especially during the critical 5 pm to 7 pm window when grid stress is highest.

Meeting that challenge will require not just investment in renewables, but also innovation in grid-scale storage, flexible generation, market reform and consumer programs. A diversified, resilient energy portfolio — one that includes renewables and reliable dispatchable sources — will be the key to ensuring that Texas remains powered, prepared and prosperous for generations to come.

Shell to shut down Volta EV charging business with 2,000 stations

pulling the plug

A little over two years after buying it for $169 million, Houston-based Shell USA is shutting down its Volta C electric vehicle charging business.

Shell confirmed to AdExchanger that it will dismantle Volta’s network of more than 2,000 EV charging stations this year. A Shell spokesperson said the energy giant is turning its attention to high-speed public charging stations at Shell-branded sites like gas stations and standalone EV hubs.

Around the world, Shell operates more than 70,000 public EV charging stations. In 2024, the company said it was aiming for a global total of about 200,000 charging stations by 2030.

When Shell announced in March 2023 that it had completed its acquisition of Volta, the energy company said it was gaining an EV charging network with more than 3,000 charging stations at places such as shopping centers, grocery stores and pharmacies.

Shell had said that although Volta’s revenue came from advertising on screens at EV charging stations, it planned to increase the number of charging stations that required motorists to pay for power.

Shell explored a sale of the Volta business earlier this year but didn’t find a buyer, according to AdExchanger.

ExxonMobil may delay or cancel plans for $7 billion Baytown hydrogen plant

project uncertainty

Spring-based ExxonMobil, the country’s largest oil and gas company, might delay or cancel what would be the world’s largest low-carbon hydrogen plant due to a significant change in federal law. The project carries a $7 billion price tag.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” ExxonMobil Chairman and CEO Darren Woods said during the company’s recent second-quarter earnings call.

Woods said ExxonMobil is working to determine whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit will help pave the way for a “broader” low-carbon hydrogen market.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods said.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

Woods said ExxonMobil is trying to nail down sales contracts connected to the project, including exports of ammonia to Asia and Europe and sales of hydrogen in the U.S.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

As it stands now, ExxonMobil wants the Baytown plant to produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The company has said the project could store as much as 10 million metric tons of CO2 per year.
