As Houstonians have been witnessing for the past few years, Memorial Park is in the midst of a renaissance, with a game-changing land bridge in the works, the recently opened Eastern Glades, and more than $200 million in improvements slated by 2028.

Now, Houston's crown green space has received another impressive donation towards the reintroduction of the native Gulf Coast prairie, courtesy of a $10 million contribution from the The Cyvia and Melvyn Wolff Family Foundation. The massive contribution will help the park's Land Bridge and Prairie project realize its innovative goals of establishing a more resilient ecology, enhancing animal habitats, improving storm water management, and providing a beautiful, immersive and accessible experience for Park visitors, according to a press release.

"The transformation of Memorial Park is vitally important to our city and our Foundation. We are honored to be part of this incredible effort and proud to join the Kinders and others who have funded the vision for the park," donor Cyvia Wolff said in a statement. "Together, we are creating one of the largest urban prairie reclamation efforts in Texas so that Houstonians can experience a native landscape that has largely been lost."

The multi-year project aims to restore 45 acres of native prairie to the park in an area that starts at the south basin of the land bridge and extends to an area north of Memorial Dr. For the time in more than a century, the land will look as it did when Indigenous people roamed the coastal plain — long before it was farmed by European settlers or served as the ground of Camp Logan, a training area for soldiers during World War I.

Once a dominant feature of coastal Texas and Louisiana, less than 1-percent of its historic range remains, according to the Memorial Park Conservancy. Seeds from plants found along the park's railroad tracks will be added to others collected by the Nature Conservancy to enable the project's realization.

One of the project's primary benefits will be making the park more resilient during floods. The new, south prairie basin will retain more water than the parking lots, woods, and baseball fields that occupied the area previously, while the prairie's deep root system will absorb more water that would otherwise wind up overwhelming Buffalo Bayou.

Increased biodiversity means that native species will return to the park for the first time. Its proximity to the park's Bayou Wilds forest should create more opportunities for bird watchers. Park visitors will be able to experience the prairie through trails and other paths that will connect to other areas of the park.

"Cyvia and Melvyn Wolff are an important part of the fabric of Houston with their leadership in business and education. It is a true honor for us to be working with the Wolff Foundation in returning to the park's ecological and cultural roots and to, quite literally, plant the seeds for Memorial Park's future," said Shellye Arnold, president and CEO of Memorial Park Conservancy. "Through thoughtful research, design, planting, and stewardship, this project will create new places for park visitors to enjoy, grow, and learn for years to come."

Houston park moves forward on innovative land bridge project

tunnel of sustainability

Few things get local greenspace lovers more hyped than the upcoming improvements and beautification of our beloved Memorial Park — which is currently undergoing a major transformation. While many of the updates and facelifts are years off, one of the most innovative ventures has reached a new milestone in the much-anticipated Land Bridge and Prairie project.

Installation of the first tunnel arches has started as of December 9, according to the Memorial Park Conservancy. Marked by two separate, 35-foot tall mounds, the Land Bridge will serve as a major connector for park users and wildlife between the north and south sides of the park, Additionally, it will offer new gathering spaces with scenic views of Houston and the project's expansive prairie network.

Once the project is completed, vehicular traffic will traverse a new alignment of Memorial Drive via tunnels through the Land Bridge — two tunnels below each of the mounds (one for each direction of travel), according to a press release. The arch segments now being erected south of existing Memorial Drive are for the two tunnels through the eastern-most mound.

Next up will be erection of the west mound arches; all tunnels are slated for completion and open to traffic by fall of 2021.

These tunnels boast an innovative edge. While most are built through existing hillsides or below ground, the Land Bridge tunnels will be set at the same grade as the existing roadway, prior to installation of the earthwork for the mounds, per a release. The tunnels through the east and west mound measure 400 feet and 560 feet long respectively and are made up of some 620 separate panels, each of which weighs just under 50,000 pounds.

While excitement is looming, traffic on Memorial Drive is no doubt a concern. Sources at Memorial Park Conservancy assure that Memorial will remain open throughout the duration of Land Bridge and Prairie construction. Within the project area, traffic has been reduced from three lanes to two each way.

All lanes will reopen in fall 2021 once the new Memorial Drive alignment through tunnels is complete. The new road alignment with three lanes restored each way will be complete in September 2021, while the Land Bridge is slated for substantial completion by October 2022.

Meanwhile, trees removed from the Land Bridge and Prairie project area (a major concern for locals) will be relocated in areas of the park designated for reforestation, or repurposed as either compost or toewood for streambank stabilization, in keeping with the Master Plan provisions.

UH researchers develop breakthrough material to boost efficiency of sodium-ion batteries

eyes on clean energy

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."

Texas A&M awarded $1.3M federal grant to develop clean energy tech from electronic waste

seeing green

Texas A&M University in College Station has received a nearly $1.3 million federal grant for development of clean energy technology.

The university will use the $1,280,553 grant from the U.S. Department of Energy to develop a cost-effective, sustainable method for extracting rare earth elements from electronic waste.

Rare earth elements (REEs) are a set of 17 metallic elements.

“REEs are essential components of more than 200 products, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions,” according to the Eos news website.

REEs also are found in defense equipment and technology such as electronic displays, guidance systems, lasers, and radar and sonar systems, says Eos.

The grant awarded to Texas A&M was among $17 million in DOE grants given to 14 projects that seek to accelerate innovation in the critical materials sector. The federal Energy Act of 2020 defines a critical material — such as aluminum, cobalt, copper, lithium, magnesium, nickel, and platinum — as a substance that faces a high risk of supply chain disruption and “serves an essential function” in the energy sector.

“DOE is helping reduce the nation’s dependence on foreign supply chains through innovative solutions that will tap domestic sources of the critical materials needed for next-generation technologies,” says U.S. Energy Secretary Jennifer Granholm. “These investments — part of our industrial strategy — will keep America’s growing manufacturing industry competitive while delivering economic benefits to communities nationwide.”
