Heat dome moves into Texas with record highs expected

A heat dome that has led to nearly 90 consecutive days of triple-digit temperatures in Phoenix moved into Texas Wednesday, with record highs expected to fall by the weekend, according to the National Weather Service.

Meanwhile, energy demand in Texas hit an unofficial all-time high Tuesday, according to data from the state’s grid operator.

A major heat alert is in place for Texas, reflecting what the weather service called “rare and/or long-duration extreme heat with little to no overnight relief.” An extreme heat alert was issued for eastern New Mexico.

A heat dome is a slow moving, upper-level high pressure system of stable air and a deep layer of high temperatures, meteorologist Bryan Jackson said.

“It is usually sunny, the sun is beating down, it is hot and the air is contained there,” Jackson said. “There are dozen or so sites that are setting daily records ... mostly over Texas.”

Record high temperatures were expected in cities such as Corpus Christi, San Antonio and Amarillo. In Phoenix, monsoon rains have provided brief respites since Sunday, although daytime highs continue to top 100 degrees Fahrenheit (37.8 degrees Celsius).

The dome was expected to move into western Oklahoma and eastern New Mexico beginning Saturday, then into the mid-Mississippi Valley, where it was forecast to weaken slightly, Jackson said.

About 14.7 million people are under an excessive heat warning, with heat indexes expected at 110 degrees Fahrenheit (43.3 degrees Celsius) and above. Another 10 million people were under a heat advisory.

There were 38 heat-related deaths in Texas from January through July, according to the Texas Department of State Health Services, and hundreds have already sought emergency care, according to MedStar ambulance in Fort Worth, Texas. The service responded to 286 heat-related calls during the first 20 days of August, about 14 per day, compared to about 11 per day in August 2023, according to public information officer Desiree Partain.

Austin-Travis County EMS Capt. Christa Stedman said calls about heat-related illness in the area around the Texas state Capitol since April 1 are up by about one per day compared with a year ago, though July was somewhat milder this year.

"The vast majority of what we see is heat exhaustion, which is good because we catch it before it’s heat stroke, but it’s bad because people are not listening to the red flags,” such as heat cramps in the arms, legs or stomach warning that the body is becoming too hot, Stedman said.

Despite the record heat in Texas, residents haven't been asked to cut back on their energy use like in years prior. This contrasts with the 11 conservation notices issued last year. One reason is that the agency, which manages Texas' independent energy grid and deregulated providers, has improved the grid's capabilities with the addition of more than 15 gigawatts of power supply since last summer.

Although the agency has gotten better at controlling the demands of the grid, their criteria for when to notify residents to conserve energy has also changed, Doug Lewin, an energy consultant and president of Stoic Energy said.

Lewin suspects it’s because they’re ineffective and unpopular.

“I don’t think they’re seeing all that much reduction when they give notices,” Lewin said of the Electric Reliability Council of Texas. In fact public uproar against the conservation warnings has led to the agency sending fewer of them, he continued.

“There are many factors that ERCOT operations take into consideration when determining the need to issue conservation, case by case depending on conditions at the time,” communications manager Trudi Webster said on the matter.

“It’s been a hot summer, but this one does stand out in terms of extremes,” said Jackson, the meteorologist.

Earlier this month, about 100 people were sickened and 10 were hospitalized due to extreme heat at a Colorado air show and at least two people have died due to the heat in California's Death Valley National Park.

Globally, a string of 13 straight months with a new average heat record came to an end this past July as the natural El Nino climate pattern ebbed, the European climate agency Copernicus announced Thursday.

Houston-based CO2 utilization company HYCO1 has signed a memorandum of understanding with Malaysia LNG Sdn. Bhd., a subsidiary of Petronas, for a carbon capture project in Malaysia, which includes potential utilization and conversion of 1 million tons of carbon dioxide per year.

The project will be located in Bintulu in Sarawak, Malaysia, where Malaysia LNG is based, according to a news release. Malaysia LNG will supply HYCO1 with an initial 1 million tons per year of raw CO2 for 20 years starting no later than 2030. The CCU plant is expected to be completed by 2029.

"This is very exciting for all stakeholders, including HYCO1, MLNG, and Petronas, and will benefit all Malaysians," HYCO1 CEO Gregory Carr said in the release. "We approached Petronas and MLNG in the hopes of helping them solve their decarbonization needs, and we feel honored to collaborate with MLNG to meet their Net Zero Carbon Emissions by 2050.”

The project will convert CO2 into industrial-grade syngas (a versatile mixture of carbon monoxide and hydrogen) using HYCO1’s proprietary CUBE Technology. According to the company, its CUBE technology converts nearly 100 percent of CO2 feed at commercial scale.

“Our revolutionary process and catalyst are game changers in decarbonization because not only do we prevent CO2 from being emitted into the atmosphere, but we transform it into highly valuable and usable downstream products,” Carr added in the release.

As part of the MoU, the companies will conduct a feasibility study evaluating design alternatives to produce low-carbon syngas.

The companies say the project is expected to “become one of the largest CO2 utilization projects in history.”

HYCO1 also recently announced that it is providing syngas technology to UBE Corp.'s new EV electrolyte plant in New Orleans. Read more here.
