Warning: Houston could be in for an especially uncomfortable summer.

A new study from solar energy company Wolf River Electric puts Texas at No. 2 among the states most at risk for power outages this summer. Michigan tops the list.

Wolf River Electric analyzed the number of large-scale outages that left more than 5,000 utility customers, including homes, stores and schools, without summertime electricity from 2019 to 2023. During that period, Texas experienced 7,164 summertime power outages.

Despite Michigan being hit with more summertime outages, Texas led the list of states with the most hours of summertime power outages — an annual average of 35,440. That works out to 1,477 days. “This means power cuts in Texas tend to last longer, making summer especially tough for residents and businesses,” the study says.

The Electric Reliability Council of Texas (ERCOT), which operates the electric grid serving 90 percent of the state, predicts its system will set a monthly record for peak demand this August — 85,759 megawatts. That would exceed the current record of 85,508 megawatts, dating back to August 2023.

In 2025, natural gas will account for 37.7 percent of ERCOT’s summertime power-generating capacity, followed by wind (22.9 percent) and solar (19 percent), according to an ERCOT fact sheet.

This year, ERCOT expects four months to surpass peak demand of 80,000 megawatts:

June 2025 — 82,243 megawatts
July 2025 — 84,103 megawatts
August 2025 — 85,759 megawatts
September 2025 — 80,773 megawatts

One megawatt is enough power to serve about 250 residential customers amid peak demand, according to ERCOT. Using that figure, the projected peak of 85,759 megawatts in August would supply enough power to serve more than 21.4 million residential customers in Texas.

Data centers, artificial intelligence and population growth are driving up power demand in Texas, straining the ERCOT grid. In January, ERCOT laid out a nearly $33 billion plan to boost power transmission capabilities in its service area.

Woodlands company licenses free patents to ERCOT to boost grid reliability

grid deal

Lancium, a company based in The Woodlands that specializes in infrastructure for connecting large-scale data centers to power grids, is licensing a portfolio of patents to the Electric Reliability Council of Texas (ERCOT) at no cost.

In a news release, Lancium says the intellectual property agreement “ensures ERCOT can sublicense these patents freely, thereby expanding market participation opportunities without risk of patent infringement disputes.”

“This agreement exemplifies Lancium’s dedication to supporting grid stability and innovation across the ERCOT region,” Michael McNamara, CEO of Lancium, said in a news release. “While these patents represent significant technological advancements, we believe that enabling ERCOT and its market participants to operate freely is more valuable for the long-term reliability and resilience of the Texas grid.”

The licensed patents encompass Lancium technologies that support load resources in ERCOT’s market, which covers about 90 percent of Texas. Specifically, the patents deal with controllable load resources. A controlled load resource allows ERCOT and other grids to increase or decrease power consumption during peak periods or emergencies.

ERCOT predicts power demand in Texas will nearly double by 2030, “in part due to more requests to plug into the grid from large users like data centers, crypto mining facilities, hydrogen production plants, and oil and gas companies,” The Texas Tribune reported.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
