Geothermal Energy Storage is Making a Big Leap in Texas

On the EarthStore project, nuclear-powered ships, and plastic pollution.

Current conditions: Hurricane Ernesto could strengthen into a category 3 storm by Friday • Several days of heavy rain in Majorca, Spain, flooded streets and grounded flights • The heat index is hovering around 115 degrees Fahrenheit for parts of Arkansas, Louisiana, and Mississippi.

THE TOP FIVE

1. Texas to host first grid-connected geothermal energy storage project

Plans are underway in Texas to build what will become the first geothermal energy storage project to deliver power to the grid. The 3-megawatt EarthStore project will be located in Christine, Texas, and operated by Sage Geosystems. It will connect with the ERCOT grid, storing energy to be deployed on demand. Advanced geothermal reservoirs harness the heat under the Earth’s surface to generate energy. They can store power that’s been generated by wind or solar in the form of hot water or steam, and some research suggests this process could be more efficient and perhaps cheaper than using batteries. Either way, as renewable capacity ramps up, the more storage options, the better. The project is expected to be ready by the end of 2024.

2. Greece assesses damage from wildfire near Athens

The wildfire on the outskirts of Athens this week burned 40 square miles of land, or an area about twice the size of Manhattan, according to satellite data from the Copernicus Emergency Management Service. One person was killed and at least 78 homes were lost to the flames. Intense drought conditions, combined with soaring temperatures, have turned Greece into a tinderbox, with more than 3,500 fires ignited since May, up nearly 50% from the same period last year. More than one-third of the forests surrounding Athens have been scorched by wildfires over the last eight years.

3. Report: U.S. will back global plastics treaty

The U.S. will support a United Nations treaty to cap the amount of new plastic produced annually, Reuters reported. America is one of the world’s most prolific plastic makers, and has previously supported the idea that each country should be able to manage its own production. But many other nations have called for limiting and phasing down new plastic production to curb pollution and toxic chemicals, an initiative the U.S. seems to be warming to. Most plastics are made from fossil fuels, and major producers like China and Saudi Arabia have argued that the focus should be on recycling and reusing, instead of limiting production overall. The final talks over the UN plastics treaty are scheduled for November.

4. Maersk joins initiative to study nuclear-powered ships

Danish shipping giant Maersk is interested in studying the feasibility of nuclear-powered cargo ships. The company will team up with maritime services firm Lloyd’s Register and Core Power to figure out how a nuclear reactor could be fitted on a vessel, plus what kinds of safety precautions and regulations would need to be in place. “Nuclear power holds a number of challenges related to for example safety, waste management, and regulatory acceptance across regions, and so far, the downsides have clearly outweighed the benefits of the technology,” Ole Graa Jakobsen, Maersk’s head of fleet technology, said in a statement. “If these challenges can be addressed by development of the new so-called fourth-generation reactor designs, nuclear power could potentially mature into another possible decarbonization pathway for the logistics industry 10 to 15 years in the future,” he said. The shipping sector accounts for about 3% of global carbon dioxide emissions, and guidelines from the International Maritime Organization set out in 2023 require companies to cut emissions by 40% by 2030.

5. China’s OceanX floating wind turbine reaches wind farm

This week a giant, two-headed, floating offshore wind turbine has been on a 50-hour, 191-nautical-mile journey from Guangzhou, China, to its final destination in the Qingzhou IV Offshore Wind Farm in Yangjiang. Yesterday it finally arrived safely. The OceanX is the world’s largest floating wind turbine platform in terms of capacity. The company behind it, Mingyang Smart Energy, says the platform can produce 54 million kWh annually, enough to power 30,000 households. It’s made to be used in deep water and the company says it can withstand the kind of high winds and waves generated by typhoons.

THE KICKER

New analysis finds that enacting the policies outlined in the conservative blueprint Project 2025 would result in 1.7 million fewer jobs, 2,000 pollution-related premature deaths, and boost U.S. emissions by about 780 million metric tons per year by 2030.

How a Giant Solar Farm Flopped in Rural Texas

Amarillo-area residents successfully beat back a $600 million project from Xcel Energy that would have provided useful tax revenue.

Power giant Xcel Energy just suffered a major public relations flap in the Texas Panhandle, scrubbing plans for a solar project amidst harsh backlash from local residents.

On Friday, Xcel Energy withdrew plans to build a $600 million solar project right outside of Rolling Hills, a small, relatively isolated residential neighborhood just north of the city of Amarillo, Texas. The project was part of several solar farms it had proposed to the Texas Public Utilities Commission to meet the load growth created by the state’s AI data center boom. As we’ve covered in The Fight, Texas should’ve been an easier place to do this, and there were few if any legal obstacles standing in the way of the project, dubbed Oneida 2. It was sited on private lands, and Texas counties lack the sort of authority to veto projects you’re used to seeing in, say, Ohio or California.

A Data Center Is Dead, Long Live a Solar Farm

And more of the most important news about renewable projects fighting it out this week.

The United States.

1. Racine County, Wisconsin – Microsoft is scrapping plans for a data center after fierce opposition from a host community in Wisconsin.

  • The town of Caledonia was teed up to approve land rezoning for the facility, which would’ve been Microsoft’s third data center in the state. Dubbed “Project Nova,” the data center would have sat near an existing We Energies natural gas power plant.
  • After considerable pushback at community meetings, the tech giant announced Friday that it would either give up on the project or relocate it elsewhere to avoid more fervent opposition.
  • “While we have decided not to proceed with this particular site, we remain fully committed to investing in Southeast Wisconsin. We view this as a healthy step toward building a project that aligns with community priorities and supports shared goals,” Microsoft said in a statement published to its website, adding that it will attempt to “identify a site that supports both community priorities and our long-term development objectives.”
  • A review of the project opponents’ PR materials shows their campaign centered on three key themes: the risk of higher electricity bills, environmental impacts of construction and traffic, and a lack of clarity around how data centers could be a public good. Activists also frequently compared Project Nova to a now-infamous failed project in Wisconsin from the Chinese tech manufacturer Foxconn.

2. Rockingham County, Virginia – Another day, another chokepoint in Dominion Energy’s effort to build more solar energy to power surging load growth in the state, this time in the quaint town of Timberville.

How the AI Boom Could Come Back Around for Natural Gas

A conversation with Enchanted Rock’s Joel Yu.

The Fight Q & A subject.

This week’s chat was with Joel Yu, senior vice president for policy and external affairs at the data center micro-grid services company Enchanted Rock. Now, Enchanted Rock does work I usually don’t elevate in The Fight – gas-power tracking – but I wanted to talk to him about how conflicts over renewable energy are affecting his business, too. You see, when you talk to solar or wind developers about the potential downsides in this difficult economic environment, they’re willing to be candid … but only to a certain extent. As I expected, someone like Yu who is separated enough from the heartburn that is the Trump administration’s anti-renewables agenda was able to give me a sober truth: Land use and conflicts over siting are going to advantage fossil fuels in at least some cases.

The following conversation was lightly edited for clarity.
