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.

Maybe Don’t Rent an EV in Europe

There are lots of reasons why that might seem like a good idea, but I urge you to learn from my mistakes.

All I wanted was to drive an electric car to the solar eclipse. But after the third consecutive charging port RFID reader wouldn’t accept my credit card and finding that the employees inside the attached Spanish hotel restaurant mostly didn’t speak English, I began to feel as though, just maybe, this hadn’t been my best idea.

Opting for an EV as a rental car can be an attractive proposition. For a longtime electric driver like me, it’s the opportunity to avoid car emissions even when on holiday, and to try out the experience in another country. For others, it could be a way to save money while on vacation in countries with even more expensive gasoline than America’s, or perhaps to try out electric driving before taking the plunge on buying an EV back home.

Current conditions: Tropical Storm Moke sideswiped Hawaii yesterday just weeks after a weakened Hurricane Lala became the first major storm to hit the Big Island in decades • On the western fringe of the United States’ Pacific borders, Typhoon Saudel struck Guam and the Northern Mariana Islands over the weekend, bringing heavy rain and flooding • Temperatures in Khorramshahr, on Iran’s border with Iraq, are topping 118 degrees Fahrenheit, rendering the southwestern port city the hottest place on Earth.


THE TOP FIVE

1. Trump administration orders Arizona, California, and Nevada to cut water use

With water levels in reservoirs across the American West at record lows, the Trump administration has directed Arizona, California, and Nevada to cut back on how much water they use from the Colorado River over the next two years. On Friday, the Department of the Interior imposed the reductions via a series of documents detailing a two-year and a 10-year plan to salvage the supplies from the drought-stricken river fed by snowmelt from Colorado’s stretch of the Rocky Mountains. As climate change has shifted snow patterns, levels on the river have dropped. Yet the seven states that depend on the water — the aforementioned three in the Lower Basin, and Colorado, New Mexico, Utah, and Wyoming in the Upper Basin — could not come to agreement among themselves on how to divvy up the dwindling supply. Instead, the Interior Department came up with a proposal that forced the Lower Basin states to pare back first. As you may recall, Arizona’s Democratic governor called the cuts “draconian” when the administration released its proposal in early August. The plan, which imposes short-term cuts while leaving a larger split for later, sets the stage for what E&E News predicted would be “a behemoth legal fight.”

A Chat With Massachusetts’ First Heat Resilience Officer

The only other U.S. state to have a chief heat officer? Arizona.

The past three months will go down in the books as the hottest meteorological summer on record in Boston — but that is not a record that’s likely to stand long. At 3.5 degrees Fahrenheit of warming since 1970, Massachusetts has outpaced the national average by half a degree; by 2050, researchers expect the state will see more than two-dozen 90-plus-degree days every year. According to a 2023 climate report, that could result in as many as 400 excess deaths in the Commonwealth annually.

Now it’s someone’s job to do something about it. In mid-August, Massachusetts Governor Maura Healey announced the appointment of the state’s first heat resilience officer, making the Commonwealth only the second state in the country to have such a position — after the much more obvious choice, Arizona. (Healey is up for reelection this year, but the race is largely expected to be uncompetitive.) The inaugural role has gone to Katie Schlick, who most recently headed the resilience portfolio at the U.S. Climate Alliance and previously served as a special assistant to Ali Zaidi, the White House’s national climate advisor under Joe Biden.
