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.

Current conditions: A Pineapple Express — the powerful atmospheric river that hits the West Coast, not the marijuana strain — could pummel the Southwest with heavy rain on Halloween • The remnants of Typhoon Champi are driving a severe storm in the Bering Sea, with four-foot waves lapping on Alaska’s shore • Despite India’s evacuation of nearly 200,000 people, Cyclone Arnab killed at least nine and destroyed tens of thousands of acres of crops in Andhra Pradesh.


THE TOP FIVE

1. The Fed holds rates steady

The Federal Reserve voted Wednesday to keep benchmark interest rates steady despite last month’s spike in inflation statistics. In a post-meeting statement, the Federal Open Market Committee said it had decided to keep the federal funds target range between 3.75% and 4%, maintaining the central bank’s quarter percentage-point hike from last month. “Inflation remains elevated,” the statement cautioned. “The accumulation of more information will help the Committee determine the policy stance appropriate to ensure a timely return of inflation to the Committee’s 2% goal.”

Why Permitting Reform Is a Historic Victory Over Utilities

Rob talks with David Pomerantz, the executive director of the Energy and Policy Institute, about how the bill would remake the electricity grid — and strike against utiities’ political power.

Climate and environmental advocates are sharply divided over the Senate’s bipartisan permitting reform proposal. But what most people agree is that the bill’s changes to electricity and transmission law are really, really good — and in some sense are much better than expected.

Because of how the media works, that means nobody has talked about these proposals very much. So on this show, we wanted to focus on the part of the Bipartisan American Affordability and Jobs Act that has gotten rave reviews.
