As AI data centers spring up across the country, their energy demand and resulting greenhouse gas emissions are raising concerns. With servers and energy-intensive cooling systems constantly running, these buildings can use anywhere from a few megawatts of power for a small data center to more than 100 megawatts for a hyperscale data center. To put that in perspective, the average large natural gas power plant built in the U.S. generates less than 1,000 megawatts. When the power for these data centers comes from fossil fuels, they can become major sources of climate-warming emissions in the atmosphere—unless the power plants capture their greenhouse gases first and then lock them away. Google recently entered into a unique corporate power purchase agreement to support the construction of a natural gas power plant in Illinois designed to do exactly that through carbon capture and storage. So how does carbon capture and storage, or CCS, work for a project like this? I am an engineer who wrote a 2024 book about various types of carbon storage. Here’s the short version of what you need to know. How CCS works When fossil fuels are burned to generate electricity, they release carbon dioxide, a powerful greenhouse gas that remains in the atmosphere for centuries. As these gases accumulate in the atmosphere, they act like a blanket, holding heat close to the Earth’s surface. Too high of a concentration heats up the Earth too much, setting off climate changes, including worsening heat waves, rising sea levels, and intensifying storms. Carbon capture and storage involves capturing carbon dioxide from power plants, industrial processes, or even directly from the air and then transporting it, often through pipelines, to sites where it can be safely injected underground for permanent storage. The carbon dioxide might be transported as a supercritical gas—which is right at the phase change from liquid to gas and has the properties of both—or dissolved in a liquid. Once injected deep underground, the carbon dioxide can become permanently trapped in the geologic structure, dissolve in brine, or become mineralized, turning it to rock. The goal of carbon storage is to ensure that carbon dioxide can be kept out of the atmosphere for a long time. Types of underground carbon storage There are several options for storing carbon dioxide underground. Depleted oil and natural gas reservoirs have plentiful storage space and the added benefit that most are already mapped and their limits understood. They already held hydrocarbons in place for millions of years. Carbon dioxide can also be injected into working oil or gas reservoirs to push out more of those fossil fuels while leaving most of the carbon dioxide behind. This method, known as enhanced oil and gas recovery, is the most common one used by carbon capture and storage projects in the U.S. today, and one reason CCS draws complaints from environmental groups. Volcanic basalt rock and carbonate formations are considered good candidates for safe and long-term geological storage because they contain calcium and magnesium ions that interact with carbon dioxide, turning it into minerals. Iceland pioneered this method using its bedrock of volcanic basalt for carbon storage. Basalt also covers most of the oceanic crust, and scientists have been exploring the potential for sub-seafloor storage reservoirs. How Iceland uses basalt to turn captured carbon dioxide into solid minerals. In the U.S., a fourth option likely has the most potential for industrial carbon dioxide storage—deep saline aquifers, which is what Google plans to use. These widely distributed aquifers are porous and permeable sediment formations consisting of sandstone, limestone, or dolostone. They’re filled with highly mineralized groundwater that cannot be used directly for drinking water but is very suitable for storing CO2. Deep saline aquifers also have large storage capacities, ranging from about 1,000 to 20,000 gigatons. In comparison, the nation’s total carbon emissions from fossil fuels in 2024 were about 4.9 gigatons. As of fall 2025, 21 industrial facilities across the U.S. used carbon capture and storage, including industries producing natural gas, fertilizer, and biofuels, according to the Global CCS Institute’s 2025 report. Five of those use deep saline aquifers, and the rest involve enhanced oil or gas recovery. Eight more industrial carbon capture facilities were under construction. Google’s plan is unique because it involves a power purchase agreement that makes building the power plant with carbon capture and storage possible. Google’s deep saline aquifer storage plan Google’s 400-megawatt natural gas power plant, to be built with Broadwing Energy, is designed to capture about 90% of the plant’s carbon dioxide emissions and pipe them underground for permanent storage in a deep saline aquifer in the nearby Mount Simon sandstone formation. The Mount Simon sandstone formation is a huge saline aquifer that lies underneath most of Illinois, southwestern Indiana, southern Ohio, and western Kentucky. It has a layer of highly porous and permeable sandstone that makes it an ideal candidate for carbon dioxide injection. To keep the carbon dioxide in a supercritical state, that layer needs to be at least half a mile (800 meters) deep. A thick layer of Eau Claire shale sits above the Mount Simon formation, serving as the caprock that helps prevent stored carbon dioxide from escaping. Except for some small regions near the Mississippi River, Eau Claire shale is considerably thick—more than 300 feet (90 meters)—throughout most of the Illinois basin. The estimated storage capacity of the Mount Simon formation ranges from 27 gigatons to 109 gigatons of carbon dioxide. The Google project plans to use an existing injection well site that was part of the first large-scale carbon storage demonstration in the Mount Simon formation. Food producer Archer Daniels Midland began injecting carbon dioxide there from nearby corn processing plants in 2012. Carbon capture and storage has had challenges as the technology developed over the years, including a pipeline rupture in 2020 that forced evacuations in Satartia, Mississippi, and caused several people to lose consciousness. After a recent leak deep underground at the Archer Daniels Midland site in Illinois, the Environmental Protection Agency in 2025 required the company to improve its monitoring. Stored carbon dioxide had migrated into an unapproved area, but no threat to water supplies was reported. Why does CCS matter? Data centers are expanding quickly, and utilities will have to build more power capacity to keep up. The artificial intelligence company OpenAI is urging the U.S. to build 100 gigawatts of new capacity every year—doubling its current rate. Many energy experts, including the International Energy Agency, believe carbon capture and storage will be necessary to slow climate change and keep global temperatures from reaching dangerous levels as energy demand rises.

The Energy Department plans to award up to $6 billion across 33 projects to wring carbon dioxide from heavy industries like metals, chemicals, and cement.Why it matters: It's the "single largest industrial decarbonization investment in American history," DOE boss Jennifer Granholm told reporters.Industrial processes create roughly a fourth of U.S. CO2 emissions — and even close to a third — depending on how you slice the national pie.It's also the Biden administration's latest in a multi-pronged effort to tame domestic carbon emissions.State of play: The projects are funded largely through the Democrats' 2022 climate law, with some cash from the 2021 bipartisan infrastructure law, too.They would together provide yearly emissions cuts that match the annual CO2 output of 3 million gasoline-powered cars, the agency estimates.It's a federal cost-share with companies, so officials see over $20 billion in total investment.Monday's announcement also touts efforts to use union labor and tackle environmental justice — both key Democratic policy priorities.Data: Rhodium Group; Chart: Axios VisualsThe big picture: Making heavy industries climate-friendly is a tough nut to crack, as these sectors often need massive energy inputs and extremely high heat. And unlike the electricity system, a similarly large CO2 source, solutions are often lacking at commercial scale.Zoom in: Examples of the 33 projects include...Converting a Constellium aluminum plant in West Virginia to use furnaces that can run on cleaner fuels including hydrogen.Installing a CO2 capture and storage system at a Heidelberg Materials cement plant in Indiana.Slashing process heat emissions from Kraft Heinz facilities in nine states by using various electrification technologies.Yes, but: These are initial decisions subject to more grant negotiations. And if funded, a project faces "go/no-go" decision points at various phases, where the agency weighs progress and community benefits.What's next: Officials hope this spurs use of cleaner tech in these industries more widely — in the U.S. and worldwide."The solutions that we are funding are replicable, and they're scalable," Granholm said.

Deep below the ocean surface, the light fades into a twilight zone where whales and fish migrate and dead algae and zooplankton rain down from above. This is the heart of the ocean’s carbon pump, part of the natural ocean processes that capture about a third of all human-produced carbon dioxide and sink it into the deep sea, where it remains for hundreds of years. There may be ways to enhance these processes so the ocean pulls more carbon out of the atmosphere to help slow climate change. Yet little is known about the consequences. Peter de Menocal, a marine paleoclimatologist and director of Woods Hole Oceanographic Institution, discussed ocean carbon dioxide removal at a recent TEDxBoston: Planetary Stewardship event. In this interview, he dives deeper into the risks and benefits of human intervention and describes an ambitious plan to build a vast monitoring network of autonomous sensors in the ocean to help humanity understand the impact. First, what is ocean carbon dioxide removal, and how does it work in nature? The ocean is like a big carbonated beverage. Although it doesn’t fizz, it has about 50 times more carbon than the atmosphere. So, for taking carbon out of the atmosphere and storing it someplace where it won’t continue to warm the planet, the ocean is the single biggest place it can go. Ocean carbon dioxide removal, or ocean CDR, uses the ocean’s natural ability to take up carbon on a large scale and amplifies it. Carbon gets into the ocean from the atmosphere in two ways. In the first, air dissolves into the ocean surface. Winds and crashing waves mix it into the upper half-mile or so, and because seawater is slightly alkaline, the carbon dioxide is absorbed into the ocean. The second involves the biologic pump. The ocean is a living medium—it has algae and fish and whales, and when that organic material is eaten or dies, it gets recycled. It rains down through the ocean and makes its way to the ocean twilight zone, a level around 650 to 3300 feet (roughly 200 to 1,000 meters) deep. The ocean twilight zone sustains biologic activity in the oceans. It is the “soil” of the ocean where organic carbon and nutrients accumulate and are recycled by microbes. It is also home to the largest animal migration on the planet. Each day trillions of fish and other organisms migrate from the depths to the surface to feed on plankton and one another, and go back down, acting like a large carbon pump that captures carbon from the surface and shunts it down into the deep oceans where it is stored away from the atmosphere. Why is ocean CDR drawing so much attention right now? The single most shocking sentence I have read in my career was in the Intergovernmental Panel on Climate Change’s Sixth Assessment Report, released in 2021. It said that we have delayed action on climate change for so long that removing carbon dioxide from the atmosphere is now necessary for all pathways to keep global warming under 1.5 degrees Celsius (2.7 F). Beyond that, climate change’s impacts become increasingly dangerous and unpredictable. Because of its volume and carbon storage potential, the ocean is really the only arrow in our quiver that has the ability to take up and store carbon at the scale and urgency required. A 2022 report by the national academies outlined a research strategy for ocean carbon dioxide removal. The three most promising methods all explore ways to enhance the ocean’s natural ability to take up more carbon. The first is ocean alkalinity enhancement. The oceans are salty—they’re naturally alkaline, with a pH of about 8.1. Increasing alkalinity by dissolving certain powdered rocks and minerals makes the ocean a chemical sponge for atmospheric CO2. A second method adds micronutrients to the surface ocean, particularly soluble iron. Very small amounts of soluble iron can stimulate greater productivity, or algae growth, which drives a more vigorous biologic pump. Over a dozen of these experiments have been done, so we know it works. Third is perhaps the easiest to understand—grow kelp in the ocean, which captures carbon at the surface through photosynthesis, then bale it and sink it to the deep ocean. But all of these methods have drawbacks for large-scale use, including cost and unanticipated consequences. I’m not advocating for any one of these, or for ocean CDR more generally. But I do believe accelerating research to understand the impacts of these methods is essential. The ocean is essential for everything humans depend on—food, water, shelter, crops, climate stability. It’s the lungs of the planet. So we need to know if these ocean-based technologies to reduce carbon dioxide and climate risk are viable, safe and scalable. You’ve talked about building an ‘internet of the ocean’ to monitor changes there. What would that involve? The ocean is changing rapidly, and it is the single biggest cog in Earth’s climate engine, yet we have almost no observations of the subsurface ocean to understand how these changes are affecting the things we care about. We’re basically flying blind at a time when we most need observations. Moreover, if we were to try any of these carbon removal technologies at any scale right now, we wouldn’t be able to measure or verify their effectiveness or assess impacts on ocean health and ecosystems. So, we are leading an initiative at Woods Hole Oceanographic Institution to build the world’s first internet for the ocean, called the Ocean Vital Signs Network. It’s a large network of moorings and sensors that provides 4D eyes on the oceans—the fourth dimension being time—that are always on, always connected to monitor these carbon cycling processes and ocean health. Right now, there is about one ocean sensor in the global Argo program for every patch of ocean the size of Texas. These go up and down like pogo sticks, mostly measuring temperature and salinity. We envision a central hub in the middle of an ocean basin where a dense network of intelligent gliders and autonomous vehicles measure ocean properties including carbon and other vital signs of ocean and planetary health. These vehicles can dock, repower, upload data they’ve collected and go out to collect more. The vehicles would be sharing information and making intelligent sampling decisions as they measure the chemistry, biology and environmental DNA for a volume of the ocean that’s really representative of how the ocean works. Having that kind of network of autonomous vehicles, able to come back in and power up in the middle of the ocean from wave or solar or wind energy at the mooring site and send data to a satellite, could launch a new era of ocean observing and discovery. Does the technology needed for this level of monitoring exist? We’re already doing much of this engineering and technology development. What we haven’t done yet is stitch it all together. For example, we have a team that works with blue light lasers for communicating in the ocean. Underwater, you can’t use electromagnetic radiation as cellphones do, because seawater is conductive. Instead, you have to use sound or light to communicate underwater. An acoustics communications group works on swarming technologies and communications between nearby vehicles. Another group works on how to dock vehicles into moorings in the middle of the ocean. Another specializes in mooring design. Another is building chemical sensors and physical sensors that measure ocean properties and environmental DNA. An experiment in the North Atlantic called the Ocean Twilight Zone Project will image the larger functioning of the ocean over a big piece of real estate at the scale at which ocean processes actually work. We’ll have acoustic transceivers that can create a 4D image over time of these dark, hidden regions, along with gliders, new sensors we call “minions” that will be looking at ocean carbon flow, nutrients and oxygen changes. “Minions” are basically sensors the size of a soda bottle that go down to a fixed depth, say 1,000 meters (0.6 miles), and use essentially an iPhone camera pointing up to take pictures of all the material floating down through the water column. That lets us quantify how much organic carbon is making its way into this old, cold deep water, where it can remain for centuries. For the first time we’ll be able to see just how patchy productivity is in the ocean, how carbon gets into the ocean and if we can quantify those carbon flows. That’s a game-changer. The results can help establish the effectiveness and ground rules for using CDR. It’s a Wild West out there—nobody is watching the oceans or paying attention. This network makes observation possible for making decisions that will affect future generations. Do you believe ocean CDR is the right answer? Humanity doesn’t have a lot of time to reduce carbon emissions and to lower carbon dioxide concentrations in the atmosphere. The reason scientists are working so diligently on this is not because we’re big fans of CDR, but because we know the oceans may be able to help. With an ocean internet of sensors, we can really understand how the ocean works including the risks and benefits of ocean CDR.

Grand schemes, many backed by government, masquerade as taking action on the environment. They should be disownedLet’s talk about perceptionware. Perceptionware is technology whose main purpose is to create an impression of action. Whether it will ever work at scale is less important, in some cases entirely beside the point. If it reassures the public and persuades government not to regulate damaging industries, that’s mission accomplished.Managing perceptions is an expensive business. Real money, especially public money, is spent on fake solutions. Take carbon capture and storage: catching and burying carbon dioxide emissions from power stations, oil and gas fields, and steel and cement plants. For 20 years, it has spectacularly failed to reduce greenhouse gas emissions. In fact, its only clear successes involve enhanced oil recovery: carbon dioxide is used to drive oil out of geological formations that are otherwise difficult to exploit. With astonishing chutzpah, some oil companies have claimed the small amount of carbon that remains trapped in the rocks as a climate benefit. Though it is greatly outweighed by the extra oil extracted, they have, as a result, received billions in government subsidies. Continue reading...
