The CO2 that is extracted from the water is run through a purification process that uses activated carbon in the form of charred coconut husks, and is then ready to be stored.

In a scaled up system, it would be fed into geological CO2 storage. Before the water is released, its acidity is restored to normal levels, making it ready to absorb more carbon dioxide from the air.

“This discharged water that now has very low carbon concentrations needs to refill it, so it’s just trying to suck CO2 from anywhere, and it sucks it from the atmosphere,” says Halloran. “A simple analogy is that we’re squeezing out a sponge and putting it back.”

While more tests are needed to understand the full potential of the technology, Halloran admits that it doesn’t “blow direct air capture out the water in terms of the energy costs,” and there are other challenges such as having to remove impurities from the water before releasing it, as well as the potential impact on ecosystems. But, he adds, all carbon capture technologies incur high costs in building plants and infrastructure, and using seawater has one clear advantage: It has a much higher concentration of carbon than air does, “so you should be able to really reduce the capital costs involved in building the plants.”

Mitigating impacts
One major concern with any system that captures carbon from seawater is the impact of the discharged water on marine ecosystems. Guy Hooper, a PhD researcher at the University of Exeter, who’s working on this issue at the SeaCURE site, says that low-carbon seawater is released in such small quantities that it is unlikely to have any effect on the marine environment, because it dilutes extremely quickly.

However, that doesn’t mean that SeaCURE is automatically safe. “To understand how a scaled-up version of SeaCURE might affect the marine environment, we have been conducting experiments to measure how marine organisms respond to low-carbon seawater,” he adds. “Initial results suggest that some marine organisms, such as plankton and mussels, may be affected when exposed to low-carbon seawater.”

To mitigate potential impacts, the seawater can be “pre-diluted” before releasing it into the marine environment, but Hooper warns that a SeaCURE system should not be deployed near any sensitive marine habitats.

There is rising interest in carbon capture from seawater — also known as Direct Ocean Capture or DOC — and several startups are operating in the field. Among them is Captura, a spin off from the California Institute of Technology that is working on a pilot project in Hawaii, and Amsterdam-based Brineworks, which says that its method is more cost-effective than air carbon capture.
According to Stuart Haszeldine, a professor of Carbon Capture and Storage at the University of Edinburgh, who’s not involved with SeaCURE, although the initiative appears to be more energy efficient than current air capture pilot tests, a full-scale system will require a supply of renewable energy and permanent storage of CO2 by compressing it to become a liquid and then injecting it into porous rocks deep underground.

He says the next challenge is for SeaCURE to scale up and “to operate for longer to prove it can capture millions of tons of CO2 each year.”

But he believes there is huge potential in recapturing carbon from ocean water. “Total carbon in seawater is about 50 times that in the atmosphere, and carbon can be resident in seawater for tens of thousands of years, causing acidification which damages the plankton and coral reef ecosystems. Removing carbon from the ocean is a giant task, but essential if the consequences of climate change are to be controlled,” he says.

NASA scientists are in a state of anxious limbo after the Trump administration proposed a budget that would eliminate one of the United States’ top climate labs – the NASA Goddard Institute for Space Studies, or GISS – as a standalone entity.

In its place, it would move some of the lab’s functions into a broader environmental modeling effort across the agency.

Career specialists are now working remotely, awaiting details and even more unsure about their future at the lab after they were kicked out of their longtime home in New York City last week. Closing the lab for good could jeopardize its value and the country’s leadership role in global climate science, sources say.

“It’s an absolute sh*tshow,” one GISS scientist said under condition of anonymity because they were not authorized to speak to the media. “Morale at GISS has never been lower, and it feels for all of us that we are being abandoned by NASA leadership.”

“We are supposedly going to be integrated into this new virtual NASA modeling institute, but (we have) no idea what that will actually look like,” they said.

NASA is defending its budget proposal, with a nod toward the lab’s future.
“NASA’s GISS has a significant place in the history of space science and its work is critical for the Earth Science Division, particularly as the division looks to the future of its modeling work and capabilities,” NASA spokesperson Cheryl Warner said in a statement.

“Fundamental contributions in research and applications from GISS directly impact daily life by showing the Earth system connections that impact the air we breathe, our health, the food we grow, and the cities we live in,” Warner said.

GISS has a storied history in climate science on the global scale.

James Hansen, a former director, first called national attention to human-caused global warming at a Senate hearing during the hot summer of 1988. The lab, founded in 1961, is still known worldwide for its computer modeling of the planet that enable scientists to make projections for how climate change may affect global temperatures, precipitation, extreme weather events and other variables.

Lido Finance: Leading Liquid Staking Protocol
lido finance
Lido Finance is a decentralized platform that enables users to stake their cryptocurrencies and earn staking rewards while maintaining liquidity through tokenized assets. It is one of the most popular liquid staking solutions in the DeFi ecosystem, supporting multiple blockchains including Ethereum, Solana, and more.

Lido Overview
Lido allows users to stake their assets without locking them up, providing flexibility and liquidity. When users stake their tokens via Lido, they receive a corresponding staked token (e.g., stETH for Ethereum), which can be used in other DeFi protocols, traded, or held for rewards.

Lido Fi
Lido Fi refers to the broader ecosystem of decentralized finance activities built around Lido’s staking tokens. It includes yield farming, liquidity pools, and integrations with various DeFi platforms, enabling users to maximize their crypto assets' utility.

Lido Staking
Lido staking involves depositing supported cryptocurrencies (like ETH, SOL, or others) into the Lido protocol. In return, users receive staked tokens that accrue staking rewards over time. This process is designed to be user-friendly, secure, and accessible to both individual and institutional investors.

Lido Finance ETH Staking
Lido Finance ETH staking is one of its flagship features, allowing users to stake ETH without needing to run a validator node. By staking ETH through Lido, users receive stETH, which represents their staked ETH plus accrued rewards, and can be used across DeFi applications.

Lido Finance Crypto
Lido finance crypto encompasses the native tokens (like stETH for Ethereum, stSOL for Solana, etc.), governance tokens, and other assets within the Lido ecosystem. These tokens facilitate staking, liquidity provision, and governance participation.
