“Early progress from the first focused research organizations has strengthened Marblestone’s conviction that they’re filling a gap.

[C]Worthy is the FRO building tools to ensure safe, ocean-based carbon dioxide removal. It recently released an interactive map of alkaline activity to improve our understanding of one method for sequestering carbon known as ocean alkalinity enhancement.”

‘"Large volume for contact is one of the reasons why the ocean presents scalable approaches to carbon dioxide removal," says Matthew Long, an Adjunct Scientist at the Woods Hole Oceanographic Institution (WHOI) in the U.S. Long is the Co-founder and CEO of [C]Worthy, a non-profit that researches marine CDR solutions.’

“Even if these solutions do work long term, most companies are operating on too small of a scale to influence the climate. Expanding to meet current climate goals will take massive amounts of resources, energy and money.”

[C]Worthy cofounder and CTO Alicia Karspeck is interviewed by Yale Climate Connections: “It’s actually a natural process that happens already on very long geologic timescales, and it’s a matter of just accelerating that natural process.”

“This is pretty hard, right?,” University of Hawaii Oceanography Professor David Ho tells Sentient. “If we’re talking about carbon dioxide removal, basically, you’re talking about the largest thing that humanity has ever done.”

‘[Karspeck] said building trust is fundamental to effective markets, “even more the case when you don’t have the government actually creating or mandating that.”’

“It may be surprising that it should take so long to quantify this process, but partly it’s because this is a hard problem to examine,” Ho said.

‘“It has to go from something that most people have never heard of to the largest industry the world has ever seen, in a really short time,” said David Ho, an ocean scientist at the University of Hawaii at Manoa.’

“I think carbon removal is a tool for the future,” David Ho, a climate scientist and cofounder of the nonprofit [C]Worthy, told us. ​“Now is the time we figure out what works and what doesn’t work. It’s almost an obligation to future generations to give them tools to remove the CO₂ that we’re leaving them and let them decide whether to deploy these tools or not — it’s not for today.”

“It doesn’t make sense to use CCS to prolong our use of fossil fuels, especially to produce electricity,” said David Ho, professor at University of Hawaii and senior researcher at Columbia University. “The argument in favor of enhanced oil recovery is often that if they weren’t using this captured CO2, they’d be using some other CO2, but I don’t think you can call anything where you’re getting more oil out of the ground to burn a climate solution.”

“People hear chemistry and they don’t like that,” says David Ho, a geochemist and professor of oceanography at the University of Hawaiʻi at Mānoa.

“The verification step has to be non-profit, and it has to be separate from your money-making scheme,” says Ho, who co-founded [C]Worthy, a nonprofit that makes open-source software to quantify the efficacy and side effects of marine carbon removal. “As ocean biogeochemists, if we have the inclination and we have the skills, then it behooves us to work on it.”

“These projects are also challenging to do in an academic setting because they require a larger group of people than you have in a single academic lab…So, what they proposed was to create non-profit science startups.”

‘CDR can be thought of like “a time machine,” David Ho, an oceanographer at the University of Hawaii at Manoa, wrote last year in Nature. Stripping some of the CO2 out of the atmosphere would be like returning to an earlier time with lower concentrations.

"As the world hurtles toward dangerously warmer temperatures, international experts advise that carbon removal will be essential to avoiding the worst climate outcomes.”

“It doesn’t make sense to use CCS to prolong our use of fossil fuels, especially to produce electricity,” said David Ho, professor at University of Hawaii and senior researcher at Columbia University. “The argument in favor of enhanced oil recovery is often that if they weren’t using this captured CO2, they’d be using some other CO2, but I don’t think you can call anything where you’re getting more oil out of the ground to burn a climate solution.”

"Matt Long, a scientist at the National Center for Atmospheric Research and director of [C]Worthy, a nonprofit aiming to help build tools to measure and verify ocean carbon removal, is working on a project that received about $3.9 million in ARPA-E’s announcement today.”

"'This project represents the first time an alkalinity release will be conducted along with the dual tracer technique and allows us the opportunity to determine the movement of CO2 between the ocean and atmosphere and track the evolution of an ocean alkalinity enhancement…”

‘The problem is, ocean uptake is relatively slow, compared to our rate of emission,' Long told Salon in a phone interview.
