$50 million prize funded by Musk foundation goes to Indian carbon-capture company

An Indian institution that spreads crushed stone connected farmers' fields to assistance gully climate-warming c dioxide from the ambiance has been awarded a $50 cardinal expansive prize successful a planetary contention funded by Elon Musk's foundation.

Mati Carbon was among much than 1,300 teams from 88 countries that participated successful the four-year XPRIZE Carbon Removal competition, launched successful 2021 to promote deployment of carbon-removal technologies. Many scientists judge removing c is important successful the combat against planetary warming, caused by the burning of fossil fuels similar gasoline, ember and oil, which merchandise c dioxide.

“It's important that we not beforehand c dioxide removal arsenic a replacement for emissions reduction,” said Michael Leitch, the method pb for the competition. “But the contention is truly connected some to dramatically trim our existing emissions (and) besides ... deploy c dioxide removal solutions astatine very, precise ample scales globally.”

The prize is being awarded astatine a clip erstwhile Musk and his Department of Government Efficiency are making steep cuts to national backing and unit astatine the National Oceanic and Atmospheric Administration, the National Weather Service and different science-based agencies that transportation retired important clime research. The Trump medication has besides moved to rotation backmost myriad biology regulations, including immoderate that modulate c emissions.

While the Musk Foundation sponsored XPRIZE Carbon Removal, which distributed a full of $100 million, it is not formally affiliated with the California-based organization, XPRIZE officials said.

XPRIZE runs different contests to effort to lick societal challenges. Executive manager Nikki Batchelor said the enactment is considering much climate-related competitions addressing specified issues arsenic removal of the potent greenhouse state methane, reforestation and clime adaptation and resilience.

Mati Carbon CEO Shantanu Agarwal believes his company's comparatively low-cost attack “has a imaginable to truly lick immoderate planetary standard problems” portion helping tiny farmers who often carnivore the brunt of clime change, arsenic utmost upwind events similar drought and floods destruct crops.

The method, called enhanced stone weathering, is reasonably straightforward, said Jake Jordan, the company's main subject officer: When it rains, h2o and c dioxide premix successful the atmosphere, forming carbonic acid, which falls connected stone and yet breaks it down into tiny bits of silica. The carbonic acerb is converted to a mineral called bicarbonate, which cannot re-gas to the ambiance and yet is washed to the ocean, wherever it is stored for astir 10,000 years.

Mati Carbon spreads already-crushed basalt stone — plentiful successful galore parts of the satellite — connected the fields “to velocity up thing that happens anyway,” Jordan said. The crushed stone besides releases nutrients that assistance regenerate soils and summation productivity.

Smaller prizes were awarded successful the competition’s last twelvemonth to respective different teams that besides successfully removed 1,000 tons of c dioxide, a threshold that demonstrates an quality to standard up to region gigatons successful the coming decades.

That included $15 cardinal to runner-up NetZero, which turns harvest residues specified arsenic java husks into biochar, charcoal-like particles that tin beryllium utilized connected fields to assistance store c successful soils portion besides improving nutrient and h2o retention.

Other projects progressive storing integrated discarded heavy underground, enhancing oceans' quality to store c and removing c straight from the air.

Scientists person been exploring the gamut of alleged geoengineering solutions to clime change, from drying the upper atmosphere to pumping minerals into the ocean to sorb carbon.

Rick Spinrad, erstwhile head astatine NOAA, called the finalists' solutions “scientifically bonzer concepts” and said the champion attack to reducing c astir apt volition beryllium a operation of technologies.

Leitch, from XPRIZE, said immoderate solutions that did not triumph — including nonstop aerial and nonstop water seizure of c dioxide — mightiness person an vantage erstwhile deployed connected a ample scale.

“It takes a batch of clip and wealth to build, truthful I deliberation clip volition tell,” Leitch said.
