Can Plankton Ferry Carbon to the Bottom of the Ocean?

Britain’s Natural Environment Research Council begins three teeny experiments.

Scientists at England’s University of Exeter believe that masses of drifting crustaceans “may help to store enormous amounts of carbon in the ocean,” at once sucking CO2 from the atmosphere and slowing climate change, the BBC reports. Britain’s Natural Environment Research Council has funded three projects to investigate the idea that the small, H.R. Giger-looking creatures, known as copepods or zooplankton, can absorb significant amounts of carbon.

“Don’t be fooled by their size,” said University of Exeter professor Daniel Mayor. “These tiny but mighty life forms play a crucial role in regulating Earth’s climate by moving carbon out of the atmosphere and shunting it down into the deep ocean where it says for hundreds of years or more.” Dr Adrian Martin, of England’s National Oceanography Center, added, “The need to understand how the ocean stores carbon has never been stronger and we know that marine life plays an important role.”

The forthcoming research recalls the work of Running Tide, a Maine start-up that hopes to use kelp to similar ends. As Heatmap’s Robinson Meyer wrote in The Atlantic last year, kelp “absorbs a huge amount of carbon through photosynthesis. [It] could then be harvested, disposed of, or allowed to naturally drift to the bottom of the ocean.” Along with an array of other possible techniques, it seems that the ocean — and the living things within it — could play a key role in the fight against climate change.

Koloma Strikes New Hydrogen Exploration Deal in the Philippines

The deal, shared exclusively with Heatmap, is the startup’s third in the oil-importing country.

Hydrogen fuel comes in myriad forms. There’s green hydrogen, which is extracted from water molecules using zero-carbon electricity. There’s blue hydrogen, derived from methane and scrubbed clean by carbon capture. And then there’s white hydrogen. Otherwise known as natural or geologic hydrogen, this type of hydrogen comes directly from naturally occurring deposits in the earth, can accumulate in considerable quantities and concentrations, and is highly energy-efficient to extract compared to manufacturing pathways such as electrolyzers and steam methane reforming.

It’s a seductive promise, but finding deposits with enough hydrogen to make the economics of exploration work is difficult. That’s where Koloma comes in. The startup uses a bespoke subsurface data set, which its founders developed over 20-plus years, to flag the areas most likely to hold sufficient hydrogen, after which they can extract it for power and derivative fuels.

Data Centers Will Use Enough Electricity to Power Every U.S. Household by 2035

The latest forecast from BloombergNEF raises its estimate for AI electricity demand by 83%.

Energy analysts at BloombergNEF predicted last year that U.S. data center electricity demand would reach 106 gigawatts within the next decade. In its latest outlook, released Tuesday, the group increased its forecast by 83%, to 194 gigawatts — enough to light up 150 million homes, or roughly every single household in the country today.

Even that may be a conservative estimate. If data center developers were to max out the total number of the high-powered chips used to train and operate AI models forecast to be delivered by 2035, electricity demand would reach 229 gigawatts.

Microsoft Sustainability Chief Hounded by Protestors at Seattle Climate Week

Protestors interrupted one of the final sessions of PNW Climate Week — a conference that brings together climate leaders across Washington, Oregon, and British Columbia — objecting to Microsoft’s rising carbon emissions from data centers and partnerships with oil and gas companies. The company’s Chief Sustainability Officer Melanie Nakagawa was having a one on one conversation with GeekWire climate reporter Lisa Stiffler at Seattle’s City Hall when protestors carrying signs reading “Microsoft’s AI pollutes” and other slogans began shouting from the audience.

I was there, having just moderated the prior panel on how to finance Washington’s clean energy ambitions. Early on there were some rumblings in the crowd from up front. “Climate leaders don’t build gas pipelines in Moses Lake,” was the first objection I heard clearly. It came shortly after Nakagawa kicked off the conversation by highlighting Microsoft’s partnership with sustainable aviation fuel startup Twelve, which recently opened its first commercial-scale SAF plant in Moses Lake, Washington. The tech giant has supported the project through a strategic investment from its Climate Innovation Fund, as well as an offtake agreement for the fuel that will help offset its emissions from employee travel.
