Engineering and Technology: On-board CO2-capture method could make long range ships carbon negative

„Researchers in the US have offered a practical way to make ships carbon neutral with CO2-capturing solid oxide fuel cells on-board.The method, proposed by a team at Northwestern University, suggests that after ‚burning‘ traditional carbon-based fuels, the fuel cell generates concentrated CO2 that can be stored on-board the ship. From there, the CO2 can either be sequestered or recycled into renewable hydrocarbon fuel.“

CNBC: Climate experts are worried about the toughest carbon emissions for companies to capture

„Scope 3 carbon emissions, or those not part of operations or under direct control, represent the majority of the carbon footprint for most companies, in some cases as high as 85% to 95%. As companies lay out ambitious carbon reduction targets and net-zero pledges for the decades ahead, slow progress on tracking Scope 3 emissions has climate experts worried.“

GreenBiz: U.S. infrastructure bill lays foundation for carbon management economy

„It’s not the law of the land yet, but one of the most potentially impactful aspects of the bipartisan infrastructure bill for climate techies is the groundwork it lays for new economic opportunities based on capturing and sequestering carbon emissions. The support for the so-called carbon management economy takes many shapes within the bill, and is largely based on the SCALE Act reintroduced earlier this year by senators on both sides of the aisle. (SCALE stands for Storing CO2 and Lowering Emissions).“

Illuminem: Time to Rethink Nature-Based Solutions?

„It has been more than 30 years since the first carbon offset project used a nature-based solution (agroforestry and forestry conservation) to offset the emissions of a coal-fired power plant owned by the energy company AES. I developed the carbon quantification methodology for that offset project while at the World Resources Institute in Washington, DC. I subsequently authored some of the earliest studies looking at nature-based solutions (NBS) potentials for climate change mitigation, and worked extensively with the Intergovernmental Panel on Climate Change (IPCC) on the topic.[…] NBS references a large category of climate change mitigation options based on preserving, restoring, or expanding biological stores of terrestrial or oceanic carbon. Protecting tropical rainforests, rewilding temperate zones, restoring soil carbon on agricultural lands, and sinking seaweed into the ocean are all examples of NBS options.“

Podcast: Carbon Removal Newsroom: Carbon pricing bills, forest carbon offsets, & a progressive platform for carbon removal

„This week on Carbon Removal Newsroom, we’re discussing carbon’s value in various forms. We start by answering the question, ‘What is carbon pricing?’ and look at proposed bills in Congress that are attaching a price to carbon. We look at the value of forest carbon offsets in a world with unprecedented wildfires. We explore A Progressive Platform For Carbon Removal, then we close out the episode with a positive story of the week.Panelists Dr. Holly Jean Buck of the University at Buffalo and Chris Barnard of the American Conservation Coalition join host Radhika Moolgavkar of Nori for this episode.“
