Bloomberg Green: Lawmakers Need to Do Whatever It Takes to Price Carbon

„Washington is once again talking about pricing carbon. The Clean Electricity Payment Program might be dead, but a carbon tax could still be on the table. Or it might not, or perhaps be replaced by expanded loan guarantees for clean energy, or by clean energy tax credits. Whichever form it might take, the politics will be tough. They always are, until they suddenly aren’t.“

Podcast: Carbon Removal Newsroom: Geoengineering vs. carbon removal, and California’s Cement Decarbonization legislation

„This week on Carbon Removal Newsroom[gt], we’re back with a policy-focused episode with panelists Dr. Holly Jean Buck of the University at Buffalo Chris Barnard of the American Conservation Coalition and host Radhika Moolgavkar of Nori. First up, we’re discussing an essay from Harvard professor David Keith in the New York Times titled, “What’s the Least Bad Way to Cool the Planet?” Keith compares Carbon Dioxide Removal (CDR) and geoengineering, pointing out that the two approaches operate on different timescales— CDR will take decades to build up, and longer still to have a significant impact due to the amount of CO2 in the atmosphere. Solar Radiation Management, a type of geoengineering, could be done with today’s technology and theoretically has an immediate cooling effect. There is a lot we don’t know but his ‘hunch’ is that geoengineering would work more quickly, be cheaper, and benefit the world’s hotter regions more immediately. He calls for governments to fund more research into the topic so the two techniques can be more accurately compared. We debate David Keith’s main points and Holly Buck describes the socio-technical systems that might be necessary to deploy geoengineering and larger-scale CDR most effectively. Next, we’re looking at the Cement Decarbonization legislation passed in California that mandates the state’s cement industry to become net-zero by 2045. According to the Climateworks Foundation’s Rebecca Dell, this is the first time any US state has required an industry to eliminate its net greenhouse gas emissions. Cement production is the second-largest emitter of any industry in California, after only oil and gas production, and it also contributes to significant local air pollution. While the greenhouse gas mitigation from this move is notable, this law also has the potential to provide needed policy support to the carbon removal and carbon utilization industries. We discuss the types of incentives that might be most successful in moving the needle on hard to abate emissions, then end the episode with a good news story of the week from Chris— Japan is restarting several aging nuclear reactors in an attempt to meet its carbon emissions goals.“

Mother Jones: Is Sucking Carbon Out of the Air the Solution to Our Climate Crisis?

In British Columbia, there’s a little valley where the Squamish River snakes down past the cliffs of the Malamute, a popular hiking spot. The hills in all directions are, like much of BC, thickly forested with firs. And nestled in that valley is a newfangled industrial plant that aims to replicate what those millions of trees do: suck carbon dioxide out of the air. The plant was built by Carbon Engineering, a pioneer in the technology known as direct air capture (DAC). In a long, squat building, a huge ceiling fan draws air inside, where it reacts with a liquid chemical that grabs hold of CO2 molecules.This “sorbent” flows into a nearby machine that transforms the gas, which is then stored in pressurized tanks. The goal is to help rid the atmosphere of its most ubiquitous climate change culprit. The Squamish plant will process up to 1,000 metric tons of CO2 annually. That’s a minuscule drop in the bucket of the planet’s annual emissions, an estimated 33 billion metric tons last year, but this plant is only a pilot facility.“

Energy.Gov: DOE Invests $45 Million to Decarbonize the Natural Gas Power and Industrial Sectors Using Carbon Capture and Storage

„The U.S. Department of Energy (DOE) today announced $45 million in funding for 12 projects to advance point-source carbon capture and storage technologies that can capture at least 95% of carbon dioxide (CO2) emissions generated from natural gas power and industrial facilities that produce commodities like cement and steel. These research and development, front-end engineering design and engineering-scale projects are a part of DOE’s efforts to deploy a portfolio of innovative solutions to help achieve the Biden-Harris Administration’s goals of net-zero carbon emissions by 2050 and a 100% clean electricity sector by 2035.“

The Hill: Geoengineering: We should not play dice with the planet

„The fate of the Biden administration’s agenda on climate remains uncertain, captive to today’s toxic atmosphere in Washington, DC. But the headlines of 2021 leave little in the way of ambiguity — the era of dangerous climate change is already upon us, in the form of wildfires, hurricanes, droughts and flooding that have upended lives across America. A recent UN report on climate is clear these impacts will worsen in the coming two decades if we fail to halt the continued accumulation of greenhouse gases in the atmosphere.To avert disaster, we must chart a different climate course, beginning this year, to achieve steep emissions reductions this decade. Meeting this moment demands an all hands-on-deck approach. And no stone should be left unturned in our quest for meaningful options for decarbonizing our economy.“
