New U.S. study: damage per ton of CO2 costs $185, not the official $51

October 7, 2022 by Maximilian Auffhammer

Maximilian Auffhammer at the Energy Institute at Haas reviews a new paper that suggests CO2 causes over three times as much damage in dollar terms as the figure currently used by the US government, $51 per ton. The new study shows $185 per ton of CO2 as the Social Cost of Carbon (SCC). The updated model is superior to previous models, says Auffhammer. It’s also open source, so anyone can use it, criticise it, and tweak the numbers to get … [Read more...]

Electrochemical CO2 removal: efficient, cheaper, first industrial client

October 5, 2022 by Leda Zimmerman

Leda Zimmerman at MIT describes a method of removing CO2 electrochemically, now being taken forward by MIT spin-off company Verdox. Electrodes are coated with polyanthraquinone. When it is charged, CO2 sticks to it. When it’s time to store it away, the charge is reversed and the gas is expelled as a pure stream of CO2. The technology works in a wide range of CO2 concentrations, from the 20% or higher found in cement and steel industry exhaust … [Read more...]

Clean Turquoise Hydrogen: a pathway to commercial readiness

July 22, 2022 by Schalk Cloete

Whereas blue hydrogen from methane produces CO2, the by-product of turquoise hydrogen is pure carbon. The obvious advantage is you can make your hydrogen without the need for expensive new infrastructure to transport and store any CO2. Turquoise hydrogen is only at the start-up phase, so Schalk Cloete summarises his co-authored paper that looks at various scenarios to estimate the cost of producing the hydrogen (using molten salt pyrolysis) and, … [Read more...]

Engineered soil microbe can convert CO2 20 times faster than natural photosynthesis

June 8, 2022 by Glennda Chui

New research led by the U.S. Department of Energy’s SLAC National Accelerator Laboratory and the Max Planck Institute for Terrestrial Microbiology in Germany has shown how a bacterial enzyme found in the soil can be made to convert carbon dioxide into carbon compounds 20 times faster than plant enzymes do during natural photosynthesis. As Glennda Chui at Stanford University explains, it’s very early days but could open a door to artificially … [Read more...]

Biologically produced Ethylene for plastics can become a carbon capture leader

May 25, 2022 by Connor O'Neil

Ethylene is a key component of the world’s vast appetite for plastics. But it’s normally made using fossils as a feedstock, and is energy-intensive to produce. So the chemicals industry has long sought a way to biologically manufacture ethylene. It would be a double-win for clean energy: it would capture CO2 and displace the fossil-based feedstocks. Connor O’Neil at NREL describes new research that makes ethylene in a “one-step” process fuelled … [Read more...]

Aviation policy alert: non-CO2 emissions have up to four times the climate impact

April 14, 2022 by Carlos LĂłpez de la Osa

There’s little point designing CO2 policies without knowing what other factors are heating up the atmosphere. So it is with aviation. The non-CO2 emissions (aromatics, NOx, SO2, H2O, particulate matter, etc.) from jet engines have up to four times the effect of CO2. You can see it in the contrail cirrus streaks trailing behind aircraft. Carlos LĂłpez de la Osa at Transport & Environment summarises their recent summit that brought together … [Read more...]

World’s biggest Carbon Capture project: Shute Creek’s “sell or vent” business model isn’t working

April 11, 2022 by Bruce Robertson and Milad Mousavian

ExxonMobil’s Shute Creek CCUS facility is the world’s largest carbon capture project. But since its launch in the 1980s half of that CO2 has been vented into the atmosphere, with most of the rest sold for pumping it underground to push out more oil from depleted wells (called Enhanced Oil Recovery). Only 3% has been sequestered underground, explain Bruce Robertson and Milad Mousavian at IEEFA, following their study based on publicly available … [Read more...]

Could nano-scale filters for isolating CO2, Hydrogen and Biogas accelerate the energy transition?

April 6, 2022 by David Chandler

Nano-scale filters have been developed to separate out molecules like CO2 and hydrogen from gaseous streams. The research, led by MIT, could open a new door to raising the efficiency of carbon capture, isolating hydrogen for fuel use, and the purification of biogas fuel from waste. David Chandler at MIT explains how it would replace century-old methods of separating gaseous molecules that use energy-intensive and hard-to-electrify high … [Read more...]

Lifting 3.6bn people out of poverty would raise global emissions by 18%

March 1, 2022 by Ayesha Tandon

One criticism of the energy transition is that efforts made by the rich world will be negated by the rise in wealth and consumption in the developing world. A new study puts figures on that expected increase in emissions. Eradicating all “extreme poverty” – by raising hundreds of millions above the US$1.90 per day threshold – would drive up global carbon emissions by less than 1%. Lifting 3.6 billion people over the poverty line of US$5.50 per … [Read more...]

Converting captured CO2 directly into fuels could get simpler, cheaper

February 23, 2022 by David Chandler

Converting captured CO2 directly into fuels (or other products) at scale seems an effective way to mitigate emissions. But most of the conversion methods, including electrochemical, thermocatalytic, photothermal, or photochemical processes, have not proved very effective. David Chandler at MIT describes how researchers there have identified the main stumbling block and found a very simple solution. Basically, at the molecular level, the contact … [Read more...]

What’s your average lifetime CO2 footprint by year of birth, to achieve net-zero by 2050?

February 18, 2022 by Laura Cozzi, Olivia Chen and Hyeji Kim

To reach net zero by 2050, babies born today must have CO2 footprints ten times smaller over their lifetimes than their parents and grandparents. In rich countries it’ll be fifteen times, while in emerging economies like India and China it’ll be around four times smaller. Laura Cozzi, Olivia Chen and Hyeji Kim at the IEA summarise how they have calculated the average allowable lifetime CO2 footprint by year of birth. Taking the two extremes, the … [Read more...]

E-fuels for cars are expensive, and pollute the air as much as petrol

December 13, 2021 by Transport & Environment

MEPs and governments are currently deciding on an EC proposal for all new cars sold from 2035 to be 100% zero-emissions. Here, T&E present test results that show e-fuels should not be allowed to replace petrol. T&E are concerned that e-fuels are being promoted as a way to prolong the life of ICE vehicles. But their tests show that e-fuels produce just as much NOx, three times more carbon monoxide, and twice as much ammonia. Though e-fuels … [Read more...]

COP26 accepted the science like never before. It should make a difference

December 1, 2021 by Sonia Seneviratne, Maisa Rojas, Pep Canadell, Christophe Cassou, Piers Forster, Nana Klutse, June-Yi Lee and Joeri Rogelj

Leading scientists, writing for Carbon Brief, explain how COP26 gave far greater recognition to science than any of the previous COPs. The scientific evidence from the latest IPCC reports was explicitly acknowledged in the Glasgow Climate Pact. That is a significant advance, say the authors. Decision-making guided by science can focus quantitively on carbon budgets, temperatures, climate change, the causes, and therefore the emissions-reductions … [Read more...]

How much Carbon Capture will Germany need? Both nature-based and technological

October 29, 2021 by Simon Göss and Hendrik Schuldt

Yet more studies have been published that show Germany needs carbon removal to meet its emissions targets. Simon Göss and Hendrik Schuldt at cr.hub add two, from the German Energy Agency and the Ariadne report (funded by the German Ministry of Education and Research), to those that already exist to shine more light on a carbon capture pathway. The main observation is that nature-based solutions (LULUCF: land use, land use change and forestry) … [Read more...]

Methane Removal: an overlooked climate solution that could cut temperatures by 1°C?

October 13, 2021 by Rob Jordan

If you think CO2 removal isn’t getting enough attention, methane removal is getting virtually none. There are attempts to reduce methane emissions directly from fossil fuel production. But Rob Jordan at the Stanford Woods Institute for the Environment describes studies and models that conclude we should be looking at large and wide scale reduction and capture of methane. A 40% reduction in global methane emissions by 2050 could reduce peak … [Read more...]
