The debate around the effectiveness of carbon capture (you can register now for our CCUS session on Wednesday at 10.45 - Editor) has led to polarising views. Although the first implementations began 50 years ago, serious efforts to capture large volumes cost-effectively are in their infancy and unproven at scale. Is it, given time and support, a solution to excess emissions worldwide? Or is it a distraction that will allow fossils to be used yet … [Read more...]
Engineered soil microbe can convert CO2 20 times faster than natural photosynthesis
New research led by the U.S. Department of Energyâs 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, itâs very early days but could open a door to artificially … [Read more...]
Biologically produced Ethylene for plastics can become a carbon capture leader
Ethylene is a key component of the worldâs vast appetite for plastics. Itâs 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 OâNeil at NREL describes new research that makes ethylene in a âone-stepâ process fuelled … [Read more...]
Worldâs biggest Carbon Capture project: Shute Creekâs âsell or ventâ business model isnât working
ExxonMobilâs Shute Creek CCUS facility is the worldâs 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...]
Converting captured CO2 directly into fuels could get simpler, cheaper
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...]
Using captured Methane to make all the worldâs fishmeal: a profitable revenue stream?
If the cost of capturing methane (or CO2, or anything) can be folded into the cost of making something that can be sold at a profit, methane capture will take off. Rob Jordan at the Stanford Woods Institute for the Environment explains how research there shows captured methane can be turned into fishmeal at the same price as commercial fishmeal. In some cases it can be done much more cheaply. Commercial fishmeal, used to feed farmed fish, is … [Read more...]
Will this be the decade of Carbon Capture or another false start?
Ten years ago there was a major drive to get carbon capture off the ground. But only 30% of the earmarked $8.5bn worldwide was ever spent. Spending timescales were too short, deadlines were missed, projects were too focussed and too complex, and long-term liability was poorly understood and managed. This time it can be different, says Samantha McCulloch at the IEA who compares that faltering history with the plans now being put in place. New … [Read more...]
Renewed interest in Carbon Capture strategies for net-zero: targets, obstacles, costs, priorities
Martina Lyons at IRENA picks out the highlights of their new report âReaching Zero with Renewables: Capturing Carbonâ. Carbon capture is going to be expensive, so should be focussed on hard-to-abate industrial sectors, as well as bioenergy plants. Lyons breaks down the target carbon capture volumes, costs and the investments required, as well as looking at the consequences of different strategies and carbon prices. Scaling up this technology, … [Read more...]
COP26: a strategy for tackling âimported deforestationâ
Palm oil, beef, cocoa, coffee, soy, and other agricultural products are responsible for deforestation in the producing countries. Of the 10m hectares of tropical forest lost each year, two-thirds can be unambiguously attributed to agricultural expansion and international trade is responsible for about half of this. The EC is due in December to unveil a legislative proposal to address the issue. Alain Karsenty and Nicolas Picard, writing for IFRI, … [Read more...]
How much Carbon Capture will Germany need? Both nature-based and technological
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?
If you think CO2 removal isnât 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...]
Only Carbon Removal can make Germanyâs new climate goal a reality
Germany canât hit its emissions targets without significant carbon dioxide removal (CRD), explain Simon Göss and Hendrik Schuldt at cr.hub. Clean energy and energy efficiency wonât do it alone. Policymakers have grasped that hard-to-abate sectors (industry, agriculture, buildings, transport) will struggle to deliver the reductions needed. Meanwhile, the climate disasters (floods, wildfires, etc.) that have cost lives this year are piling on … [Read more...]
Comparing four Carbon Removal scenarios (IPCC, IEA, McKinsey, NGFS) and policy implications
Most net-zero scenarios include carbon removal as a major component. Simon Göss and Hendrik Schuldt at cr.hub review five major scenarios from the IPCC, IEA, ETC, McKinsey, and the Network for Greening the Financial System (NGFS). They start by making the very important distinction between carbon capture and negative emissions: capturing carbon from, say, a gas plant does not deliver negative emissions, it just prevents new emissions. This … [Read more...]
What if Carbon Capture fails? Modelling the consequences and solutions
Most policy scenarios being used by governments include carbon capture as a vital tool to reduce emissions. Though itâs far from proven at scale, models assume that between 2030 and 2050 carbon dioxide removal (CDR) will get its act together and deliver on its part in the net-zero puzzle. Assuming that will happen, burning fossil fuels can continue for longer. But Neil Grant and Ajay Gambhir at Imperial College London, writing for Carbon Brief, … [Read more...]
Europeâs Carbon Capture pipeline: 40+ projects. But whereâs the policy support and market creation?
13 different European countries have announced more than 40 carbon capture projects. Most are yet to become operational, but the commitment from the private sector â ranging from new players to established energy and industry majors â is clear. Now is the time for governments to create for CCUS the kind of policies that accelerated the growth of wind and solar, says Lee Beck at the Clean Air Task Force. Norway and the Netherlands are taking those … [Read more...]
