Concrete supercapacitor: works like a battery, much cheaper, easy to make

September 27, 2023 by David Chandler

Capacitors work like batteries. They store and discharge electricity. David Chandler at MIT explains how researchers there have designed a supercapacitor from concrete and carbon black, two cheap and common materials. The beauty of the idea is that they can be incorporated into building foundations, thus installing a battery virtually for free. A concrete capacitor cube 3.5m wide can store 10kwh, enough for a household. Similarly, concrete … [Read more...]

“Book and Claim”: how end consumers can pay distant producers for low carbon products

July 12, 2023 by Thomas Koch Blank, Laura Hutchinson, Oscar Hernandez, Esther Sicong Li and Alexandra Wall

In long logistical chains (found in steel, concrete, aviation, shipping and others) end consumers that want to pay a premium to cut their emissions (for example to comply with corporate decarbonisation promises) often have no way to pay the first link in that chain to go low-carbon. “Book and Claim” creates a market to do that. Consumers buy certificates, and producers get the money to fulfil the commitment. And a working system will bring to … [Read more...]

Adding ordinary baking soda to concrete production can cut 15% of its CO2 emissions

April 12, 2023 by David Chandler

Concrete production makes up 8% of global CO2 emissions. Half comes from the fossil energy used to make it (which, hopefully, can transition to clean power), and the other half comes from the CO2 that escapes during the chemical transformation. David Chandler at MIT describes research there that shows how simply adding sodium bicarbonate (yes, the baking soda you put in your cookies) during the early stages of production can remove, by … [Read more...]

Embodied Carbon Emissions: understanding the different methodologies being used around the world

February 28, 2023 by Max Gruenig

The measurement of the embodied carbon emissions of goods tells us what greenhouse gas emissions are generated during the production and transportation of those goods. This achieves two main things. Firstly, it allows producers to understand where their emissions are coming from, and so reduce them. Secondly, it opens the door to putting a price on those emissions, thus incentivising producers to reduce them. But, as Max Gruenig at E3G explains, … [Read more...]

Concrete: 8% of global emissions and rising. Which innovations can achieve net zero by 2050?

January 24, 2023 by Ben Skinner and Radhika Lalit

Concrete manufacture is responsible for 8% of global carbon emissions, with the ingredient “clinker” accounting for most of it. Global demand for cement (which hardens into concrete) is expected to increase 48% from 4.2bn to 6.2bn tons by 2050, mainly driven by developing nations. China used more concrete between 2011 and 2013 than the United States did in the entire 20th century. Ben Skinner and Radhika Lalit at RMI look at the materials and … [Read more...]

10 Carbon Capture methods compared: costs, scalability, permanence, cleanness

November 11, 2019 by Ella Adlen and Cameron Hepburn

We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the cost per tonne. In their list the authors, Ella Adlen and Cameron Hepburn at the University of Oxford, cover the industrial (e.g. CO2-EOR, synfuels) to the biological (e.g. forestry, soil carbon sequestration). They say there are six that can be … [Read more...]
