Terri reporting: Electrofuel developed from green hydrogen and carbon dioxide … Using Finnish technology, we have succeeded in producing E-diesel, or electrofuel, from green hydrogen and carbon dioxide on a pre-commercial scale. The fuel can be used to replace fossil diesel in sectors that are difficult to electrify, such as heavy road transport and shipping. It can also be used in machinery. Our next step is to obtain information on the usability of the fuel in a field test," says VTT Research Professor Juha Lehtonen.


Two new studies inform outlook on scaling of carbon removal … In one of their recent papers published October 30, 2023, in Communications Earth & Environment, Nemet and his research team debut the Historical Adoption of TeCHnology (HATCH) dataset—an innovative project that tracks and analyzes a variety of agricultural, industrial and consumer technologies adopted over the past century that can provide insight into the scale-up of new technologies such as carbon removal.


The study analyzed the emergence and growth of 148 technologies across 11 categories going back to the early 20th century. It then cross-referenced this data with model CDR scenarios established by the Intergovernmental Panel on Climate Change (IPCC), company announcements of CDR scale-up plans, and CDR targets in policy announcements.

While the paper found evidence that the required scale-up of carbon removal technologies fits within the historical range of previous efforts, company announcements and government targets implied there would be much faster growth than the historical record and IPCC CDR modeled scenarios.


"The scale-up rates needed for carbon removal to meet the 2- and 1.5-degree Celsius targets are within the range of historical experience, even if at the high end," says Nemet. "We can learn from that experience to facilitate getting carbon removal to climate-relevant scale over the next three decades."


In another paper published November 15, 2023, in Joule, Nemet and his research team find that 2 gigatons of carbon dioxide removal per year is currently taking place. Nearly all of that removal is accomplished by planting more trees and only 0.1% from novel CDR.


This is all despite modeling scenarios that show that we need to remove hundreds of gigatons of carbon dioxide from the atmosphere over the course of the century to meet the Paris Agreement and ensure the sustained well-being of our planet.

The study finds that virtually all scenarios that limit warming to 1.5 or 2 degrees Celsius require novel CDR. On average, scenarios increase novel CDR by a factor of 1,300 by mid-century.
