PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Though it is a greenhouse gas and requires careful supply chain management, methane has many applications, ranging from household use to industrial processes, said co-author and PNNL chemist Jotheeswari Kothandaraman. 2021), “Integrated Capture and Conversion of CO2 to Methane using a Water-lean, Post-Combustion CO2 Capture Solvent.”

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). In brief, the Fe–Mn–K catalyst shows a CO 2 conversion of 38.2%

T&E study finds plug-in hybrids show higher CO2 emissions than claimed

Green Car Congress

T&E has commissioned Emissions Analytics to test three of the most popular PHEVs sold in 2019: a BMW X5 (longest EV range PHEV available), a Volvo XC60 and the Mitsubishi Outlander. Selling plug-in hybrids makes it easier for carmakers to meet their EU car CO2 standards as PHEVs are currently given additional credits.

New Mercedes-Benz S-Class PHEV produces 14.1-36.2% lower CO2 emissions that predecessor

Green Car Congress

It offers tTwice the electric range at 100 kilometers, 110 rather than 90 kW of electric power and a level luggage compartment with through-loading facility. Alongside the CO2 improvement, the S 580 e also has advantages over its predecessor with respect to its eutrophication (EP) and summer smog (POCP) potential. kWh/100 km.

Audi and Krajete developing direct air capture technologies for CO2

Green Car Congress

The recovered CO 2 is then available in a highly concentrated form as a raw material for permanent storage or for a wide range of industrial applications. This made it possible to reduce significantly the cost of sequestration, which is already down to the low three-digits range in euros per ton of CO 2.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

The technology can also be scaled up to the megaton-per-year range and thus harbors great potential from the future. The direct air capture technology from Climeworks boasts two major advantages: Lifecycle analyses show that 90% of the CO 2 filtered out of the air is effectively and permanently stored underground.
