New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

V for neutral NaAlCl 4 ) contributed by the acidic chloroaluminate cathode reaction, unlocking an additional specific energy of ∼119 Wh kg −1 by utilizing the conversion of NaAlCl 4 to NaAl 2 Cl 7 , which adds to the neutral melt reaction between NaAlCl 4 /Al and Na (∼493 Wh kg −1 theoretical). mAh cm −2 , a discharge duration of 28.2

S&P Global: More than 75% of oil and gas production in US Gulf of Mexico has lower than average greenhouse gas intensity

Green Car Congress

Conversely, assets on the upper bound of carbon intensity—responsible for just 10% of total production—generated 35% of the basin’s total GHG emissions. For comparison, the GHG intensity range for 99% total 2021 production across the North Sea study area extends to c. The full range, including outliers, extends up to c.

Stanford researchers develop copper-based catalyst that produces ethanol from CO at room temperature; potential for closed-loop CO2-to-fuel process

Green Car Congress

The material’s selectivity for oxygenates, with ethanol as the major product, demonstrates the feasibility of a two-step conversion of CO 2 to liquid fuel that could be powered by renewable electricity, the team suggests in their paper published in the journal Nature. Carbon Capture and Conversion (CCC) Catalysts Ethanol'

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories. The lowest WTW energy demand and GHG emissions were achieved using electricity from waste incineration, biogas CHP, hydropower, wind power, and photovoltaic power.

Ford Europe leading project investigating DME and OME1 as low carbon, near zero particulate fuels; power-to-liquids pathways using CO2

Green Car Congress

The comparison to the electric vehicle is based on estimates which factor in the CO 2 emissions resulting from fuel production, with the DME-powered vehicle figure calculated from the use of renewable energy to generate the DME fuel, and the electric vehicle figure calculated from electricity generated from renewable resources.

Aachen team develops framework for model-based formulation of biofuel blends with tailored properties

Green Car Congress

The researchers envision that the model-based approach can (i) guide fundamental experimental investigations of the combustion behavior of blended biofuels toward the most favorable mixtures and (ii) identify promising conversion pathways for further elaboration by means of reaction engineering and conceptual process design.

Review finds encouraging progress in electrochemical reduction of CO2 to organic compounds; substantial advances in catalysts, electrolytes and reactors still required

Green Car Congress

However, the two conclude in their review, substantial advances in catalyst, electrolyte, and reactor design are needed to enable CO 2 utilization via electrochemical conversion a technology that can help address climate change and shift society to renewable energy sources. Current research efforts in the electrochemical conversion of CO 2.
