Starting in 2023, Daimler Buses will also equip its previously purely battery-electric Mercedes-Benz eCitaro city bus, which has been in series production since 2018, with a hydrogen-based fuel cell as a range extender in both solo and articulated models. The eCitaro Range Extender is still clearly designed for use as a city bus.
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%).

Researchers at the US Naval Research Laboratory (NRL) are investigating an optimized two-step process for the synthesis of liquid hydrocarbons in the jet fuel range from CO 2 and hydrogen. CO 2 is 140 times more concentrated in seawater than in air on a weight per volume basis (g/mL), the authors note.
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.”
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.
Other conclusions from the work were that tail pipe emissions in a number of specific applications such as refuse trucks were significantly better than the EURO 6 base vehicles, with the NO x emissions reduced by between 29-85% across the range of cycles tested.

Although N 2 and noble gases such as Ar are more abundant in ambient air, the conventional cathode voltage range of ?3 Lithium-air batteries, with a theoretical gravimetric energy density of ?3500
With consistent lightweight design, the use of steel increases the weight of the battery by only around one to one-and-a-half percent and is therefore negligible in terms of driving performance and range. Instead of multiple screw solutions, bonding and welding seams, IAV engineers have introduced new joining techniques.
The resulting CNT wool is of length suitable for weaving into carbon composites and textiles and is highly conductive; the calculated cost to produce the CNTs is approximately $660 per ton, compared to the current $100,000+ per ton price range of CNTs. A paper on the work is published in the journal Materials Today Energy. Johnson et al.
The researchers are experimenting with a range of different catalysts to improve both stability and efficiency. While this technology will be easier to scale up than the artificial leaf, the efficiencies still need to be improved before any commercial deployment can be considered.
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.
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.

The committee also proposed indicative targets for post-2020 CO 2 emissions in a range of 105 to 120 g/km (168 to 192 g/mile) from 2025. The draft also sets indicative targets for post-2020 CO 2 emissions in the range of 68-78 g/km (109-126 g/mile) from 2025. The vote was 53 to 4 with 1 abstention. Earlier post.).
The team found that, contrary to common belief, a PHEV with about 60 km (37 miles) of real-world range currently electrifies as many annual vehicles kilometers as a BEV, despite having a much smaller battery. Also shown are the annual electrified VKT by BEV and PHEV with typical ranges as shaded areas under the curve. Plötz et al.
The analysis covered 23 markets in Europe and found a direct correlation between diesel car registrations and average CO2 emissions. The total value of CO2 emissions was on a steady decline from 2007, but started to slowdown in 2016 as the fall reduced from -4.1 Last year, 60% of its registrations were within the hybrid range.

The new Golf Variant model now features three natural gas tanks—instead of just two as before—once again increasing the already long range of the CNG drives. extra-urban 3.0 / combined 3.6;
National governments should provide fiscal incentives only for those plug-in hybrid vehicle models that offer a high electric range and limit the power of the built-in combustion engine. —ICCT Director Dr. Peter Mock. Meanwhile, legal and financial barriers for installing home charging devices should be reduced.
It clearly shows that there are a range of potential routes to deliver significant carbon reductions, including both increased electrical mobility with battery vehicles and plug-in hybrids but also low carbon liquid and gaseous fuels. that are modelled in the “Best case 2020” scenarios.
By 2050, all regions have reduced new vehicle fuel consumption by 83% relative to 2010 yielding average new vehicle TTW emission targets in 2050 ranging from 24 g CO 2 /km in Latin America to 32 g CO 2 /km in North America. For the EU, the glide path is at the upper end of the discussed 2025 EU range of 68–78 g CO 2 /km.
CNG provides a range—based on standard fuel consumption—of around 400 km (249 miles), with gasoline providing another 900 km (559 miles) if necessary; the total range of 1,300 km (808 miles) is approximately on a par with an Audi TDI. The Audi A3 Sportback g-tron is fully bivalent—i.e.
The 132 kW B Class Electric Drive has a range of some 200 km (124 miles). This further enhances the efficiency of the drive system and enables even greater ranges. In the interests of optimizing the range, the top speed is electronically limited to 160 km/h (99 mph). kWh/100 km) produces 11.9 The B-class takes 7.9
