IEA: global CO2 emissions rebounded to their highest level in history in 2021; largely driven by China

Green Car Congress

The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions—notably the spikes in natural gas prices—which led to more coal being burned despite renewable power generation registering its largest growth to date. billion tonnes. billion tonnes.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

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. The process is constrained by the (low) cost of electricity. Johnson et al.

ICCT: incremental technology can cut vehicle CO2 by half and increase fuel economy >60% through 2030 with ~5% increase in price

Green Car Congress

These fuel economy levels are achieved based on a sustained 4%–6% annual reduction of fuel use per mile with incremental technology additions that do not compromise vehicle size or utility at an incremental cost of $800–$1,300 from 2025 to 2030. Previous costs of compliance have been greatly overestimated. Source: The ICCT.

Study for European Parliament assesses options for turning CO2 into methanol for use in transport

Green Car Congress

The need for bringing down the costs of captured CO 2 and stimulating its potential uses, among them methanol production. This has considerable implications for policy making, since the numerical evidence for comparing different fuels and car performance is not presently available, as the second interim report of this study has shown.

ICCT calculates consumer benefits of increased efficiency in 2025-2030 light-duty vehicles in the US

Green Car Congress

Those who finance their vehicles will see a net positive cash flow—again, specific to the additional cost of technology—starting immediately. Consumer benefits would be more than 3 times the costs of the standards. times the costs if fuel prices stay low for the next several decades. Fuel savings are 2.4

BNEF: net-zero road transport by 2050 still possible, but big push needed

Green Car Congress

Electric vehicles are a powerful tool in reducing global CO2 emissions from the transport sector. Yet, the rising cost of batteries will not derail near-term EV adoption. The report also found that vehicle-to-grid (V2G) technology can play a role in driving down power sector emissions and generating value for consumers.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

In the near-term pre-CCS era, with a low cost of carbon, the economical solution for power providers is to vent the CO 2 and pay the fees, passing on the costs to customers. Over time, however, as the CO 2 price increases, it eventually becomes more economical to either retrofit plants to capture and store most of.
