FAQs about Drivers and implications of alternative routes to fuels ... - Nature Coupon?

How does a low-carbon energy pathway affect natural gas consumption?

More carbon management is required in the low electricity pathway, with increased DAC use driving higher natural gas consumption compared to the high electricity pathway. Hydrogen can play an important role as a low-carbon energy carrier. Its absence in the low hydrogen pathway results in higher transportation and industrial emissions. ...

Do hydrocarbon fuels decline during net-zero emissions?

Although hydrocarbon fuels typically decline in such scenarios, significant volumes remain in many scenarios even at the time of net-zero emissions. While scenarios rely on different approaches for decarbonizing remaining fuels, the underlying drivers for these differences are unclear. ...

Do decarbonization pathways reduce natural gas use?

Overall, reductions in natural gas use across all decarbonization pathways are a consequence of the increased electrification of end-use technologies in all sectors. However, despite substantial reductions, all decarbonization pathways retain some level of natural gas use. ...

Is carbon management required in all illustrative pathways?

Carbon management is required in all illustrative pathways, but there is heterogeneity in the technologies chosen for this purpose. For example, the low hydrogen and high electricity pathways rely on carbon management from several technologies. ...

What is the exogenous final demand for natural gas vs liquid fuels?

It is also worth noting that the assumed exogenous final demand for natural gas is considerably lower than the final demand for liquid fuels (30 EJ for natural gas versus 91 EJ for liquid fuels), although there is significant variability across IPCC 1.5 °C scenarios in 2050 (see Supplementary Table 2). ...

What technologies are used in the near cost-optimal decarbonization pathway?

In the near cost-optimal decarbonization pathways examined in this paper, there is a notable trend toward widespread adoption of specific technologies such as solar and wind power, grid-connected energy storage, and electrification across various sectors, including industry, transportation, residential, and commercial sectors. ...
