Abstract:

A major proposal to transition the global economy away from fossil fuels is to “electrify everything” allowing for low-carbon power production to replace fossil fuel oxidation. Here we conduct a techno-economic analysis of a diverse set of electrification technologies to determine the technical feasibility and economic cost of full-scale electrification. We find that battery-electric vehicles can allow for cost-neutral electrification of transportation; however, neither hydrogen nor CO2-based e-fuels are economically sustainable. For building-use, electric resistive heating, electric lighting, and heat pumps are sufficiently low-cost to displace fueled processes. Industry is hardest to electrify due to unfavorable thermodynamic limits of carbon-neutral chemistries and because fueled processes operate near their thermodynamic energy minimums. Electrification, thus, would add costs when thermochemistry is replaced by single-product electrochemistry. However, industrial electrification could be cost neutral using multi-product pathways, once scale economies allow for sufficient capital expenditure reductions relative to single product chemistry.

Coalbed methane is an underappreciated problem of global steel production. While cutting methane emissions in the steel supply chain will not produce green steel overnight, it could reduce the sector’s emissions by the equivalent of a billion tons of carbon annually, and at little cost.
