ILLUSTRATIVE PATHWAYS TO 100 PERCENT ZERO CARBON POWER BY 2035 WITHOUT INCREASING CUSTOMER COSTS
The document explores five supply-side pathways to reach 100 percent zero carbon power in the U.S. by 2035. It argues that while the final 10 percent of decarbonization is the most expensive, it can be achieved at a cost that keeps average wholesale rates similar to the 2020 average of 5.2 cents/kWh. The analyzed pathways include three green hydrogen options (fuel cells, turbine retrofits, and synthetic methane) and two carbon capture options (CCS retrofits and Direct Air Capture). The report highlights that green hydrogen production costs could drop to $1.50/kg by 2030 due to falling solar and wind costs and cheaper electrolyzers.

Comparing Electric Vehicles
The document compares four categories of electrified vehicles. Conventional hybrids use regenerative braking to charge batteries and improve fuel economy. PHEVs combine an internal combustion engine with a plug-in battery, allowing for short distances of gasoline-free driving. BEVs run exclusively on electricity, producing no tailpipe emissions and offering the longest electric ranges. FCEVs use hydrogen gas to generate electricity, emitting only water from the tailpipe, though their environmental impact depends on the hydrogen production method and infrastructure is currently limited primarily to California.
