The Liquid fossil fuels (1) enable transportation, (2) power mobile work platforms, and (3) power on-demand for highly variable demands (seasonal heat and peak power). Describes a system that replaces liquid fossil fuels with drop-in biofuels such as gasoline, diesel, and jet fuel. There is no net influx of carbon dioxide into the atmosphere due to the burning of biofuels, as growing biomass removes carbon dioxide from the air. In addition, when properly managed, biofuel systems can isolate large amounts of carbon as soil organic matter, improve soil fertility and provide other environmental services. In the United States, liquid biofuels have the potential to replace all liquid fossil fuels. The required system has two main functions. First, the heat and hydrogen for converting biomass to high quality liquid fuels is provided by external low carbon energy sources, nuclear power, or fossil fuels with carbon recovery and sequestration. Second, it requires a very large biore finery to effectively compete with fossil fuels. This is equivalent to 250,000 barrels of oil refinery per day.
