  • Zero-Carbon Fuels Zero-Carbon Fuels and Marine Shipping: Both a Will and a Way?

    The marine shipping sector consumes around 10 quadrillion Btu of fuel and emits one billion metric tons of carbon dioxide each year. That’s more than all of Germany’s emissions, more than all of Saudi Arabia’s emissions, and roughly equal to the emissions from all passenger vehicles in the United States. By any reasonable measure the

  • Advanced Energy Systems Putting a (Green) Thumb on the Scale: Decarbonizing the Transportation Sector Will Require Policies that Support Specific Technologies

    Technology neutrality is frequently cited as a key positive attribute of the low carbon fuel standard (LCFS) policy approach. By allowing regulated entities to utilize any technology or system that delivers carbon intensity (CI) reductions, LCFS policies can enlist market-driven innovation by opening the decarbonization challenge to an unlimited set of potential solutions. If various […]

  • Advanced Energy Systems Building a Globally Networked Supply of Zero-Carbon Shipping Fuel

    Decarbonizing the global marine shipping sector will require policy, technology, and industrial advancements that are built for the long haul. The changes will have to be implemented over a period of years by a highly-coordinated international network of public and private sector stakeholders. The cooperation of major ports to facilitate the use of zero carbon […]

  • Bioenergy CATF Statement on EPA’s Final 2020 RFS Biofuels Requirements

    BOSTON, December 19, 2019 – The Environmental Protection Agency (EPA) finalized Renewable Fuel Standard (RFS) regulations today that establish the volume of biofuels that must be blended into the United States’ transportation fuel supply in 2020 (and 2021, for biomass-based diesel fuels). “Today’s rule is more evidence that the RFS has veered severely off course.

  • Bioenergy RFS Politics Keep Ping-Ponging and the Environment Keeps Losing

    If a contest was held to identify the Trump Administration’s most haywire, least efficient, most higgledy-piggledy exercise in policymaking, its implementation of the Renewable Fuel Standard would have to be in the running. Surely other policy initiatives have caused more harm in the past three years, environmental and otherwise—but the RFS is no slouch in […]

  • Advanced Energy Systems Moving Forward with Zero-Carbon Hydrogen and Ammonia Fuels

    In April 2018, member countries of the International Maritime Organization (IMO) announced an “initial strategy” for cutting the shipping sector’s greenhouse gas emissions in half by 2050. If the worst consequences of climate change are to be avoided, major industries like international shipping will need to do more than cut their emissions by 50%—but the […]
