Lawrence Livermore publishes state-by-state energy/water Sankey diagrams

Green Car Congress

For the first time, Lawrence Livermore National Laboratory (LLNL) has published state-by-state energy and water Sankey diagrams in one location so that analysts and policymakers can find all the information they need in one place. General location of energy and water categories. Energy and water generally “flows” from left to right.

Argonne LCA study finds many alternative fuels consume more water than petroleum and natural gas fuels

Green Car Congress

Researchers at Argonne National Laboratory have analyzed the water consumption for transportation fuels in the United States using an extended lifecycle system boundary that includes the water embedded in intermediate processing steps. Increases in population, energy and food demand now strain previously abundant sources of water.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. Earlier post.). Earlier post.) Currently the company has a 4,000 metric ton/year production capacity.

Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

Gasoline section shows results for fuel derived from both conventional oil and oil sands. The fracture fluid is typically water-based and contains proppants to maintain fracture openings once pumping of the fluid has ceased. Expansion bars show the components of fuel production.

Understanding the variability of GHG life cycle studies of oil sands production

Green Car Congress

Full-fuel-cycle GHG emissions estimates for reformulated gasoline pathways by LCA study. He found that the variation in oil sands GHG estimates is due to a variety of causes. These include oil sands, enhanced oil recovery, coal-to-liquids and gas-to-liquids synthetic fuels, and oil shale. 85%); water (5?10%);

Argonne updates GREET and AFLEET tools for transportation technologies analysis

Green Car Congress

Added biomass-derived high octane gasoline via indirect liquefaction and renewable gasoline/diesel pathways from fast pyrolysis. Implemented new pathways for fuel cell electric medium- and heavy-duty vehicles powered by gaseous hydrogen. Also updated energy and water consumption for lithium-ion battery manufacturing.
