ORNL team discovers mechanism behind direct ethanol-to-hydrocarbon conversion; implications for energy efficiency and cost of upgrading

Green Car Congress

The research, supported by DOE’s BioEnergy Technologies Office (BETO), has implications for the energy efficiency and cost of catalytic upgrading technologies proposed for use in bio-refineries. The addition of biomass derived ethanol to gasoline in the transportation sector is an important step in the utilization of renewable energy.

NREL shows graded catalytic-protective layer boosts longevity of high-efficiency photocathodes for renewable hydrogen

Green Car Congress

Researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a method which boosts the longevity of high-efficiency photocathodes in photoelectrochemical water-splitting devices. Turner’s device held the record for the highest solar-to-hydrogen efficiency, until it was finally eclipsed in 2015.

Bauhaus Luftfahrt analysis finds solar thermochemical jet fuel production viable only if CO2 captured from renewable sources and not flue gases

Green Car Congress

According to their analysis, published in the ACS journal Environmental Science & Technology , favorable assumptions for all involved process steps (30% thermochemical energy conversion efficiency; 3000 kWh/(m 2 a) solar irradiation, low CO 2 and heliostat costs) result in jet fuel production costs of €1.28/L kg CO 2 ‐equiv /L.

DOE reports progress on development of low-carbon and renewable sources of hydrogen production

Green Car Congress

The objective of the Hydrogen Production sub-program is to reduce the cost of hydrogen dispensed at the pump to a cost that is competitive on a cents-per-mile basis with competing vehicle technologies. Based on current analysis, this translates to a hydrogen threshold cost of. Source: DOE. Click to enlarge.

Renewable Chemicals and Advanced Biofuels Company Gevo Files for IPO; Non-binding Letter of Intent with United Airlines for Renewable Jet Fuel

Green Car Congress

Gevo has a low capital cost retrofit strategy for ethanol plants to produce isobutanol for direct use; for use in the production of plastics, materials, rubber and other polymers; and for use in the production of hydrocarbon fuels. The production of this quantity of renewable jet fuel will require approximately 205 MGPY of isobutanol.

Electrification Coalition releases Fleet Electrification Roadmap; suggests fleet adoption could put a cumulative 200,000 PHEVs and EVs on the road by 2015

Green Car Congress

The analysis in the EC roadmap concludes that fleet adoption of grid-electric vehicles (PHEVs and EVs) could lead to a cumulative 200,000 units on the road by 2015. The Fleet Roadmap also presents the results of detailed total cost of ownership modeling for PHEVs and EVs in fleet applications for a number of industries. Earlier post.).
