U of I study: synthetic fuels via CO2 conversion and FT not currently economically & environmentally competitive

Green Car Congress

They used currently achievable performance levels for the system components—electrolyzers and the Fischer−Tropsch process—to compute key metrics, including (i) cost of the synthetic fuel; (ii) well-to-gate CO 2 emissions; and (iii) overall energy efficiency. —Li et al. Stubbins, and Paul J. 6b00665.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. If CNG were to be eventually used in hybrids, the advantage of the electric generation/EV option shrinks. Their open access paper is published in the journal Energy.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

In a paper in Nature , they suggest that the use of such redox-active organic molecules instead of redox-active metals represents a new and promising direction for realizing massive electrical energy storage at greatly reduced cost. The design permits larger amounts of energy to be stored at lower cost than with traditional batteries.

Power-to-Gas project awarded DECC grant funding

Green Car Congress

One of the projects to be awarded grant funding is the “P2G BioMet” project, led by Hydrogenics, along with consortium members CNG Services, Electrochaea and National Grid. The Power-to-Gas via Biological Methanation system uses surplus renewable electricity to split apart water (electrolysis), releasing hydrogen and oxygen.

Navigant forecasts transportation demand for hydrogen to accelerate Power-to-Gas growth

Green Car Congress

Navigant Research forecasts that the transportation segment, with hydrogen demand as a catalyst, will jump-start power-to-gas (P2G) demand and further drive down electrolyzer and other infrastructure costs. Navigant notes that P2G offers benefits to the electric grid through the integration of renewable energy sources.

California Hydrogen Business Council says a robust P2G RD&D program should be a priority for the state

Green Car Congress

The case for using Power-to-Gas solutions to store renewable energy is compelling for a number of important use cases, according to a new white paper released by the California Hydrogen Business Council (CHBC). P2G converts electrical energy to chemical energy in the form of hydrogen. Power-to-Gas concept. Click to enlarge.
