ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

The ICCT has conducted a comprehensive global and temporal life-cycle assessment of GHG emissions from a variety of alternative passenger car powertrains and fuels. This study considers the fuel and electricity consumption in average real-world usage instead of solely relying on official test values.

Nucor investing in start-up company Electra developing zero-carbon iron technology

Green Car Congress

This material will be used in the steelmaking process to offset other high-quality metallics that come with higher greenhouse gas emissions. The process developed by Electra produces Low-Temperature Iron (LTI) from commercial and low-grade ores using zero-carbon intermittent electricity.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

SRI developing process for co-gasification of methane and coal to produce liquid transportation fuels; negligible water consumption, no CO2

Green Car Congress

Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. FTS produces only a small fraction of the hydrocarbons needed for fuel and requires extensive recycling. Lifecycle GHG comparison. Click to enlarge.

Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

Electra has raised $85 million to produce Low-Temperature Iron (LTI) from commercial and low-grade ores using zero-carbon intermittent electricity. Electra’s process emits zero carbon dioxide emissions and carries zero green premium, meaning it will cost the same or less than existing production methods powered by fossil fuels.

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. —Curran et al.

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)
