Process for Hydrogen Production from Sodium Sulfite Solutions Resulting from Capture of SO2 from Coal Flue Gas

Green Car Congress

Alternatively, oxidation of an aqueous Na 2 SO 3 solution can be carried out for the production of high purity clean hydrogen fuel. Results from using the ultraviolet (UV) photolytic process for production of hydrogen from aqueous Na 2 SO 3 solutions showed that the quantum efficiency of hydrogen production can reach 14.4%

Penn State Researchers Use Ionic Liquids to Improve Efficiency of Direct Coal Liquefaction

Green Car Congress

Researchers at Penn State University have shown that certain ionic liquids can be used to fragment, disperse, and partially dissolve coal to such an extent that good contact can be made with catalyst particles by simply mixing these particles with the ionic liquid/coal dispersion for improved efficiency of liquefaction.

Study Finds Availability of Low-CO2 Electricity and Hydrogen May Paradoxically Delay Large-Scale Transition to Electric and/or Hydrogen Vehicle Fleet

Green Car Congress

Left, global light-duty fleet in the electric-favoring case; right, the hydrogen-favoring case. In both electric- and hydrogen-favoring cases, availability of low-carbon electricity and hydrogen prolonged the use of petroleum-fueled ICE vehicles.

Lifecycle analysis finds Fischer-Tropsch diesel from coal and biomass with CCS can use less fossil energy than petroleum diesel, with GHG close to or below zero

Green Car Congress

A new study by Michael Wang and Jeongwoo Han at Argonne National Laboratory and Xiaomin Xie at Shanghai Jiao Tong University assesses the effects of carbon capture and storage (CCS) technology and cellulosic biomass and coal co-feeding in Fischer-Tropsch (FT) plants on energy use and greenhouse gas (GHG) emissions of FT diesel (FTD).

Green Hydrogen Cars: How They are Different?

Get Electric Vehicle

To put it another way, instead of splitting water into hydrogen and oxygen with electricity, these two components are joined to make water and electricity The electricity is then utilized to power the car’s drive train, leaving just water as a waste product. The oxygen comes from the air, while the hydrogen comes from a tank.

China lags in efforts to achieve 2025 green steel goals, analysts say – ET Auto

Baua Electric

But while China has promised to take action to tackle emissions from the sector, it is lagging on targets to replace coal-fired blast furnaces with cleaner electric arc furnace (EAF) technology, which uses recycled scrap rather than iron ore as a raw material.

UCSD team sheds light on mechanism of sulfur embrittlement of nickel

Green Car Congress

Engineers at the University of California San Diego have shed new light on the atomic-level mechanism of the sulfur embrittlement of nickel, a classic problem that has puzzled the scientific community for nearly a century. Examples include oxygen, sulfur, phosphorus and hydrogen embrittlement of other metals and alloys.
