For such, this manuscript aims to review the most recent publications regarding the strategies to improve the phoelectroactivity of WO3 films for water oxidation. In addition, this review aims to graphically highlight and discuss the general trendings of the photocurrent density response and stability...
The hydrogen molecule, consisting of two hydrogen atoms, can be used to produce carbon-free energy. Hydrogen molecules carry a lot of energy; a pound of hydrogen contains almost three times the energy of a pound of gasoline or diesel. However, hydrogen molecules are not abundant on Earth, ma...
Europe has made huge progress in boosting its renewable energy capacity in recent years. For the first time ever, wind and solar power generation topped the share of electricity provided… Uniper Warns: Dutch Hydrogen Network Needs Expensive Pipeline Upgrade ...
Gasoline engineEmissionContour plotsThe increasing demand for energy efficiency and environmental sustainability has driven extensive research into alternative fuels and emission reduction strategies for internal combustion engines. The use of fuel additives, such as hydrogen peroxide and ethanol blends, has ...
the added benefit of increasing the energy density of the storage system. However, gas compression can be energy intensive, so storage at lower pressures should be considered if the system volume is not a major concern. Current price estimates (in 2020) for gaseous hydrogen storage are around ...
While the prices of fuel and food have come down since the war started, they remain elevated. US gasoline at $3.56 a gallon is the highest since August 2015. Crude oil tumbled from its one-year high of $93.68 on Sept. 27, 2023, to $69.34 on Dec. 7, but is back up to $83.66....

Hydrogen is a great energy carrier in relation to weight. The energy value of hydrogen is between 30 and 50 kWh/kg [42]. Since the volumetric energy density of gasoline and diesel fuel are near 8.8 and 10 kWh/liter, respectively, they contain only 12–13 kWh/kg [76]. Since the volume...
The hydrogen fuel-cells convert compressed hydrogen from their fuel tanks into electricity that powers the electric motor in the vehicle, providing a similar range to vehicles powered by internal combustion engines using gasoline or diesel. The chemical reaction between hydrogen and oxygen in the fuel...
