Example of public gas station with hE15 next to diesel and regular gasoline in the Netherlands. A 15% hydrous ethanol and 85% gasoline blend, hE15, has been introduced at public gas stations in the Netherlands since 2008. Ethanol fuel specifications worldwide traditionally dictate use of anhydrous ethanol (less than 1% water) for gasoline blending.
Fuel additives in the United States are regulated under section 211 of the Clean Air Act (as amended in January 1995). The Environmental Protection Agency (EPA) requires the registration of all fuel additives which are commercially distributed for use in highway motor vehicles in the United States, [8] and may require testing and ban harmful additives.
Brazil's sugar cane-based industry is far more efficient than the U.S. corn-based industry. Brazilian distillers are able to produce 1 liter of ethanol for $0.19–0.24 (or $0.71–0.90 per gallon), compared with the $0.41–0.46 per liter for corn-based ethanol (or $1.55–1.74 per gallon) (no reliable source referenced).

At a gas station near the Cologne, Germany, airport, Bernd Mueller watches the digits quickly climb on the pump: 22 euros ($23), 23 euros, 24 euros. Across the globe, drivers like Mueller are ...
Vessels containing a porous material are first filled with acetone followed by acetylene, which dissolves into the acetone. One litre of acetone can dissolve around 250 litres of acetylene at a pressure of 10 bars (1.0 MPa). [62] [63] Acetone is used as a solvent by the pharmaceutical industry and as a denaturant in denatured alcohol. [64]
Gas can still travel from Russia to Europe via the Turkstream pipeline, but no longer through Ukraine, cutting gas imports to the EU by around 14 billion cubic metres.
