There’s a pile of information doing the rounds about the pollution of the oceans.
Bombardier Transportation (now part of Alstom) introduced a variety of green innovations to reduce CO 2 emissions and pollution in the railway sector. Bombardier is ideally positioned to carry out this greening project, since nearly 50% of the diesel rail fleet in France consists of AGC trains built at Crespin.
Diesel generators release greenhouse gases, particulate matter (PM), volatile organic compounds (VOCs), nitrous oxides (NO x ) and sulfur dioxide (SO 2 ), harmful pollutants that create smog and exacerbate respiratory conditions. This pollution, in turn, may trigger upwards of $31.8 Of these, 20,907 are diesel-fueled.
Siemens Gamesa and Siemens Energy are joining forces to develop an innovative solution that fully integrates an electrolyzer into an offshore wind turbine as a single synchronized system to produce green hydrogen directly. Just 1% of that hydrogen is currently generated from green energy sources.
