The Contribution of Natural Gas Vehicles to Sustainable Transport

Abstract

The International Energy Agency (IEA), an autonomous agency, was established in November 1974. Its mandate is two-fold: to promote energy security amongst its member countries through collective response to physical disruptions in oil supply and to advise member countries on sound energy policy.The IEA carries out a comprehensive programme of energy co-operation among 28 advanced economies, each of which is obliged to hold oil stocks equivalent to 90 days of its net imports. The Agency aims to:n Secure member countries' access to reliable and ample supplies of all forms of energy; in particular, through maintaining effective emergency response capabilities in case of oil supply disruptions. n Promote sustainable energy policies that spur economic growth and environmental protection in a global context -particularly in terms of reducing greenhouse-gas emissions that contribute to climate change. n Improve transparency of international markets through collection and analysis of energy data. n Support global collaboration on energy technology to secure future energy supplies and mitigate their environmental impact, including through improved energy efficiency and development and deployment of low-carbon technologies. n Find solutions to global energy challenges through engagement and dialogue with non-member countries, industry, international organisations and other stakeholders.

Structure-activity relationship in Pd/CeO2 methane oxidation catalysts

“…The synergy between Pd and CeO2 is widely exploited for the catalytic oxidation of methane, a topic that is object of increasing attention due to the global warming potential of methane (~30 times that of CO2) associated with the spreading of natural gas fueled vehicles (NGVs). NGVs have more than doubled their number worldwide in the years 2010-2019 (http://www.iangv.org/current-ngv-stats/ accessed on August 29 th , 2019), thanks to their lower pollutant emissions compared to traditional diesel or gasoline engines [7]. A vehicle running on natural gas can be equipped with a lean burn or a stoichiometric engine, the first technology being mostly applied to heavy duty vehicles (i.e.…”
