Due to the fact of global warming and in order to reduce CO2 emissions, vehicles with new energy carriers like batteries, compressed natural gas, and hydrogen as well as different types of biofuels will gather a growing share in the composition of our society´s means of transportation. These new energy carriers will increasingly be found in urban infrastructure environment and in public transportation vehicles, too.
Today´s safety concepts, guidelines and standards are based on design parameters like heat release rates, fire mitigation measures and evacuation concepts that result from the “old” conventional energy carrier risks of vehicles with combustion engines. But using new energy carriers will lead to emerging and new risks like battery fires, flashes from pressure vessels or distribution of inflammable or explosive gases. We may assume that these changing risks will also result in new safety challenges for our society and buildings.
Together with Bundesanstalt für Materialforschung und –prüfung BAM, STUVA e.V. the following aspects will be examined:
