Hydrogen Fuel’s Potential to Decarbonize Aviation

Air travel accounts for about 2.5 percent of global carbon emissions. To reduce emissions from aviation, ZeroAvia is seeking to build the world’s first zero-emission passenger jet powered by hydrogen fuel, which offers three times more energy per kilogram than jet fuel and emits no toxic fumes when combusted. Hydrogen fuel’s higher energy density and capacity for consistent electrical power make it a promising potential energy source for aircraft.

Using Mobile Apps to Improve Air Quality Awareness in Ghana, with Dr. Collins Gameli Hodoli

The human health effects of air pollution and climate change can exacerbate each other and some air pollutants, like black carbon, are both hazardous to human health and powerful greenhouse gasses. We spoke with Dr. Collins Gameli Hodoli about the importance of increasing awareness of poor air quality–through the use of a mobile app he developed–to developing policies to improve air quality in Ghana.
