The role of hydrogen and ammonia in meeting the net zero challenge

The role of hydrogen and ammonia in meeting the net zero challenge CLIMATE CHANGE : SCIENCE AND SOLUTIONS | BRIEFING 4 The role of hydrogen and ammonia in meeting the net zero challenge In brief Hydrogen and ammonia have important potential roles in could be achieved through decarbonisation of production a net zero economy as they have no carbon emissions at for both existing and new applications. [...] Hydrogen and ammonia today 1.1 Background Ammonia (NH3) has higher volumetric energy Hydrogen is the most abundant element in density than hydrogen and is easier to store and the universe and a well-established energy transport. [...] Other applications use it needs a higher concentration in air to be hydrogen as part of a mixture of gases, including flammable, 4% compared to 1.6% for gasoline, the production of methanol used in industrial and its low density and high diffusivity in air 11, 3 applications and chemical manufacture, and the reduces risk as it dissipates rapidly. [...] Low-carbon production and use of hydrogen and ammonia Hydrogen and ammonia offer opportunities Green hydrogen to provide low carbon energy and help reach ‘Green’ hydrogen uses renewable electricity to ‘Green’ hydrogen the target of net-zero emissions by 2050. [...] CLIMATE CHANGE : SCIENCE AND SOLUTIONS HYDROGEN AND AMMONIA 9 3.3 Priorities for research and development • More research and development on To realise the potential of hydrogen and fuel cells to reduce costs and develop ammonia as major contributors to achieving recyclable technologies.
