Hydrogen – A Catalyst For The Energy Transition

The Paris Agreement - an international treaty on climate change - sets a key objective for signatory countries to reduce greenhouse gas emissions and limit increases in global temperature in this century to 2 degrees Celsius above preindustrial levels. In a 2018 special report, the Intergovernmental Panel on Climate Change went further and recommended that countries must bring carbon dioxide emissions to net zero by 2050 to keep global warming to within 1.5°C of pre-industrial levels. Key to achieving these targets is what is commonly referred to as energy transition - the switch from a fossil fuel-based energy system with high carbon emissions to a carbon neutral system.

However, the path to decarbonisation is not without challenges. While renewable energy sources such as wind, hydro and solar are forming an increasingly significant part of the energy mix, it is far from a standalone solution as certain inherent features of renewable technologies, such as higher
