During the ongoing COP26 event, much has been written about the financial requirements of supporting a clean energy transition, including the necessary reduction in subsidies of fossil fuels and the increase in clean energy technology investment. But what are these technologies? Three key emerging sectors that are set to play a fundamental role in the future of the global energy industry include hydrogen, carbon capture, utilisation and storage (CCUS) and bioenergy/biofuels.
Hydrogen is currently playing a leading role in the energy transition, enjoying unprecedented momentum across a range of sectors. The most in-demand area for hydrogen deployment has been in mobility, with passenger cars, vehicle refuelling stations and buses taking precedence. Electrolysers, heat and power for buildings, power generation and industry have also given rise to the widespread adoption of hydrogen.
The electrolyser is a specific technology that will significantly support decarbonisation of industry. Through a process called electrolysis, this technology allows for the production of so-called green hydrogen, hydrogen that is produced using renewable energy. This differs from brown or grey hydrogen, which is derived from hydrocarbon-rich feedstock and has a large carbon footprint.
