Hydrogen and its derivatives, including ammonia, are widely considered a cornerstone of our global energy transition, climate change actions, and sustainable energy security. With more than 70 countries currently committed to reaching net zero, renewable energy development is rapidly increasing and becoming more widespread.

To reach our 2050 climate goals, critical work is required in securing the supply and resilience of these increasing renewable energy systems, including new routes to markets, alternative fuel production, increasing shares of renewable electricity, mitigating the risk of curtailment, and opening access to countries with as yet limited green energy resources.

Delivering net zero also requires decarbonisation at the scale of the full value chain of an energy project, including production, support infrastructure and energy transportation. 

Green Hydrogen – a highly versatile, clean and safe energy carrier, produces zero emissions at the point of consumption. For this reason, hydrogen can benefit various sectors including renewables, maritime, oil & gas, and other industries boasting four key opportunities:

  • As energy storage or as an energy carrier, green hydrogen (produced from renewable energy sources via electrolysis or other methods) can improve potentially electricity grid stability and broaden access to net-zero energy resources
  • Alternative fuels can power ships and heavy-duty vehicles helping the decarbonization of the maritime industry, mobile/transportation sectors, and other industries.
  • Higher capacity of hydrogen and ammonia transport/export could be allowed by ships and/or pipelines
  • Carbon capture, utilization, and large-scale storage of CO2, hydrogen and ammonia

Many countries are rapidly recognising the potential hydrogen can offer. The EU issued its hydrogen strategy in 2021, calling for 6 GW of capacity by 2024 and 40 GW by 2030. But, as with all new technologies, the development and integration of hydrogen are not without their challenges.

Opportunities with Green Hydrogen

100% sustainable: does not emit pollutants at combustion or production

Storable: easy to store, enabling more widespread and versatile consumption, and variable transmission as per supply and demand 

Versatile: can be transformed into electricity or synthetic gas and used for commercial, industrial or mobility purposes

Challenges with Green Hydrogen

High cost: generated from the electrolysis of renewable energy sources, means its cost-competitiveness is dependent as well on the cost-competitiveness of the energy resource

High energy consumption: hydrogen production in general and green hydrogen, in particular, requires more energy than other fuels

Safety: volatile and flammable. Therefore, extensive safety measures need to be taken throughout the life-cycle of a project
