The potential of hydrogen to accelerate the energy transition
The potential of hydrogen to accelerate the energy transition
Publication | October 2019
Hydrogen as an energy vector is back in fashion due to its potential to support the transition to a decarbonized energy system required to meet the emission reduction goals of the Paris Agreement. Hydrogen made from renewable or low carbon electricity could help decarbonise those sectors that have been less amenable to electrification, such as transport and heating. Hydrogen produced in this way can be characterised as a synthetic “green” fuel and may part-replace or displace conventional fossil fuels in the energy mix.
Today, the majority of hydrogen used, whether in industrial applications or as a transport fuel, is produced by reforming methane gas. In its report, “The Future of Hydrogen” published in June 2019, the International Energy Agency (IEA) estimates that the majority of hydrogen produced comes from fossil fuels with less than 0.7 percent of current hydrogen production coming from renewables or from fossil fuel plants equipped with carbon capture use and storage. The IEA estimates that this industry of itself accounts for 830 million tonnes of carbon dioxide per year (MtCO2/yr). The production of hydrogen by electrolysis of water using low carbon electricity could reduce emissions in hydrogen production.
Perhaps of greater interest is the potential for hydrogen to help to decarbonize those sectors that have been harder to electrify. The market for green or low carbon hydrogen is expected to change in the coming years as there is potential for synergy between hydrogen and the production of renewable or nuclear energy. However, the cost of low carbon hydrogen production is still a significant barrier. The IEA reports that the cost of electricity is the single most significant cost in electrolytic hydrogen production. Cheaper, low carbon power sources therefore represent an opportunity. Other barriers will also need to be addressed, with commentators citing the cost of electrolyzers and a need for a minimum number of operating hours for economic viability.
Once produced, low-carbon hydrogen can be stored and transported, making it a more flexible energy vector than electricity. The IEA observes that the development of storage and transportation markets will be important if large-scale, international hydrogen value-chains are to emerge. Storage of hydrogen is possible in compressed gas or liquefied form, in tanks or in geological storage such as salt-caverns or depleted gas wells. The appropriate storage option will often depend on the volumes stored, the duration of the storage and the available geology. Storage as ammonia is also possible and may be attractive due to its higher energy density. Transport options include via tanker, pipeline (blended with methane gas or dedicated) or by vessel.
The end uses for hydrogen are multiple and include applications in the industrial sector, transport and heating, as well as in the power sector.
