Introduction. Nowadays, the technology of renewable-energy-powered green hydrogen production is one method that is increasingly being regarded as an approach to lower emissions of greenhouse gases (GHGs) and environmental pollution in the transition towards worldwide decarbonization [1, 2].However, there is a societal realization that fossil fuels are
Below, a set of mutually reinforcing priority actions for policymakers and industry for 2022 to 2023 to progress from proposals to investments, scale up hydrogen deployment in regions and enable global hydrogen trade (Exhibit 1). These are critical for moving from ambition to action, accelerating hydrogen deployment.
Focusing on hydrogen''s potentially major role in meeting international energy and climate goals, this year''s Review aims to help decision makers fine-tune strategies to attract investment and facilitate deployment of hydrogen technologies while also creating demand for hydrogen and hydrogen-based fuels. It compares real-world developments
Global Hydrogen Review 2022 P AGE | 9 Executive summary IEA policy recommendations to accelerate low-emission hydrogen production and use Move from announcements to policy implementation: the focus of governments on defining the role of hydrogen in their energy strategies in recent years has helped industry understand the
Hydrogen has the highest energy content per unit mass (120 MJ/kg H 2), but its volumetric energy density is quite low owing to its extremely low density at ordinary temperature and pressure conditions.At standard atmospheric pressure and 25 °C, under ideal gas conditions, the density of hydrogen is only 0.0824 kg/m 3 where the air density under the same conditions
The global energy crisis underscores the need for policy to align energy security needs with climate goals. Hydrogen can contribute to energy security by decreasing dependency on fossil fuels, either by replacing fossil fuels in end-use applications or by shifting fossil-based hydrogen production to renewable hydrogen. The development of an
Below, a set of mutually reinforcing priority actions for policymakers and industry for 2022 to 2023 to progress from proposals to investments, scale up hydrogen deployment in regions and
Hydrogen gas-based energy is in focus today due to its availability in plenty of combined forms such as water, hydrocarbons, natural gases, etc. However, its storage and transportation are major challenges due to the low volumetric density and explosive nature of hydrogen. The scientific community is in search of suitable, economically viable
Energy density and specific energy of various fuels and energy storage systems. The higher energy density of hydrogen-derived commodities effectively increases the distance that energy can be transported in a cost-effective way, connecting low-cost renewable energy regions with demand centres that have either limited renewable potential or

The study presents a comprehensive review on the utilization of hydrogen as an energy carrier, examining its properties, storage methods, associated challenges, and potential future implications. Hydrogen, due to its high energy content and clean combustion, has emerged as a promising alternative to fossil fuels in the quest for sustainable energy. Despite its
ambitious targets for the production of hydrogen. This includes increasing member states'' hydrogen production capacity and stipulates specific targets, for example the undertaking to
However, its energy-to-volume ratio, exemplified by liquid hydrogen''s 8.5 MJ.L −1 versus gasoline''s 32.6 MJ.L −1, presents a challenge, requiring a larger volume for equivalent energy. In addition, this review employs life cycle assessment (LCA) to evaluate hydrogen''s full life cycle, including production, storage, and utilization. Through
On 10 February 2023, in line with the requirements of the Renewable Energy Directive, the Commission adopted two delegated regulations: one defining rules on renewable hydrogen production and clarifying the additionality criteria for renewable electricity, and another setting out a methodology to calculate lifecycle GHG emissions.
Hydrogen networks and storage . Hydrogen T&S infrastructure are key strategic assets within a fully decarbonised economy, providing the link between hydrogen production and demand. In
All 20 action points of the EU hydrogen strategy, which were implemented and delivered by the beginning of 2022, aimed at boosting demand for and scaling up renewable energy production in the EU, designing and

In 2022, 70% of the energy requirement for dedicated hydrogen production was met with natural gas and around 30% with coal (mostly used in China, which alone accounted for 90% of global coal consumption for hydrogen production).
Referring to the emissions intensity of hydrogen production in regulations and certifications, based on a common methodology for determining the emissions, in line with the recommendations of the IEA''s report for the 2023 G7 Climate,

Hydrogen has been acknowledged as a vital component in the shift toward an economy with fewer GHGs. The essential components of the transition are the methods of Hydrogen Production, Transportation, Storage, and Utilization (HPTSU), as shown in Fig. 1.Several techniques employed to produce hydrogen to meet the increasing need for
ambitious targets for the production of hydrogen. This includes increasing member states'' hydrogen production capacity and stipulates specific targets, for example the undertaking to install at least 6 GW of renewable hydrogen electrolysers in the EU by 2024 and 40 GW of renewable hydrogen electrolysers by 2030.
In 2022, 70% of the energy requirement for dedicated hydrogen production was met with natural gas and around 30% with coal (mostly used in China, which alone accounted for 90% of global coal consumption for hydrogen production).
Ensuring additionality is another legislative requirement for the deployment of renewable hydrogen. The European Commission is contemplating to apply this principle as of 2027, which should allow the sector sufficient time to synchronise the development of both renewable power plants and hydrogen production facilities.
All 20 action points of the EU hydrogen strategy, which were implemented and delivered by the beginning of 2022, aimed at boosting demand for and scaling up renewable energy production in the EU, designing and enabling a supportive legislative framework and strengthening the EU’s leading role in the international hydrogen market.
Global hydrogen demand reached 95 Mt in 2022, almost 3% more than in 2021. Hydrogen demand remains concentrated in traditional applications in the refining and industrial sectors (including chemicals and natural gas-based Direct Iron Reduction [DRI]), with very limited penetration in new applications.
Focusing on hydrogen’s potentially major role in meeting international energy and climate goals, this year’s Review aims to help decision makers fine-tune strategies to attract investment and facilitate deployment of hydrogen technologies while also creating demand for hydrogen and hydrogen-based fuels.
Targets for the deployment of hydrogen production technologies are growing, particularly on electrolysis capacity, with national targets reaching an aggregate of 160-210 GW, which accounts for 30-40% of the installed electrolysis capacity by 2030 in the NZE Scenario.
