Renewable hydrogen is promoted in the EU via several instruments including the targets set out in the Renewable Energy Directive . To ensure that the hydrogen is produced from renewable energy sources and achieves at least 70% greenhouse gas emissions savings, the Commission adopted in June 2023 two delegated acts.
3.1 Status. The current energy shortage promotes the development of photocatalytic hydrogen production technology. There are about 5% ultraviolet light, 46% visible light and 49% near-infrared light in the solar spectrum. At present, most of the known semiconductors respond to ultraviolet and visible light.
Producing hydrogen from low-carbon energy is costly at the moment. IEA analysis finds that the cost of producing hydrogen from renewable electricity could fall 30% by 2030 as a result of declining costs of renewables and the scaling up of
This article gives an overview of the state-of-the-art hydrogen production technologies using renewable and sustainable energy resources. Hydrogen from supercritical water gasification (SCWG) of biomass is the most cost effective thermochemical process. Highly moisturized biomass is utilized directly in SCWG without any high cost
Hydrogen can be generated from renewable energy sources such as solar or wind energy or non-renewable energy such as fossil fuels, particularly methane reforming. In addition, the integration of nuclear energy as a source of electricity for hydrogen production plants has been recently investigated [ 75 ].
Hydrogen production should be conducted by integrating low-CO 2 feedstocks and renewable energy sources [13] to reduce the environmental impact. Alongside the production of hydrogen from natural gas via steam reforming, there are other renewable and
To determine when renewable hydrogen production is economically viable, we first consider the average annual contribution margin of renewable energy on its own. The average value of all p e (t)CF
Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water. Hydrogen can be produced from a variety of domestic resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. These qualities make it an attractive fuel option for transportation and electricity generation applications.
Hydrogen production from renewable electricity is expected to play an important role in reaching long-term decarbonisation goals and improving energy security. While less than 1% of global hydrogen production comes from renewable energy sources today, renewable hydrogen is receiving increasing policy attention.
The urbanization and increase in the human population has significantly influenced the global energy demands. The utilization of non-renewable fossil fuel-based energy infrastructure involves air pollution, global warming due to CO 2 emissions, greenhouse gas emissions, acid rains, diminishing energy resources, and environmental
The technique of producing hydrogen by utilizing green and renewable energy sources is called green hydrogen production. Therefore, by implementing this technique, hydrogen will become a sustainable and clean energy source by lowering greenhouse gas emissions and reducing our reliance on fossil fuels.
But there are encouraging signs of progress. Global capacity of electrolysers, which are needed to produce hydrogen from electricity, doubled over the last five years to reach just over 300 MW by mid-2021. Around 350 projects currently under development could bring global capacity up to 54 GW by 2030. Another 40 projects accounting for more
The International Renewable Energy Agency (IRENA) is an intergovernmental organisation that supports countries in their transition to a sustainable energy future and serves as the principal platform for international co-operation, a centre of excellence and a repository of policy, technology, resource and financial knowledge on renewable energy.

In this case, H 2 production is done using only RES electricity, which means that the expensive infrastructure to produce H 2 may be underused due to the reduced availability of the RES electricity. Usually, this fact reduces the H 2 plant usage factor to below 50%, although this equipment could reach a usage factor above 95% [21] .

Green hydrogen is defined as hydrogen produced by splitting water into hydrogen and oxygen using renewable electricity. This is a very different pathway compared to both grey and blue. Grey hydrogen is traditionally produced from methane (CH4), split with steam into CO2 – the main culprit for climate change – and H2, hydrogen.
