Hydrogen, also known as H2, will play an important role as an energy carrier, which enables the transfer of energy from one place to another. Indeed, it can help drive the decarbonization of entire industrial sectors

Background There is a race to innovate, develop or create hydrogen production technologies to accelerate energy transition and create a hydrogen economy. Acceptance has been used in social science literature as a lens through which to anticipate possible challenges surrounding hydrogen technologies. However, very few studies

Hydrogen gas'' role in the energy transition has been ascribed enormous potential – offering a solution to several of the challenges faced in making the transition a reality. It could essentially replace fossil fuels with a clean energy source across the economy, with only water as a by-product. It is important to note though that hydrogen

Abstract. Hydrogen is gaining momentum in the current global energy transition framework. In fact a great and widespread enthusiasm is growing up towards it, as indicated by the current worldwide economic and political strategies, which endorse the carbon neutrality by 2030 and a fast transition to clean energy.

Hydrogen is fast becoming the go-to low- and no-carbon fuel to support the energy transition and help power the world''s net-zero ambitions.

Phase 1 (from 2020 to 2024): installation of at least 6 gigawatts (GW) of electrolyser capacity in the EU by 2024, corresponding to production of up to 1 million tonnes of renewable hydrogen. This aim was not realised. Phase 2 (from 2025 to 2030): installation of at least 40 GW of electrolyser capacity in the EU by 2030, with a further

c. Alternative energy carrier for transporting renewable energy converted to hydrogen over long distances solving temporal and spatial mismatch of VRES and demand. The transport options may include liquid hydrogen tankers, trunk pipelines, etc. Special focus on off-shore wind conversion to hydrogen offshore (electrolyzers installed directly on off-shore

Global hydrogen production by technology in the Net Zero Scenario, 2019-2030. IEA. Licence: CC BY 4.0. Dedicated hydrogen production today is primarily based on fossil fuel technologies, with around a sixth of the global hydrogen supply coming from "by-product" hydrogen, mainly in the petrochemical industry.

Funding gap. Despite hydrogen''s momentum, a significant investment gap remains for it to fully contribute to decarbonization. Achieving a pathway to net zero will require additional direct investments of $460 billion by 2030 1 —closing the gap between the $240 billion of announced projects and $700 billion in required investments.

4. Trade, security, and interdependence. 5. The root causes of geopolitical instability – and hydrogen''s role in addressing them. 6. Policy considerations and the way forward. The International Renewable Energy Agency (IRENA) is an intergovernmental organisation supporting countries in their transition to a sustainable energy future.

Hydrogen is a naturally occurring gas, and it is the most abundant substance in the universe. (The word in Greek means "water former" because hydrogen creates water when burned.) Clean hydrogen is hydrogen produced with very low or zero carbon emissions. The term also refers to derivative products of hydrogen, including

April 2021. In its new report Making the Hydrogen Economy Possible: Accelerating clean hydrogen in an electrified economy, the ETC outlines the role of clean hydrogen in achieving a highly electrified net-zero economy. The report sets out how a combination of private-sector collaboration and policy support can drive the initial ramp up of clean

In this paper we explore the role of hydrogen in the energy transition, including its potential, recent achievements, and challenges to its deployment. We also offer recommendations to ensure

Abstract and Figures. Natural Hydrogen is a new, clean and low-carbon source of hydrogen that is produced by the Earth, and can migrate and accumulate in geological reservoirs. Its exploration has

This comparative review explores the pivotal role of hydrogen in the global energy transition towards a low-carbon future. The study provides an exhaustive

Grey, blue, and green hydrogen: A comprehensive review of production methods and prospects for zero-emission energy. ABSTRACT Energy is the linchpin for economic development despite its generation deficit worldwide. Hydrogen can be used as an alternative energy source to meet the requirement that it emits zero to.

Hydrogen is the flagship of the green energy transition. •. National policies and directives are focused on supporting carbon-neutral society based on hydrogen. •. Progress of hydrogen usage is evident in the expansion of hydrogen infrastructure. •. Social acceptance of hydrogen technology is steadily increasing. •.

This work shows the progress of hydrogen taking its place as a key factor of the future green energy society. It reviews recent developments of hydrogen

As the world transitions beyond fossil fuels towards a more sustainable and low-carbon future, hydrogen is becoming a key player in the energy mix. Hydrogen is

In this section we will discuss the energy level of the electron of a hydrogen atom, and how it changes as the electron undergoes transition. According to Bohr's theory, electrons of an atom revolve around the nucleus

Hydrogen is a promising commodity, a renewable secondary energy source, and feedstock alike, to meet greenhouse gas emissions targets and promote economic decarbonization. A common goal pursued by many countries, the hydrogen economy receives a blending of public and private capital. After European Green Deal,

For hydrogen to contribute to the energy transition, a scale-up over the next decade is critical. Learn more about McKinsey''s Oil & Gas Practice. What is needed

The hydrogen supply chain includes a large number of steps, resulting in additional energy losses, and while much focus is put on hydrogen generation costs, its transport and storage should not be

Additional investments in research are needed to decrease the full-cycle costs of electricity storage via hydrogen and support a more effective energy transition []. Climate strategies based on power generation from imported hydrogen have been proposed for regions with low local renewable potential, mostly in Japan [ 105, 106 ].
