Low carbon hydrogen (whether based on renewable or nuclear electricity, or fossil fuels with carbon capture) is a means to decarbonise sectors of the economy which are hard to electrify. Its business model is heavily dependent on government intervention (e.g. mandatory targets, subsidies,...

Rund 28% des jährlichen Endenergieverbrauchs in Deutschland entfällt laut der Arbeitsgemeinschaft Energiebilanzen (AGEB) auf den Sektor der privaten Haushalte. Weitere 30% der Endenergie werden vom Verkehrssektor verbraucht. Haushalte verwenden Energie insbesondere für die Erzeugung von...

Hydrogen energy systems (HES) are increasingly recognized as pivotal in cutting global carbon dioxide (CO2) emissions, especially in transportation, power generation, and industrial sectors. This paper offers a comprehensive review of HES, emphasizing their diverse applications and economic...

The transition from fossil fuels to carbon-neutral energy sources is necessary to reduce greenhouse gas (GHG) emissions and combat climate change. Hydrogen (H2) provides a promising path to harness fossil fuels to reduce emissions in sectors such as transportation. However, regional economic...

Climate-neutral hydrogen is set to play a crucial role in decarbonizing Europe by 2050. Yet, assumptions on hydrogen imports vary widely across existing studies - ranging from fully flexible to fixed import volumes - often neglecting the modalities of future hydrogen trade such as long-term...

China is the world’s largest producer and consumer of hydrogen. The country has adopted a domestic strategy that targets significant growth in hydrogen consumption and production. Given the importance of hydrogen in the low-carbon energy transition, it is critical to understand China’s...

The European Commission has identified hydrogen as a key part of its decarbonisation strategy. The 2022 REPowerEU Strategy set a target of 20MT consumption of renewable hydrogen by 2030. The Commission is keen to promote a single European market in hydrogen, similar to the current one for...

The transition of the energy sector from using conventional sources to sustainable sources paves the way for the exploration of various new energy sources. Since the past classifications are often based on subjective criteria such as whether an energy source is either renewable or fossil fuel....

Hydrogen’s production versatility, coupled with its potential as an energy vector, positions it as a potentially important fuel for the future. It can be sourced in many different ways, and has the ability to meet many applications, both in existing and future technology, and this means that...

Usage of hydrogen energy is low - just over one in ten has used it - but awareness is high at 82%. Approximately one in ten have never heard of hydrogen energy. The overall image of hydrogen is positive in terms of environmental impact compared to fossil and nuclear energy, although gasoline and...

Usage of hydrogen energy is low - just over one in ten has used it - but awareness is high at 82%. Approximately one in ten have never heard of hydrogen energy. The overall image of hydrogen is positive in terms of environmental impact compared to fossil and nuclear energy, although gasoline and...

The transition to a cleaner and greener energy production requires storing the energy produced from renewable energy sources. Hydrogen is an promising vector for storing the surplus energy from RES for use at a later time. The present study uses a discrete choice experiment and a mixed logit...

Hot-electron-induced CO2 hydrogenation is a promising pathway for solar-to-chemical energy conversion under mild conditions. Herein, we designed a unique “antenna–reactor” architecture with surface alloyed Au@AuRu plasmonic nanoparticles (NPs) loaded on g-C3N4 (Au@AuRu/g-C3N4) to achieve...

As a manufactured fuel, hydrogen can be produced in a decentralized way in most countries around the world. This means, even in a net zero economy, the global trade of hydrogen could look quite different to the current international trade in fossil fuels, including natural gas. With further...

Legislation often empowers agencies to develop rules, but legal challenges may create uncertainty, thereby increasing firm costs, delaying policy objectives, and affecting externalities. This paper investigates policy uncertainty surrounding the Mercury and Air Toxics Standard, estimating a...

The energy transition is driving governments and industries to adopt various measures to reduce their climate impacts while maintaining the stability of their economy. Hydrogen technologies are one of the central topics in the energy transition. Different nations have different stances on it....

The world's major countries are aggressively preparing national strategic countermeasures in response to climate change, the fourth industrial revolution and tightening environmental regulations.Korea is also preparing for the new energy paradigm in earnest. The government is working on a...

Hydrogen fuel-cell vehicles (HFVs) have been proposed as a promising green transportation alternative. For regions with renewable energy curtailment (due to insufficient demand or lack of transmission capacity), promoting HFVs can achieve the dual benefit of reducing curtailment of renewables...

The recent sharp decline in the cost of renewable energy suggests that the production of hydrogen from renewable power through a Power-to-Gas process might become more economical. Here we examine this alternative from the perspective of an investor who considers a hybrid energy system that...

The transition of Malaysia from fossil fuels to renewable energy sources provides significant challenges and opportunities for various energy sectors. Incorporation of H2 in the primary energy mix requires a deal of complexity in its relation to production, transportation, and end-use. The...

Energy structure adjustment, European green agreements, and carbon neutral and peak carbon policies have been launched by governments around the world to reduce carbon emissions, increase the proportion of clean and renewable energy (e.g.,hydrogen), and thereby mitigate or stop climate warming...

FCH JU projects are optimising hydrogen tanks for vehicles with a bold new approach to shapes, materials and manufacturing. Results have boosted business for industry partners and highlight how research and innovation are key to driving this critical fuel cell technology forward.

This year's edition of the World Energy Investment provides a full update on the investment picture in 2022 and an initial reading of the emerging picture for 2023. The report provides a global benchmark for tracking capital flows in the energy sector and examines how investors are assessing...
