The program expects to allocate up to AUD2bn (US$1.3bn) in funding to accelerate the development of large-scale renewable hydrogen projects across Australia.

Renewable hydrogen is also part of a broader plan and series of directives aiming at increasing the share of renewable energies in EU’s energy consumption.

However, the country reaffirmed its commitment to a €4bn subsidy package for producers of low-carbon hydrogen (compared to H2 from fossil fuels) to support the commercialisation and industrialisation of early-stage hydrogen projects and the development of necessary regulatory frameworks and infrastructure.

In the global race to achieve net-zero emissions, India stands at the threshold of a transformative clean energy revolution. Green hydrogen, a fuel produced through water electrolysis using renewable sources, has captured attention for its immense potential to cut carbon emissions and drive economic growth.

An integrated approach to drive sustainable development goals opens new pathways in green hydrogen applications in industries, utilities and transport sector.

As part of the H2Hubs program, DOE is committing up to $1.2 billion of federal cost share for the Gulf Coast Hydrogen Hub—led by HyVelocity (HyV) and up to $1 billion of federal cost share for the Midwest Hydrogen Hub—led by the Midwest Alliance for Clean Hydrogen LLC (MachH2).

Ammonia, which consists of nitrogen and hydrogen, boasts a high energy density, making it a practical medium for hydrogen storage and transport.

Green hydrogen, generated through water electrolysis powered by renewable energy, holds promise for nearly zero emissions. However, as interest grows in low-carbon hydrogen, the industry is moving beyond simplistic colour categorizations.

Hydrogen's low volumetric energy density poses a significant challenge. Traditional storage methods, such as high-pressure tanks, require robust and often heavy containers, which limit their practicality. Advanced solutions like cryogenic storage and novel materials are being explored to mitigate this issue.

Hydrogen, often touted as the "fuel of the future," has immense potential to decarbonize key sectors such as transportation, manufacturing, and energy storage.
