Does the aviation sector have its head in the clouds? Indeed, the experts are working hard to make hydrogen a sustainable aviation fuel. For more, read The Hydrogen Economy Will Soon Be Ready For Takeoff, Including Planes and Power Plants.

Key Takeaways

  • A study by Clean Sky 2 and Fuel Cells & Hydrogen 2 says that hydrogen-powered aircraft could be ready for flight as early as 2035.
  • The Bipartisan Infrastructure Law passed a year ago includes up to $7 billion to establish between 6 and 10 regional hydrogen hubs across the country. The goal is to create a network of hydrogen producers and industrial consumers with an interconnected infrastructure to accelerate the use of clean hydrogen.
  • In its Hydrogen Economy Outlook, Bloomberg New Energy Finance says green hydrogen could supply 24% of the world’s energy demands by 2050 while cutting CO2 levels by 34%.
  • To help accelerate the use of green hydrogen, the U.S. Department of Energy is taking an “Earthshot”, launched in June 2021, to reduce the cost of clean hydrogen by 80% to $1 per one kilogram in one decade. Currently, hydrogen from renewable energy costs about $5 per kilogram.
  • The hydrogen hubs will be essential to achieving economies of scale, bringing about price parity and driving adoption.

Path to 100% Perspective

Hydrogen is one of several potential future fuels that can help phase out fossil fuels in favor of renewable energy as part of the final push to decarbonize energy systems. At the moment, hydrogen is the most promising candidate of the P2X fuel for power plants. Hydrogen is carbon-free, has the highest production energy efficiency of the P2X fuels, and with time it is predicted to become the most cost competitive due to low renewable electricity prices. The most sustainable form of hydrogen is green hydrogen, which is produced through electrolysis of water utilizing renewable electricity. Important for green hydrogen production is access to renewable electricity and clean water. Locations with favorable conditions for these will become hydrogen production hubs.
