The purpose of this request for information is to understand the off-road sector alternative propulsion technology preferences, technologies that seem most promising, and the key barriers to achieving the transition to net-zero emissions by 2050.

Green hydrogen can become an unrivalled tool to replace fossil fuels in those sectors that are more difficult to decarbonise, thus contributing to the fight against climate change. Hydrogen is the most abundant chemical element on the planet; it is present in 75 % of matter. However, we never find it alone, but in the company of other chemical elements such as oxygen forming water or carbon forming organic compounds. Humanity has long used it as a raw material in the chemical industry or metallurgy and as a fuel, but because it cannot be taken directly from nature in its pure state, it needs to “manufacture” it. https://en.wikipedia.org/wiki/Compressed_hydrogen
What is green hydrogen?
Hydrogen is typically produced using fossil fuels, through energy-intensive processes that result in a lot of climate pollution. But hydrogen can also be made using renewable energy to split water molecules into hydrogen and oxygen (“green” hydrogen), or by extracting it from natural gas under conditions in which most carbon dioxide emissions are captured and stored (“blue” hydrogen).
Neither blue nor green hydrogen is available at scale yet, but massive investments are now flowing into the sector and are expected to change that. Made, managed and used properly, hydrogen could bring real climate benefits. But if too much hydrogen escapes, those emissions could reduce the climate benefits relative to fossil energy — especially in the near-term.
Read online hydrogen is today enjoying unprecedented momentum. The world should not miss this unique chance to make hydrogen an important part of our clean and secure energy future. Dr fatih birol hydrogen and energy have a long shared history – powering the first internal combustion engines over 200 years ago to becoming an integral part of the modern refining industry. It is light, storable, energy-dense, and produces no direct emissions of pollutants or greenhouse gases. But for hydrogen to make a significant contribution to clean energy transitions, it needs to be adopted in sectors where it is almost completely absent, such as transport, buildings and power generation.
What is needed for the hydrogen energy market to scale?
In september 2020, the financial magazine barron’s reported that goldman sachs saw the green hydrogen market as a “once-in-a-lifetime opportunity” for investors, predicting that it could be worth $12 trillion by 2050. Policymakers at the european union wrote in august 2020 that a tipping point had been reached for green hydrogen. They cited that the projected power output for planned electrolyzers—essential to making green hydrogen—by 2030 worldwide had increased from 3. 2 to 8. 2 gigawatts (gw) in just a few months (november 2019 to march 2020). A surge in investment and construction across the globe backs these observations.

a global gold rush is underway for a long-overlooked resource that advocates say could play a significant role in the shift away from fossil fuels. Geologic hydrogen, sometimes referred to as white, gold or natural hydrogen, refers to hydrogen gas that is found in its natural form beneath earth's surface. It is thought to be produced by high-temperature reactions between water and iron-ich minerals. Hydrogen has long been billed as one of many potential energy sources that could play a pivotal role in the energy transition, but most of it is produced using fossil fuels such as coal and natural gas, a process that generates significant greenhouse gas emissions.
The race for clean, sustainable energy is heating up, and green hydrogen is poised to take center stage. This versatile fuel has the potential to replace fossil fuels in everything from transportation to heavy industry. There’s just one catch — producing green hydrogen in the massive quantities we need has seemed impossible due to its reliance on a super-rare metal: iridium. But a breakthrough from the riken center for sustainable resource science ( csrs ) in japan could be about to change everything. Their new technique reduces the amount of iridium needed in green hydrogen production by a whopping 95% – a game-changer for scaling up this transformative technology.
