most of our supplies are "gray" hydrogen, which is made fromnatural gas. Gray hydrogen does nothing to reduce the climate impact offossil fuels, becausecarbon dioxideis produced as awaste productand dumped into the atmosphere.
Some well known alternative fuels include biodiesel, ethanol, butanol,chemically stored electricity (batteries & fuel cells), hydrogen, methane, natural gas, vegetable oil,biomass, & peanut oil.In the year 2000, there were about eight million vehicles around the world that ran on alternativefuels,...
Hydrogen fuel, particularly green H2, is an appealing form of renewable energy for a number of reasons. It is highly abundant as it is a component of water – it can even beproduced with sea water– and produces only water as its emissions when it is used. H2 has a spectrum of potenti...
Grey hydrogen, which accounts for roughly 95% of the hydrogen produced globally, is mainly used in industrial applications and is produced using fossil fuels, such as natural gas or methane, through steam reforming Brown hydrogen, which is produced using other fossil fuels such as brown (lignite)...

The Outlook for Hydrogen from Wind While only a fraction of today’s energy mix, hydrogen produced using wind energy could become a key component in a global zero-carbon future. DOE’s Hydrogen and Fuel Cell Technologies Office is looking at scenarios showing potential for 5X growth in hydrogen...
However, using hydrogen as a reductant prompts concerns about hydrogen embrittlement in steel products. This raises the question of how much hydrogen remains from green ironmaking in the metal produced. We answer this question here by quantifying the amount of hydrogen in iron produced via two ...
The production method of hydrogen significantly influences its carbon footprint, presenting a dichotomy between green hydrogen (produced via electrolysis powered by renewable sources) and grey hydrogen (derived from steam methane reforming with natural gas). The British Energy Se...
Capital previously destined for oilfields has been, and will increasingly be, put into windmills, solar panels and green hydrogen production plants. Those investments will come not only in the form of assets, but also in retraining, retooling and reorganizing companies’ workforces. 2 Chapter 2...
Fracking is an inexpensive way to extract oil or natural gas that can't be reached through impermeable rock by conventional drilling. It requires injecting large volumes of water that can become contaminated and affect local soil and water supplies, however. It also releases large quantities of me...
