Vast quantities of gold hydrogen are produced in the Earth’s subsurface, via the serpentinization of iron-containing Peridotite rocks. Gold, white and orange hydrogen variations aim to harness this hydrogen. This…
…may unlock lower costs for turquoise hydrogen than blue hydrogen or green hydrogen. The disadvantage is that methane decomposition is endothermic, thus an exterior energy source is required. If this…
…comprising 85MTpa of grey hydrogen emitting 9 tons/ton of CO2 and 25MTpa of black hydrogen emitting 25 tons/ton of CO2. The purpose of this global hydrogen supply model is to…
…hydrogen and turquoise hydrogen as leading options. The costs of syngas and the costs of hydrogen from coal gasification depend on input variables. Capex costs are usually around $1,000/kWth of…
…– 10% hydrogen across a hydrogen value chain. (5) 3x higher hydrogen leakage rates are not an unjustified concern, because the radius of an H2 molecule is about 3x smaller than…
…hydrogen pipelines and chemical hydrogen carriers (e.g., ammonia). Midstream costs will be 2-10x higher than comparable gas value chains, while up to 50% of hydrogen’s embedded energy may be lost…
…efficiency. Our numbers are indexed at the electrolyser plant gate. On top of this, a full value chain requires hydrogen storage, hydrogen transport, and hydrogen use in a prime mover…
…methane input with a 6% hydrogen input, and the adiabatic flame temperature only reaches about 450ºC. The reason is that each mol of hydrogen only releases one-third of the combustion…
Our 18-page note models the full-cycle economics of a green hydrogen value chain to decarbonize trucks. In Europe, at $6/gallon diesel, hydrogen trucks will be 30% more expensive in the…
Blue hydrogen value chains are gaining momentum. Especially in the US. So this 16-page note contrasts steam-methane reforming (SMR) versus autothermal reforming (ATR). Each of these different hydrogen reformers has…
