As a subject matter expert in the field of renewable energy and chemical engineering, I have a deep understanding of the processes involved in hydrogen production. The cost of producing hydrogen is a complex topic that depends on various factors including the production method, scale of production, and the current market conditions. Let's delve into the details.
Hydrogen can be produced through several methods, including steam methane reforming (SMR), electrolysis, and biomass gasification, among others. Each method has its own cost structure and efficiency.
Steam Methane Reforming (SMR) is the most common method for hydrogen production, accounting for about 76% of global hydrogen production. This process involves reacting methane with steam at high temperatures to produce hydrogen and carbon monoxide, which can then be further processed to separate hydrogen. The cost of SMR is influenced by the price of natural gas, which is the primary feedstock. Additionally, capital and operational costs, including the cost of equipment, energy, and labor, play a significant role.
Electrolysis is a method that uses electricity to split water into hydrogen and oxygen. There are different types of electrolysis, including alkaline, polymer electrolyte membrane (PEM), and solid oxide electrolysis. The cost of electrolysis is highly dependent on the cost of electricity. Renewable energy sources can significantly reduce the cost and carbon footprint of hydrogen produced through electrolysis. The efficiency and cost of the electrolyzer itself, as well as the purity of the hydrogen produced, are also important factors.
Biomass Gasification involves converting biomass into a gas mixture through high-temperature reactions in the presence of limited oxygen. This gas mixture can then be processed to extract hydrogen. The cost here is influenced by the availability and cost of biomass feedstock, as well as the efficiency of the gasification and subsequent hydrogen purification processes.
The reference to "1 kilogram is 1 gallon of gasoline equivalent (gge)" is an important point as it provides a basis for comparing the energy content of hydrogen to that of gasoline. This comparison is crucial when considering the economic viability of hydrogen as an alternative fuel.
The cost figures mentioned, "$0.0015/gallon + $0.987/kg (gge) Refining Costs = $0.9885 = $1.00/kg (gge) using Atmospheric Electrolyses," suggest that the cost of producing hydrogen through atmospheric electrolysis is approximately $1 per kilogram of gasoline equivalent. However, these figures need to be taken with caution as they can vary greatly based on the specific conditions of production, including the source of electricity, the efficiency of the electrolyzer, and any subsidies or incentives that may be available.
It's also worth noting that the efficiency of hydrogen production can be significantly improved with technological advancements and economies of scale. As the demand for hydrogen as a clean energy carrier grows, we can expect costs to decrease due to increased investment in research and development, as well as the expansion of production facilities.
In conclusion, the cost of producing hydrogen is multifaceted and influenced by a variety of factors. While the figures provided offer a glimpse into the current costs, it's essential to consider the broader context of production methods, feedstock prices, and technological advancements when assessing the true cost of hydrogen production.

Hydrogen is measured by the kilogram. 1 kilogram is 1 gallon of gasoline equivalent (gge). 2. $0.0015/gallon + $0.987/kg (gge) Refining Costs = $0.9885 = $1.00/kg (gge) using Atmospheric Electrolyses. -- 50 gallons per drum = 6.66 --barrels of H2-- per 1000 gallons of water.
