Techno-economic assessment of various hydrogen production methods - A review

Hydrogen is a clean fuel that could provide energy incentives and reduce environmental impacts, if production platform is carefully selected and optimized. In specific, techno-economic and sensitivity analysis of the existing hydrogen production platforms and processes is need for an hour to boost the future hydrogen economical aspects. This will have greater impact on future hydrogen production project designs and developing new approaches to reduce the overall production costs to make it as cheaper fuel. The sensitivity analysis of various hydrogen production process such as pyrolysis, gasification, steam reforming of natural gas, dark fermentation, photobiolysis, water electrolysis and renewable liquid reforming were reviewed to evaluate their merits and demerits along with cost-effectiveness. On economic view point, steam reforming of natural gas is efficient, low cost and best methods for hydrogen production. A future research is required to reduce energy input and trapping carbon dioxide emission using membrane models.

Automated summary

In order to advance the use of hydrogen as a clean fuel in the future, it is necessary to conduct techno-economic and sensitivity analyses of existing hydrogen production platforms and processes, and to develop new methods to reduce overall production costs. Steam reforming of natural gas is currently the most efficient and cost-effective method for hydrogen production.
