This study presents an assessment of all-in cost considerations for deploying hydrogen and carbon capture technologies in power generation. It incorporates data from recent EPRI cost and performance studies, industry reports, techno-economic analysis tools, and subject matter expert input into a unified framework to capture the broad spectrum of costs. Hydrogen pathways are evaluated with a focus on electrolytic production (alkaline and PEM) and steam methane reforming with carbon capture, alongside infrastructure requirements such as pipeline transport, bulk underground storage, on-site gaseous and liquid storage, and combustion turbine. For carbon capture, the analysis includes the capture system, pipeline transport, and long-term storage in saline formations.
The study reveals that costs for these emerging technologies span a wide range across several cost categories, from production and storage to transport and combustion, and from capture equipment to injection wells and multi-decade monitoring plans. Relying solely on traditional power plant CAPEX and OPEX categories risks underrepresenting the total cost of these technologies. For utilities pursuing decarbonization, this cost framework supports more comprehensive planning by enabling integrated resource planning processes to evaluate hydrogen and carbon capture technologies on a consistent, comparable basis with conventional generation technologies.
