Analysis of hydrogen production costs in Steam-Methane

The production of low-carbon hydrogen can play a key role in enabling decarbonization, primarily due to its clean-burning, high energy capacity, versatility, and efficiency (Katebah et al., 2022).Two main options are being explored for producing hydrogen with a low carbon intensity: fossil fuel ''blue hydrogen'' production from natural gas, and electrolysis driven

Prospects for Direct Air Carbon Capture and Storage: Costs,

Abstract. Direct air carbon capture and storage (DACCS) has the potential to contribute to meeting long-term climate goals. An ambitious deployment scenario shows DACCS growing rapidly to remove about 400 MtCO 2 per annum (p.a.) by 2050, the equivalent of a little over 1% of 2022 emissions from the energy and industry sectors, and reaching one Gigatonne

Executive summary – Direct Air Capture 2022 – Analysis

Capturing CO 2 from the air is the most expensive application of carbon capture. The CO 2 in the atmosphere is much more dilute than in, for example, flue gas from a power station or a cement plant. This contributes to DAC''s higher energy needs and costs relative to these applications. But DAC also plays a different role in net zero pathways, including as a CDR solution.
