Abstract
To help facilitate a global transition to low-carbon emissions energy sources, hydrogen injection into BC's Coastal Gaslink pipeline, replacing a portion of the existing natural gas, is proposed. The hydrogen and natural gas would be processed at the destination plant in Kitimat for export. The economics of this including operational and infrastructure costs are considered to study the economic benefit to replacing some natural gas with hydrogen. A rough process to separate natural gas from hydrogen at the destination plant is outlined. The energy requirements to liquefy hydrogen are estimated based on the conditions of the processing plant. This energy requirement is compared to those of other proposed hydrogen liquefaction plants to estimate the specific liquefaction cost for hydrogen at the Kitimat plant.
Ultimately, the results show that hydrogen injection would be profitable, increasing daily earnings by $1.1 million CAD with 5% hydrogen injection (by volume).
