When will electrolytic hydrogen become competitive

摘要: Abstract The potential role of electrolytic hydrogen in Canada is assessed for the period 1980–2025 large-scale uses only. For such uses, will be derived from natural gas, coal or electrolysis water during interest. Cost estimates are obtained a parametric equation. Values Canada's unique unipolar technologies compared with those bipolar electrolysers. Both by-products production, namely heavy and oxygen, evaluated. projections gas coal, based on simple but realistic assumptions. All cost data given constant 1980 Canadian dollars. Electrolytic hydrogen, non-fossil primary energy sources, also considered as another “liquid fuel option” along alcohols. market general reference higher use scenario both traditional hydrogen. From assessments demand estimated question. Results show that large by year 2025.
