The global energy landscape is experiencing a significant shift towards Green Hydrogen
as a sustainable and clean energy paradigm. This research highlights Sri Lanka's
potential to invest in this new venture due to its abundant renewable energy capacity.
This study evaluated the most suitable hydrogen producing electrolyzer for Sri Lanka and
Green Hydrogen production capacity in Sri Lanka against available renewable energy.
Further, studies about favourable hydrogen utilization pathways in Sri Lanka. A literature
survey was conducted to obtain data related to the AWE, AEM, PEM, and SOE electrolyzer
technologies and they were evaluated against capital expenditure, operating expenditure,
performance, and technological maturity in selecting an electrolyzer for Sri Lanka.
Projected renewable energy capacity for 2030 with peak demand and average demand
was considered in the calculation of producible Green Hydrogen amount. For utilization
pathways in Sri Lanka, the intensiveness of infrastructure requirement, costeffectiveness,
policy and regulations, environmental impact, and safety were analyzed for
selected utilization opportunities which included grid balancing, fertilizer production, and
fuel blend. Implementing an Alkaline Water Electrolyzer (AWE) was identified as the
optimal choice for Green Hydrogen production technology in Sri Lanka and has the
capacity to produce 13,500 MWh of Green Hydrogen. It was concluded that produced
Green Hydrogen can be utilized as energy storage to mitigate grid imbalance or as a
feedstock for fertilizer production. Although use of this technology holds tremendous
potential for supporting Sri Lanka's energy needs, an in-depth study should be done
towards utilization pathways. |
