Project summary description:
The global hydrogen storage market is projected to expand considerably in the coming decade. However, current options for hydrogen storage and delivery are inefficient and/or involve safety issues. Sodium borohydride (NaBH4) represents a strong alternative for storing and transporting hydrogen at scale, due to its high hydrogen content (10.8 per cent of its mass, wt%), effective hydrogen evolution controllability and easy handling. As a hydrogen carrier, NaBH4 can produce hydrogen via hydrolysis at room temperature without any energy input.
However, NaBH4 is currently expensive to produce, which prevents its wide applications. This is because the current production is based on a 70-year-old Brown-Schlesinger process, which is capital and energy-intensive, requires high temperatures and high pressures and generates large amounts of CO2.
This project will develop a blueprint for an industry-scale, cost-effective process to produce NaBH4 as a safe and efficient hydrogen carrier.
