GH2 Storage Done Right: Without Sacrificing Sustainability

The biggest #sustainability challenge in #GH2 storage lies in 𝐛𝐚𝐥𝐚𝐧𝐜𝐢𝐧𝐠 𝐢𝐦𝐦𝐞𝐝𝐢𝐚𝐭𝐞 𝐚𝐯𝐚𝐢𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲 𝐰𝐢𝐭𝐡 𝐥𝐨𝐧𝐠-𝐭𝐞𝐫𝐦 𝐜𝐨𝐬𝐭-𝐞𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞𝐧𝐞𝐬𝐬 𝐚𝐧𝐝 𝐫𝐞𝐠𝐮𝐥𝐚𝐭𝐨𝐫𝐲 𝐜𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞 (e.g. EU Seveso-III Directive, Permitting, Infrastructure standard adherence, EU’s Hydrogen & Gas Decarbonisation Package and RED III).

Biyat Energy & Environment Ltd can help organisations navigate these challenges by identifying the most suitable storage and delivery solutions tailored to their specific needs, ensuring efficient and sustainable hydrogen supply for their operations.

𝐌𝐢𝐝-𝐫𝐚𝐧𝐠𝐞 𝐪𝐮𝐚𝐧𝐭𝐢𝐭𝐲 𝐬𝐭𝐨𝐫𝐚𝐠𝐞 solutions for #greenhydrogen are crucial for ensuring a stable and reliable supply across the production, transport, and end-use phases. With onsite storage providing immediate availability and reduced transportation costs, the disadvantage is the space requirement and maintenance.

Pipeline delivery is cost-effective over long distances and supports centralised production but demands high initial investment and regulatory challenges. Three pivotal projects in the space are the 𝐖𝐚𝐬𝐬𝐞𝐫𝐬𝐭𝐨𝐟𝐟-𝐊𝐞𝐫𝐧𝐧𝐞𝐭𝐳, 𝐒𝐨𝐮𝐭𝐇2 𝐂𝐨𝐫𝐫𝐢𝐝𝐨𝐫 and 𝐇2𝐌𝐞𝐝 networks.

Let's take a look at some of the storage options: -

𝐒𝐨𝐥𝐢𝐝-𝐒𝐭𝐚𝐭𝐞 𝐒𝐭𝐨𝐫𝐚𝐠𝐞 (𝐒𝐦𝐚𝐥𝐥 𝐪𝐮𝐚𝐧𝐭𝐢𝐭𝐲)
Materials like metal hydrides or chemical compounds can absorb and release hydrogen, providing a safer and more compact storage option. However, these materials often have lower storage capacities and require specific conditions for efficient hydrogen release.

𝐂𝐨𝐦𝐩𝐫𝐞𝐬𝐬𝐞𝐝 𝐇𝐲𝐝𝐫𝐨𝐠𝐞𝐧 (𝐒𝐦𝐚𝐥𝐥 𝐭𝐨 𝐌𝐞𝐝𝐢𝐮𝐦)
Storing hydrogen as a compressed gas in high-pressure tanks is a common method. However, it requires robust materials to handle the high pressures and poses safety risks.

𝐎𝐫𝐠𝐚𝐧𝐢𝐜 𝐂𝐚𝐫𝐫𝐢𝐞𝐫𝐬 (𝐞.𝐠., 𝐀𝐦𝐦𝐨𝐧𝐢𝐚) (𝐌𝐞𝐝𝐢𝐮𝐦)
Ammonia can be used as a hydrogen carrier, offering easier storage and transport. However, it requires conversion back to hydrogen, which involves additional energy and infrastructure.

𝐋𝐢𝐪𝐮𝐢𝐝 𝐇𝐲𝐝𝐫𝐨𝐠𝐞𝐧 (𝐌𝐞𝐝𝐢𝐮𝐦 𝐭𝐨 𝐋𝐚𝐫𝐠𝐞)
Liquefying hydrogen by cooling it to very low temperatures allows for higher storage density but is energy-intensive and requires cryogenic storage systems.

𝐔𝐧𝐝𝐞𝐫𝐠𝐫𝐨𝐮𝐧𝐝 𝐒𝐭𝐨𝐫𝐚𝐠𝐞 (𝐋𝐚𝐫𝐠𝐞)
UG vertical storage in salt caverns, depleted gas reservoirs, or saline aquifers is a promising solution for large-scale hydrogen storage. This method is considered safer and more cost-effective compared to above-ground storage. However, it requires suitable geological formations and significant initial investment. Vallourec also offer innovative modular UG vertical systems for medium range storage. https://lnkd.in/dbvSDD9P
