Publication: Fast Filling of CHG2 Tanks

To enable wider adoption of 𝐡𝐲𝐝𝐫𝐨𝐠𝐞𝐧 𝐦𝐨𝐛𝐢𝐥𝐢𝐭𝐲, we need 𝐟𝐚𝐬𝐭𝐞𝐫 𝐫𝐞𝐟𝐮𝐞𝐥𝐢𝐧𝐠 without compromising 𝐬𝐚𝐟𝐞𝐭𝐲. During rapid filling 𝐜𝐨𝐦𝐩𝐫𝐞𝐬𝐬𝐞𝐝 𝐠𝐚𝐬𝐞𝐨𝐮𝐬 𝐡𝐲𝐝𝐫𝐨𝐠𝐞𝐧 (𝐂𝐆𝐇₂) 𝐭𝐚𝐧𝐤𝐬, in-tank temperatures can become highly 𝐢𝐧𝐡𝐨𝐦𝐨𝐠𝐞𝐧𝐞𝐨𝐮𝐬, and our experiments with Type III and IV tanks (60–320 L) show that the 𝐨𝐧-𝐭𝐚𝐧𝐤 𝐯𝐚𝐥𝐯𝐞 𝐬𝐞𝐧𝐬𝐨𝐫 can significantly 𝐮𝐧𝐝𝐞𝐫𝐞𝐬𝐭𝐢𝐦𝐚𝐭𝐞 the actual average tank temperature. The position of 𝐡𝐨𝐭 𝐬𝐩𝐨𝐭𝐬 depends on tank size, geometry, and filling conditions, making 𝐬𝐞𝐧𝐬𝐨𝐫 𝐩𝐥𝐚𝐜𝐞𝐦𝐞𝐧𝐭 critical for reliable temperature measurement. Accurate temperature data are not only essential for 𝐬𝐚𝐟𝐞 𝐫𝐞𝐟𝐮𝐞𝐥𝐢𝐧𝐠 𝐩𝐫𝐨𝐭𝐨𝐜𝐨𝐥𝐬 (e.g. SAE J2601–5), but also for developing and validating 𝐦𝐨𝐝𝐞𝐥-𝐛𝐚𝐬𝐞𝐝 𝐩𝐫𝐞𝐝𝐢𝐜𝐭𝐢𝐨𝐧𝐬 of tank temperature during fast fills.
