In the field of construction machinery, hydrogen fuel and lithium batteries as two kinds of clean energy, both have significant advantages and limitations, the future competition will be around technological breakthroughs, infrastructure and application scenarios.

In terms of technical characteristics, the energy density of hydrogen fuel is relatively high, so the battery life is longer, suitable for heavy duty continuous operation, lithium battery energy density is low, the need for frequent charging and change;  In terms of charging efficiency, hydrogen fuel cell hydrogenation only takes 3 to 5 minutes, similar to our diesel, while lithium battery needs to be charged for 1 to 2 hours;  In terms of low temperature performance, hydrogen fuel cells are less affected by temperature and can run stably at minus 30 degrees Celsius.  The capacity of lithium batteries will decay with the decrease of temperature, and thermal management system is needed to keep heat.

In terms of scene adaptation, in the short term, lithium batteries will remain the mainstream choice for electric excavators with maturity and economy.  However, with the improvement of the hydrogen energy industry chain, hydrogen fuel cells will occupy an advantage in the field of large-scale and long-life construction machinery.  In the future, the two technologies may complement and coexist in different application scenarios: lithium batteries are more suitable for small and medium-sized excavators in urban construction sites and short-time operation scenarios.  The high energy density and fast filling advantages of hydrogen fuel cells are more obvious, and they are more suitable for large mining excavators.
