Are electro-hydraulic hybrid systems the future of hydraulics?

Future opportunities and research directions are prospected. With the growing urgency of the energy crisis, hybrid power offers an advanced means of energy optimization, where electro-hydraulic hybrid systems, such as electro-hydrostatic actuators (EHAs), represent a novel opportunity for hydraulics.

Is pumped hydroelectric storage a good alternative to other storage systems?

The graph shows that pumped hydroelectric storage exceeds other storage systems in terms of energy and power density. This demonstrates its potential as a strong and efficient solution for storing an excess renewable energy, allowing for a consistent supply of clean electricity to meet grid demands.

How much energy can a hydraulic actuation system recover?

In assistive phases, the hydraulic system can recover up to 81.8% of the actuator energy. The comparison between open-circuit and closed-circuit structures shows the advantages of the former in terms of energy efficiency. The proposed solution is suitable for electrified hydraulic actuation systems, in both industrial and mobile applications.

What is an electro-hydraulic hybrid system (EHA)?

As an electro-hydraulic hybrid system, the EHA is capable of recovering energy by batteries and hydraulic accumulators during assistive working modes [9, 10], which is a great advantage compared to DC systems.
