Calling for a Revolution in Energy Use
Hydraulics are central to some of the most fundamental industries that build our world. However, while hydraulics is everywhere, they also require a lot of energy and most of that energy is simply wasted. McKinsey recently issued a report called Preparing for the Imminent Revolution in the Fluid Systems Industry, and they estimated that fluid pumps alone account for 15% of all energy used within the EU. But, as estimated by Oakridge National Laboratory, most hydraulic systems today only operate at 23% efficiency, resulting in the wastage of billions of kilowatt-hours every year.
The focus is now on for industry to change and become more sustainable. It is generally recognised that there is room for improvement in reducing waste and increasing efficiency in manufacturing, with some progress being made, but only of a few percent.
There is another way.
It is possible to design technology that increases hydraulic systems to 90% efficiency and therefore saving industry billions of CO2 a year.
How we are Redefining Energy Use
To bring the biggest revolution into hydraulics seen in a generation, we need to rethink how we use energy.
We must think differently, we have to approach a problem with a different question to create something new. At Domin, we are solving issues of inefficiencies by refining how we use energy.
When a forklift truck lifts an object up and then brings the object back down again, we currently use energy to lift the object up and bring it back down. However, we argue that this shouldn’t require any energy loss. The potential energy of what has been picked up and what is coming down hasn’t changed. It’s still zero. Rather than making each motion more efficient, if we design the system to use the same energy on the upward lift as the down, we have a lossless system and a more effective use of energy.
Our Total CO2 Savings, so Far...
Transforming Digital Motion
Through advanced engineering processes, additive manufacturing, and architectural design, we have developed a proportional valve that is digitally signalled. When using digital systems that deal with very small packets of energy, we can better manage the parts of the system that are inefficient.
We can control use to the minimum and therefore generate very little energy. We can then look at reclaiming, harvesting, energy, reusing that, and we can develop things that take a 10th of the energy of the things that exist today. This creates the possibility for motion control beyond anything that we can do today.
