Fluid power systems consume a significant portion of our nation’s energy. Existing technologies and
best practices have been shown to reduce energy use in fluid power systems, in some cases by up to
30% or more.Through the Technology Roadmap for the Fluid Power Industry, the industry is identifying and addressing key research challenges that will continue to meet the needs of its diverse customer base.
Fluid power has an active industry/academic coalition that focuses on these key research challenges. Recent breakthroughs have been made in increasing energy efficiency, increasing energy storage capabilities, and reducing the size of fluid power components and systems.Future directions of fluid power research will additionally focus on improving its reliability, building “smart” components and systems, and reducing its environmental impact.
A new effort to address the specific manufacturing needs of the fluid power industry has begun. This effort will seek to leverage several key manufacturing technologies to improve the production and
performance of fluid power components and systems. Executive Summary cont.

Education & Training
Fluid power and the industries it serves depend on a highly-educated workforce. Investments in new fluid
power education and training resources are occurring, and more 2-year and 4-year colleges are teaching fluid power. NFPA maintains a network of these colleges, and their regional distribution across the country is increasing.Number of 2-year and 4-year colleges in the NFPA

Energy and Efficiency
Fluid power systems consume a significant portion of our nation’s energy, and well-designed and well-
maintained fluid power systems can be very energy efficient. Unfortunately, many working fluid power systems are not well designed nor well maintained. Many technologies and best practices exist to maximize the energy efficiency of fluid power systems, including:Several companies perform audits to identify and troubleshoot weaknesses in working fluid power systems. Data
provided by one these companies indicate that when these technologies and best practices are implemented, average energy savings are 31%, and the cost of implementation is recouped within 4-5 months.Hydraulic systems:Eliminating parasitic lossesEffective flow controlSmart use of accumulators

NFPA’s Technology Roadmap for the Fluid Power Industry identifies the key research challenges that the
industry is addressing for fluid power to continue meeting the needs of its diverse customer base.Customer Drivers
Research ChallengesCustomer drivers are the business or technology objectives of fluid power customers. They help them serve the needs of their own customers, and are not necessarily connected to their use of fluid power.
Research challenges are the broad areas of attention that must be addressed if fluid power is to meet or better meet the customer
needs described by the drivers.Increasing the energy efficiency of fluid power components and systems

Research & Development
The Center for Compact and Efficient Fluid Power (CCEFP) is a network of fluid power research laboratories,
academic faculty and graduate students at several U.S. universities. The CCEFP works with the fluid power industry to tackle the research challenges identified in NFPA’s Technology Roadmap for the fluid power Industry. Its research successes include:
High Efficiency ExcavatorThe use of individual pump displacement control to directly command hydraulic actuators has demonstrated 40% fuel savings on an excavator. Efforts are currently underway to
incorporate hybridization into the system for even greater fuel savings.
Strain Energy Accumulator
Free Piston Engine/Pump
Precise piston motion control is
necessary for reliable operation of a
free piston engine pump that can
directly convert liquid fuel combustion
into hydraulic power. The demonstration of this technology merges the engine
and pump into one compact assembly.
Increasing Energy Efficiency
Improving Energy Storage
Reducing the Size of

Current accumulators use either
compressed gas or springs to store energy.
Conversely the CCEFP carbon nanotube
elastomeric accumulator safely stores
energy as strain. Energy savings greater
than 25% have been demonstrated
over existing pneumatic systems. Slide15
A second technology roadmap—this one focused on improvements in how fluid power components are
manufactured—was published in the past year. It reveals several cross-cutting themes that are specific to the fluid power industry, including the need for:High precision coupled with multiple product configurations and small orders sizes
