Osmotic Power Play: Energy Recovery Teams with GS Engineering & Construction Corp to Develop Highly Available Renewable Energy Source
(Thomson Reuters ONE) -
South Korean Industrial Conglomerate Adopts Desalination Leader's Proven PX
Pressure Exchanger Technology to Advance New Category of Clean Energy
SAN LEANDRO, Calif., October 15, 2013 - Energy Recovery Inc. (NASDAQ: ERII), the
leader in capturing reusable energy from industrial fluid flows and pressures
cycles, today announced that it has signed a mutual cooperation agreement with
Seoul-based global company GS Engineering & Construction Corporation (GS E&C
Corp) which is a part of Korean conglomerate GS Group, to significantly
advance osmotic power generation using Energy Recovery's state-of-the-art PX
Pressure Exchanger® technology. A pilot program is already underway and it is
anticipated that a unit will be operational in 2014 at GS E&C Corp R&D center in
Korea.
The revolutionary process of Pressure Retarded Osmosis (PRO) is created by
mixing of seawater and freshwater and the resulting osmotic power serves as both
a renewable and consistent source of electricity. While still the in the early
stages, the best estimates of global production potential of osmotic power
exceed 1,600 terawatt hours, or the equivalent of half of Europe's entire energy
demand.
Initially developed for seawater reverse osmosis (SWRO) desalination, Energy
Recovery's PX® devices have shown tremendous potential and interest across
multiple industries due to their adaptability, reliability and efficiency.
How Energy Recovery's PX Pressure Exchangers® Work
Energy Recovery's PX devices are currently deployed at SWRO desalination plants
all over the world. By recycling the energy typically wasted as part of the
reject stream, the PX devices-which operate at 98 percent efficiency-reduce
energy use by up to 60 percent, helping to make desalination an affordable
solution to global water scarcity. Energy Recovery's devices function on a
similar principle in osmotic power processes. You can watch a video of that
process here: How the PX Pressure Exchanger works.
How Osmotic Power Works
For many years the idea of PRO or osmotic power was 'pie in the sky' scientific
theory and not seen as a viable energy solution.[1] Today, the fields of
chemical engineering and science are looking at this renewable energy source as
a major solution to the world's water and energy scarcity problems.[2] Osmotic
power process can convert the pressure differential between two water streams
into hydraulic pressure that can be used to drive a turbine that produces
electrical energy. The PX devices work in unison with the turbines to cost-
effectively enable stable, reliable, environmentally friendly energy production
anywhere freshwater and saltwater are available.

The advantages of osmotic power are numerous:
* Generates clean power with no harmful emissions
* Seawater is abundant and readily available
* Solution is scalable and applicable worldwide
* More reliable than other power sources (i.e. Wind and solar) because the
power generated is base loaded
Proven Partners
GS E&C Corp is one of the main Korean multinational firms investing heavily in
R&D in the global water and renewable energy markets. In 2011 GS E&C Corp
acquired Spanish desalination facility maker, Inima, one of the world's top ten
reverse osmosis (RO) desalination specialists, for $US 287M. Through this
acquisition, GS E&C Corp aims to expand its RO desalination business operations.
Soon thereafter, GS E&C Corp was issued a multimillion-dollar grant from the
South Korean government to expand their research and development program to
design a pilot plant for a Pressure Retarded Osmosis (PRO) application. For GS
E&C Corp, entering into a joint R&D effort with Energy Recovery was a logical
extension and next step given its market leadership in reverse osmosis
desalination.
"We're thrilled to partner with Energy Recovery on osmotic power technology that
promises to bring about innovative and sustainable change," said Mr. Jeong Woo
Seo, CTO of GS E&C. "We chose the PX based on the value and proven reliability
and performance that it has provided to us and dozens of other engineering firms
worldwide for over two decades."
"GS Engineering & Construction Corp is a visionary company, on the horizon of
the next big thing. We have been looking forward to developing this technology
with a strategic technology partner to make osmotic power a reality across the
world," said Tom Rooney, CEO of Energy Recovery. "It's ideal to collaborate with
a proven engineering market leader such as GS Engineering & Construction Corp
and thrilling to adapt our core technology for new sources of renewable energy."
