              Sapphire Energy and Linde Group Expand Partnership

Companies Partner to Commercialize Hydrothermal Treatment Technology Used to
Upgrade Algae into Crude Oil

PR Newswire

SAN DIEGO and MUNICH, July 16, 2013

SAN DIEGO and MUNICH, July 16, 2013 /PRNewswire/ --Sapphire Energy, Inc., one
of the world leaders in algae-based Green Crude oil production, and the
technology company The Linde Group today announced they will expand their
partnership to commercialize a new industrial scale conversion technology
needed to upgrade algae biomass into crude oil. Together, the companies will
refine the hydrothermal treatment process developed and operated today by
Sapphire Energy at pilot-scale. In addition, they will jointly license and
market the technology into an expanded list of industries, including algae,
municipal solid waste, and farm waste, in order to upgrade other biomass
sources into energy. The agreement spans a minimum of five years through the
development of Sapphire Energy's first commercial scale, algae-to-energy
production facility.

"Sapphire Energy is very pleased to build upon its already successful
strategic partnership with Linde to build a commercial oil upgrading process
designed to increase yield and lower the cost of crude oil production," said
Cynthia 'CJ' Warner, CEO and chairman of Sapphire Energy. "Large energy
projects like we are building require very significant partnerships to fund
the development of new technologies and make available engineering resources
needed to bring these projects on line at commercial scale. We think Linde is
a perfect partner to help Sapphire achieve this goal."

"We have been working with Sapphire Energy for two years to develop a
cost-efficient CO[2] delivery system for commercial algae production. We have
become confident with the company's expertise and its capability to produce a
low carbon and economic energy source from algae. After the positive
experience gained, we decided to intensify our cooperation with Sapphire,"
said Professor Dr. Aldo Belloni, Member of the Executive Board of Linde AG.
"Based upon our profound engineering expertise, we will contribute to further
develop and scale up Sapphire's algae-to-crude-oil technology."

This growing partnership builds upon Linde's and Sapphire Energy's agreement
to develop a low cost, CO[2] management system for open pond, algae-to-fuel
production, which was previously announced in May 2011. Linde, the leading
merchant CO[2] supplier in the U.S., also became the exclusive supplier of
CO[2] for Sapphire Energy's commercial demonstration, algae-to-energy facility
in Columbus, New Mexico. Today, this Green Crude Farm is operating year-round
and producing barrels of crude oil daily.

About Sapphire Energy

San Diego-based Sapphire Energy is pioneering an entirely new industry – Green
Crude production – with the potential to profoundly change America's energy
and petrochemical landscape for the better. Sapphire's products and processes
in this category differ significantly from other forms of biofuel because they
are made solely from photosynthetic microorganisms (algae and cyanobacteria),
using sunlight and CO[2] as their feedstock; are not dependent on food crops
or valuable farmland; do not use potable water; do not result in biodiesel or
ethanol; enhance and replace petroleum-based products; are compatible with
existing infrastructure; and are low carbon, renewable and scalable. Sapphire
has an R&D facility in Las Cruces, New Mexico, and is currently operating the
first Integrated Algal BioRefinery in Columbus, New Mexico, continuously since
May 1, 2012. For more information, visit www.sapphireenergy.com or
