EL PASO, TEXAS -- (MARKET WIRE) -- 12/12/07 -- Valcent Products Inc.
(OTCBB: VCTPF) -
The Vertigro Joint Venture has released initial test results from its high density bio mass (algae) field test bed plant located at its research and development facility in El Paso, Texas.

During a 90 day continual production test, algae was being harvested at an average of one gram (dry weight) per liter. This equates to algae bio mass production of 276 tons of algae per acre per year. Achieving the same biomass production rate with an algal species having 50% lipids (oil) content would therefore deliver approximately 33,000 gallons of algae oil per acre per year.

The primary focus of the 90-day continuous production test was
determining the robustness of the field test bed. Other secondary
tests were also conducted including using different ph levels, CO2
levels, fluid temperatures, nutrients, types of algae, and planned
system failures. It is important to note that the system has not been
optimized for production yields or the best selection of algae
species at this time.

The next phase of development will include increasing the number of
bio reactor units from 30 to 100 and then continuing a number of
production tests that may further increase production as well as
initiating various extraction tests. The results released today are
in keeping with data previously announced from the Joint Venture's
laboratory proof of concept test bed. Subsequently, the joint venture
intends to build out a one acre pilot plant with engineer design work
underway at this time.

As a comparative, food crop such as soy bean will typically produce
some 48 gallons oil per acre per year and palm will produce
approximately 630 gallons oil per acre per year. In addition, the
Vertigro Bio Reactor System is a closed loop continuous production
system that uses little water and may be built on non arable lands.

Glen Kertz and Dr. Aga Pinowska, who head the research and
development program, commented, "This is a major milestone for us as
we have demonstrated the robustness of the Bio Mass System with
satisfactory production results from a system that has not yet been
optimized for algae production, which will become part of the next
phase of testing." They also noted, "We have learned how to produce a
very large algal bio-mass under varying environmental and operating
conditions in our continuous process photo bioreactors. We believe
these initial results are amongst the best achieved to date, and we
are confident we can now increase the productivity."

"We are extremely pleased with the robustness and performance of the
Vertigro technology in sustainably producing commercial quantities of
algae biomass," states Doug Frater, Global Green Solutions CEO. "Over
the coming months we will further optimize the technology and
demonstrate economic algae production for biofuel feedstock
purposes."

The Vertigo system may be a solution to the renewable energy sector's
quest to create a clean, green process which uses mainly light, water
and air to create fuel. The Vertigro technology employs a proprietary
high-density vertical bio-reactor that produces fast growing algae
which may yield large volumes of high-grade algae oil. This oil can
be refined into a cost-effective, non-polluting diesel biofuel, jet
fuel and other applications. The algae derived fuel may be an energy
efficient replacement for fossil fuels and can be used in any diesel
powered vehicle or machinery. In addition, 90% by weight of the algae
is captured carbon dioxide, which is "sequestered" by this process
and so contributes significantly to the reduction of greenhouse
gasses.

Valcent: (OTCBB: VCPTF) (www.vacent.net), together with Global Green
Solutions Inc: (OTCBB: GGRN) (www.globalgreensolutions.com) are each
50% partners in the Vertigro Joint Venture that has developed a pilot
plant in El Paso which became operational in March 2007 and is the
primary research and development site for the Vertigro technology.
Valcent's primary responsibility is research and initial development
with Global Green's responsibilities including final engineering and
commercialization of Vertigro.
