Ecoduna productions GmbH

ecoduna is the European

innovation leader in algal

photo bioreactors,

ecoduna has been several

fold awarded for its

outstanding technology.

The company was funded

2008 by Franz Emminger

and Martin Mohr after a 4

years period of R&D

development, it was

changed into an Austrian

limited company (GmbH) in

2010

WHAT ELSE?


m

The origin of crude oil is from marine

plant life up to 3 billion years ago.

Today, algae are considered to be one

of the most promising renewable raw

materials for many purposes.

ALGAE AS A RESOURCE

Is production of renewable oil from algae in reach?


m

Renewable energy source

Algae versus Oilseeds

No competition with food production

10 to 20 times less land demand for the same amount of biomass

Far less water demand then agriculture

Competitive price range is in reach (economy of scale)

Algae oil costs €2,5 to €4 /litre today


m

Renewable energy source

Algae versus Photovoltaic

Photosynthesis is limited to a max. efficiency of 11% of light utilisation today

Light shifting in cultivation systems will give the efficiency a substantial raise in future

No rare earth elements are needed

A energy carrier/fuel with high energy density is produced; it can be stored easily and utilised on demand

The ecoduna technology avoids the disadvantages of other processes in the utilization of light.

Light from the sun is diluted from 80.000 down to 1.500 – 2.500 lux irradiation, the optimum for algae growth.

80,000lux / 2,500lux = 32

By diluting the sunlight by the factor 32, ecoduna is obtaining the optimal light-density for algae growth.

PHOTOSYNTHESIS RATE TO LIGHT INTENSITY


m

TROPHOGENIC ZONE; PHOTO ACTIVE VOLUME

To understand the significance of photo-bio-reactors, the most

important terms are photo active volume and trophogenic zone

Only the trophogenic zone matters, all the rest volume only

expands costs


m

TROPHOGENIC ZONE; PHOTO ACTIVE VOLUME

Ponds must have a certain depth to puffer temperature, pipes are of a

certain diameter because of material and assembling costs.

Both systemic approaches neglect the ideal form for light integration

Continuity - Tricky normal distribution

Chlorella 32% Oil content?

The expected yield in

discontinues cultivation will

be according to the

probability density function

and therefor only a fraction

of the expected max. yield.

A continuous production can account for all the phases of algae, supplies the required conditions and ensures a yield, close to the max. capacity

Status Quo

ecoduna has moved in record time from first prototypes to industrial scale. .

A industrial size production unit has been sold to GMB Vattenfall, the largest thermal energy provider in Europe, to reduce CO² from a coal power station, starting operation in July 2011


m

CIP

The European Union has granted ecoduna a substantial fund under the “Competitiveness and Innovation Framework Programme” (CIP).

ecoduna will build and run the second largest photo bioreactor unit for microalgae in in the west, from September 2011 on in Austria
