TRANSCRIPT

Green Carbon in a sustainable way for developing countries

Dr. Willie Smits, Masarang Foundation Smart energy for a sustainable future Session on “Future Energy Supply” BASF, Ludwigshafen, March 10th-2015

Vinod Khosla

"What is needed is something that replaces base-load coal technology. Unless technology does that, it's not competitive.”

"Today's unimaginable is tomorrow's conventional wisdom."

Today’s Presentation

• Assessing the true potential of biomass based energy with special focus on sugar palms

• Looking at sustainability issues in triple P terms for reforestation in developing nations

• Practical example of a large scale commercial operation based upon these approaches

Biomass Based Energy

• The 1% photosynthesis efficiency theory • The photosynthesis process is influenced by:

– Light intensity – CO2 concentration – Temperature

• Other factors determining plant productivity: – Method of photosynthesis (eg. C3 vs C4) – Water and nutrient availability – Pests and diseases

Zone of Maximum Productivity (Most Solar Radiation/Rainfall)

and zone with most available land and most people in need

Sugar Palm Biomass Based Energy

• The 1% photosynthesis efficiency theory • The photosynthesis process is influenced by:

– Light intensity – CO2 concentration – Temperature

Other factors determining plant productivity: Method of photosynthesis (eg. C3 vs C4) Water and nutrient availability Pests and diseases LAI (Leaf Area Index) Harvest Index Energy conversion efficiency

How is the 1% efficiency calculated?

Wh=S* εi* εc*η

in which Wh = Harvested Yield

S = Total solar energy

εi = Interception efficiency

εc = Conversion efficiency

η = Partitioning efficiency (Harvest Index)

The case of the Sugar Palm

εi = Interception efficiency

interception efficiency depends upon the speed of canopy closure, plant canopy size and plant architecture.

• Once a forest canopy is present, a fully developed photosynthetic apparatus is always present (no more growing investment phase like with agricultural crops)

• With a high LAI (>6.5 for sugar palm vs. 3.0 for most trees and crops) and more efficient light capture, combined with special leaf arrangement εi is very high

Sugar palm forest

Many years of field experiments

The case of the Sugar Palm

εi = Interception efficiency

interception efficiency depends upon the speed of canopy closure, plant canopy size and architecture.

εc = Conversion efficiency

Conversion efficiency depends upon the method of photosynthesis (C3/C4) and respiration rates

• Sugar palms have C4 photosynthesis • Respiration is extremely low due to absence of

maintenance growth after start of production

Combining the positive aspects of trees and energy crops like corn

Once fully grown & flowering all energy goes to to the fruit

For new harvestable fruit new leaves need to form

Hapaxanthic male inflorescences

The case of the Sugar Palm

εi = Interception efficiency interception efficiency depends upon the speed of canopy closure, plant canopy size and architecture.

εc = Conversion efficiency

Conversion efficiency depends upon the method of photosynthesis (C3/C4) and respiration rates

The harvest index indicates how much of the plant material can be converted to utilizable energy

η = Partitioning efficiency (Harvest Index)

For the best corn this is about 55% of the above ground biomass, so η being 0.55, with little room for improvement.

η = Partitioning efficiency (Harvest Index)

• A sugar palm can produce many times the harvestable biomass compared to its own dry weight infrastructure

200 Tapping Days

1920 Total Sugar (kg)

160 Leaf biomass

280 Stem biomass

105 Root biomass

135 Fruit biomass

680 Total Mass (kg)

Note: For an individual tree the tapping takes place over almost three years and with a life span of 10 years η is only slightly higher but as forest much more!

In addition

• From sugar palms we do not harvest organs and the output is sucrose, a very efficient energy carrier

• Sugar palms have very deep roots and need little water and can maintain photosynthesis where other trees experience a midday photosynthetic depression period

No removal of organs! Just tapping Water & Sugar

Sugar Palms add nutrients

to soil

All other biofuel crops remove nutrients

so always need fertilizer

70 Trees/ha

Daily production of sugary juice 13 Liters/day/tree

Sugar concentration in juice 11 Percent Sugar production per hectare per year

(Calculation based upon data compiled from various studies by dr.ir. Willie Smits)

Six independent assessments done November 2011

Oil Palm vs. Sugar Palm (Elaeis guineensis)

• Leading to carbon emissions • Leading to deforestation • 5 tons of biodiesel/ha/yr • Monoculture • Needs fertilizers/pesticides • Soil depletion • Watershed pollution • Rivers disrupted • Coral reefs affected • Few and poor jobs (0.11/ha/yr) • Mechanization under way • Causes many local conflicts

(Arenga pinnata)

• Carbon sequestration • Protecting forests • 19 tons of ethanol/ha/yr • Mixed forest/Biodiversity • No fertilizers/pesticides • Soil improvement • Improved water supplies • Rivers flow regular • No downstream problems • Many (2.14) all year round jobs • Non mechanizable • Brings communities together

Sugar palms need a mixed forest

All sugar palms from same mother tree and same age Only those closer to trees growing healthy and better

Palm that soon will produce

Producing Palm

Tapping is manual and labor intensive Palms have to be tapped twice a day.

Each day 1 mm is sliced off

After 40 minutes the 10-17% sugary juice reaches maximum dripping speed

After 12 hours the speed gets less

Other Sugar Palm Products: • Fruits • Fibers • Medicines • Sago (starch) • Palm Heart • Honey • Fuel wood • Timber • Scent material • Orchid media • Packing material • Etc., etc.

8 year old mixed Sugar Palm Forests protecting the steep Masarang slopes

The practical application

• The company manages almost half a million acres of severely degraded forest in East Kalimantan.

• After the closure of the wood industry many people became jobless, causing a lot of land pressure.

• In this area the company is establishing a giant zero waste system to produce fossil fuel replacements and various other sustainable products.

• All of this while creating sustainable jobs, food security, clean water provision and biodiversity protection

What about combining restoring forests, plus additional permanent carbon storage in soil and improved growth of the forest, with ethanol as well as fossil fuel coal replacements and production of drop in jet fuel from waste within 2 years from start…?
