GKG Energy

Analysis shows that there is enough land on Earth to grow food and fuel as well, if the crop has high productivity (yeld) – for use in liquid biofuels and for direct combustion. Direct combustion of biomass allows 24h electricity generation – Solar energy only when the sun shines and Wind energy only when the wind blows…

GIANT KING GRASS

ü  Non-food feedstock for low carbon liquid biofuels for transportation including cellulosic ethanol

ü  Low carbon biomass replacement for coal in electric power plants.

ü  Feedstock  for bio-methane production

NONFOOD BIOFUELS

Liquid Biofuels for transportation

ü  Gasoline replacement from nonfood cellulosic feedstock’s including dedicated energy crops such as fast-growing grasses and agricultural waste like bagasse, corn stalks, wheat straw and wood chips.

ü  Bio-diesel from Jatropha, palm oil, algae, grass etc.

BIOMASS FOR DIRECT COMBUSTION IN AN ELECTRIC POWER PLANT

ü  Agricultural waste

ü  Dedicated, fast-growing energy crops such as grass or trees

ADVANTAGES OF GIANT KING GRASS

Supports China´s national priorities

ü  Renewable and locally produced non-food energy

ü  Cleaner environment with reduced carbon emissions

ü  Improved agriculture to feed the population

Fast growth produces much higher yield per hector of land

ü  Much higher productivity than switchgrass or miscanthus or food crops

ü  Land can support both food and fuel needs

ü  Can grow on marginal lands as well

 

PROVIDES MULTIPLE OPPORTUNITIES – FEEDSTOCK FOR LIQUID BIOFUELS, AS COAL REPLACEMENT FO ELECTRICITY GENERATION, RENEWABLE METHANE AND ANIMAL FEED.

 

ADVANTAGES OF GIANT KING GRASS.

ü  Rapid growth to 4 Meters height

ü  Very high productivity – up to 350 Tones/hectare (wet)

ü  Perennial grass with 7 year life

ü  Best in tropical and subtropical areas.

-          4 or more harvests per year possible

-          Little growth below 10ºC, frost will kill tops, roots can survive

 

ORIGINALLY DEVELOPED AS FEED FOR COWS, SHEEP, PIGS, FOWL AND FISH

·         Suitable as fresh grass, silage or dried and processed into meal

 

Giant King Grass

·           Natural hybrid of Pennisetum Purpureum (also known as Elephant grass or Napier grass)

ü  Not Genetically Modified

·           Widely adaptive and stress resistant

·           Modest need for fertilizer

·           No pesticide needed in most cases

·           Suitable for wide range of soils including acidic red loam and mildly saline soil

·           Can be planted on dry lands, paddy fields, hillsides, plains

·           Needs more than 100days of sunshine per year, 800mm rain or irrigation

·           Propagated by division or seedlings

 

GRASSOLINE

üGRASSOLINE – a new term for renewable, low carbon liquid biofuels made from grass.

-          EXAMPLES – Cellulosic ethanol, methanol and green gasoline

DOES NOT USE FOOD CROPS SUCH AS CORN FOR ITS PRODUCTION

-          Does not cause high food prices and resulting world hunger

NOTE: In 2008 one third of the US corn crop was used to make ethanol.

 

CO-FIRING COAL AND BIOMASS

ü  An existing coal-fired electrical power plant can be modified to burn biomass instead of coal for up to 30% of its fuel

-          Grass, wood or other agricultural products

ü  Carbon dioxide smokestack emissions are the same as 100% coal, but the next crop of grass adsorbs the carbon dioxide emitted from the burned grass as it grows.

ü  Simplest and fastest way to partially clean up coal power plants and introduce renewable biomass fuels on a large scale

-          Converting existing coal power plants, compared to building new plants.

 

TREND TO 100% BIOMASS POWER PLANTS

·         FirstEnergy in Ohio, USA is converting an old coal-fired power plant to 100% biomass

-          Preferable to upgrading the emissions controls of the coal or converting to natural gas

 

·           DRAGON POWER IN CHINA has built and operates 19-100% biomass power plants.

-          12 to 30 MW, operating on agricultural waste

-          Benefits from China´s substantial subsidies for Biomass generated electricity

·         BIOMASS POWER PLANTS ENCOURAGED IN INDIA

·         BIOMASS CAN PROVIDE ELECTRICITY 24 HOURS A DAY

-          Solar only when sunny, wind only when windy

-          Agricultural waste such as corn straw, wheat straw and wood chips is currently used for fuel – however quantity and quality of agricultural waste varies with season

-          Dedicated energy crops are desired for 50% or more of power plant fuel requirements – Reliable with consistent quality

 

GIANT KING GRASS AS DEDICATED ENERGY CROP

·         30MW grass-fired electricity generating plant needs 460 tones of grass every day

·         Average household in Shanghai uses 1200 KWh/Year or average power of 0,14Kw (Average household in the US uses 11,200 KWh/year – 1,3KW)

·         30 MW plant can supply 214 000 Chinese households

·         30 MW power plant requires 1000-2200 hectares of land (using Giant King grass with yield of 350 Tonnes/hectare wet and 75-175 dry)

·         One Hectare can provide electricity for 98-24 Chinese households

 

ROLE OF BIOMASS FOR ENERGY-SUMMARY

·         Analysis shows that there is enough land on Earth to grow food and fuel as well if the crop has high productivity (Yield) – for use in liquid biofuels and for direct combustion

·         Direct combustion of biomass allows 24 hour electricity generation – Solar energy only when the sun shines – Wind energy only when the wind blows

·         Biomass together with solar, Wind, Kinetic and Ocean power can make a big contribution – all alternative fuels are currently more expensive than coal or oil and need government subsidies.
