Trends and Opportunities in gasification


Entrained Flow Gasification

Trends and OpportunitiesWith a huge variety of uses for syngas and H2, gasification is ideally suited to generate additional revenue from every ton of feedstock produced, while meeting even the strictest environmental regulations.


What is gasification?

Main Reactions:C + ½ O2 => COC + CO2 2 COC + H2O => CO+H2

CO + H2O CO2+H2

H2O

Sulfur

Feed is … Gasification is … Products are …

• Sulfur (S) • Nitrogen (N) • Ash (rock)• Trace Elements

(e.g. Mercury)


Market trends and opportunities for Gasification

• High dependency on environmental legislation • Currently weak demand for CO2 capture and storage solutions

• Availability and low energy density of biomass drive gasifier capacity and location

Alternative Transportation Fuels (CtL/BtL2)High-quality diesel from FT3-synthesisFuels with higher biomass content

Chemicalse.g. Methanol, Polypropylene, Ammonia,…

Synthetic Natural Gas

Refinery Hydrogen For upgrading products in refineries or in oil sands processing

Power • Large scale IGCC4 with CCS5 as environmental friendly alternative to Steam Power Plants

• Small scale power production via high efficient Biomass gasification systems

Is and will remain the market with the highest realization potential (CtC/BtC1)

Increasing demand for cleaner and lighter fuels are the drivers for higher H2 consumption within refineries

Serious alternative for (coal rich) countries, with lack on cheap natural gas availability

Volatile oil and gas prices, security of supply concerns and climate protection cause search for alternative fuel sources

Products … Trends and Opportunities …


BtL1 / BtE2 – Global gasifier market

• BtL projects mainly focused on markets for industrial scale chemical / transportation fuels production

• BtE mainly used for small scale power generation Japan: Feed-in-tarif available

Western Europe• Large scale projects in Netherlands and

Finland under development• Subsidies available

• Gasifier application in renewable applications forecasted to grow within the next years/decades• Short / Mid-term market will be dominated by small / medium-scale applications• Large scale lighthouse projects under development• Availability and low energy density of biomass drive gasifier capacity and location• Subsidies or feed-in-tariffs are key for biomass

• Financial decision guided by size and location, availability of feedstock, its energy content and processing costs

• Insufficient grid expansion (developing countries)

• Public opinion against fossil fuel plants (industrialized countries)

Asia Pacific Region (India/Indonesia/Malaysia/Thailand/Vietnam/…):

• Could support electrification of rural and remote areas, growth rate for small/medium scale applications

China• Underdeveloped as of today, but

government policy and subsidies announced

South-America:•Opportunities for BtL/BtE at sugar plantations (bagasse) and croplands

USA/Canada/Mexico:• Push through subsidies

Block flow diagram

Preliminary engineering results:

• Ship transport by Handymax or Panamax bulk carriers

• Buffer storage envisaged for 2 weeks, possibly in pyramid silo’s

• Density of torrefied material is fundamental for performance of gasifier

• Ash content of biomass is fundamental for gasifier design

• Additional bio-fuel storage is required

WoodSpirit is…

• an EU showcase for conversion of lignocellulose to biofuels

• a first commercial scale demonstration of gasification in combination with torrefaction

• and an important alternative to CCS

• an innovative Renewable Energy Source

• able to improve energy independence

• a generator of sustainable second generation biofuels

• 500 million liters biofuels = ~3 billion green car kilometers per year

• about mandatory EU 2020 targets: European Renewable Energy Directive (RED).

• In 2020 at least 10% of all energy used in transportation has to be renewable

• able to generate an significant additional CO2 savings of 900 kton per year

• a boost for a bio-based economy

Torrified BiomassFeedstock

Siemens Expands Feedstock Capability with Biomass• Testing indicates blends of non pre-treated biomass with coal or petcoke

up to approx.. 20% depending on the biomass type are possible• Torrefaction is necessary for pure biomass feedstock or blends with

a significant portion of biomass


What is torrefaction?


ECN‘s/Andritz torrefaction technology


Summary

First time large scale application of entrained flow gasification with biomass in a project-finance environment

EU-funded project performed by international consortium to follow the European Energy Directive

500 millions liters biofuel will generate CO2 saving of 900 ktons per year

Torrefaction shows one way to unify the inhomogeneous feedstock as basis for use of biomass within a complex industrial plant

Entrained Flow Gasification pave the way for large throughput biofuel projects requiring very clean syngas
