Biomass presentation to ISM Grade 3 Feb. 2011

BiomassA sustainable source of

energy

Grant Hauber

Biomass is any living plant matter

Biomass energy is energy made from something

that is or once was plant matter

Types of

Biomass is the oldest source of energy

As a fire burns down, it gets hotter

Heat can be used to cook, boil water

Harnessing fire to make steam

Biomass

High Heat

Boiler

Steam

Steam spins the turbine blades

Turning Biomass into Electricity

Rotating magnets create electricity

Pipes filled with water are heated to make steam

Inside a biomass steam boiler

Fire heats the water

What biomass can you burn to make fire?

What is this?

How much of this do you eat?

Rice

Rice husk1 bowl = 1000 grains of rice

1 bowl per day x 365 days per year

= 365,000 grains of rice per year

365,000 grains of rice 36,500 grains per kg

= 10 kg per year per person

13,000,000 people in Manila x 10 kg per person = 130,000,000 kg

Rice husk mountain!

Farmers often burn their crop waste to get rid of it

How can we stop this?

Biomass Power!

Grown Biomass = Energy Crops

Bringing it all together…with no waste!Electricity and Steam are used by the Paper

Mill

Biogas

Farms can be dirty places

Making food can leave behind a lot of nasty waste

Food or animal waste ferments in

the pond, releasing methane gas

Methane is highly

flammable!!

Humans also generate lots of waste! Covered landfills capture methane like a balloon

This methane can be used to generate electricity

Biogas Capture Process

Thick rubber sheets cover the pond

Methane gas builds up under the rubber sheet

Tank type biogas plant
