The Race to Fusion power - what, why and who and how

Preview:

DESCRIPTION

A talk prepared for YR11 physics students, outlining what fusion power is, arguments for debate why fusion power will be needed and who the the competitors are and how they will plan to achieve break-even fusion

Fusion PowerWhat?

Why?How?

Fusion

and counting...

Burning Up• Fossil Fuels are largest source of energy

• Average coal-fired plant burns 10,000 tonnes per day

• over 7 billion tonnes of coal every year world wide

• plus about 1 Cubic Mile of Oil per Year

= Lots of air pollutionhttp://www.iea.org/aboutus/faqs/coal/http://www.theoildrum.com/node/2186

So Whathappens IF...... we stay on this track?

Over 1,000 new coal-fired power plants planned

Acceptable Future?

"If the average energy consumption per person

doubles, this country will be choked to death by polluted air"

In the US, the median

person pays $1 in 6 for

energy

$9,000/year, $22 a day

Worldwide:

$1 a day for energy

on $3 a day

income

Fission – an Alternative?

•Cost of Fukushima Daichi disaster - $300bn and counting…

What IF...we change track?

Renewables?• Won‘t scale fast enough

• Cannot match Coal / Oil for cost

• Not suitable for baseload power

• Energy storage still in early stages

„Conventional“ Fusion

In the Race for D-T Fusion

13th Feb 2014

„…$5 billion National Ignition Facility, where scientists recently got a tiny bit closer to their goal of creating a controlled fusion reaction…”

Still just a big hole in the ground...

Magnetised Target Fusion

General Fusion (MTF)

• Targeting 2018 for Net Gain

High-β (beta) Fusion Reactor

Lawrenceville Plasma Physics Dense Plasma Focus

Goal product: 5 MW Focus Fusion generator

At approx $1M / unit

Lower projected cost than any other energy tech

$60/kW or 0.2 cents/kWh

Focus Fusion Timeline

2013-2014: Scientific demo

2017-2018: Commercial prototype

2019: Mass manufacture

Independent Review Assessment

“a much higher

level of investment is

warranted“
