Hydrogen – supply and applicationsHydrogen is the link between renewables and transport

Renewables Electrolysers Hydrogen gas store Power regeneration

Intermittent renewable power will eventually require the grid to store energy. Hydrogen will be an attractive pathway

Hydrogen powered transport will be an

important part of the future

2H2E

SupplyBrown hydrogen will help build the case for green hydrogen

Presently, hydrogen is used as a chemical and is commonly produced in large quantities Highly efficient and cost effective process Relatively simple process Relatively inflexible

In the future, hydrogen produced by electrolysis is a way of capturing energy from excess renewables

CH4+ H2O = CO + 3H2

4-5 kWhrs + H2O = O2 + approx.1m3 H2(Electrolyser)

Finally when the energy is

released the only bi-product

is water

Improving how the public perceive the risks of hydrogen is our top issueHydrogen is a safe gas when engineered correctly

Its properties are: Defuses readily Extremely flammable Gas at atmospheric temperature and pressure Colourless Odourless Tasteless Smallest molecule Lightest specific density (14 times lighter than air) Non-toxic, simple asphyxiant Non-corrosive Metallurgical: hydrogen embrittlement Normal boiling point: -253 °C

The composition of town gas:

Carbon Dioxide 19.5 % Carbon Monoxide 3 %

Methane 28.5 % Hydrogen 49 %

We lived with hydrogen all around us before

ApplicationsExamples of projects that socialise the use of hydrogen

Next year, BOC and a consortium plan to have 10 boats on a boating lake in

London

In partnership with Oxford Univ. The car will attempt

the eco-marathon car world record later this year

BOC ECH2O

BOC, as a sub-contractor to BP have supplied the

refuelling technology and hydrogen to the London FC

buses

CUTE London buses

BOC sponsored, technically supported and

supplied the hydrogen

Trafalgar Square Xmas lights powered by H2

The best projects combine good PR with knowledge
