Hydrogen contains 3x more energy per weight than jet fuel, and enables vastly longer trips. It is the most energetic non-nuclear fuel and aviation is the most weight-sensitive application.
Carbon-free
Hydrogen is a true zero-carbon fuel. It is made from water and its only emission is water.
Affordable
Hydrogen will be at cost parity with jet fuel starting in 2025, with costs decreasing exponentially.
Safe
Hydrogen is significantly safer than jet fuel. It has a great safety record in hydrogen-powered vehicles.
What is hydrogen?
Hydrogen is a clean alternative to methane, also known as natural gas.It’s the most abundant chemical element, estimated to contribute 75% of the mass of the universe.
Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course, humans. But while it’s present in nearly all molecules in living things, it’s very scarce as a gas – less than one part per million by volume.
Hydrogen can be produced from a variety of resources, such as natural gas, nuclear power, biogas and renewable power like solar and wind. The challenge is harnessing hydrogen as a gas on a large scale to fuel our homes and businesses.
Why is hydrogen important as a future clean energy source?
A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air).
For many years, we’ve used natural gas to heat our homes and businesses, and for power stations to generate electricity. In the UK, 85% of homes and 40% of the country’s electricity currently relies on gas; in the US, 47% of households rely on natural gas and 36% on electricity1.
Methane is the main constituent of ‘natural gas’ from oil and gas fields. We’ve continued to use natural gas because it’s a readily available resource, it’s cost effective and it’s a cleaner alternative to coal – the dirtiest fossil fuel that we historically relied on for heating and to generate electricity.
When natural gas is burnt, it provides heat energy. But a waste product alongside water is carbon dioxide, which when released into the atmosphere contributes to climate change. When we burn hydrogen, the only waste product is water vapour.
What is the difference between blue hydrogen and green hydrogen?
Blue hydrogen is produced from non-renewable energy sources, by using one of two primary methods. Steam methane reformation is the most common method for producing bulk hydrogen and accounts for most of the world’s production. This method uses a reformer, which reacts steam at a high temperature and pressure with methane and a nickel catalyst to form hydrogen and carbon monoxide.
Alternatively, autothermal reforming uses oxygen and carbon dioxide or steam to react with methane to form hydrogen. The downside of these two methods is that they produce carbon as a by-product, so carbon capture and storage (CCS) is essential to trap and store this carbon.
Green hydrogen is produced by using electricity to power an electrolyser that splits the hydrogen from water molecules. This process produces pure hydrogen, with no harmful by-products. An added benefit is that, because this method uses electricity, it also offers the potential to divert any excess electricity – which is hard to store (like surplus wind power) – to electrolysis, using it to create hydrogen gas that can be stored for future energy needs.
Yes. There are already cars that run on hydrogen fuel cells. In Japan there are 96 public hydrogen refuelling stations, allowing you to fill up just as you would with petrol or diesel and in the same time frame as a traditional fuel car. Germany has 80 of these hydrogen stations and the United States is third with 42 stations.
Hydrogen is also an exciting lightweight fuel option for road, air and shipping transportation. The international delivery company DHL already has a fleet of 100 ‘H2 panel vans’, capable of travelling 500kms without refuelling.
What are the potential brakes to speeding up hydrogen use as a clean energy?
For hydrogen to be a viable alternative to methane, it has to be produced at scale, economically and the current infrastructure needs to be adapted.
The good news is that hydrogen can be transported through gas pipelines, minimising disruption and reducing the amount of expensive infrastructure needed to build a new hydrogen transmission network. There would also be no need for a culture change in our home lives, as people are used to using natural gas for cooking and heating, and hydrogen energy equivalents are emerging.
The fall is my best seasons of the year. The beautiful colour’s, of the season, the smell of roasted chestnuts and Christmas by far my favourite time of the year but also the end.
Yes, I know Christmas is already in winter, but not to me. Fall, the crops festivals, thanksgiving and Christmas are all part of one big and widder time when we should look into our self’s and analyse our self’s make a retrospective about our self’s.
We must focus on our selves without been selfish look about each other but all the rest.
We have a greater mission which is enlighten ourselves evolve to a greater level in mind and spirit only then when we reach that level, we will be able to understand our mission our world.
