The Hydrogen City: How Hydrogen Can Help to Achieve Zero Emissions
Cities are drivers of growth and prosperity, but also the main contributors of pollution. Can hydrogen fuel the growth of cities with clean power?
In the modern context, cities create somewhat of a paradox.
While cities are the main drivers for improving the lives of people and entire nations, they also tend to be the main contributors of pollution and CO2 emissions.
How can we encourage this growth, while also making city energy use sustainable?
Resolving the Paradox
Today’s infographic comes to us from the Canadian Hydrogen and Fuel Cell Association and it outlines hydrogen technology as a sustainable fuel for keeping urban economic engines running effectively for the future.
The Urban Economic Engine
Today, more than half of the world’s population lives in cities, and according to U.N. estimates, that number will grow to 6.7 billion by 2050 – or about 68% of the global population.
Simultaneously, it is projected that developing economies such as India, Nigeria, Indonesia, Brazil, China, Malaysia, Kenya, Egypt, Turkey, and South Africa will drive global growth.
Development leads to urbanization which leads to increased economic activity:
The difficulty in this will be achieving a balance between growth and sustainability.
Currently, cities consume over two-thirds of the world’s energy and account for more than 70% of global CO2 emissions to produce 80% of global GDP.
Further, it’s projected by the McKinsey Global Institute that the economic output of the 600 largest cities and urban regions globally could grow $30 trillion by the year 2050, comprising for two-thirds of all economic growth.
With this growth will come increased demand for energy and C02 emissions.
The Hydrogen Fueled City
Hydrogen, along with fuel cell technology, may provide a flexible energy solution that could replace the many ways fossils fuels are used today for heat, power, and transportation.
When used, it creates water vapor and oxygen, instead of harmful smog in congested urban areas.
According to the Hydrogen Council, by 2050, hydrogen could each year generate:
- 1,500 TWh of electricity
- 10% of the heat and power required by households
- Power for a fleet of 400 million cars
The infrastructure requirements for hydrogen make it easy to distribute at scale. Meanwhile, for heat and power, low concentrations of hydrogen can be blended into natural gas networks with ease.
Hydrogen can play a role in improving the resilience of renewable energy sources such as wind and solar, by being an energy carrier. By taking surplus electricity to generate hydrogen through electrolysis, energy can be stored for later use.
In short, hydrogen has the potential to provide the clean energy needed to keep cities running and growing while working towards zero emissions.
The Evolution of Hydrogen: From the Big Bang to Fuel Cells
Hydrogen and fuel cell technology harnesses the power of the universe to bring clean energy on Earth. Here is its potential.
It all started with a bang…the big bang!
The explosive power of hydrogen fueled a chain reaction that led to the world we have today.
Now this power is being deployed on Earth to supply the energy needs of tomorrow.
Visualizing the Power of Hydrogen
Today’s infographic comes to us from the Canadian Hydrogen and Fuel Cell Association, and it outlines how hydrogen and fuel cell technology is harnessing the power of the universe to potentially fuel an energy revolution.
What is Hydrogen, and How’s it Used?
With one proton and one electron, hydrogen sits at the very beginning of the periodic table.
Despite hydrogen being the most common molecule in the universe, it is rarely found in its elemental state here on Earth. In fact, almost all hydrogen on the planet is bonded to other elements and can only be released via chemical processes such as steam reforming or electrolysis.
There are five ways hydrogen is being used today:
- Building heat and power
- Energy storage and power generation
- Industry energy
- Industry feedstock
However, what really unleashes the power of hydrogen is fuel cell technology. A fuel cell converts the chemical power of hydrogen into electrical power.
Hydrogen Unleashed: The Fuel Cell
In the early 1960’s, NASA first deployed fuel cells to power the electrical components of the Gemini and Apollo space capsules. Since then, this technology has been deployed in everything from the vehicle you drive, the train you take, and how your favorite products are delivered to your doorstep.
Nations around the world are committing to build hydrogen fueling stations to meet the growth in adoption of fuel cell technology for transportation.
Hydrogen: A Green Energy Solution
Hydrogen fuel and fuel cell technology delivers green solutions in seven ways.
- Decarbonizing industrial energy use
- Acting as a buffer to increase energy system resilience
- Enabling large-scale renewable energy integration and power generation
- Decarbonizing transportation
- Decarbonizing building heat and power
- Distribution energy across sectors and regions
- Providing clean feedstock for industry
According to a recent report by McKinsey, hydrogen and fuel cell technology has the potential to remove six gigatons of carbon dioxide emissions and employ more than 30 million people by 2050, all while creating a $2.5-trillion market.
This is technology that can be deployed today, with the potential to transform how we live and power our economies in a sustainable way.
