We are heavily dependent upon fossil-based energy resources in our daily lives. These energy resources are used in household, industrial, and mobility. However, these energy resources bear several negative impacts in their transformation into energy. It releases high carbon dioxide (CO2), the main contributor to climate change, to the earth. In recent research published in Our World in Data, there is an increase of 85% in fossil fuel consumption in Indonesia over the last twenty years. It is therefore paramount to transition into renewable energy resources as they are readily available.

Renewable energy resources produce less carbon dioxide and are fairly economical and affordable compared to fossil-based energy. Cleaner, cheaper energy sources are need to support individuals and communities to be more resilient.

Balon Balon Ijo will provide local generation of clean, cheap energy utilizing the most abundant natural resource on Earth, water, and the power of the sun.

Green Hydrogen from the Sea

One of the renewable energy resources is hydrogen, clean natural gas that can be found in substances such as water and in other species.

Balon Balon Ijo, a hydrogen fuel cell extraction equipment powered by solar panels, was created by a team of engineers under the Balon Balon Ijo Project spearheaded by Cesar Jung-Harada to create better, and sustainable energy resources. Their hope is to contribute to minimizing the deteriorating impact of global climate change. Balon Balon Ijo, made mostly from a sustainable material, captures the water and separates the hydrogen atom material from seawater. The hydrogen is then turned into electricity in a fuel cell with the help of electric energy captured from the solar panels. The fuel cell's output can then be used for household use such as basic lighting, cooking, or to power electric bikes.   Balon Balon Ijo brings many advantages to its user. First and foremost, it brings economic advantages as it is more affordable than conventional fossil-based energy resources. Second, Indonesia is blessed with its abundant water supply, making it possible to mass-produce renewable energy resources without jeopardising the ecosystem of coastal or marine life. Last, it encourages people to participate in a sustainable lifestyle moving towards living with little or zero net emission.


The Balon Balon Ijo Project adopts the Balinese philosophy of Tri Hita Karana which espouses harmony and prosperity towards people and the environment.

Tri Hita Karana integrates perfectly with the three pillars of sustainability; economic, social and environmental.

Together with these foundations, the Balon Balon Ijo Project introduces global innovation to the Indonesian people and the world.

Q1 What is Balon Balon Ijo?

The Balon Balon Ijo is a speculative energy business that addresses the need for cheaper, cleaner energy. Balon Balon Ijo utilizes the most abundant element in the universe, hydrogen, to locally produce hydrogen energy.

Balon Balon Ijo is designed to be a system of modular pods, allowing for future expansion. It is made up of a two types of “Pods”:

  • The Solar Pod: Captures solar energy
  • The Balon Pod: Contains the equipment to make and store hydrogen

The demonstration pods have been made from locally sourced materials such as bamboo and reusing water bottles and styrofoam. The design is able to be adapted to locally available materials.

In the future we envision Balon Balon Ijo to be available to the public in three ways:

  • People are able to build their own using the information we provide
  • People could buy a kit available from a local partner
  • People could buy complete pods from a local partner

In the future we could integrate sensors in the pods and use distributed ledger technology/blockchain to issue eco-credits based of the production of hydrogen each pod produces per kilogram.

A DAO (decentralized autonomous organization), the Balon Balon Ijo Energy Cooperative, can be established that coordinates between the contributors and stakeholders of the system. SubDAOs could then form as needed to service the cooperative as needs emerge from building, harvesting, processing and distributing the hydrogen to market.

Q2 Why Hydrogen?

Hydrogen energy can be produced using renewable energy sources such as solar, wind, wave. When using hydrogen for electricity its by-products are water and heat. We chose hydrogen because it is a clean energy alternative to fossil fuels that is able to be produced and used locally.

Q3 How does it work? What can I use it for? How much power can the pods produce?

Power (such as solar or wind) is able to be used to split water (H2_2O) into hydrogen (H2_2) and oxygen (O) using a process called electrolysis.

Example uses of Hydrogen include:

  • It can be mixed with oxygen and burnt for cooking or for combustion in an engine
  • It can be be converted into electrical energy using a fuel cell and used like any other source of electricity such us powering an electric vehicle, running an electric appliance, even charging your mobile phone

Our demonstration model can produce 5 litres of Hydrogen per hour.

Q4 Where can this be set up?

The Balon Balon Ijo system can be setup anywhere, on the water, in a field, on a roof. The modular system means it can fit where needed and be expanded to meet local energy needs.

Q5 Who is this for?

Balon Balon Ijo is for everyone. We see Balon Balon Ijo as an opportunity for local communities to make their energy locally in a sustainable way in a P2P energy market or selling to local industries such as food markets or transportation.

In the future we envision the following types of users:

  • People who produce hydrogen to use for themselves, their family, their community
  • People who produce hydrogen to sell or trade to others
  • People who buy energy from producers
Q6 Can I get the pods now? Can I make one myself?

For now the pods are just a concept. More refinement in their design is needed. The idea is to have a set of simple designs and instructions that allow anyone with a little knowhow on building things and electronics to make their own.

We also have the idea that in the future simple to put together kits and plug and play versions of the pods will also be available, allowing those without the knowhow to get access to the technology.

Q7 What are the costs?

Our goal is to have the hydrogen produced by the Balon Balon Ijo pods be the same price or cheaper than LNG.

The Balon Balon Ijo design is opensource, meaning it is free for anyone to access and use to build their own.

Q8 Is this safe? Legal?

Hydrogen gas, like any other fuel source is flammable and should be managed accordingly.

Legal requirements, including use of property, land or water should be confirmed with local authorities. This also applies to the use of DAO (decentralized autonomous organization) and distributed ledger technology/blockchain to issue eco-credits based of the production of hydrogen each pod produces per kilogram.

Q9 What is next?

We will continue to work with local people to refine our design. We will also work with researchers to further develop the equipment for producing hydrogen to make it cheaper and more efficient.

Q10 How can I be kept informed of updates?

Balon Balon Ijo Against Fab Island Challenge Criteria

Does the project improve the well-being of the people involved?

Balon Balon Ijo will offer local communities the opportunity to generate their own energy to support their livelihoods. They could use that energy themselves or potentially trade that energy within their local community.

Does the project support development of local communities?

Balon Balon Ijo will support the development of communities by providing people with the means to generate hydrogen energy which they can use in their daily lives.

Is the project using sustainable materials or circular principles?

The Balon Balon Ijo pod structures are designed to be made from available materials, include reuse of items that would be thrown away, such as bottles or styrofoam to make the pods float.

Does the project rethink the application of technology?


Can the concept be replicated easily is other cities/countries?

The modular Balon Balon Ijo system allows it to be built and used anywhere. It is designed to be able to be replicated by anyone.

Is the project using out-of-the-box methodologies?

Balon Balon Ijo brings together modern technologies to produce hydrogen with traditional building methods for the pod structures. The flexible and simple design will allow for people to build the pod structures with what they have available locally.

What makes the Balon Balon Ijo concept different is the idea that anyone can make their own hydrogen energy and they do not need expensive equipment/tools to achieve this.
