An Official Publication of the Renewable Hydrogen Network
This is a short book entitled Renewable Hydrogen, which outlines the basics regarding RH₂, and highlights compelling case studies from around the world in aim to accelerate the social movements towards an energy shift. More details »
Grid Free RH₂ Machine grand debut
at Omotesando COMMUNE 246!
Don’t miss it! A grid free RH₂ system is up and running at COMMUNE 246, a community space for the active dialogue on our future city. Solar panels power your PC while any surplus electricity is used for water electrolysis to make hydrogen and store energy. During the night, the energy stored in hydrogen form is released through a fuel cell. A simple off-grid energy system made from renewable energy and hydrogen in the heart of Tokyo!!
Renewable hydrogen (RH₂) is not rocket science.
Renewable Hydrogen or RH₂ is a sustainable form of energy from water and various types of renewable energy filling our surrounding environment.
Renewable energy cannot always promise a constant supply of energy. Some days electricity is generated more then used and other days there is not enough. This is where hydrogen enters the renewable energy equation as an energy storage method to maximize the usage and potential of renewable energy.
The basic steps of RH₂: MAKE it, STORE it, and USE it
1. On the days when electricity is generated more then used, this surplus electricity will be stored at your convenience. Water (H₂0) is split into hydrogen (H₂) and Oxygen (O) by a process called electrolysis.
The basic concept of electrolysis is middle school chemistry. It is simply put, a electrical current passing through an element to separate it into smaller parts.
2. The separated hydrogen is stored which can be done in many ways : In pressurized tanks as gas, as liquid, or absorbed into metal. The amount stored is scalable and its life span is longer compared to conventional batteries. Hydrogen is a diverse energy carrier.
3. It generates electricity, heat, and run cars when combined back with oxygen only releasing the by-products of heat and water.
Water, oxygen, and hydrogen creates an endless cycle of energy. There are no toxic by-products and the air and water are left clean. Centralization of power and money is released for the common good. The endless cycle of energy does not create war or poverty and brings all life closer together.
Renewable hydrogen projects are springing up across the world.
Take a look into the Case studies page and see the energy shift in action.
