Green-H2Islands

The initial situation

The power supply on the islands of Southeast Asia are facing the challenge of creating a reliable infrastructure in areas that are geographically difficult to access. Many remote islands depend heavily on expensive and risk-prone diesel generators, which increases not only costs but also environmental impact. As a result, access to electricity is often limited to only a few hours a day in many island communities.

The approach

The Green-H2Islands project deals with the current inadequate power supply on the islands of Southeast Asia. It is intended to demonstrate the feasibility of a 100% renewable, safe and accessible power supply on the basis of solar energy and hydrogen.

The objectives and measures

The project has three main objectives:

1) The development of an open-source dimensioning tool for hydrogen-based energy systems on islands, which can be used via a user-friendly web application. This enables the actors involved to determine the system dimensions using own data for their location.

2) The construction of a demonstration plant on the Thai island of Koh Jik based on the developed tool. For this purpose, the existing PV battery-diesel system is being transformed into a PV-hydrogen system to achieve a fossil-free power supply.

3) The development of a potential study in which the expansion potential of PV-hydrogen island systems in Southeast Asia is identified, thus demonstrating the replication potential of the implemented project on the other approx. 25,000 islands in Southeast Asia. The study takes into consideration both technical and socio-economic factors.
