Portable Lab Device for Green Hydrogen’s

Non-Toxic Catalyst Research

Background

H2Lyte Sen

Problems

• Measurement challenges
• Lack of practicality of conducting green-catalyst experiments
• Time-intensive process for setup, execution, and long-lead time when waiting for results (waiting for gas bubbles)
• Potential toxic chemicals as by-product of the electrolysis process

Goals

• To measure various parameters to find the effective non-toxic, local-based, catalyst, e.g EC, pH Levels, Temperature, Contaminants
• To measure toxicity levels for toxic chemical management and safe disposals

Furthemore, the system can be embedded as well at the main hydrogen generator detect/measure the toxicity levels as a result of the electrolysis process

• Can be used as an educational toolkit for the communities, to promote citizen science movement, making science experiments less intimidating to the locals
• Moreover, can be used to monitor water quality for other purposes in the Hydrogen Village, e.g aquaculture, hydroponic, etc.

Idea #1:

Portable Biomaterial Research Workstation

Rantang lab?

Why?

Biomaterial is now an emerging and growing field in Indonesia, especially since we have abundant of organic and natural resources. Based on my personal experiences for the past 3 years experimenting with biomaterials, I encounter several pain-points that I would love to solve to accelerate biomaterial research & exploration.

​

1. Needs so many equipments and supplies to start with

Because of different functions needed in doing the biomaterial work, even to do small samples experiments. This can be expensive for starters.

​

• Not practical for mobilization and for on-site experiments

Especially if you have to do workshops to schools or communities, or if you need to do the experiments in remote area, you need to carry a lot of stuffs

We basically need a kitchen, but not all place offer an open kitchen, so you gotta bring your own kitchen with you.

​

• Currently biomaterial research & experiments are still not consistent

Making it a challenge to compare one material performance to other and re-calibrate formula because of differences in size, measurements, etc.
