Hydrogen is a versatile

energy carrier that owns

unique edges in tackling

climate change.

Hydrogen is a versatible energy source that can be applied in
different areas. It can be used in a wide range of applications
regarding its attributes: storable, high energy content per unit
mass and its readily produced rate at industrial scale.

Hydrogen Produced

Through Fossil Fuels

%

Current hydrogen production

pathways rely heavily on

fossil fuels, with significant

CO2 emissions.

Clean hydrogen production methods are hindered by low
yield and high cost, causing the dominance of fossil
fuel-based production. Here, we are seeking to develop a
cheap and environmentally friendly hydrogen production
mechanism. On the left, it is a comparison between popular hydrogen production routes.

Project Eco. H

We introduced R. palustris

as a chassis for hydrogen

production and modified its

metabolic pathways.

Rhodopseudomonas palustris is a gram-negative bacterium
that can synthesize hydrogen under anaerobic conditions. In
order to increase its hydrogen production, we decided
to knock out two of its genes: uppE and hupS.

Project Eco. H

A hydrogenase with higher

efficiency is introduced, to-

gether with semiconductors

to enhance light absorbance.

In order to further improve the hydrogen production efficiency
of E. coli, we chose a membrane-binding hydrogenation
enzyme Oxygen-tolerant [NiFe]-hydrogenase from Hydrog-
enovibrio marinus MH-110.

Project Eco. H

We developed a bioreactor

capapble of dilute and

analyze fermentation

products on-site.

The device will allow researchers to monitor the fermentation
status in time and onsite, empowering them to rapidly opti-
mize the growth conditions. For greenhouse gas emission
sensitive projects, the onsite gas analysis also made carbon
accounting possible.

Project Eco. H

We have conducted appli-

cation research to study

how and where the solution

can be deployed.

Biohydrogen production is not only restricted in laboratories,
but is also open to a range of applications in the form of fuel
batteries, ranging from industrial use to products in daily
lives. Here, we studied such possibilities.
