The increasing availability of energy and the increasing energy needs, demanding the development of alternative energy as a substitute for energy that has been used so far. Several alternative energy substitutes have been developed, one of which is the development of hydrogen-fueled alternative energy.

‘In accordance with its role, BPPT’s Center for Material Technology (PTM) develops alternative energy to address the electrical problems that Indonesia now faces, even for oil fuel substitutes that we have long used’, said Eniya Listiani Dewi from PTM in her office, yesterday (22/2).

Hydrogen, according to Dewi, is the state of the art of technology in today’s world. Especially in developed countries, they already apply this technology to automotive and housing. ‘Almost all the big automotive companies, started issuing hydrogen-fueled cars. Even in Japan, residential areas have implemented this application to generate electricity for every home’, he said.

This hydrogen is a secondary energy produced from natural energy such as petroleum, coal and natural gas. In addition, hydrogen can also be produced through the processing of methanol gas and organic waste that produces methane gas.

‘Together with the team, we’ve produced several hydrogen modules in the form of fuelcells ranging in capacity from 5 watts to 1kilowatt. We choose in the form of fuellcell because of its compact shape like the battery shape in general, in addition to not causing noise’, continued Dewi.

On the same occasion, Lies Wisodjodharmo Program Manager of Fuelcell BpPT Technology Development Activities said that his team has also applied this fuell cell to motors with a capacity of 500 watts. The results of the test found that I liters of hydrogen gas can travel as far as 1 km. When compared to regular-fueled motors, the use of hydrogen is much more efficient in terms of cost per kilo incurred.

‘Actually natural gases such as LPG and LNG, can already reduce the amount of carbondioxide produced by up to 57% compared to petroleum which 100% produces carbondioxide. But with hydrogen, the rate released can reduce by up to 78%. This shows that hydrogen is very environmentally friendly’, lies said.

Dewi added, in the agenda of road map research, in 2025 Indonesia targets to install 250 megawatts of energy mix or renewable energy. ‘At that point, Indonesia will need 3.6 million m3 of hydrogen per day. This needs to be supported by infrastructure readiness, as this fuelcell is highly dependent on hydrogen sources as local raw materials, so we are not dependent on imported products
