Abstract

Achieving the national energy mix in 2025 requires accelerating capacity development in new and renewable energy.Utilization of new and renewable energy potential aims to achieve the national energy mix target. One of the new renewable energy that has the potential to be developed in Indonesia is Biomass for fuel. One of the efforts to increase the use of biomass is by Cofiring. Biomass can be an effective alternative energy, in order to minimize the use of fossil fuels. The biomass is mixed into the coal bunker. The fuel mixture is flowed into the combustion chamber or furnace. Some of the advantages of doing biomass in PLTU include relatively lower investment and better environmental impact when compared to 100% coal. Cofiring PLTU has an effect on exhaust emissions, in evaluating the impact of exhaust emissions as a benchmark for environmental parameters, cofiring testing is carried out with reference to the Emission Quality Standard (BME).As a result, the effect of cofiring using 5% sawdust still has no significant effect on exhaust emissions at the CEMS (Continuous Emissions Monitoring System) PLTU. It is very possible that the type of coal used is still very influential on emission conditions, considering that the percentage of biomass used is still very small.

Abstract

The use fossil energy consumption in Indonesia is increasing along with population growth and industrial development. Fossil energy oil and coal can produce greenhouse gas emissions and environment pollution. The largest producer of CO2 emissions comes from exhaust gases in the production process and motor vehicles. Indonesia's energy mix target in 2025 is around 23% from New and Renewable Energy (NRE). Given the importance of using NRE, Indonesia is starting to look for alternative energy that is environmentally and sustainable, like hydrogen energy. Green hydrogen technology has the potential to be developed in Indonesia. Hydrogen production processes commonly carried out are through the electrolysis of water, methanol, and biomass. The use of hydrogen can be applied to motor vehicles and power plants. Hydrogen can reduce greenhouse gas emissions. However, Indonesia has problems in developing green hydrogen technology, one of which is the high production cost, so it requires other parties to develop it.
