Renewable Energy Sources: Geothermal and Biomass

In previous post, I shared brief overview about common renewable energy sources, such as solar power, wind power, and hydro power. In this post, I want to continue sharing about other renewable energy sources, which are geothermal, biomass, and energy sources from sea (wave, tidal, and ocean thermal energy conversion).

Geothermal Energy

Geothermal energy is renewable and offer more advantages than other renewable energy sources, such as hydro, wind, bio energy, biomass, and wave energy. It has high degree of availability, low land use, insignificant dependence on weather conditions, and comparatively low visual impact.

Global installed capacity of geothermal power has reached 14.4 GW, with the US as the largest geothermal country so far. Read More

Renewable Energy Sources: Solar, Wind, and Hydropower

Renewable energy is increasing around the world. This is because energy from fossil fuel becomes scarce. In Indonesia, based on RUPTL 2018, government plant to increase geothermal energy source from 5% in 2018 to 12% in 2025. The percentage of other renewable energy is 0% in 2018 to 2% in 2025.

What is renewable energy? Renewable energy is generated from sources that naturally replenish themselves and never run out.

Renewable energy could be alternative to combat with climate change because it does not generate direct greenhouse gas emission. The only emission that renewable energy generate is indirect greenhouse gas emission, which are from installation, operation, and maintenance. Read More

Potential geothermal projects in Indonesia

Potential Geothermal Project in Indonesia

Today I stumbled upon Investment Catalog while searching for certain information. The catalog was issued by Ministry of Energy and Mineral Resources, Republic of Indonesia. And guess what? I found something interesting: potential geothermal project in Indonesia.

The catalog was actually 2017 version. However, I think it is still quite relevant.

For you, who are consultant like me, EPC contractors, vendors, or licensors, you may be interested on this information. You can download the publication to read detail information about those projects. In this post, I want to share you potential geothermal project in Indonesia and its status based on publication on media.

There are six potential geothermal projects in Indonesia. Those are geothermal project in Gunung Galunggung , Gunung Hamiding, Gunung Wilis, Gunung Simbolon Samosir, Graho Nyabu, and Gunung Geureudong. Some of the name are familiar for me. Read More

Several Natural Gas Dehydration Methods and Range of Application

In almost every gas processing plant, there will be natural gas dehydration unit. Sometimes, it is called dehydration unit (DHU) or dehydrator. When, I was working in Tripatra and involving in Senoro Gas Development Project, the facilities consisted of dehydration unit as one of them.

Natural gas dehydration unit is an important facilities in onshore and offshore gas processing plant. Its function are:

  • To mitigate risk of water condensation, which leads to flow capacity issues (pipeline clogging and blocking)
  • To prevent hydrate formation or to minimize corrosion
  • To ensure smooth operation in downstream facilities. For example, gas pipeline is usually required 4-7 lb/MMSCF water content (87.2-152.6 ppm). For cryogenic unit (to produce LNG), water content in gas shall be less than 1 ppm. For CNG plant, before entering compressor unit, water content shall be reduced to maximum 3 lb/MMSCF to meet product specification.
