Preservasi Peralatan: RERSERVASI PERALATAN. Geothermal Power Plant Impact of Scale and Corrosion
According to an April 2021 report by Global Industry Analysts, the global geothermal energy market is expected to reach US $8.9 billion by 2027, up from US $4.7 billion in 2020, with the US market estimated at US $1.4 billion in 2020.
Geothermal energy systems fall into three categories, as outlined by the US Energy Information Administration
- Direct use and district heating systems
- Geothermal power plants
- Geothermal heat pumps
This paper is focused on corrosion and scale control in the geothermal power generation market.
Geothermal power plants are categorized as the following:[3]
- Dry Steam – harnesses steam produced naturally in the geothermal reservoirSimplest and oldest
- Flash Steam – converts high-pressure hot groundwater to steamMost common
- Binary – uses geothermal hot water as the heat source to turn a secondary liquid to steamMost recent design
The market for dry steam plants is estimated to grow by 8.4% CAGR to US $2.4 billion by year’s end 2027. Binary plants will have a projected 8.8% CAGR. The flash steam segment is expected to see a 10.6% CAGR propelled by growth in the USA, Canada, Japan, China, and Europe, developing from an estimated US $2.1 billion regional market share in 2020 to US $4.3 billion in 2027, with China growing at the fastest rate. Asia-Pacific leaders for the flash steam sector will include Australia, India, and South Korea (US $1 billion regional forecast for 2027).[
