Integrated coal Gasification Combined Cycle (IGCC) powerplant is the most environmentally friendly coal-fired power generation technology. Most importantly, coal gasification offers the immediate opportunity to generate power with near zero greenhouse gas emissions and the pathway to a future hydrogen economy.
Description
Coal gasification is the process of converting coal to a gaseous f
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
power or DTP is a new and untested method of tidal power generation. It would involve creating large dam-like structure extending from the coast straight to the ocean, with a perpendicular barrier at the far end, forming a large 'T' shape.
The plant is to open the existing dam to allow the circulation and exchange of water between the Lake Sihwa and the sea.
The tidal plant will improv
What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments

High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
