Phasing the Heat: Challenges and implications of a coal phase-down in ASEAN

The ASEAN region homes the youngest coal power plants in the world. Partial or complete shutdown will give financial challenge to the plant owners/ investors and the utility companies who signed construction and operation contracts. The energy security and reliability of the power system would be a huge challenge for the countries and the region. Shutting a large portion of coal power generation down would require large-scale deployment of renewables to be able to supply the energy that is not served by putting coal plants offline.

Technology trends in forecasting renewable energy generation

Renewable energy forecasting is critical for integrating variable renewa­b­le energy resources like wind and so­lar power into the grid. Wind and solar power are heavily dependent on weather conditions, and thus their energy generation pa­tt­erns are quite erratic. This creates problems not only for grid operators who must account for these frequent fluctuations in their load management schedul­es, but also for power generators who ha­ve to pay hefty charges for deviation from scheduled energy generation.

What is Hydrogen and How Does it Fit into a Decarbonized Future?

Hydrogen provides a way to decarbonize industrial processes that rely on certain chemical feedstocks or agents. Hydrogen can be used in steel and aluminum production — where its chemical reactivity also helps reduce ore into more useable forms — instead of the currently used coking coal or natural gas. In these industrial processes, hydrogen will be consumed directly as a chemical feedstock in the production process or burned to provide the necessary heat for operation.

Increasing Wind Turbine Waste Will Challenge Nascent Recycling Of Wind Turbine Blades

Wind turbine waste from decommissioning parts will increase in the coming decade as wind turbines installed in the early 2000s reach their end-of-life. By the end of 2010, global wind power capacity reached 180GW, more than 10 times that of end-2000. As much as an increase in wind power means well to reduce carbon emissions from the energy sector, markets globally will soon have to deal with wind turbines that have reached their end-of-life.

Technology trends in the solar inverter space

While central inverters have traditionally been used to convert the direct current (DC) generated by solar power plants, string inverters are now being increasingly dep­loyed across the world. Central inverters differ from string inverters in their ba­sic design. While a central inverter is centrally connected to all solar power mo­dule arrays, a string inverter is a smaller inverter connected to and controlling only a single array or string of solar modules.
