Carbon Capture in the Southeast Asian Market

In recent years, Carbon Capture Utilization and Storage (CCUS) discussions have gained traction in Southeast Asia (SEA). With the technology-intensive nature of CCUS, several countries could provide reference points for the CCUS potential in Asia: China, Japan, and South Korea. All three countries have a long history of technology leadership and energy investments in the region. Their experiences with CCUS can provide a glimpse into the future path of CCUS in SEA.

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.

Automation Era: Digital solutions set to transform the wind sector

Digitalisation presents several advantages to wind energy systems in terms of improved safety, greater reliability and accuracy in data collection, spee­dy dissemination of data, lower operatio­nal cos­ts and greater flexibility in undertaking ma­in­tenance activities. The development of digital technologies for operation and ma­in­tenance (O&M) has given rise to new business models in the energy sector due to redu­ced dependence on hu­man interventions.

Finding the right battery technology for long-duration storage

The emergence of iron-based chemistries to solve some of the cost issues of RFBs is expected to improve their commercial feasibility, allowing them to compete with lithium-ion for around half of the stationary storage market by 2030, according to the US Department of Energy’s Energy Stor­age Grand Challenge Market Report 2020. Currently, the preferred electrolyte for flow- batteries is vanadium due to its stability.

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.

Big data: The energy revolution in US no one is talking about

The big data revolution is already changing many industries in America. Recently, New York began testing how much value it can create by expanding energy data access. In doing so, New York may be leading a long-anticipated revolution in how utilities, developers, and customers can access, use, and monetize data to unlock more value. As the New York data access proceeding evolves, it serves as an industry case study for regulators, developers, and utilities around the country.

Assessing Europe’s Future Flexibility Needs: ENTSO-E releases position paper 

Under the Fit-for-55 package, the EU-level target for renewable energy is proposed to be increased to at least 40 per cent by 2030 (from 32 per cent previously) along with introduction of sector-specific measures for increasing its contribution to the final energy demand. This indicates the need for an accelerated renewable energy deployment. For instance, the EU will need 451 GW of wind capacity by 2030 (up from about 180 GW in 2021) and will have to double its planned annual capacity addition in the coming years.

Storing for the Future: Role of CCUS in low carbon development in ASEAN

In ASEAN, CCUS could be fundamental in helping the region decarbonise   energy   systems   from   coal-based   electricity   generation and in achieving the net-zero target. Some AMS have  expressed  interest  in  deploying  CCUS  technologies  in  their   countries.   However,   none   has   established   specific   measures or an action plan, such as policy support from governments towards the energy transition and low-carbon economy through CCUS development.

Disruptive clean energy technologies for APAC’s energy security

Disruptive technologies have emerged in the renewable energy and energy efficiency sectors which have rapidly changed the global energy landscape. Disruptive technology is defined as a technology, which creates a new business model that could disrupt a traditional business model. These disruptions generate a revolution in technology capability, digital transformation, cost, new business model, and change of policy. A number of energy-related technologies have become the game changers of energy demand and supply in APEC region and the world.

Technology Advancements To Lower Solar Power Costs Over Long Term

The cost of solar power has declined significantly over the past decade, with the Levelised Cost of Energy (LCOE) for solar falling from a weighted average of USD378/MWh USD248/MWh in 2010 to USD68.4/MWh in 2019. According to financial advisory and asset management firm Lazard, the LCOE for utility-scale solar power reached USD36/MWh in 2021. The steep decline is the result of several factors including a rapid decline in module costs, increased competition, and economies of scale from significant growth globally.

Assessing the potential of offshore renewable energy in Africa

How can the ocean contribute renewable energy to the African ‘Blue Economy’, bringing opportunities to millions of Africans and reducing or replacing carbon emissions, and which strategic actions can help it reach this potential? The power quality of offshore renewables is relatively high, being more predictable and less variable than many other renewables. The results indicate that coastal Africa, according to available data, has high technical potential for all offshore renewables, apart from tidal stream power.

Resource adequacy recommendations for a clean energy grid in the US

The controversial topic of resource adequacy (RA) is undergoing fundamental reassessment to function properly with the future resource mix. From a legal standpoint, while FERC’s authority over resource adequacy in the ISO/RTO setting has been construed expansively, the Commission has declined to mandate capacity markets in circumstances where reliability and economic problems have not been demonstrated.

Advantage Africa: Low cost of producing lithium-ion battery precursors in the DRC

The objective of study is to determine the cost of producing lithium-ion battery precursors in the Democratic Republic of Congo (DRC) and benchmark the cost to that of the U.S., China and Poland. In addition to the cost, the study assesses the emissions associated with the production of precursors in the DRC for the global electric vehicle market compared with producing them in China and Poland. Building a 10,000 metric-ton precursor facility in the DRC could cost $39 million. This is three times cheaper than what it would cost for a similar plant in the U.S.
