The African Development Bank will finance $25 billion by 2025 to support Africa's fight against climate change, the bank's president said at the bank's annual meeting in Accra, Ghana.  

He noted that climate change has had many negative impacts on the continent, causing natural disasters such as droughts, cyclones, and floods. Climate change costs Africa between $7 billion and $15 billion a year. "Africa has no choice but to address climate change."  

To ensure Africa's food supply, the African Development Bank has delivered climate-friendly seeds to 12 million farmers in 27 countries in the past two years under the "Technology for Agricultural Change in Africa" program, he said.  

In the area of renewable energy, the African Development Bank is implementing a $20 billion "Desert Power" initiative in the Sahel that is expected to power 250 million people, he said.  

US President Joe Biden recently wrapped up his five-day trip to Asia with a summit of leaders of the "Quad" security Dialogue.  

Biden has promoted a number of economic and security cooperation initiatives during his visit aimed at deepening ties with Indo-Pacific Allies and partners in response to China's growing influence in the region. Some analysts in the United States believe the most significant announcement may be an initiative to share maritime information to combat illegal activities. But other experts say Biden's move sets a good framework for more security cooperation, though it remains to be seen whether concrete action will follow.

Affected by several factors, the supply of the silicon carbide powder is erratic and thus its prices are expected to go higher in the future.

What is Silicon Carbide SiC?
Silicon carbide (SiC) is a hard compound containing silicon and carbon. A semiconductor, it is found in nature in the form of the extremely rare mineral moxanite. 
It has been mass-produced in powder and crystal form since 1893 for use as an abrasive.  Silicon carbide particles can be sintered together to form very hard ceramics that are widely used in applications requiring high durability, such as ceramic plates in car brakes, car clutches, and bulletproof vests. Large silicon carbide single crystals can be grown by the Lely method, and they can be cut into gemstones called synthetic mossanes. 
 
What can Silicon Carbide Devices Bring to New Energy Vehicles?
Silicon carbide power devices have been used in critical power systems inside electric vehicles, including traction inverters, on-board chargers (OBC), and DC-DC converters.  Key advantages over traditional silicon devices include higher voltage and higher frequency features, resulting in higher system efficiency, faster switching, lower losses, and better thermal management. Compared with silicon-based devices, silicon carbide devices have the following advantages:
 
Lift acceleration 
The use of silicon carbide devices can make the driving motor bear more input power at low speed, and because of its high thermal performance, not afraid of the thermal effect and power loss caused by excessive current. When the vehicle starts, the driving motor can output more torque and obtain stronger acceleration ability. 
 
Increase mileage 
SiC devices can reduce the loss through two dimensions of conduction/switching, so as to achieve the purpose of increasing the range of electric vehicles. The results show that the turn-off loss of sic-MOS is about 20% of that of Si-IGBT at 25°C junction temperature. At 175°C junction temperature, the turn-off loss of sic-MOS is only 10% of that of SI-IGBT.  In general, the use of SiC devices in new energy vehicles can increase the driving range by 5-10%, and the average driving range is more than 600 kilometers. 
 
High rated voltage 
Silicon carbide MOSFET has a higher voltage rating, making the technology suitable for EV applications and EV quick charging infrastructure. More importantly, the SiC can be replaced directly without major changes, enabling rapid development while keeping the BOM low. 
 
Lightweight 
To achieve lightweight thanks to the superior performance of SiC, SiC devices can achieve the effect of reducing the volume in the following aspects: 
1, the package size is smaller, and the average weight is reduced by 150 to 200 kg; 
2, reduce the use of filters and passive devices such as transformers, capacitors, inductors, etc.; 
3, reduce the radiator volume. 
 
Economical
At present, the price of SiC devices is 4-6 times that of silicon based devices, but the use of SiC devices to achieve a substantial reduction in battery cost and the improvement of the range, reducing the overall cost of the vehicle.
 
Silicon Carbide Price
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

With the outbreak of the Russia-Ukraine conflict, the market is increasingly worried about the potential disruption of Russia's energy supply. Geopolitical premiums have pushed up the price of crude oil and natural gas, and the energy price is expected to remain high in the short term. Affected by this, the market price of the silicon carbide powder may continue to rise.
