中国与美国合作太阳能微型智能电网"


当美国总统奥巴马å'Œä¸­å›½ä¸»å¸­ä¹ è¿‘平在2014å¹´11月宣布ä»-们将致力于削减碳æŽ'放,很少人认为会迅速发生变åŒ-。

不到两个月后,中国æ¹-北襄阳研究院(XYI)å'Œç¾Žå›½æ-°å¢¨è¥¿å“¥å·žçš„拉æ-¯å…‹é²å¡žæ-¯çš„Focused Sun,在太阳能微型智能电网的重要领域上开始合作。微型智能电网是为封闭的社区,购物中心,生态度假村å'Œå†œä¸šé¡¹ç›®ä¾›åº”能源的小型局部电网。

XYI院长陈继红说,"Focused Sun通过聚焦太阳光,已经压缩了太阳能集中器、微型电网系统关键部分的成本。与蓄热器å'Œä¸­å›½æ¶¡è½®å¼å‘电机结合,我们可以制造微型智能电网小型发电厂"。

反射太阳能加热矿物油至现代涡轮式发电机所需的温度"”"”300摄氏度。蓄热器保存热量一天æˆ-更长时间,可以在白天æˆ-是夜晚发电。

"太阳能的高峰是在中午,但人们在晚上需要热能å'Œç”µèƒ½,"éº»çœç†å·¥å­¦é™¢æ•™æŽˆï¼Œè“„热器å'Œæ¶¡è½®å¼å‘电机专家,大卫·戈登·威尔逊说。威尔逊认为蓄热器可以一直为发电机提供动力,直至第二天。

"对于100千瓦至10兆瓦范围的微型智能电网,低成本的太阳能集中器å'Œè“„热器同涡轮发电机结合比光伏集电极å'Œè“„电池储能更有意义。蓄热器是被遗漏的关键要素,"ä»-说。

相同大小的太阳能集中器可以比传统的光伏面板多吸收四倍甚至更多的太阳能。在白天,太阳能以热的形式储存。在晚上æˆ-阴天时,存储能量注入到涡轮发电机,这其中20%的能量转换为电能。剩下的50%的太阳能量可以变为热量,例如使住宅、é…'店房间å'Œæ¸©å®¤æ¸©åº¦å‡é«˜ã€‚

这个系统产生电å'Œçƒ­æ°´,可以供其自身使用两年。Focused Sun集中器是由当地生产的,为当地带来就业机会å'Œä¾¿å®œã€æ¸…洁的能源。每花一美元,就收集四倍的太阳能。

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
