칼륨-나트륨/황 기반 저비용 배터리:
세계 에너지 전환의 중심에는 ‘저장(Storage)’이라는 과제가 있다. 태양광과 풍력은 무한하지만, 해가 지거나 바람이 멎으면 전력이 끊기는 ‘간헐성’이 존재한다. 지금까지는 리튬이온 배터리가 이를 메웠지만, 높은 비용과 자원 제약, 화재 위험성으로 장기 대용량 저장에는 한계가 있었다. 바로 이 틈새에서 등장한 것이 칼륨-나트륨/황(K-Na/S) 배터리다.

There"s no question that American consumers thirst for new products ?as the booming sales of camera phones and plasma TVs attest. But marketers are also noticing a growing demand for products from the past. This trend is affecting everything from cars to candy.

We’ve recently experienced oil price fluctuations that remind us of the economic importance of fossil fuels. But, just how important is petroleum today and going forward? What are the shortterm, medium-term, and long-term trends driving oil prices? What’s likely to happen to oil prices and what are the implications?
