조태용 대사 "미, 한국 전기차 차별 부당"

VOA

2022.8.30

미국의 인플레이션 감축법(IRA)에 따른 한국산 전기차 문제의 해법을 찾기 위해 미한 정부가 협의를 갖기로 했다고 조태용 주미 한국대사가 밝혔습니다.

한국 언론에 따르면 조 대사는 29일 워싱턴에서 “우리는 자유무역협정(FTA) 파트너인 한국의 전기차에 대한 차별적 조치가 부당하다는 점을 강조했고, 미국 측은 별다른 이견을 제시하지 않았다”고 말했습니다.

조 대사는 “이러한 논의를 바탕으로 한미 양국 정부가 이 문제에 대한 해결책을 마련하기 위해 정부 간 회담을 갖기로 합의했다”고 덧붙였습니다.

From TechXplore:

Institute demonstrates first-of-its-kind small-scale pumped heat
energy storage system

by Southwest Research Institute
August 30, 2022

Southwest Research Institute (SwRI), in partnership with Malta,
Inc., has completed assembly and commissioning of the
first-of-its-kind pumped heat (or thermal) energy storage (PTES)
demonstration facility. Long-duration, large-scale storage
capabilities, like PTES, can help balance energy volatility and
reliability issues caused by high market penetration of variable
renewable energy resources such as solar and wind energy, and
create solutions to fulfill worldwide carbon reduction goals.

"One of the big problems that we face with renewable energy is
balancing supply and demand," said SwRI Group Leader Dr. Natalie
Smith, the project's lead investigator. "As the sun goes down in
the evening, many people are returning home from work, turning on
lights and using other electronics. This mismatch between high
power demand and solar availability creates grid volatility. We
want new technologies to store solar and wind power so that it
can be used when the sun isn't shining, and the wind isn't
blowing."

A PTES system stores energy thermally in hot and cold tanks for
later use. When excess wind or solar energy is being produced,
the PTES runs a heat pump to make the hot storage tank hotter and
the cold storage tank colder. Then, when energy demands exceed
production, the PTES runs as a heat engine converting the large
temperature difference between the hot and cold stored energy
into electricity.

"The full-scale PTES system offers high potential system
performance up to 60% round-trip efficiency and can store energy
for more than 10 hours," Smith said. "PTES is a promising,
versatile technology that can be applied to many different energy
sources without geological or geographical restrictions."

Malta, Inc. is developing a full-scale commercial PTES system
capable of storing energy for more than 10 hours. Under
DOE-funding, SwRI developed a small-scale PTES demonstration
system that uses simple recuperated cycles for both modes of
operation with air as the main working fluid. The facility design
is similar in basic architecture and operation to the full-scale
technology and is intended to demonstrate system operability and
controls strategies.

The U.S. Department of Energy supported the development of the
system, which was successfully commissioned and has begun the
detailed testing phase.

"We are hoping that this successful demonstration provides more
confidence in this technology," Smith said. "PTES provides a
viable means to bring balance and stability to our energy usage.
If we want to reduce carbon emissions, we need to integrate more
renewables. Our demonstration is the pathway to that full-scale
system and demonstrates commercial readiness."
