Carbon neutrality is when as much carbon as you emit is removed by carbon capture, resulting in zero net emissions. The term carbon neutral is commonly used because carbon-related substances such as carbon dioxide and methane are responsible for most of the greenhouse effect. Greenhouse gases, the main culprits in global warming, make up less than 1% of the atmosphere’s composition. As greenhouse gases have continued to rise since industrialization, the average global temperature has risen by about 1.2 degrees over the past 100 years. The Special Report on Global Warming of 1.5 degrees Celsius, prepared by the IPCC under the auspices of the United Nations, stated that at this rate, global temperatures will rise by about 3 degrees Celsius by 2100, and that a rise of more than 2 degrees Celsius will lead to climate disasters such as heat waves, flooding, and sea level rise. To prevent this, we need to limit the global temperature increase to 1.5﹎ alongside achieving carbon neutrality before 2050, and thus the global and international discussions are spreading.

The world is rapidly transitioning to renewable energy sources such as solar, wind, and fuel cells. This change is being embodied in initiatives such as “RE100,” which calls for companies to source 100% of their energy from renewable sources by 2050, with major countries in the U.S. and Europe, as well as China, jumping on board, expanding the movement. Due to the nature of renewable energy that depends on the natural environment such as sunlight and wind, supply and demand instability is the biggest issue, and ESS is an essential element to solve it. ESS stands for Energy Storage System, a device that aims to improve the efficiency of electricity use by storing electricity generated and delivering it when needed. The key principle is to store excess generated energy in batteries inside the ESS and deliver the stored power at the right time. ESS, which enables the storage and use of renewable energy, has naturally emerged as a core part of the electricity market and is experiencing high growth. Furthermore, the pace of growth is expected to accelerate as Europe offers various incentives to green industries in response to the U.S. IRA and the energy crisis caused by the Russian war. By 2030, the ESS market will be 15 times larger than it was in 2021, according to a Bloomberg forecast.


ACE Engineering’s RE+ Big Rock Ceremony

Building collaborations with the world’s leading energy companies

Held in September, RE+, North America’s largest green energy trade show, is a collaboration between the Smart Electric Power Alliance (SEPA) and the Solar Energy Industries Association (SEIA), two of North America’s leading solar energy organizations, to continually update best practices across the clean energy landscape as the energy market evolves. Since its inaugural show in 2004, Solar Power International has evolved with the green energy industry and is now the largest gathering of green energy professionals in North America, bringing together green energy leaders. While most of the Korean companies attending RE+ 2023 are battery developers, there is one company that specializes in the ESS field that stands out. Starting with challenging the market in 2013, ACE Engineering is a leading domestic company that has participated in various national and private projects and is currently supplying ESS all over the world, including the United States. With more than 40 years of history and tradition, the company provides total solutions for ESS design and manufacturing with technology and know-how as high as the company’s history and tradition. The all in one solution provided by ACE Engineering covers all aspects of the project. All of the company’s products are designed according to the needs of customers and engineered according to the special requirements of different regions, environments, batteries, etc. After that, the company is responsible for production, logistics transportation and installation, and after-sales care. Behind this all-in-one solution is the company’s technical skills.


ACE Engineering is an all-inclusive ESS solutions company

Showcasing at the RE+, North America’s largest green energy trade show

ACE Engineering, an all-inclusive ESS business that spans from design, production, installation to aftercare, showcased its excellence at the RE+, North America’s largest solar, energy storage, renewable energy, and electric vehicle trade show. The RE+ is the largest gathering of green energy technologies in the world, with 27,000 green energy professionals, more than 1,000 exhibitors, and 100 countries represented. ACE Engineering set up its own booth, rubbing shoulders with global companies.


Big Rock Project Ceremony

Aiming to become the number 1 ESS group in the world

ACE Engineering hosted a Big Rock project ceremony within the RE+ event. The event was attended by LS Electric’s U.S. subsidiary LS Energy Solutions, Aventus, and Gore Street Capital. Aventus is the largest solar energy developer in the U.S. with over 20 GWh of energy storage development projects underway, and Gore Street Capital is a UK-based energy storage-focused investment firm with over 1 GW of energy storage in operation. Being able to stand shoulder to shoulder with these companies marks ACE Engineering as a global player. The Big Rock project is one of the largest ESS projects in California, at approximately 480 MWh. The site preparation began in 2023, and the company now aims to be operational by the end of 2024. The Big Rock project is a domestic example of UL9540 certification, a standard used by Underwriters Laboratories (UL), a U.S. safety certification agency, to evaluate the safety of ESS systems and equipment. Certification is based on a comprehensive evaluation of fire and re-ignition hazards and gas and heat release, and UL9540 certification is required for ESS installed in the United States.

ACE Engineering manufactures products for 25 countries, including the U.S., U.K., Australia, and China, with electronics design technology tailored to each country’s safety standards, and this foundation was critical to the successful launch of the Big Rock project. In particular, the fact that the ceremony was held by an ESS system integrator and an ESS manufacturer, as well as an energy developer, shows that ACE Engineering is not just a manufacturer, but a technical partner with its customers. The company has decided to continue to build partnerships with each of the companies that participated in the project, and aims to become the “Global No. 1 ESS” by 2026, with sales of KRW 1 trillion.


Diversifying ESS business and contributing to society

Awarded the Prime Minister’s Citation and the Minister of Employment and Labor’s Citation

Meanwhile, ACE Engineering is preparing to become a global ESS company through RE+, while continuing its various activities both domestically and internationally. In order to diversify its ESS business, the company signed an MOU with Hanwha Aerospace for technological cooperation by participating in the national project ‘Development of Localized Technology for Energy Storage for Ships’. This is collaboration for the standardization of marine energy storage systems, and the purpose is to conduct standardization with Hanwha Aerospace, which is developing modules and systems optimized for ships, as the lack of standards, regulations, and certifications for marine ESS is currently a challenge for technology development.

Along with these efforts, ACE Engineering also contributes to society. In February, ACE Engineering Chairman Insun You donated 100 million won to his alma mater, Korea University College of Engineering, for a 60th anniversary building fund. In addition, the company has contributed to the creation of jobs by developing the scale of its business, while many companies have been inactive in creating jobs due to the global economic downturn. For these contributions, the company was awarded the Prime Minister’s Citation at the SME Management Innovation Competition in 2021 and the Minister of Employment and Labor’s Citation at the 33rd Seoul SME Competition in June last year.
