A More Integrated Approach Energy Innovation, Technology & Sustainability

Our Vision To innovate in clean energy, improve the environment, and enhance overall quality of life.

Our Mission To be a highly respected global clean energy company.

We Envision a Clean Energy Future And We Are Making It Happen Today.

The world needs innovative and practical new ways of producing clean energy. ENN is a company that has been working on this fundamental premise for more than 20 years. We have become recognized as pioneers in this work in China, where as a privately owned enterprise we have pursued our vision of making energy use more efficient while enhancing the quality of life for our growing populace. In the process, our quest for new clean energy solutions has evolved, taking us beyond national borders to other parts of Asia, and to Europe and the United States, where we are building collaborative partnerships with others who share our vision. For the reality is that future energy demand has no boundaries: it is a global issue, demanding global collaboration by people with a sense of responsibility for what happens tomorrow. The people of ENN are committed to nothing less than helping reshape a new economics of energy production, distribution, storage and usage. We value and invest in innovative technologies and services and look for ways to integrate them — with each other and within existing energy systems — along with processes that measure their impact. Through these products and services we are demonstrating that we can meet a significant portion of future energy needs through a combination of cleaner energy sources, energy re-cycling and conservation, and advanced energy management and control methodologies. With our valued partners in ever expanding regions of the world, we are working to make this vision a reality today. We invite you to learn about what ENN has already accomplished and then consider collaborating with us on your future clean energy initiatives.

ENN’s Clean Energy Research Center’s Doors are Open Come see what we’re working on!

Not far from Beijing is the city of Langfang, where ENN is headquartered and has established our Energy ENN HEADQUARTERS AND ENERGY TECHNOLOGIES CENTER LANGFANG, HEBEI, CHINA

Technologies Center. Whatever day of the week you may arrive at our building complex, you will find ENN scientists at work in their laboratories. Their research in applied and pure sciences is focused on discovering new ways of producing energy more cleanly, or more efficiently, or more economically. They have come to their positions from some of the world’s most prestigious colleges and universities. Many completed their graduate studies at well-known institutions of higher learning in the United States, Europe and Asia. These laboratories are where ENN is performing gasification research, including underground coal gasification and a low-temperature catalytic coal gasification process designed to reach “zero emissions” by avoiding directly burning coal for energy production. This is where ENN scientists are experimenting with Algal Carbon Fixation, a process of growing enormous quantities of algae that can be used not only to capture carbon but as a source of clean burning fuels. This is where ENN has challenged our elite team of scientists to design and inexpensively manufacture high-performance thin-film photovoltaic solar panel modules that are among the largest and most versatile in the world. And this is where ENN has learned how to combine these and other clean energy technologies and services into integrated, systems-oriented solutions that are tailored to our client’s particular geography, architectural and building requirements, or power generation needs. Until you are able to schedule a visit to see what solutions we’re working on next, the following pages will help to illustrate the scope and impact of our work.

Our Projects Solar Augments Power Plants.

In addition to being adaptable to just about any type of design configuration, ENN’s solar PV technology absorbs and converts light to energy more efficiently under a broader spectrum of light conditions, resulting in up to 15% higher performance in indirect light and high temperature applications. Dr.Deling Zhou Chief Operating Officer ENN Solar Energy TOP Germany’s Masterhausen plant today employs arrays of ENN

Germany is a recognized world leader in installed wattage generated from solar energy installations. Its municipalities and utilities are increasingly embracing solar energy to augment growing power generation demand. ENN is collaborating with several of these already, providing not only project development assistance but also technology and manufacturing capacity to help speed installation timeframes. The most recent collaborations have been in the cities of Neustadt and Mastershausen, which have bolstered energy generation capacity with custom manufactured, ground-based solar array panels made of thin-film photovoltaic silicon.

In addition to being more efficient at converting sunlight to electricity, A team of scientists and engineers from ENN’s Solar Energy Group took the lead in developing these two projects, including project screening, qualification evaluation, financing, production, engineering, installation and connecting the plants to the cities’ electric grids. ENN’s involvement continues after project development to include ongoing monitoring and maintenance of these installations.

modules are manufactured using siliconbased thin-film technology. Thin-film panels have higher performance light absorption properties and the process of manufacturing them results in fewer emissions than crystalline silicon technology. As the name itself suggests, thin film uses less raw silicon — only 1/1000 of silicon product, so the emissions in the production process are minimal.

LEFT In early 2011, the 600KW power

plant near the spa and winter sports center of Neustadt, Germany, augmented its electricity production with an array of 1,000 ENN 5.7 m2 and quarter size thin-film siliconbased solar panels. The solar farm was installed and fully connected to the grid within just two months.

Such a system incorporates a self-organized control and sensor system that employs intelligent routers and terminals and wireless Internet-based communications to integrate and monitor each part of the system. The goal is to fully maximize the efficiency of energy resources in industrial or residential structures to conserve as much energy as possible while lowering carbon emissions.

ENN was incorporated in Langfang, China in 1989. The company began as a successful car rental business. Recognizing an opportunity to make important contributions to the clean energy distribution sector, in 1993 ENN incorporated the ENN Langfang Gas Co. Ltd. with a mission to supply natural gas to downtown Langfang. In subsequent years, the company was successively transformed to focus beyond distribution to research and development in sustainable clean energy technologies and services that have a positive impact on the environment and quality of life for people everywhere.
