Solar generated electricity, which can suffer from intermittency issues and related impacts on the grid, is about to blossom at Arizona State University. Work will now begin on the development of a hybrid concentrated solar system, following a contract signing with ASU and AORA to provide research expertise in order to enhance the efficiency of this unique technology.

AORA Solar NA, has agreed to install the first ever Solar Tulip hybrid generating facility in the United States on university land, and ASU faculty, research staff, and students will work hand in hand with AORA to enhance the system.

This project includes the installation of a hybrid concentrated solar power plant that employs a Solar Tulip to concentrate the sun's energy, turning it into electricity. The system produces power 24/7, moving seamlessly from solar to natural gas or biogas and is also promising because it uses little to no water while producing a high quality thermal output in addition to power.

AORA Solar NA, a U.S. company, will work with a multi-disciplinary ASU team to research options to increase efficiency, improve reliability, utilize the exhaust heat and decrease the cost of this Israeli developed technology. AORA will construct the demonstration power plant, which includes a tower (approximately 100 feet high) appropriately called the Solar Tulip, on undeveloped land near the Karsten Golf Course in Tempe.

The technology includes a collection of mirrors to concentrate the sun's rays to heat compressed air to more than 1800 degrees Fahrenheit and drive a gas turbine. The rated output of the Tulip system is 100 kilowatts of electricity and an additional 170 kilowatts of thermal energy, about enough energy to power between 60-80 homes.

At night, or when overcast, the Tulip can use a wide range of fuels to heat the air and is thereby able to produce power and heat round the clock. The system is modular in design, allowing for multiple Tulips to work together, enabling the technology to match growing electric demand requirements.

The relatively small footprint makes this system a potentially perfect complement to housing developments, or industrial parks, and offers an option to enhance grid stability in the presence of transient renewable generation.

"ASU is a natural partner for us, not only because of its sunny location, but because of the university's dedication to innovation and sustainability," said Zev Rosenzweig, CEO of AORA Solar.

"We are excited to make our debut here in the United States with this innovative technology where we will continue to grow and develop the Tulip into a system that cities and industries around the world use to generate continuous energy with renewable resources. ASU's breadth of research capability will undoubtedly allow us to increase output, and reduce overall costs which will bring us to commercial viability.

Our confidence in this project is enhanced with the participation of Project Director, Ellen Stechel, who has spearheaded the concept from the beginning, along with her colleagues Gary Dirks, William Brandt and the ASU LightWorks team."

AORA Solar is currently operating two additional research facilities, one located in a solar research park in Almeria, Spain, and the original unit in Israel. These systems can be controlled remotely via computer, a unique capability that provides innovative options for possibilities in the U.S. and indeed around the world, including developing countries.

The ASU/AORA collaborative relationship will not only bring ASU closer to its goal of becoming carbon neutral by 2025, but it will also benefit students and researchers across multiple fields of study.

"This is another instance in which ASU has brought in cutting edge technology that its students can learn from and help perfect," said Sethuraman "Panch" Panchanathan, senior vice president of Office of Knowledge Enterprise Development at ASU. "With this collaboration, the university has established a commitment to integrate students, faculty, and staff into research on the Solar Tulip design to bring 24-hour solar/renewable technology to commercialization."

"The AORA/ASU collaboration provides a multitude of possibilities looking forward," said Gary Dirks, director of ASU LightWorks.

"It is a perfect example of industry and academia coming together and leveraging their unique strengths to create collaborative projects that propel new and viable technology into our energy future. The Solar Tulip has enormous potential both at ASU and beyond."

AORA Solar has contracted with GreenFuel Technologies, a Phoenix-based General Contractor specializing in environmental energy projects to construct the research plant at the ASU campus. Groundbreaking is expected to occur in April, with the anticipated operation date to be sometime in the late September/early October time frame. AORA Solar and ASU look forward to welcoming university peers along with the public to a ribbon-cutting event at the Tulip's completion.

"We are pleased to host the Solar Tulip at the ASU Tempe campus," said John Riley, sustainability operations officer at ASU. "It is a visually iconic piece of technology, helping to illustrate the way ASU is a destination place for state-of-the-art research and facilities."

This collaboration was advanced by Arizona State University LightWorks, a research initiative that unites resources and researchers across ASU to confront global energy challenges.

The LightWorks team provided the vision of required research, identified the multiple research windows in which AORA will participate and is intimately involved in moving the project from concept to fruition. With a proven track record of swiftly and strategically partnering with a diverse set of institutions, LightWorks continues to help overcome challenges in the fields of solar power, sustainable fuels, and energy policy.
