The Next-gen Solar Thermal Tower Heliostat with Molten Salt Thermal Energy Storage Option

 Solar Thermal TowerBURBANK, Calif. eSolar®, a leading developer of modular, scalable concentrating solar power (CSP) technology, unveiled two innovative new product offerings in 2013.. This news comes on the heels of eSolar’s $22 million funding tranche to support expansion into the Middle East and North Africa, where the company’s technology can generate steam for enhanced oil recovery (EOR) operations as well as desalination and industrial process heat applications.

“We’ve made the case for our small, factory-built heliostats in high-density solar fields around the world,” said John Van Scoter, CEO of eSolar. “Today, we’re raising the bar with our reimagined SCS5 design, which promises to significantly improve project economics for the global CSP market.”

This scalable solution can be implemented for peaking power plant applications through large baseload plants, and with minimal scale-up risk. Additionally, thanks to a modular design, power towers can be easily replicated at project sites to create plants as large as 200 MW with up to 75-percent capacity factor. This means storage enables the plant to deliver its full power output 75 percent of the time compared to typically less than 30 percent for systems without storage.

“In addition to enabling firm power on-demand, our molten salt plants also allow system operators to reuse produced water from oilfields, which creates a particularly attractive offering for the solar EOR industry, even in a 24/7 operating configuration,” continued Van Scoter.

About eSolar

eSolar was founded in 2007 to develop modular and scalable solar thermal power plant technology. The eSolar solution marries a low-impact, pre-fabricated form factor with advanced computer software engineering yielding break-through cost reductions for the solar collector system. eSolar’s highly efficient power tower design meets the demand for reliable, dispatchable and cost competitive solar power, and is well-suited for non-power generating markets, such as enhanced oil recovery, water desalination and industrial process heat applications. eSolar is based in Burbank, California.

  • VULVOX Inc’s breakthrough collectors will be able to generate more power than generated by current solar power tower plants! The Abengoa solar power tower is currently the worlds biggest. If it is retrofitted with VULVOX hybrid solar energy collectors it will generate 46.5 megawatts, not 20 as it does currently. Our breakthrough design will also add 50% to the electricity generated by Stirling dishes.
    The dual solar thermal-photovoltaic system will wrest approximately twice as much power from an area as regular solar thermal or photovoltaic energy systems. Our technology can be used to retrofit existing parabolic troughs and solar power towers to increase their efficiency.

    The Vulvox collectors will not depend upon complicated advances in quantum or solid state physics. Our novel combination photovoltaic-solar thermal collectors will achieve the unprecedented efficiencies predicted here by means of relatively simple modifications to solar energy equipment; modifications that can be developed at a moderate cost. The Vulvox solar system will generate higher power levels than competing parabolic troughs and solar power towers, while retaining all of the storage capabilities of solar thermal power.

    Every time a commerically available photovoltaic panel system is upgraded and increases in power we can substitute it for a lower power panels used in previous “builds.” and the higher power panels can be used in upgraded combination PV-solar thermal collectors with higher efficiency. Also, every time solar thermal systems are upgraded they can be combined with the latest practical photovoltaic collectors to keep the next generation combination systems cost competitive and to keep their efficiency higher than all other collection systems.
