solar power use24/7 on demand

How can solar power become a 24/7
on-demand energy source to decarbonize and power industry?

 

Renewables alone won’t reliably power the energy transition. Fully replacing fossil fuels calls for an increased security of renewable energy supply from Concentrated Solar Power (CSP), Concentrated Solar Thermal (CST), Wind Energy and Photovoltaics (PV). Already today, CSP allows for energy storage as an integrated part of the plant, enabling on-demand dispatch of electricity or heat and steam during peak hours, or even 24/7 baseload operation.

 

Our thermal energy storage solution provides a affordable, reliable and cost-efficient storage technology for industrial manufacturing processes and CSP and CST plants. It is perfectly tailored for parabolic trough plants and direct steam tower- and linear Fresnel plants. Plugged into both systems, ENERGYNEST’s ThermalBattery™ stores and recycles thermal energy from solar into low-cost green electricity, heat, and steam ‒ on demand. ENERGYNEST increases the reliability of solar thermal energy and therefore security of supply, whilst substantially reducing energy storage costs, energy losses and carbon footprint – especially compared to conventional storage with molten-salt systems.

Our applications for your industry

Whether you are a new plant developer looking to substantially reduce your energy storage costs and submit competetive bids in tenders or plug it to industrial parks or heat and steam consumers, or you are a existing plant owner looking to retrofit your plant to reduce energy losses and sell more electricity during peak hours: thermal energy storage is your solution.

 

Compared to conventional energy storage in molten-salt systems, it comes at a much lower CAPEX and lifetime OPEX, largely due to low-cost materials, its system simplicity and no need for specialized operation or maintenance personnel. ENERGYNEST’s ThermalBattery™ provides a non-corrosive environment and eliminates the need for dedicated pumps, heat exchangers and electrical heat tracing for CSP and CST. ‘

Already today, Concentrated Solar Power (CSP) allows for energy storage as an integrated part of solar plants, enabling on-demand dispatch of electricity or heat during peak hours, or even 24/7 base-load operation. However, current thermal energy storage solutions such as molten salts limit the scaling and long-term economic viability of such systems. Our technology offers a better solution. A key lever to realize affordable and reliable energy storage, it also comes at a lower CAPEX and OPEX. Storing thermal oil and turning it to power on demand is the technology of choice to enable the most cost-effective utilization of CSP assets: Increasing CSP flexibility and output, and lowering total costs.

Application Benefits

  • Decarbonize heat immediately
  • Save money easily
  • Reduce maintenance effort
The sun has incredible power. Especially south of the 45th latitude, Concentrated Solar Thermal (CST) power using parabolic through-systems will be among the cheapest technologies to produce carbon-free industrial process heat. But without storage, customers are left with a cold dark night ahead when the CST plant does not produce anymore, but process heat and steam is needed. Storing solar thermal as steam is the technology of choice to best utilize CST assets, recycling excess energy for steam production – enabling true decarbonization.

Application Benefits

  • Decarbonize heat immediately
  • Save money easily
  • Reduce maintenance effort
  • Limit energy market exposure

Retrofit project under development with payback of less than 3 years

ENERGYNEST is evaluating a project for a full-scale retrofit ThermalBattery™ integrated in a parabolic trough plant in the Middle East with highly attractive economics. The installed system offers a cheaper and safer storage system than molten salt, at a much lower cost. The ThermalBattery™ can be used for morning start-up of turbine and also prolonged generation during sunset, boosting electricity generation by almost 10%.

 

The ThermalBattery™ system requires no heat tracing and no oil-to-salt heat exchanger, has near-zero parasitic loads, and requires no extra crew for operation. By producing night-time gland steam for the turbine, there is no affecting day-to-day operations. Thanks to its implementation and demonstration at full scale, the ENERGYNEST thermal storage has the potential to significantly improve the plant owner’s competitiveness in future project bids.
