Ice Energy Launches Solar + Ice: Solar Electricity with Thermal Energy Storage
Energy storage plays a big part in the transition from last-century fuels to renewables, and some consider it a kind of Holy Grail when it comes to a sustainable energy future. People got very excited lat spring when Tesla unveiled their new battery storage system, the Tesla Powerwall. But aside form lead acid or lithium ion batteries, what other options are there for storing power when more is being generated than used?
Ice energy, a company that provides thermal energy storage solutions, is now offering utility-scale solar PV that will freeze water when power needs are lowest and then use the ice to cool air instead of powering A/C compressors, making for a much more efficient system.
“Currently available batteries are expensive, wear out and their chemicals create disposal issues,” Mike Hopkins, Ice Energy CEO, said. “In contrast, energy storage using ice is the greenest, most cost-effective method to integrate renewables into the grid and is truly worthy of solar.”
Deployments of solar-plus-storage nationwide are expected to jump from 4 megawatts in 2014 to 22 megawatts this year, according to research conducted by Greentech Media. By 2020, the market is projected to be worth $3.1 billion with deployments of 769 megawatts.
