ENERGY AND MINES CONGRESS REPORT: ONE-STOP SHOP FOR 2020’S BEST INSIGHTS

Last December, Energy and Mines brought together thought leaders from both the mining and renewables industries for their Virtual World Congress. Now, two days of some of 2020’s best presentations and panel discussions are brought together in a single resource volume — E&M’s Conference Report.

Energy and Mines’ latest issue summarizes key takeaways in six separate articles corresponding to the six content pods from the conference. Four offer a regional focus – on South America, Africa, and North America, respectively. One discusses decarbonizing material movement. The remaining two are of course closest to our hearts — Toward Zero Emissions Mining and Optimizing Renewable Energy for Mines. What makes this issue special are the links to recordings from each of the conference presentations, found directly on the pages of the magazine. If you missed the conference last year, now all of its content is available at your fingertips.

In the section Toward Zero Emissions Mining, be sure to take in the discussion of Hybrid Renewables for the Mining Sector – State of Play and Market Outlook, with senior researchers from Wood Mackenzie. And don’t miss 247Solar CEO Bruce Anderson’s presentation on our round-the-clock solar solution for Optimizing Renewables for Mines.

MORE ABOUT HeatStorE™ LONG-DURATION THERMAL BATTERY

Last issue, we introduced HeatStore™, 247Solar’s long-duration thermal battery. Here’s more about what HeatStorE™ is, how it works, and how it offers unique advantages in mining applications.

HeatStorE™ is a low-cost thermal (heat) battery that can supplement conventional electrochemical batteries for long-duration electricity storage, defined as storage of more than 4 hours. That’s important because, for more than a few hours of operation, conventional electrochemical batteries become cost prohibitive. HeatStorE™ batteries offer storage for up to 20 hours or more, at a much lower cost per kWh than conventional batteries. And, completely unlike any other batteries, they can burn hydrogen or other fuels when their thermal storage is depleted for 24/7 dispatchability — eliminating the need for diesel gensets.

WAIT, BATTERIES THAT BURN FUEL?

A battery is simply a storage system that can be charged with, and later discharge, electricity. HeatStorE™ combines two breakthrough inventions that are part of 247Solar’s Ultra-High Temperature Technology Platform: the 247Solar Heat2Power™ Turbine and the 247Solar Thermal (heat) Storage System. Electric resistance coils heat the Thermal Storage using zero/low-cost excess power from PV or wind. As needed, atmospheric-pressure air is passed through the Thermal Storage and heated to extremely high temperature (1000℃/1850℉), hot enough to drive the Turbine and generate electricity — uniquely, without combustion.

24/7 DISPATCHABILITY

If solar/wind energy are unavailable and the thermal storage is depleted, the battery can also produce dispatchable power any hour of the day by burning fuel. This is accomplished by adding an external combustor to the turbine which can burn a variety of fuels, ideally emissions-free fuel such as hydrogen.

HeatStorE™ operates almost exactly like electric batteries, but at lower cost, and offers significant benefits to miners.

  • Complements other power technologies to balance power supplies with fluctuating loads
  • Increases system reliability
  • Increases system versatility
  • Strengthens system resilience • Provides supplemental, 24/7 standby dispatchable power
  • Eliminates need for costly, dirty gensets
  • Can supply useful heat up to 1000℃/1850℉

The accompanying illustration shows the basic layout of a single 1MWh HeatStorE battery. Multiple HeatStorE batteries can be combined to achieve any required capacity. Contact us and we’ll tell you more.
