6 FAQs about [Lake bottom cold water energy storage]

How does a deep lake water cooling system work?

The deep lake water cooling result is less energy consumption than other sources and significant reductions in water consumption. The system is so successful that it saves the city 90,000 mega-watt hours of electricity use annually, which can be equated to the energy needed to power a town of 25,000.

How much energy does a deep water lake cooling system save?

The deep water lake cooling system features prominently in the TransformTO plan, as it already saves 90,000 mega-watt hours of electricity use annually — roughly enough to power a town of 25,000. Energy savings are about 90%, and, as the required cold water is available year-round, the need for supplementary chilling is eliminated.

Is a deep water lake cooling system a good idea for Toronto?

GHG emissions in Toronto were 38% lower in 2019 than in 1990. The deep water lake cooling system features prominently in the TransformTO plan, as it already saves 90,000 mega-watt hours of electricity use annually — roughly enough to power a town of 25,000.

Why are lake water storage projections limited?

Lake water storage projections are limited primarily by the absence of reliable, long-term, homogenous and spatially resolved hydrologic observations necessary for building lake water budgets and for assessing the validity of climate models 100.

How does air temperature affect lake ice break-up?

The timing of lake ice break-up is generally governed by air temperature and its attendant effects on other components of the surface energy balance, primarily net radiation 16, 22, 23.

What is deep lake water cooling (dlwc)?

Or follow us on Google News! Deep below scenic Lake Ontario’s surface is Toronto’s most valuable source of renewable energy — cold, cold water. Since water is densest at 39°F (4°C) and sinks to the bottom, it can become a stable chilled water source for deep lake water cooling (DLWC).
