A competition for water-related clean tech startups, Imagine H2O, announced its 2010 finalists today. The competition focuses on water startups that save energy, especially in the areas of sourcing, distributing, treating and disposing of water.
Sure, oil and water don’t mix. Neither do electricity and water. There’s still a serious connection between energy and H2O. We use huge amounts of power to get our water, and vice versa.
According to the American Council For An Energy Efficient Economy:
“Water and wastewater treatment and distribution in the United States is estimated to consume 50,000 GWh annually, representing 1.4 percent of the total national electricity consumption, and cost over $4 billion each year.”
Further research by the River Network found:
“On average, two gallons of water is consumed for every kilowatt of electricity used in the United States. This means that 170 gallons are used to run the clothes dryer, 55 gallons are used to run the computer and 73 gallons of water are used to run a TV in a typical American household every month.”
At utilities and in the home, where consumers use a significant amount of energy to heat their water, reducing water consumption almost always leads to lower costs, reduced energy consumption and less air pollution.
Imagine H2O seeks to halt a widely anticipated global water crisis, but also views global water problems today as an estimated $500 billion market opportunity for providers of water products and services.
In 2009, Fruition Sciences took the Imagine H2O grand prize for a system that monitors vineyards with wireless sensors, weather stations and software, ensuring that vines are irrigated efficiently, leading to optimal berry (or grape) yields.
The Fruition Sciences website explains:
“[The company's] real-time sensors [are placed on vines, and] send a wireless reading of a vine’s transpiration rate, providing a precise measurement of how much water is moving through the vine…This gives an indication of the vine’s water needs. A slow rate of transpiration indicates a vine is low on water (stressed) and potentially at risk of berry dehydration.”
This year’s IH2O grand prize winners will receive at least $20,000 in cash, $15,000 of in-kind legal services and the same amount in consulting services. IH2O’s second and third place winners will each receive at least $10,000 in cash, $7,500 of in-kind legal and the same amount in accounting services. They will be chosen by and announced in March 2011.
A list of the contenders, with company-provided descriptions, follows below:
