Innovative Solutions to California's Water Crisis
In response to California's dire water shortage, a startup is venturing into advanced desalination methods. This technology, focusing on the depths of the ocean, could significantly alleviate the ongoing drought challenges faced by the state.
Water technology company OceanWell is pioneering the development of subsea desalination pods that have the potential to convert saltwater into potable water on a large scale, offering vital support for areas under severe water stress.
Urgency of Global Water Scarcity
Globally, over a billion people lack access to safe drinking water, as estimated by the World Health Organization. Moreover, half of the population experiences some level of water scarcity throughout the year. It's anticipated that by 2030, an estimated 700 million people could be displaced due to drought, which has led to intensified conflicts over water resources, particularly in regions like Syria and Sudan.
"Water is essential for all life and is the most widely used commodity globally. A person can't survive without it for three days," said Robert Bergstrom, CEO of OceanWell, emphasizing the critical nature of their work.
Based in Los Angeles, OceanWell is collaborating with the local water district to roll out its first commercial water farm, set to be operational by 2028. This area was chosen due to its recurring drought issues, diminishing groundwater reserves, and dependence on external water sources from the Colorado River.
How OceanWell's Pods Function Under the Ocean
Traditional desalination processes involve reverse osmosis, which forces seawater through membranes under high pressure to remove salt and impurities, yielding drinkable water along with a brine byproduct. Such methods are essential, especially considering that many countries like Saudi Arabia and the United Arab Emirates rely heavily on desalinated water for their supply.
OceanWell's innovative approach utilizes the natural pressure of ocean water to facilitate reverse osmosis, potentially reducing energy consumption by up to 40% compared to conventional onshore desalination facilities. Each pod is capable of generating a minimum of one million gallons of freshwater daily, and combining multiple pods could create extensive water farms capable of supplying entire cities.
Unlike typical desalination plants that need substantial onshore infrastructure, OceanWell's subsea pods remain unobtrusive, maintaining the integrity of coastal landscapes and ecosystems. The company also highlights that their pods demonstrate climate resilience by being shielded from floods, harmful algae blooms, and severe weather conditions due to their underwater location.
Addressing Environmental Concerns and Future Growth
One major concern surrounding desalination is related to concentrated brine being harmful to marine life when returned to the ocean. OceanWell's technology mitigates this issue by releasing water that is only slightly saltier than the surrounding sea, allowing it to disperse without adverse effects. Their LifeSafe system is designed with marine conservation in mind, ensuring that marine organisms remain unharmed.
"We are committed to leaving marine ecosystems intact, and we ensure that we do not alter any conditions that marine life depends upon," Bergstrom states, reinforcing their dedication to environmental considerations.
Founded in 2019, OceanWell currently employs a team of 13, having raised approximately $14 million to date. With plans for an upcoming funding round, they aim to expand their capabilities significantly. Their goal is to contribute an impressive 1.2 billion cubic meters of sustainable freshwater to the global supply within the next decade.
"I chose to work in water nearly three decades ago after observing the impending crisis. Our path forward has been challenging, but we are making progress," Bergstrom reflects on the mission underpinning OceanWell's innovation.
