Cristina Aleixendri Muñoz
Cristina Aleixendri Muñoz always wanted to be a doctor. “I thought the only way to do good in the world was to save lives,” she says. But a chance conversation with a teacher who suggested engineering changed her path.
Muñoz became an aeronautical engineer, working on planes and space shuttles before pivoting to the maritime industry. That aerodynamic expertise helped when she launched bound4blue with her co-founders. The challenge was to overcome the shipping industry’s fuel-consumption problem – shipping alone accounts for 2.5 per cent of the world’s carbon emissions.
“I think engineering can help solve today’s hardest problems, make sustainability profitable and be something that can be developed and implemented,” says Muñoz. The company has developed a wind-propelled eSAIL that can reduce emissions by up to 40 per cent, and which it has tested on three ships. “The intention is for around 80 per cent of the global fleet to benefit from this type of solution,” she says.

Liane Thompson
As a journalist for The New York Times, Liane Thompson used to travel the world. Once, while she was in South Africa, she reported on an entrepreneur called Simeon Pieterkosky. Little did she know then that she would reconnect with Pieterkosky around a decade later in 2014 to develop Aquaai.
The husband-and-wife’s marine-robotics company builds affordable Autonomous Underwater Vehicles (AUVs), which it calls Nammu. These are shaped like fish and are used to gather environmental data deep underwater, without intruding on the marine life living there. The AUVs are 3D printed and come installed with off-the shelf cameras and sensors – deliberately so, says Thompson, so that people can build their own in communities that need them most.
And that need is ever increasing, says Thompson, “given superstorms, floods, the proteins and food sources coming out of underwater farming, and the need to protect marine habitats and corals.”

Ido Sella
Marine biologist Dr Ido Sella has been fixated on the impact of coastal construction on the marine environment for more than 20 years. His bugbear? Concrete, as it doesn’t support the same biodiversity as other substrates. In an ideal world, natural reef would mark out ports and create promontories – but that won’t happen. So Sella worked to develop a material that would be better than the concrete used in 70 per cent of coastal infrastructure.
And so, in 2012, ECOncrete was born. A decade ago, the company started experimenting in the Mediterranean and the Red Sea. The findings were shocking: the mix itself was an issue, as was the surface and the structural strength. ECOncrete solves all three problems: its Admix can be added to regular concrete to provide a better chemical balance for marine life, its texture agents help marine life cling to the structures and their moulds help create ecological niches and strengthen the structures.
ECOncrete is now used in breakwaters and ports globally. “There is a real drive from the industry to look for these solutions,” says Sella.
Co-founder, Coral Vita, Freeport
Sam Teicher
At the age of 13, Sam Teicher gained a scuba- diving certification. “I’ve loved the ocean and nature my whole life,” he says. “As a kid from Washington, DC, I grew up imagining I was going to become a coral farmer.” Teicher studied the environment and climate change in college, then grad school. It was through working at a friend’s NGO between courses that he was first introduced to coral restoration – and it became his life’s work.
Coral Vita, the company Teicher co-founded in 2019, grows coral 50 times faster than it would grow in nature – so it can be replenished as modern life diminishes our reserves of the natural resource. Started with a $1,000 grant from Yale, where Teicher and his co-founder met, Coral Vita is now behind the world’s first commercial land-based coral-reef farm, in Freeport, Grand Bahama, where the coral
grown is being used to replenish the reef. In 2021, the company won Prince William’s inaugural Revive Our Oceans Earthshot Prize. “We hope to kick-start the whole restoration economy,” says Teicher.
Corporate Development Manager, Polymateria, London
Jack Sieff
Plastic waste is a major problem for the world’s oceans, strangling marine life and jeopardising biodiversity systems. There is now an estimated 30 million tonnes of plastic waste in the world’s sea and oceans.
Founded in 2015 by Jack Sieff’s father Jonathan, Polymateria has developed biodegradable alternatives to plastic. In 2020, Polymateria reached a major milestone, achieving certified biodegradation of the most commonly littered forms of plastic packaging in real-world conditions, all without creating the harmful microplastics the world is seeking to avoid. “Since the launch of that standard, we’ve seen a domino effect,” Sieff says, as many countries are adopting similar standards.
Polymateria’s biodegradable materials are now utilised in items such as masks and wipes, along with other uses. The company raised £15 million in its Series-A funding before the pandemic hit,and is about to close out a Series-B round, bringing in a further £20 million.
Founder, DRIFT Energy, London
Ben Medland
Engineer Ben Medland didn’t know how to answer when his eight-year-old son asked him, “Daddy, why is the climate broken? And how can we fix it?” Medland’s son had been reading about a recent COP conference, and had noticed that the nearby wind farm just wasn’t moving. What could be done?
Medland vowed to try to change things by turning the 70 per cent of the planet that traditional renewables don’t reach – the world’s oceans – into an energy source. He admits that it is a “crazy” idea, but it is one that works.
DRIFT, founded in 2021, creates sailboats, augmented with turbines, which will go through the water, guided by AI to inform them of the most beneficial route to pick up power. The tides themselves generate energy into the turbine, which is stored onboard as green hydrogen using a process called electrolysis.
Better yet, that onboard green energy can then be used wherever the sailboats end up docking – bringing green energy to the parts of the world that need it the most.
