Harnessing nature to restore the oceans and fix the climate crisis


For All of Us

Seafields will develop proprietary underwater pipes to upwell nutrients that will feed the Sargassum we’ll grow in the mid-Atlantic.

Sargassum influx: nature’s gift to restoring the oceans and helping fix the climate emergency

Carbon sequestration needs more attention.

Stopping ongoing carbon emissions isn’t enough.

We need to scrub existing pre-industrial CO2 as well, and quickly, to avoid us reaching key climate tipping points.

Current efforts are focussed on cutting the 50 gigatons of CO2 we emit each year (GtCO2), but little thought is being put into sequestering the ~1830 GtCO2 post-industrialisation emissions that remain.

It’s difficult to visualise the scale of the problem.

One gigaton = a billion metric tons. That is the equivalent to the CO2 emissions of Germany in 1990. The 276 million cars in the US release about 1.27 gigatons of CO2 per year. The entire mass of humanity = 287 million metric tons. Sequestering more than 50 GtCO2 a year would need collaboration at a scale humanity has never seen before.

Is terrestrial carbon sequestering really nature’s best solution?

We need to plant 1.2 trillion trees to solve the problem terrestrially. The geopolitical challenge of this makes it practically unachievable, plus trees take time to grow.

Harnessing nature to restore the oceans and fix the climate crisis, SeaFields will harvest the power of the floating seaweed Sargassum to capture and store carbon at scale. Seafields is developing off-shore sustainable aqua-farms, irrigated through pipes that bring nutrient-rich waters to the surface controlling Sargassums growth, producing high value and fossil-fuel replacing products and baling and sinking the remaining carbon-rich biomass to the bottom of the ocean to lock away the carbon.

By growing, harvesting, processing, baling and sinking Sargassum in the Atlantic subtropical gyres we will be able to sequester gigatons of carbon. Alongside this, we will wholesale raw Sargassum to industry partners who provide alternatives to fossil fuel products, helping the global effort to rapidly lower CO2 emissions. The end goal is a world with very low carbon emissions, where our sequestered carbon is even scrubbing the historical CO2 emissions.#Climate #COP26 #sargassum ... See MoreSee Less

Sargassum is a seaweed, or brown algae, that can double its weight in 2 weeks, sequestering about 50 units of carbon per nutrient provided and as soon as its bladders burst it will sink fast to the deep sea, storing that carbon. Sargassum is our best chance to help fix the climate crisis and restore the oceans.#worldalgeaday #algea ... See MoreSee Less

Reducing ongoing carbon emissions fast is critical, but it isn't enough. We also need to offset those emissions that we cannot avoid and scrub our historical CO2 emissions to achieve pre-industrial safe and life sustaining conditions. Seafields aims to provide a nature-based solution to remove significant amounts of CO2 from the atmosphere and store it safely in the ocean.Learn more about the project. seafields.eco/#Climate #COP26 ...
