Our mission is to have the world’s largest network of seaweed farms by 2030 to naturally remove CO₂ from our oceans and atmosphere

What We Do

At Carbon Kapture, we work with customers around the world to grow seaweed and absorb vast amounts of CO₂. We then dry the seaweed and trap the carbon through a process called pyrolysis. Once done, we store it in the ground by donating it to farmers who use it to improve the quality of their soil. It’s not a simple process but one with the benefit of instant impact, roughly 30x the speed of trees. Companies (and individuals) can sponsor ropes of seaweed annually – we have a range of packages available according to the level of positive impact desired. By working with us, we can grow seaweed, improve aquaculture, trap CO₂, provide nutrient-rich biochar to local farmers, create jobs, and tackle climate change in real time. Join us.

How it Works

Step 1

Sea absorbs CO₂

Step 2

Seaweed grows and absorbs the CO₂

Step 3

Jerry and crew harvest the Seaweed

Step 4

Dave and team turn the seaweed into Biochar

Step 5

Biochar is given to local farmers who use it to improve soil health and crop growth

Our Objective

By the end of 2025, we aim to have put one million metres of rope into the sea as our first step towards building the world’s largest network of seaweed farms. Our first farm is located in Mulroy Bay, along the Wild Atlantic Way in North Donegal, Ireland.

We are also in the process of discussing farm partnerships in Singapore, Newfoundland, and Seychelles. Our operations team will continue to search for and build partnerships with seaweed and shellfish farmers across the globe. 

We are keen to prirotise discussions with UK farms, if you would be interested in knowing more about our partnership model please get in touch.

Grow Seaweed

We are a blue planet. We will never be able to counterbalance the amount of fossil fuels we burn by only growing trees. Earth is approximately 70% water, with seaweeds representing some of the fastest growing organisms on the planet. While the idea of planting trillions of trees sounds nice and definitely helps to some extent, Species, such as Giant Kelp, grow up to 30cm per day in the ocean. They also offer a powerful and scalable carbon drawdown solution that can sequester more carbon per square kilometre than forest ecosystems.

Local community

We are working with communities and local governments to bring climate-positive change and create a circular economy. By growing seaweed, we remove and trap tonnes of carbon from the sea, improve marine biodiversity, and create employment opportunities. Then, by producing biochar, we are able to put this type of carbon to good use in both local agriculture and construction.


Through a process called pyrolysis, we turn our dry seaweed into biochar and give it to local farmers.

When applied to farmland, it enhances soil carbon sequestration, boosts soil’s fertility and its ability to withstand drought or flooding. It can also rid soil of heavy metals and other pollutants. And adding the right type of seaweed to cattle feed can reduce methane output by up to 95%.

Please contact us if you think our biochar can create a climate positive impact in your company or supply chain

Farm partnerships

By working with seaweed and shellfish farmers around the world, we aim to deliver stronger economies for coastal communities, whilst supporting and creating jobs through a healthier marine environment. Our seaweed also benefits and improves the local ecosystems of the farmers we work with, helping produce higher quality shellfish.

If you are interested in discussing a farm partnership, please get in touch.

Create positive social impacts

Seaweed farming can also offer job opportunities for coastal communities where unemployment rates can sometimes force people to leave a town to find work. Carbon Kapture will work alongside local government to bring employment to the areas we are investing in. It’s not just about solving the climate crisis – it’s about well-being for all. 

We are always looking for volunteers, from harvesters to academics. If you are interested please register your interest in becoming a Kelper.
