6 GreenTech startups based in Ireland are revolutionizing climate impact

Ireland happens to be the country that prototyped its first wooden computer. This ingenious development is enough to instill confidence in Ireland’s mission to revolutionize climate impact. But is MicroPro the only company? Definitely not, and here we have 6 Ireland-based GreenTech startups that are garnering global attention to cement hope for a greener, more sustainable future.

At sea

Based in Dublin, Ireland, Seabased is a wave energy company that provides large-scale power farms that use ocean waves as fuel and operate independently or with offshore wind. Seabased’s ambition is to become the first Blue Energy Company to build, own and operate Wave Power Parks worldwide. Seabased was founded in 2019 by Hans Bernhoff and Mats Leijon with the ambition to become the first Blue Energy Company to build, own and operate Wave Power Parks around the world. Seabased strives to produce renewable, CO2-free energy while respecting the environment. Its wave parks are practically invisible and require little maintenance. The materials used and the mechanics of the parks are chosen to protect the water and the creatures that live there.


Among 6 Ireland-based GreenTech startups, Dublin-based Wattics is a web-based energy management software that connects to smart meters, sensors and business data to provide the analytics needed to keep your business thrifty in energy. Wattics was founded in 2011 with a global mission to fight climate change with powerful and innovative software as an energy analytics service. Wattics offers a unique cloud-based data analytics and BI platform for teams of energy consultants, energy analysts and energy managers that is transforming the global energy management market. energy, enabling better cost control and asset management, from long and static Excel spreadsheets to enabling new energy services that energy professionals deliver to their customers at scale. On October 1, 2013, the company raised €650,000 in seed funding from Enterprise Ireland and Irrus Investments.

BNRG Renewables

Based in Dublin, Ireland, BNRG Renewables is an international renewable energy development company. BNRG’s work covers all aspects of development, including site assessment, securing planning and grid connection rights, construction management and long-term asset management. According to the BNRG, solar energy is not only the best option to combat climate change, but can also be provided at a lower cost than traditional fossil fuel generation. The BNRG installed 148 MW, powered around 23,690 homes and saved 154,000 tonnes of CO2. On May 29, 2022, the company raised approximately $115 million in a debt financing round from Societe Generale.

Dare Tech

DARE Technology, based in Cork, Ireland, is an Irish engineering company established to develop and commercialize patented clean energy technology. DareTech designs and manufactures products that are robust and suitable for the environment in which they operate. DareTech uses the best renewable resources available at the project site. DARE Technology’s first product is a unique crane-mounted wind turbine for ships that aims to replace the use of diesel generators during ship downtime. Using the existing crane allows much larger turbines to be deployed, making it a viable alternative for powering the vessel during downtime and greater fuel savings and emissions reductions. On May 31, 2017, the company won a €50,000 grant from EASME – EU Executive Agency for SMEs.


And here is Ecocem, one of the 6 GreenTech startups based in Ireland, a cement manufacturing company.

The cement used in the construction industry has a massive carbon footprint. This is why Ecocem is focused on manufacturing a low carbon alternative. Ecocem manufactures granulated ground blast furnace slag (GGBS), which it claims produces 32 kg of CO2 emissions per tonne, compared to more than 800 kg for ordinary cement. According to Ecocem, the race for technological advances that will help us reach net zero carbon emissions by 2050 is on.

Fusion Fuel

One of the 6 GreenTech startups based in Ireland is Fusion Fuel (NASDAQ: HTOO). Fusion Fuel is in the production of green hydrogen. Fusion Fuel was founded in 2017 with a mission to provide the world with innovative green hydrogen solutions that accelerate the transformation of the global energy sector and enable the sustainable reduction of carbon emissions. Fusion Fuel has developed a revolutionary new electrolyzer design – the HEVO – which will allow it to produce hydrogen from renewable energy at very competitive costs without any associated carbon emissions. Fusion Fuel claims to avoid 25,000 tons of CO2 emissions and produce more than 25,000 tons of green hydrogen per year by 2025.
