Decarbonisation

2H helps clients accelerate their path to net zero energy creation by applying proven system design and combining it with new technology to reduce, prevent and remove carbon emissions.

Net zero and the reduction of carbon is one of the greatest challenges that the world faces today. While the energy industry is moving fast from fossil fuel towards renewable sources and carbon-free production, making a significant impact on reducing emissions requires a multi-faceted approach and a combination of creative system design and innovative technologies.

As a leader in advanced systems engineering for the marine energy sector, 2H is playing its part to help clients on their journey to net zero. We are driving three main approaches:

1. Reducing carbon emissions by improving the efficiency of existing conventional energy production & operations.

2. Preventing future carbon emissions by enabling and optimising clean sources of energy.

3. Removing carbon emissions by creating innovative solutions for capture and storage.

Leveraging our unrivalled knowledge of marine engineering and riser, conductor and platform systems, our goal is to unlock technologies to help accelerate marine energy decarbonisation.

Our independent, holistic approach means we can identify the challenges and assess a wide range of technology that can deliver the maximum CO2 benefit, whilst being economically feasible.

Applying our domain knowledge and advanced systems engineering expertise, we help find solutions that are both efficient and effective, using greener designs and more sustainable methodologies & materials.

Our capabilities apply to all project phases from site potential and permitting, surveys, concept feasibility, FEED and detailed system design, to procurement, installation, and operations monitoring and integrity.

Our global team of engineers offers expertise in a range of disciplines:
