Green hydrogen - Powering the transition to net zero

The energy landscape is going through its biggest transition in a generation. Consumers are pushing for sustainable energy, and governments are making ambitious commitments to tackle climate change and reach ‘net zero’ emissions.

Green hydrogen is a truly carbon neutral solution that can play a significant role in enabling the transition to net zero. It relies on new sources of renewable energy, such as wind or solar power, to split water into oxygen and hydrogen using electrolysis. Scale up of green hydrogen production will increase the role of electricity in hard to decarbonise areas, including transport, heating, and chemical industries, where it plays a small role today.

Although green hydrogen is more expensive to produce than grey or blue hydrogen today, it is the only zero carbon option and the key input - renewable energy - is both increasing in capacity and reducing in cost. The challenge for industry is to be ready to provide affordable, reliable green hydrogen into the supply chain when renewable energy sources are in place to meet demand.

What is beyond doubt is that green hydrogen will play an increasing role in the transition to net zero as the cost of renewable electricity continues to fall and the cost of electrolysers reduces due to technical developments, mass manufacture, and development of supply chains.

We are focused on development and large scale manufacture of the catalyst coated membranes (CCMs) which sit at the heart of proton exchange membrane (PEM) and anion exchange membrane (AEM) electrolysers. Building on Johnson Matthey’s expertise in catalysis, decades of experience in fuel cells, and centuries developing pgm products in high performance applications, we can be the world’s leading supplier of electrolysis CCMs, driving down costs and enabling a circular supply chain at the heart of electrolyser systems.
