Hydrogen has long been identified as key in the transition to a decarbonized energy system, but it has traditionally been produced in ways that generate greenhouse gases. Green hydrogen—produced using renewable electricity sources—could solve that problem.

Green hydrogen is an energy source that can provide clean and efficient energy for vehicles and industrial processes. And it can accelerate decarbonization of even hard-to-green sectors, adding an emission-free alternative to the decarbonization mix, alongside fossil fuels that currently provide four-fifths of the world’s energy supply and create the majority of global greenhouse gas emissions.

So, how do we build an economy powered by green hydrogen?

The immediate challenges are capacity and cost. Green hydrogen is currently a scarce resource, and an expensive one because of factors such as production and transportation costs. Meeting increasing demand begins with energy companies investing in renewable energy sources, developing advanced electrolysis technologies, and scaling up production facilities. Increasing the production of green hydrogen will likely bring its cost down, making its use a viable commercial proposition and supporting the wider renewable energy sector, which is central in the global effort to address climate change.

For investors looking to invest in the opportunities this presents, BlackRock helps clients understand how they may be able to mitigate risk and capture opportunity associated with climate change and the transition to a low-carbon economy. Having identified this transition as a megatrend—a long-term driver of change poised to disrupt many aspects of the global economy—the firm seeks to connect investors to these opportunities.

“Climate change and resource scarcity are arguably the biggest challenges for our generation,” says Rob Powell, Head of Thematic and Sector Product Strategy at BlackRock. “We’re seeing opportunities arise for companies in many different sectors to contribute to and benefit from the transition to a low-carbon economy.”

From climate crisis to climate opportunity

While much of the discussion around climate change has centred on the challenges, deploying commercially mature renewable power technologies could address them. Today, the focus has widened to explore the opportunities that disruptive technologies present to increase climate action momentum.

The hydrogen sector and its opportunities are growing rapidly. Hydrogen projects attracted $240 billion in proposed investment as of September 2022, according to the Hydrogen Council—a figure that grew 50% since November 2021.

Green hydrogen specialist McPhy Energy is supporting this growth in Europe, and over the next few years, it aims to dramatically scale up its manufacture of equipment to produce and distribute hydrogen.

“We have a major role to play in the decarbonization value proposition,” says Jean-Baptiste Lucas, McPhy’s CEO. “We’re aware of the drastic need to cut CO2 emissions, and hydrogen technology brings concrete solutions that could be implemented to substitute for CO2-emitting technologies. One of the main challenges is to scale up production and move from proof of concept to full-size industrial equipment. We need larger manufacturing sites and factories.”

McPhy believes that hydrogen has the potential to reduce reliance on carbon-intensive fossil fuels. Hydrogen production is a zero-carbon process when renewable electricity is used to electrolyze water, producing green hydrogen, which is a far more carbon-efficient fuel than diesel or natural gas.

The French government agrees, and has provided funding to McPhy toward the construction of a new “gigafactory” in Belfort, in northeastern France, that is expected to add up to a gigawatt of annual hydrogen production capacity.
