Interest in hydrogen has ballooned as the world looks for ways to solve the growing climate crisis and cut carbon emissions. However, successful investing in this rapidly emerging sector requires a lot of deep industry analysis and the opportunities, while there, can be difficult to spot. 

That the sector has strong growth potential is not in dispute. The COP26 meeting in Glasgow last year saw countries across the globe commit to net zero emissions by 2050, set stronger targets for emissions cuts by 2030 and pledge to reduce the use of fossil fuels. 

High-profile ASX-Listed companies like Fortescue Metals Group (ASX: FMG), have outlined plans to produce large quantities of so-called “green hydrogen” produced using renewable energy. 

[Editor’s Note: Green hydrogen is hydrogen powered by renewable energy or low-carbon power. It has lower carbon emissions than other forms of hydrogen. Uses of green hydrogen include manufacturing of fertilisers and producing petroleum products].

Globally, industries such as shipping, steel making and chemical production see green hydrogen as a long-term alternative to their dependence on fossil fuels. However, demand for it as an energy carrier is still small, with niche applications like fuel cell vehicles yet to take off. 

Under production 

Hydrogen is in fact already a significant industry with worldwide production today of about 70 million tonnes per year, according to the International Energy Agency . A further 48 million tonnes is produced mixed with other gases as a by-product of industrial processes.  

The majority of hydrogen produced today is generated from natural gas through a process called steam reforming and is known as “grey” hydrogen.

“Black” or “brown” hydrogen, produced by gasification of black or brown coal, accounts for most of the rest. Hydrogen production accounts for around 2% of global carbon emissions . Currently “green” hydrogen produced using renewable accounts for less than 0.3% of hydrogen output. 

Challenges remain 

However, even green hydrogen might not be the universal energy solution that a lot of people think it is. It still faces several significant challenges, the first of which is cost: It won’t be economic (to produce) for some time yet. 

Green hydrogen is currently substantially more expensive than hydrogen produced from natural gas and coal. Costs are coming down but it's likely to take another decade or more before they get to levels competitive with fossil fuel based hydrogen, and longer again before they might reach a level to rival natural gas as an energy source. 

Nanuk Asset Management believes early applications of green hydrogen will likely focus on large projects to replace existing usage of the grey hydrogen currently being produced. 

Hydrogen’s lower energy density and very low boiling point also mean that hydrogen faces significantly higher transport and storage costs compared to natural gas. 

On top of the significant efficiency losses in converting electricity to hydrogen, pressurising and liquifying it, and converting it back into electricity further reduce its economic viability. Finally, there’s the issue of the infrastructure that is needed for a hydrogen-led economy which has largely yet to be built. 

On top of these challenges is the significant capital investment needed. Producing green hydrogen will require massive investment in new renewable energy generation that is in addition to that required to decarbonise electricity supply. 

However, in the absence of cheap and scalable carbon capture and storage, there is no viable alternative to decarbonising many parts of the economy. In short, hydrogen is likely to be a solution. Governments have recognised this and are making significant commitments to help the industry to overcome the economic challenges. 

Investment research key 

The industry is set to grow quickly with tens of billions of dollars of government funding committed over the next decade and from an investment perspective there are many areas to look at. These include suppliers of equipment and transport to the contractors involved in building hydrogen projects, gas suppliers who will own and operate the projects and utilities and power producers wanting to move into the industry. 

Nanuk is most cautious on the investment case for the electrolyser suppliers. These are the firms providing the equipment and systems that use electricity to break water into hydrogen and oxygen. The industry today has similarities to that of renewable energy equipment manufacturers producing solar panels and wind turbines a decade ago, in that it is highly fragmented with low barriers to entry and low capital costs, which will lead to significant overcapacity. 

In the short term, companies are participating in large hydrogen projects located near end-user demand and near a renewable supply. Most of these projects are likely to be heavily subsidised and selected by national funding programs that aren’t yet promoting significant price competition. In the next few years, this may favour some of the existing western equipment producers, but as the industry matures the excess value created by the subsidies will probably accrue to project owners and developers and not so much to the equipment suppliers. 

In conclusion, Nanuk Asset Management believes abundant clean hydrogen will present the opportunity to decarbonise sectors currently dependent on coal, gas and liquid fossil fuels, to revitalise old industries and start new ones.
