Hydrogen Fuel Cells Reshaping Energy
By Mohamed Ismaili • • Senior Technology Analyst, Smart Flow Lab • 5 min read
Innovations in hydrogen fuel cells are transforming the energy landscape
As the world grapples with the challenges of climate change, a surprising fact has emerged: hydrogen fuel cells are poised to play a significant role in reshaping the energy landscape, with estimates suggesting that the climate tech market will reach $312.74 billion by 2035, according to a report by SNS Insider. This raises an important question: can hydrogen fuel cells and next-generation battery storage technologies work together to create a more sustainable energy future? According to a recent report by Custom Market Insights, the global second-life battery market is expected to reach USD 46.9 billion by 2035, growing at a CAGR of 11.8%, which could have significant implications for the adoption of hydrogen fuel cells.
The Bigger Picture
The shift towards sustainable energy technologies is being driven by a combination of factors, including falling battery costs and increasing investment in clean energy. As reported by ABC News (AU), the CSIRO has found that batteries are now cheaper than gas for meeting peak power demand, which could have significant implications for the energy sector. Additionally, the Comprehensive Economic and Trade Agreement (CETA) between India and the UK is expected to facilitate mutually beneficial investment, innovation, and industrial collaboration, as noted by Ficci president in an article published in Livemint.
Data In Focus
The data suggests that the energy sector is undergoing a significant transformation, with hydrogen fuel cells and next-generation battery storage technologies playing a key role. According to a report by GlobeNewswire, the global second-life battery market is expected to reach USD 46.9 billion by 2035, growing at a CAGR of 11.8%. Furthermore, the climate tech market is projected to hit $312.74 billion by 2035, driven by clean energy investments and carbon removal technologies, as reported by GlobeNewswire. This growth is also reflected in the performance of ASX ETFs, with some returning better than 80% over the past year, as noted by Motley Fool Australia.
Winners And Losers
The shift towards sustainable energy technologies is likely to create both winners and losers in the energy sector. Some of the key winners are likely to include:
- Companies that invest heavily in hydrogen fuel cells and next-generation battery storage technologies
- Countries that prioritize clean energy investments and carbon removal technologies
- Investors who put their money into ASX ETFs that focus on emerging sectors such as climate tech

My Take: Hydrogen Fuel Cells and the Future of Sustainable Energy
In my view, the recent surge in investments in hydrogen fuel cells and next-generation battery storage is a clear indication that the energy landscape is undergoing a significant transformation. With the global second-life battery market expected to reach USD 46.9 billion by 2035, growing at a CAGR of 11.8%, it's evident that the industry is shifting towards more sustainable and efficient energy solutions. However, I challenge the mainstream assumption that gas will remain a dominant player in meeting peak power demand - as reported by CSIRO, falling battery costs and the increasing demand from data centers have made batteries a more cost-effective option. Furthermore, the climate tech market is projected to reach $312.74 billion by 2035, driven by clean energy investments and carbon removal technologies, which will likely have a profound impact on the adoption of hydrogen fuel cells. As I see it, the next 6-12 months will be crucial in determining the trajectory of this market, and I will be closely watching the developments in the India-UK trade agreement, particularly the Comprehensive Economic and Trade Agreement (CETA), which is expected to facilitate mutually beneficial investment and innovation in the clean energy sector.
Bottom Line
In conclusion, the energy sector is undergoing a significant transformation, driven by the adoption of hydrogen fuel cells and next-generation battery storage technologies. As the climate tech market continues to grow, it is likely that we will see significant investment in clean energy and carbon removal technologies. Companies that prioritize sustainability and invest in emerging sectors such as climate tech are likely to be the winners in this new energy landscape. As noted by analysts, the shift towards sustainable energy technologies is a trend that is here to stay, and companies that fail to adapt risk being left behind.
