In Episode 95 of Green Giants: Titans of Renewable Energy, Wes Ashworth sits down with Salim Rahemtulla, President and CEO of PowerTap Hydrogen Fueling Corp., for a grounded, real-world conversation on hydrogen, infrastructure, and what it actually takes to build in a volatile market.
With a background as a U.S. Naval Officer and over $1 billion in infrastructure projects delivered, Salim brings operational discipline and strategic clarity to one of the most misunderstood sectors in energy.
This episode moves beyond the hype cycle and into execution.
In this episode, we cover:
- How Salim’s military background shaped his approach to risk, systems thinking, and decision-making in hydrogen
- Why infrastructure success depends on stakeholder alignment, permitting strategy, and long-term operational planning
- What most cleantech founders underestimate when navigating bureaucracy and building physical assets
- The reality of raising capital during market downturns and how to maintain conviction through uncertainty
- Lessons from navigating failed partnerships, shifting investor sentiment, and multi-year capital challenges
- Why resilience and team alignment are critical when building in emerging energy markets
- The strategic pivot into data center backup power and why it unlocked new investor interest
- The difference between hydrogen hype and real market demand across heavy industry and energy systems
- Common misconceptions around hydrogen safety, cost, and scalability
- Why on-site hydrogen production can eliminate logistics costs and improve economic viability
- The role hydrogen already plays in industries like ammonia, refining, aerospace, and chemicals
- Where hydrogen has the greatest decarbonization potential, including steel, cement, and maritime
- Why hydrogen is not just a bridge technology but a long-term pillar of the energy system
- The importance of narrative, communication, and education in scaling clean energy solutions
This episode is ultimately about resilience, discipline, and clarity of mission. It is a candid look at what survives when markets shift, capital tightens, and only the most grounded operators continue building.
If you are working in clean energy, infrastructure, or climate tech, this conversation offers practical insight into how real progress gets made, especially when the path forward is not obvious.
