The future of natural gas

Renewable Gas

Renewable natural gas (RNG) emerges as a potential alternative to traditional natural gas, with its production rooted in biological pathways. Andy Lubershane explains that RNG is primarily sourced from methane emissions from landfills and livestock, making it a niche yet net-zero carbon fuel. However, its scalability is limited, necessitating more complex technological pathways like gasifying cellulosic biomass to expand its supply 1.

Renewable natural gas is methane, just like normal natural gas, but it's produced from various biological pathways.

Despite its potential, RNG remains significantly more expensive than conventional natural gas, posing challenges for widespread adoption 1.

   

Hydrogen

Hydrogen presents a promising yet challenging alternative to natural gas, particularly in existing energy systems. Andy Lubershane highlights the difficulties of integrating hydrogen into current pipelines, noting that most can only handle up to 20% hydrogen by volume without significant retrofits 2. The transition to hydrogen requires substantial infrastructure changes, especially for older metal pipes, to prevent leakage and corrosion.

The challenge for replacing natural gas with hydrogen in existing pipelines, I guess there's multiple layers of challenge.

Building new hydrogen-specific pipelines or repurposing existing ones could offer a more feasible solution, particularly for transporting green hydrogen produced from renewable sources 3.
