Natural gas V Bioelectricity with biochar

Here's an interesting thread I started on perplexity.ai with the following prompts for research trawling the web:

• is natural gas or bioelectricity more complementary to big batteries

• biomass waste pellets to Biochar and bioelectricity and their complementary role to big batteries for renewable energy storage and despatch

• do carbon removal credits for biochar make Bioelectricity cheaper than natural gas as a complement to big batteries

My interpretation of these results suggest that bioelectricity with biochar production (via pyrolysis and 'Carbon negative') stacks up both economically and technically compared to natural gas as a complementary technology to big batteries used to store and despatch renewable energy.

But - as per usual I would suggest the search results and references are starting points/keywords for deeper academic research. Maybe there are already academic reports on this topic available for the Australian context? However, I wouldn't limit this idea to any specific Country since both biomass waste and other renewables eg. solar, wind etc. are probably available in most populated places on Earth.

What do you think?
