Algae-based energy storage sidesteps lithium's supply chain vulnerabilities and environmental extraction costs, but faces the harder problem of scaling manufacturing from lab prototypes to billions of consumer devices. The real test is whether companies can make it cheaper and more reliable than incremental lithium improvements, which continue to advance. This matters less as a lithium killer and more as a hedge against supply shocks, particularly for non-critical low-power applications where traditional batteries currently dominate by inertia rather than performance.
