Biomass gasification combined heat and power (CHP) systems convert organic waste into synthesis gas for electricity generation while capturing waste heat for industrial processes, achieving 80-90% overall efficiency. These systems can process 10-100 tons of biomass daily producing 1-10 MW of electricity plus thermal energy. Companies like Nexterra and Ankur Scientific deploy systems with costs of $3,000-6,000 per kW and feedstock costs of $30-80 per ton.
Flywheel energy storage systems store kinetic energy in rotating masses spinning at 20,000-50,000 RPM, providing millisecond response times for grid frequency regulation with 85-95% round-trip efficiency. These systems deliver high power output for 15-60 minutes with 20+ year operational lifespans and minimal maintenance requirements. Companies like Beacon Power and Vycon deploy flywheel systems costing $1,000-4,000 per kW for power quality and backup applications.
Gravity energy storage systems store energy by lifting heavy masses during excess electricity periods and releasing them to generate power when needed, achieving 80-90% round-trip efficiency with 4-8 hour duration storage. These systems use abandoned mine shafts, purpose-built towers, or underground caverns with 35-year operational lifespans. Companies like Energy Vault and Gravitricity are deploying commercial systems with costs targeting $150-300 per MWh.
Liquid Air Energy Storage (LAES) systems store energy by liquefying air at -196°C during off-peak periods, then releasing and expanding the liquid air to drive turbines when power is needed. LAES achieves 50-70% round-trip efficiency with 4-8 hour duration storage and virtually unlimited capacity scaling. Highview Power has deployed commercial systems including a 50 MWh facility in the UK, with costs targeting $140-200 per MWh.
Revolutionary battery technologies including lithium-air batteries achieving 1000+ Wh/kg theoretical energy density and all-solid-state batteries demonstrating 500+ Wh/kg with enhanced safety.
Sodium-ion batteries use abundant sodium instead of lithium for energy storage, offering a potentially lower-cost alternative for grid storage. Commercial production began in 2023 with energy densities of 120-150 Wh/kg and costs projected to reach $40-60/kWh by 2030 .
Lithium Iron Phosphate (LFP) batteries offer a safer, longer-lasting alternative to conventional lithium-ion batteries. With lifespans exceeding 6,000 cycles, LFP batteries provide enhanced thermal stability and reduced fire risk compared to other lithium-ion chemistries. Cost /kWh with energy densities of 90-120 Wh/kg, making them ideal for electric vehicles, grid storage, and stationary applications where safety and longevity are prioritized over energy density.
Green hydrogen is produced through electrolysis using renewable electricity to split water into hydrogen and oxygen, creating a carbon-free energy carrier. Current production costs are $3 -6 per kg, with targets to reach $1-2 per kg by 2030 through improved electrolyzer efficiency and scale. Global capacity is expected to reach 25 GW by 2026, up from less than 1 GW in 2020.
