Energy storage

what forms of energy are there

potential energy, kinetic energy, chemical, mechanical, nuclear, gravitational, movement, electricity, heat, sound, light

how is energy stored

Mechanical- compression, tension, motion Chemical- batteries, gases, solid fuel, food

what are Pneumatics

compressed air or gas used to create movement

what are Hydraulics

pumped and compressed liquid used instead of air which creates more powerful system

what is wrong with batteries

contain toxic chemicals and metals which can leak into soil and water, harm wildlife, need recycling specialist

what are some new emerging batteries

Flow batteries- large units used to smooth demand on national grid, Sodium/ glass batteries- super fast charging with high capacity

where is the demand for rechargeable tech

portable domestic appliances, disability transport, hybrid and electric vehicles, mobile devices

benefits to portable energy storage

no need to plug in to main supply, not restricted by cable length, can be moved, smaller product size

Alkaline Batteries

more efficient, higher capacity, more charge can be stored in same size, hold charge well

what does chemical energy storage include

batteries, canisters, flammable gels and liquids(petrol), hydrogen fuel cells

why are kinetic Energy Recovery Systems used

to save energy on vehicles
