RETHINKING THE WAY WE STORE ENERGY
The global energy production is at a turning point, from carbon-based fuels and nuclear power to renewables like wind or solar. This transition can only then be successful if large amounts of highly fluctuating renewable energy can be stored. Today, electric supply must instantaneously match power consumption and new solutions for energy storage are in demand.
Efficient energy storage allows to shift energy peak production from times of large production to times of big demand. Unsteady renewable energies therewith become base-load compatible and reduce the need for conventional base-load plants running on fossile fuels.
Grid-scale Energy Storage
Today, grid-connected energy storage is almost nonexistent. Pumped-storage hydroelectricity represents the largest total capacity of stored energy worldwide. Compressed air storage, batteries and flywheels take only a minor share.
Hydrogen is a gas with extremely low density and high storage densities are difficult to achieve. At ambient conditions it takes 11 cubic meter to store 1 kilogram of hydrogen. Conventional hydrogen storage only works under very high pressures (compressed hydrogen: 200+ bars) or very low temperatures (liquefied hydrogen: – 253 °C). This generates additional risks and requires energy intensive compression and liquefaction procedures.
Hydrogenious Technologies developed the breakthrough in hydrogen storage. The safe and efficient storage of hydrogen in Liquid Organic Hydrogen Carriers (LOHC). LOHC can be stored and transported under ambient conditions in the existing fuel infrastrucutre without the need for high pressures or low temperatures. One cubic meter of LOHC can store more than 600 cubic meters of hydrogen gas and therefore about 2 MWh of energy.
Stabilization and balancing of supply and demand peaks. Maximizing usable energy output of wind and PV parks by energy production buffering. Transforming highly fluctuating renewables into a reliable energy source.
Maximizing the level of energy self-supply of apartment and office buildings up to complete autarky. Decoupling of electricity production and consumption time, from day/night up to seasonal electricity storage. Optimization of electricity and heat management.
