Is chemical storage a promising option for long term storage of energy?

With respect to these observations, the chemical storage is one of the promising options for long term storage of energy. From all these previous studies, this paper presents a complete evaluation of the energy (section 2) and economic (section 3) costs for the four selected fuels: H 2, NH 3, CH 4, and CH 3 OH.

Which energy storage technologies are included in the 2020 cost and performance assessment?

The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.

How much does CH4 cost?

The storage and the transport of CH 4 are not problematic, with a reduced cost. The global cost of CH 4 is estimated at 262 €/MWh CH4, with a transport by pipeline. The CH 4 production can be directly connected to the already well-established natural gas network. The entire industrial combustion processes are also suitable for this fuel.

How much does it cost to transport hydrogen?

Hydrogen in gas phase transported by pipeline is evaluated at 492 €/MWh H2, and 239 €/MWh H2 in liquid phase (in a truck). Storage of hydrogen in gas phase is the most expensive part of the process. This cost is due to the huge volume of storage required for 1 kg of hydrogen gas. The total cost of ammonia is moderate at 261 €/MWh NH3, by pipeline.

How much does hydrogen cost?

Global costs (production, storage, and transportation) for each fuel in €/MWh fuel, with 30 €/tonCO 2. Hydrogen in gas phase, transported in a truck is the most expensive (513 €/MWh H2). Hydrogen in gas phase transported by pipeline is evaluated at 492 €/MWh H2, and 239 €/MWh H2 in liquid phase (in a truck).
