One of the biggest challenges that society faces today is to decarbonise our energy system and consequently move away from the reliance on fossil fuels. It is envisioned that our electricity needs are increasingly going to be covered by wind and solar as primary energy sources. These renewable sources have the disadvantage of not being constantly available. The integration of these intermittent sources into the current energy system requires a new way of storing, distributing and utilizing energy.
Decentralized and distributed electricity production provides a more economic and sustainable way to harvest renewable energy. Temporarily storing this energy however proves to be troublesome. Although battery technology is already a mature technology, it has several disadvantages for storing intermittent energy production.
By converting electricity to hydrogen gas (H2) by means of water electrolysis, a clean and multi versatile energy carrier/fuel is produced. H2 can be stored easily at a high pressure over a prolonged period of time without any loss of energy. With the aid of fuel cells H2 can be converted back to electricity featuring high efficiencies (and zero carbon emission).
Alternatively H2 can be converted into synthetic methane (SNG) by catalytic combination with captured carbon dioxide (CO2) in a process called methanation. The synthetic ‘natural gas’ can be effectively injected into existing gas infrastructures. In this way a ‘closed’ carbon loop can be realised.
Hydron Energy develops and implements renewable energy systems based on hydrogen technology. The company envisions a future where renewable energy technology has become an integrated part of day to day life. The on-site production and conversion of hydrogen is identified as one of the key enabling technologies in the future energy system.
