Renewable Hydrogen Sources For A Green Economy

Employing renewable source-based electricity facilitates feasible outcomes for efficient green hydrogen technology and thus burnishes the economy.

FREMONT, CA: Hydrogen technology is gaining critical importance with a surge in strategies, policies, and hydrogen projects, in addition to a relative sublime in politics and business growth. Its intervention is limitless in the mining sector, thus forming part of several miner decarbonisation pathways to feature as carbon-free fuels in heavy equipment and in generating electricity for power processing plants. Tests for these efficient alternatives have already begun, with successful outcomes to follow. However, the industry is highly influenced by emerging technology trends that could yield plausible advancements accordingly.

Hydrogen technology advancements are increasing the value of electrolysers as their measuring calibration has increased from megawatts (MW) to gigawatts (GW). Moreover, its cost-efficiency has been decreasing constantly since the past decade. However, achieving these reductions is often assisted by innovations in enhancing electrolyser performance, manufacturing capacity, and standardisation with rising scale economies. The enlisted advantages are vast as the green hydrogen’s cost is likely to be affordable at 2 USD per kilogram, boasting a breakthrough in cost competitiveness. Similarly, the cost of electrolysers has also declined by 40 per cent and is anticipated to reach 336 USD per kilowatt with the deployment of capacity by 100GW. As a result, renewable hydrogen will become the preferred choice in the future for a clean hydrogen supply in various greenfield uses.

An increased focus on the new market initiatives is burgeoning owing to their enhancements in electrolyser capacity and technology. Besides, energy leaders are coming up with effective collaborations to facilitate a sole dedication to electrolyser technology. In the due course, electrolysers’ are likely to become pivotal in shaping the application areas such as industry hydrogen production, Power-to-X strategy management, and power grid stabilisation. This renewable electricity-oriented hydrogen, stabilised with an electrolyzer, aids in the integration of large amounts of variable renewable energy, such as wind and solar photovoltaic (PV), into the energy system.

Hydrogen generally acts as the source of energy storage for renewable electricity, where electrolysers facilitate the affiliation of the energy into electric power systems. Its electricity consumption is highly modified to orient with solar PV and wind power generation. They enable flexible load and grid balancing services like ramping up and down of frequency regulation in correspondence with optimal capacity functioning to meet industrial hydrogen demands and the transportation sector for injecting a natural gas grid.

Hydrogen energy storage is likely involved in real-world projects and thus accesses power-to-gas (P2G) technology through which electrolysers powered by the on-campus solar system are set up to fill renewable hydrogen for the campus power plants. Similarly, renewable energy sources such as wind and power are emerging as building blocks of the green hydrogen economy. Hence, green hydrogen adoption’s progression is highly dependent on the economy of renewable power generation.
