Hydrogen’s Prospective Relevance
Sponsored Post:
Thirty years ago, hydrogen was identified as a critical and indispensable element of a decarbonized, sustainable energy system” to provide secure, cost-effective, and non-polluting energy. Today, energy leaders see hydrogen as the lowest impact and least certain issue facing the global energy system. Hydrogen, as a viable alternative fuel, continues to promise much and deliver precious little. Yet hydrogen could play a significant role in the low-carbon future: counterbalancing electricity as a zero-carbon energy carrier that could be easily stored and transported; enabling a more secure energy system with reduced fossil fuel dependence; with the versatility to operate across the transport, heat, industry and electricity sectors. Together, these account for two-thirds of global CO2 emissions.
Whilst electricity is proving comparatively easy to decarbonize thanks to the dramatic cost reductions and uptake of renewables, these other sectors must not be forgotten. In the UK for example, heat and transport are anticipated to decarbonize at just one-third the rate of electricity production, with emissions crumbling around 24% compared to about 68% over the coming 15 years. Solutions are desperately needed to make transport and buildings sustainable that are cost-effective and appealing to consumers. Hydrogen and fuel cell technologies offer greater personal choice in the transition to a low-carbon economy, given their similar performance, operation, and consumer experience to fossil-fueled technologies. They also provide valuable insurance against the possibility of other vaunted technologies failing to deliver, such as carbon capture and storage, bioenergy, and hybrid heat pumps.

Hydrogen has very special properties as a transportation fuel, including a rapid burning speed, a high effective octane number, and no toxicity or ozone-forming potential. It has much wider limits of flammability in the air than methane and gasoline. Hydrogen has become the dominant transport fuel and is produced centrally from a mixture of clean coal and fossil fuels (with C-sequestration), nuclear power, and large-scale renewables. Large-scale hydrogen production is probable on a longer time scale. In the current and medium-term, the production options for hydrogen are first based on distributed hydrogen production from the electrolysis of water and reforming of natural gas and coal. Each of the centralized hydrogen production methods scenarios could produce 40 million tons per year of hydrogen.

Hydrogen production using steam reforming of methane is the major economical method among the current commercial processes. In this method, natural gas feedstock costs generally contribute approximately 52–68% to the final hydrogen rate for larger plants, and about 40% for smaller plants, with remaining expenses composed of capital charges.
