An Emerging Alternative



Everyone knows that within the next 10 years, all the conventional tools and methods of

conventional engineering branches will change or you can say it has started and its

foundation already laid down 2-3 years back. So in the long run, we need to start thinking

about Alternative energy. Green hydrogen is frequently seen as a miracle innovation. It

changes water into a gas that can be put away, shipped, and utilized as a feedstock in

industry, as a transportation fuel, as a warming fuel, or to produce power in different

applications. The creation of green hydrogen just delivers oxygen as a by-product, and its

utilization just creates water. Its allies see green hydrogen assuming a solid part later in the

energy sector, with up to 20% of complete energy being provided by 2050. Other analysts

see a much more modest role, likely limited to the replacement of current grey hydrogen as

an industry feedstock, plus usage in some other hard to abate sectors like the steel industry,

where hydrogen can be used for direct iron ore reduction. The innovation to create green

hydrogen has been accessible for two centuries - in the lab and as pilots and limited scope

units. Just one huge scope plant, in Norway, has been running for a lot of time (indeed over

60 years).

How soon it will change Gas sector depends on these factors –

Price decrease of renewable electricity - Even with low-cost renewables and

high-efficiency hydrogen generation, the cost of green hydrogen is likely

to be $1.5 – $2/kg which is about $12 – $15/MMBtu by 2030. For half the world, this is a

good price; for the other half, this is too high a cost. The relevance of green hydrogen may

depend on local regulations such as carbon taxes. One also needs to integrate the

intermittency of renewable electricity. It might not be massively available permanently,

meaning the green hydrogen production plant may not be running 24/7/365, which

increases the average production cost from slower capex amortization, especially as

intermittent operations would lead to the choice of PEM electrolyzers, which require higher

capex.

Cost abatement of electrolyzers - Electrolyser costs are today around $850/kW, yet the

providers are headed to accomplish economy of scale and expectation to learn and adapt

impacts. Electrolyzer expenses of $300/kW are as of now accessible in China, and sensible

assessments recommend that electrolyzers could be broadly accessible for $200/kW by

2030 and $100/kW by 2050. Cost decrease of green hydrogen Balance of Plant, securing

yield & uptime, connection with grids, financing of renewable electricity supply.

Availability and perennity of government subsidies - Several governments have today

committed to funding green hydrogen projects, but public financing may switch to more

short-term Covid-impact mitigation subsidies and funding. Would-be green hydrogen

project operators may need to turn to public-private partnerships between government

entities and private capital.

The nitrogen oxides (NO x ) discharges - In different hydrogen ignition measures (gas

turbines, internal burning motors, boilers, and so forth) the higher fire speed of hydrogen


burning builds the fire temperature locally, which can produce significant degrees of NO x .

NO x outflows make corrosive downpours, deforestation, and breathing sicknesses. It took

the US 15 years to improve the outflow guidelines for NO x and an additional 15 years for the

energy business to decrease NO x by 84%.
