summary draft 2 and thesis
Michigan Tech's article "An Energy Breakthrough: Tech
Researchers Create New Type of Fuel Cell"(2023) states that hydrogen fuel
cells are making advancements and have a role in making clean energy for the
world. Fuel cells emit zero emissions, and it is highly efficient as it
requires less energy to convert to electrical energy. The efficiency rate for
fuel cells is 60% whereas for normal fuel engines is at 30 to 35%.
There are various types of hydrogen fuel cells being
utilised in the market. One of the examples will be the Proton Exchange
Membrane (PEM) cells. PEM cells generate electricity by using hydrogen and
oxygen. Hydrogen reacts with oxygen to produce electricity; it powers electric motors and emits only water vapour. PEM cells are currently being used in the Hyundai Nexo 2019 model.
PEM cells have demonstrated a quick start and effective energy generation. It can
operate at low temperatures, which is great for automation and portable uses
while having high power density. However, pure hydrogen is required for PEM
cells and is vulnerable to fuel impurities like carbon monoxide.
Despite their advantages, fuel cell plants face challenges like production costs and transportation issues. Hyundai Motor Company (2013) stated that it costs 1.1 billion dollars to upgrade two fuel cell plants due to the need for expensive materials like platinum. Hydrogen is a flammable liquid and requires high-pressure tanks and cryogenic tanks, which are costly.
Moreover, despite their interest in the technology, Southeast Asian countries like Singapore lack specialised refuelling infrastructure. Producing hydrogen requires significant energy, relying on non-renewable sources, which undermines the purpose of environmental benefits.
In conclusion, hydrogen fuel cells are a promising choice for traditional sources like fuel. However, technical and economic challenges are problems we face. As more nations become interested in this innovative technology, there might be more potential to transition to cleaner and more sustainable energy sources.
Thesis statement: Hydrogen fuel cells could help revolutionise clean energy, but without significant technological advancements in infrastructure and cost, their potential will remain unrealised.
