The chemical energy of a fuel is converted to electrical energy using an electrochemical mechanism in fuel cells. Fuel cells are used for distributed generation (electricity only) and are also set up for combined heat and power (CHP) for stationary power.
When implemented in new low-energy buildings, the most highly efficient fuel cell micro-CHP technologies can be run in accordance with electricity demand; nevertheless, they are also acceptable for existing structures.
The Fuel Cell micro-Cogeneration is well suited to the evolving trend in buildings towards higher electricity use and low space heating demand because it has a low “heat-to-power ratio” (meaning it produces a relatively low amount of heat and a relatively high amount of electricity compared to other micro-Cogeneration technologies).
Since these micro-cogeneration systems can effectively generate both useable heat energy and electricity from a single fuel source, there is significant potential for their usage in the residential sector.
Global fuel cell CHP system market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A new fuel cell system (FC-5B) will be introduced to the market by Miura Co., Ltd. in October. The new fuel cell system was created in collaboration with Ceres Power in the UK and is a 4.2kW combined heat and power product (CHP) aimed for the Japanese commercial building market.
The units will run on a mains gas supply and offer commercial buildings clean energy and hot water in a highly effective and low-carbon way.
As commercial users may receive the electricity and hot water the unit produces from the existing city gas supply even during power outages, the systems will also give businesses more supply certainty, promoting business continuity.
Miura has been working on system development for solid oxide fuel cells (SOFC), which have distinct advantages over other types of fuel cell technologies because of their high electrical efficiency and durability, in order to realise the potential of distributed energy.
The first SOFC system model from Miura was the FC-5A, a new model with a number of enhancements, including a better electrical efficiency of 50% net AC (LHV)**.
The system’s overall efficiency is 90% since the exhaust heat is converted into hot water, which allows users to save energy and leave a smaller carbon impact.
