Single Cylinder Internal Combustion Engine Fuelled with H2NG Operating as Micro-CHP for Residential Use: Preliminary Experimental Analysis on Energy Performances and Numerical Simulations for LCOE Assessment

Abstract

The paper presents data resulting by the preliminary experimental campaign performed on a micro CHP (combined heat and power) pre-commercial version (5 kWel) designed for dwellings. The engine employs the lubricant oil as the jacket coolant to simplify the heat recovery architecture and it was equipped by a condensing heat exchanger as well. The tests have been carried out at rated and partial load up to 2.9 kWel (59% of rated load) in condensing mode, fuelling the NG engine with hydrogen percentages equal to 0% vol. and 15% vol. In order to evaluate the CHP energy performance, the analysis was conducted for 160 h, using an alkaline electrolyser for hydrogen production, a static heat meter and two mass flow meters for both hydrogen and NG. The aim of this paper is to illustrate how the use of the hydrogen enrichment in a micro CHP plant, based on ICE technology, represents a foreseeable bridge solution to the forthcoming SOFC deployment

“…Further studies adopted this flexible point of view in planning deployment and relative storage systems [24], based on the location and its characteristics and on the energy system components (i.e. buildings) with which it interfaces [22,25].…”

Decarbonization of Residential Building Energy Supply: Impact of Cogeneration System Performance on Energy, Environment, and Economics

“…A multi-PM design strategy employing three ICE-based cogeneration systems for meeting the needs of 20 users has been shown to lower the fuel consumption compared to single equipment-based design [13]. Energy charge savings via hydrogen blended natural gas in a 5 kW el ICE-based micro-CHP was investigated and reported by Santoli et al [14]. Other heat engine-based cogeneration systems investigated included heat engines such as stirling (SE) [15], micro gas (MGT) [16] and steam turbines (MST) [17], suitable for a multi-family dwelling application.…”

Analysis of the Potential for Gas Micro-Cogeneration Development in Poland Using the Monte Carlo Method

“…Most of the ICE units use natural gas as energy source and this low fuel adaptability can be classified as disadvantage of those technologies. However, there are some studies, which considered alternative fuels (syngas form biomass [27] or hydrogen enriched with natural gas [28]) for ICE engines. Multi-fuel capabilities (mostly gaseous or liquid fuels) and high-grade waste heat are advantages of a small combustion turbines.…”
