Energy measurements at Skarpnes zero energy homes in Southern Norway: Do the loads match up with the on-site energy production?
2017
Five houses are designed as zero-energy homes in Skarpnes, Norway. The energy goal is to achieve net zero-energy balance on an annual basis. The houses have heat pumps and solar cells (PV). Energy use and delivered energy have been monitored from June 2015. Variations between calculations and measurements are explained by technical and non-technical reasons. For the first year, higher than expected energy loads result in a solar energy cover factor of 65–87% of delivered electricity. The PV generation performs satisfactorily, hence, it may be possible to achieve energy goals during later years provided technical adjustments or behavioral changes. Acknowledgements.

Lignin from steam‐exploded wood as binder in wood composites
2010
A study demonstrating the approach of zero‐waste technologies, a component of the Zero Emissions concept, and using lignin extracted from steam‐exploded wood as adhesive in hot‐pressed fibre boards and plywood to substitute phenol‐formaldehyde resins is reported. Properties of sample boards containing different amount of lignin adhesive are compared between themselves and with the EU standards for fibre boards. A strong correlation of density and form stability under humid conditions with the lignin content is found. Results of testing mechanical properties of the boards suggest that effect of lignin on mechanical strength depends on the size of particles and hot‐pressing temperature. Steam…
Integration of biorefinery clusters towards zero emissions
2008
Depletion of world recourses, increasing pollution, and climate change make us shift from linear economy to system economy an economy of technologies integrated to reach a non-polluting zero emissions production system. Transition to renewable resources requires replacement the present crude oil refinery by biomass refinery. Along with conventional biomass refinery technologies bioengineering and nano-technologies become significant players of systems in the design of clusters of integrated biorefinery technologies. The authors consider a number of case-studies of biomass conversion into value-added chemicals and sources of energy, the steam explosion autohydrolysis (SEA) in particular. Mod…
Zero Emissions and Bio-refineries for Natural Fibres, Biomaterials and Energy: Genesis of Concepts. Review
2015
Depletion of world recourses, increasing pollution, and climate change make us to shift from linear economy to system economy—an economy of technologies integrated to reach a system of non-polluting zero emissions production. Transition to renewable resources requires replacing the present crude oil refinery by biomass refinery. Along with conventional biomass refinery technologies bioengineering and nano-technologies become significant players in systems designed as clusters of integrated bio-refinery technologies.

The emission reduction potentials of First Generation Electric Aircraft (FGEA) in Finland
2020
Abstract Under the looming climate crisis, aviation needs to find new solutions to cut its greenhouse gas emissions. One pathway towards zero emissions is the use of electric aircraft. While current battery technology will not allow for medium and long-haul flights at full capacity, on short-haul routes First Generation Electric Aircraft (FGEA) could play a significant role in the near future. Current FGEA under development could carry 9–19 passengers on distances of 400–1046 km by 2025. This study focuses on the emissions reduction potentials of FGEA in Finland. It compares the carbon dioxide equivalent (CO2-eq) emissions and real travel times (RTT) from door-to-door of FGEA on 47 routes w…
A Feasibility Study for the Transition to Electric Mobility in the Island of Favignana
2021
The energy transition and climate neutrality are a short time scenario as climate concerns are rising fast. Small islands are natural microgrids in which the energy transition is subjected to economic and regulatory constraints and highly challenged by technical issues. As a first step, the Mediterranean island of Favignana has been considered in this study, to assess how electric mobility could impact the power system. According to the plans from the local decision makers, the island is moving towards a full public electric mobility in the near term, also due to the participation in the BloRin project. For this reason, a feasibility study about the technical and environmental impact of ele…
