DNV GL identifies 3 technologies to reduce CO2 emissions

According to the company's "Technology Outlook for the Power and Renewables", in order to achieve fully decarbonization in the energy, trasport and heating field during the following 10 years, industry should pay attention on:

New battery storage chemistries

Solid-state batteries will take the lead for next generation electric vehicles, due to the high demand of decarbonizing the transport sector. In fact, solid-state battery technology has the potential to address most of the concerns with present-day Li-ion batteries. Made from solid electrolyte, solid-state batteries can have three times higher energy density and potentially double the cycle life of current Li-ion batteries.

High-temperature heat pumps

Next generation heat pumps to reach temperatures of 200°C degrees, may give a boost to the industrial heat demand. According to DNG GL, using heat pumps for space heating is not new. Although the goal to reduce CO2 emissions along with the increased use and excess supply of electricity, enabled this technology to be advanced.

According to company's research, technological advancement on heat pumps could follow the energy demands. It is said that these new types of high temperature heat pumps will be commercially available in 2023.

Green hydrogen

DNV GL reported that green hydrogen can compete against blue hydrogen until 2030, creating new applications for decarbonizing the heat and transport sectors.

Due to the increased demand of the green hydrogen's production, it is expected that the capital costs for electrolysers will drop and they will operate mainly when electricity prices are low.

Moreover, it is predicted that electrolysis will become a common part of hydrogen supply somewhere between 2030 and 2035.

With green hydrogen prices continue decrease, several countries are to implement it for heating applications, in order to decarbonize their building sector. Hydrogen has the potential to replace coal and gas for cleaner heating processes where electric heating with heat pumps or direct electric heating is not suitable.
