In January of this year (2020), a major scientific study ('the Minshull report') announced that gas hydrate reservoirs were found in many offshore areas across Europe. The European Commission is now considering a policy view to commercialize the development and extraction of methane gas from European offshore areas. Affirmation from the European Commission that offshore methane hydrates are too useful and too valuable to forego development could initiate a global response to adopt offshore methane hydrates as a new source of natural gas for heating, for electrical power supplies, and for potential new revenues. The upside? The potential rewards from offshore methane hydrates are multi-fold. Coastal states are surrounded in methane hydrate resources that if responsibly developed could enable vast amounts of methane (natural gas) to be produced for decades or centuries beyond the timelines of conventional natural gas assets. There are also massive volumes of fresh water trapped in hydrates that could aid in fighting droughts and desertification. The downside? There are novel foreseeable risks that might result from those commercial methane hydrate activities. The climate change risks and geo-physical hazards from offshore methane hydrates are quite distinct from both conventional and unconventional hydrocarbons. There are new challenges to achieving safety and sustainability. In review, this paper both welcomes the discovery and confirmation of offshore methane hydrates in European waters and also raises concerns that more research is required on the optimal policy strategies for the known and foreseeable risks to best enable safe and sustainable policy choices.

Borealis is a recently discovered submerged mud volcano in the Polar North Atlantic, differing from the numerous methane seepages previously identified in the region. Here we show in situ observations from a remotely operated vehicle (ROV), capturing the release of warm (11.5 °C) Neogene sediments and methane-rich fluids from a gryphon at Borealis.

To date, only a few microbial community studies of cold seeps at the South China Sea (SCS) have been reported. The cold seep dominated by tubeworms was discovered at South Yungan East Ridge (SYER) offshore southwestern Taiwan by miniROV. The tubeworms were identified and proposed as sp.

A hydrogenotrophic methanoarchaeon, designated strain FWC-SCC4, was isolated from cold seep sediment of Four-Way Closure Ridge, offshore southwestern Taiwan. Strain FWC-SCC4utilizes H/CO or formate, but not acetate, secondary alcohols, methylamines, methanol or ethanol for growth and methane production. Yeast extract is required for growth.

CH production rate of coalbed methane (CBM) well decreases rapidly during primary recovery in the deeply buried coal seam, resulting in a lot of CH residues. CO pour into deep coal seam with high stress sensitivity is available for enhancing CH recovery by improving permeability for reservoir fracture and displacing CH adsorbed in matrix. A coupled adsorp-hydro-thermo-mechanical (AHTM) model for deep methane development is established by considering the coupling relationships of non-isothermal and non-constant pressure competitive adsorption between CO and CH, multi-phase flow, unsteady diffusion, heat transmission and in-situ stress variety.
